Mentzer and Becker (2011) and Becker and Mentzer (2012) demonstrated that high school students engaged in engineering design problems spent more time accessing information and spent more time designing when provided with Internet access. They studied high school students engaged in an engineering design challenge. The two studies attempted to apply the same research methodology as was used in previous work by Atman to facilitate comparison between high school students and experts. The 2011 study included Internet access, but the 2012 study did not. Their work showed that with Internet access, students spent an average of 137 minutes engaged in designing a playground and students allocated 47 minutes (35%) to information access. Without Internet access, similar students from the same schools on the same design problem spent an average of 92 minutes of which, 10 minutes (10%) was dedicated to information access. With limited computer access or limited time to enable students to access a computer in some classrooms, the research questions guiding this study are: (1) What information do high school students spend time accessing during an engineering design challenge? How much information comes from paper-based resources as compared to the Internet?; and (2) How much time do they spend accessing information? What is the balance of time spent accessing information from paper-based sources as compared to the Internet? Findings and implications of this research on student learning are discussed. Recommendations for future research are also offered. (Contains 5 tables and 1 figure.)

In many mechanical engineering undergraduate curriculums, there are topics that are vital to the students' future careers in the manufacturing and design workforce that are not taught in-depth. As one of those topics, Geometric Dimensioning and Tolerancing, or GD&T, is vital to companies who develop and manufacture products because it allows one to communicate with other team members in order to produce and inspect manufactured parts. GD&T is filled with intricate concepts that are hard to grasp without repetition and practice. An active learning intervention was developed and deployed in a mechanical engineering undergraduate class at the Georgia Institute of Technology. The active learning interventions were developed to assist students in learning basic manual inspection methods and communicating through a part drawing. The goal was for the students to obtain a foundational, hands-on understanding of GD&T and implement their learnings onto a part drawing and inspection plan. The results of this intervention were based on a Knowledge Assessment, self-reported Self-Efficacy Survey, and an Exit Survey. These assessments revealed that the GD&T intervention had a significant impact on the students' knowledgebase of the topic and their ability to perform identification and inspection tasks used in the workforce. This paper discusses the intervention structure and its potential applications for engineering education in the workforce.

This study investigated the influence of CThink4CS2 Module on computational thinking (CT) skills of form four chemistry students. The CThink4CS[superscript]2 Module integrated CT with the Engineering Design Process (EDP) in chemistry class. This study utilized quantitative research methods and quasi-experimental design. Quantitative data were collected using the Computational Thinking Skill Test (CTST) which consisted of algorithmic reasoning, abstraction, decomposition, and pattern recognition constructs. A total of 73 students were in the treatment group (n=39) and control group (n=34). Experimental data were described by means of descriptive analysis and inferential analysis employing two-way MANOVA analysis. The results of the analysis indicated significant differences in CT skills between groups; students in the treatment group demonstrated better results compared to those in the control group. The paper provides insight into the integration of CT and EDP as effective pedagogical strategies for inculcating CT skills.

With the advancement of specialized middle schools and high schools focusing on the arts, communication, engineering, mathematics, and science, many students who attend traditional schools miss out on valuable learning opportunities--in particular, when it comes to learning mathematics. Mathematics classrooms can be filled with real-world applications and concepts for all learners, regardless of the school environment. When teachers present middle school students with problems grounded in engineering principles, students will become active learners and will view mathematics as stimulating and useful. They will also learn that through mathematics, they can be innovative. The authors present an engineering project called "Paper Table," an investigation into building a sturdy table out of newspaper and cardboard. Engineering design projects provide an environment in which students can be active, inquisitive, and creative. Producing a paper table can lead to explorations of geometry and measurement. Concepts learned include (1) drawing and constructing polygons; (2) using a protractor to measure and draw specific angles in a polygon; (3) finding the areas of polygons; and (4) finding the surface area of three-dimensional figures. The "Paper Table" project challenges students to build a strong table that is 8 inches tall using newspaper, masking tape, and cardboard. The design requirements specify that the table must be sturdy enough to hold a heavy book. From a mathematical point of view, the "Paper Table" project revolves around properties of polygons and mathematical processes and practices. After producing models, students can ponder ways to find the area of the polygons that comprise the legs of the table. The "Paper Table" project gives students a challenge that can increase their interest in mathematics and let them recognize that engineering has many ties to the math that they study and use in class. Such STEM experiences are likely to excite, stimulate, and motivate students. The authors suggest It is time to include engineering projects in the classroom to allow today's students to embark on processes that they can develop into tomorrow's leaders in science, technology, engineering, and mathematics.

Developing a knowledge of design and construction technology and engineering is often overlooked in favour of 'digital' technology such as tablets and computers. By taking children outdoors into nature, removing tablets and computers as well as artificial and synthetic materials and replacing them with only what nature provides, children become attuned to developing STEM knowledge through play with natural materials. This knowledge often develops through teacher support and at times by default, as children experience the constantly changing landscape of the natural environment. The development of children's understandings of 'nature's' technology and engineering provides an opportunity for further investigation of nature-based early childhood education and care settings. Through research conducted at four Australian bush kindergartens, this paper presents data from photographs, interviews and observations undertaken of twelve teachers and over one hundred and twenty children. It responds to the research question, how do early years learners develop their understanding of technology and engineering by engaging in nature-based learning? The research was undertaken using ethnography, a useful method in nature settings as the approach enables a deep understanding of how children develop their understandings of applying technology and engineering over time. The data demonstrate the benefits preschool children can gain from learning and being 'in' and 'with' nature and the important role bush kinders play in supporting children's technological and engineering literacy. Findings reveal that through their participation in bush kinder, children can develop technological and engineering knowledge.

In this article, the authors explain how they leveraged the popularity of the "Star Wars" franchise to introduce a task steeped in popular culture as a fun way to engage their students in investigating complex mathematics that have real-life connections to careers in toy design and engineering design in general. The authors share various aspects of the multiday lesson to highlight the students' deep mathematical reasoning. The article starts with the introduction of the task, in which the authors challenged students to sketch a 2D prototype droid using paper and pencil, followed by creation of their 3D prototype using technology. The lesson includes the students computing the "cost" of the action figure they created.

Engineering has been considered as a useful context for successful implementation of STEM education. However, teachers have limited opportunities to develop a sound understanding about engineers and engineering, which is necessary for developing students' engineering practices and design skills. In this case study, the main purpose wasto examine 18 preservice science teachers' initial and final views about engineers and engineering in an undergraduate engineering-focused STEM course. Before and after an eight-week implementation including three engineering design activities, data were collected by the adapted version of Views on the Nature of Engineering Questionnaire and reflection papers. Findings revealed four categories: (1) views about engineers and engineering, (2) views about engineering design process, (3) views about the factors that affect engineering, and (4) views about science versus engineering. Based on the codes a scoring rubric was developed to categorize PSTs' views as uninformed, partially informed, and informed. Results showed that PSTs' views become more informed in each category. However, their views were still found as partially informed in some of the categories which shows the need for more emphasis on future research. The changes in their views were discussed with possible reasons and recommendations were provided for further studies.

This paper examines the differences and challenges encountered when trying to create informal blended (virtual and hands-on) engineering design STEM activities. It contrasts the creation of STEM activities for formal and informal learning environments, stressing that the differences extend far beyond the length of the activity or depth of any learning goals. The discussion begins with an examination of differences between the two learning environments that need to be taken into consideration. These differences include the physical environments, organizational structures, and the goals or reasons for the delivery of STEM activities in both environments. The paper continues by explaining why curriculum developers must be mindful of the context that will be implementing the activities, including space and time availability. The facilitators who deliver STEM activities are likely to have very different backgrounds in formal school settings compared to informal settings. Furthermore, it is important to recognize that youth in informal settings often push back when activities seem too "school-like." The paper concludes by presenting a detailed examination of the iterative process used to develop blended engineering design STEM activities in an informal setting. This process involved several revisions and tests of materials with youth in informal settings.

This paper presents the results of a 2-year longitudinal study aimed at characterizing and comparing the design cognition of high school students with and without formal engineering design experiences. The students--working as dyads--engaged in design-only sessions generating solutions in response to the same engineering design challenges. The design sessions were video and audio recorded, transcribed, then segmented and coded using the Function-Behavior-Structure ontologically-based design issues and design processes coding scheme. Both the design issues and design processes were described and compared between the two high school student groups. The results of this study revealed significant differences in design issues, processes, and the cognitive effort in their problem/solution spaces between the two high school student groups when the design sessions were partitioned in two and three equal contiguous fractions. The paper concludes with a discussion regarding the significance of the differences found in this study and their pedagogical implications.

Recent technologies are offering the power to share and grow knowledge and ideas in unprecedented ways. The CogEx software platform was developed to take advantage of the digital world with innovative ideas to support designers work in both industrial and academic contexts. This paper presents a qualitative study on the usage of CogEx during capstone design projects in mechanical engineering. It explores its potential to eventually supersede a paper logbook. This study combines three pilot projects where 15 undergraduate students used CogEx for one semester and discussed their experience in a final interview. The focus is limited to individual usage in this study. Results support that the platform has a good potential for engineering design education by replacing the paper logbook. The "extended concept mapping" structure was efficient to organize design work, and although the "concept-knowledge" separation needs refinement, it has good potential in building designer knowledge base.

A central part of basic engineering design education aims for imparting profound knowledge of how machine elements are designed and building an understanding about how they work in detail within a technical product. In this context, a basic challenge lies in teaching to analyse complex systems that are usually characterized by a high number of interacting parts and interfering movements. In our basic engineering design education at ETH Zurich, we recognized that high-performing students in functional analysis are able to gain more insights from analysing machine systems than low-performing students. Indeed, high-performers are not only effectively using previous knowledge, they are also more successful in identifying relevant parts. This observation raises two questions. (Q1) Which previous knowledge is required to single-handedly be able to fully understand how a specific system works? and (Q2) How can we support students in drawing special attention to the relevant parts and the areas revealing their role within the system? In order to answer these questions, we conduct a mobile eye-tracking study, including concurrent reporting. Students are asked to analyse a small, but difficult to understand machine system and to explain how it works. This paper highlights the differences between successful and non-successful functional analysis and discusses them in the context of the two questions presented above. The two main results of this paper are that successful students had a wider knowledge-base of mechanical systems and that analysis strategies like "following the flow line of force" gives a guide rail. Both helped them to identify single sub-functions and to evaluate their importance.

This paper investigates the effectiveness of the morphological chart method in design divergence. The literature presents the morphological chart as an engineering design method that does not particularly aim novelty, but instead gathers possible means for fulfilling the independently decomposed sub-functions of a product. On the other hand, implementations of this method in design education has shown that this method offers the possibility of design exploration for groups of interrelated sub-functions. Accordingly, this widens the solution space and encourages designers to think on the consequences of their design decisions while generating ideas, hence allowing situated design divergence to take place. The paper presents the findings of a review carried out on twelve morphological charts completed in groups, containing a total of 686 sub-solution sketches made for a pool of 21 sub-functions. The charts were reviewed as a whole in terms of group performance in idea generation for a decomposed design problem. Then the sub-solution ideas were grouped according to sub-functions and were reviewed in terms of idea content. It was seen that a background preparation with product trials, 3D exploration of product configuration, and experience in using the morphological chart method, affected the number of cells that the participants completed. Besides, several factors were found to influence the ways in which participants filled in the morphological charts. The reviews revealed eleven factors affecting design divergence using the morphological chart method, grouping under the headings of: preparations, group dynamics, boundaries of sub-functions, and interrelations of product components. In addition, thirteen strategies were identified that participants followed for idea generation using the morphological chart method, grouping under the headings of: beginning idea generation, ensuring effective idea generation, exploring ideas, diversifying ideas and representing ideas.

Purpose: The purpose of this paper is to understand how designers and engineers practice design while Making. Motivated by their roots in constructionist learning principles, Makerspaces are increasingly used as sites to learn design, especially in undergraduate engineering education programs. However, there has been little work on how trained designers Make and how design emerges in their Maker practices. Design/methodology/approach: In this paper, a conceptual framework is constructed to identify design practices within Making informed by theories of human-centered design and designerly ways of knowing. The framework is used to analyze narratives of ten experienced designers and Makers to understand how they enact design while they Make. Findings: The rich and compelling narratives of the participants support the proposed conceptual framework, providing qualitative evidence for how designers practice and know design while Making. This study also reports on a strong theme of realizing purpose and personal meaning while Making across the participants' narratives that sheds light on the unique and educationally meaningful value of Making, as in Making being a venue for agentive constructivist learning. Research limitations/implications: As an educationally meaningful practice, Making can be explored from several lenses, and this research solely uses a design lens. Practical implications: The motivations of the study are twofold. First, to understand how designers practice human-centered design and use design knowledge while Making. Second, to support the epistemological legitimacy of Maker knowledge by establishing connections with design knowledge. Originality/value: This paper contributes to the limited body of scholarly work to conceptualize experienced designers' Maker practices. Work in this area can inform learning outcomes and performance expectations in educational settings.

Purpose: The purpose of this study is to examine a week-long science, technology, engineering and mathematics (STEM) project-based learning (PBL) activity that integrates a new educational technology and the engineering design process to teach middle and high school students the concepts involved in rotational physics. The technology and teaching method described in this paper can be applied to a wide variety of STEM content areas. Design/methodology/approach: As an educational technology, the dynamic and interactive mathematical expressions (DIME) map system automatically generates an interactive, connected concept map of mathematically based concepts extracted from a portable document format textbook chapter. Over five days, students used DIME maps to engage in meaningful self-guided learning within the engineering design process and STEM PBL. Findings: Using DIME maps within a STEM PBL activity, students explored the physics behind spinning objects, proposed multiple creative designs and built a variety of spinners to meet specified criteria and constraints. Practical implications: STEM teachers can use DIME maps and STEM PBL to support their students in making connections between what they learn in the classroom and real-world scenarios. Social implications: For any classroom with computers, tablets or phones and an internet connection, DIME maps are an accessible educational technology that provides an alternative representation of knowledge for learners who are underserved by traditional methods of instruction. Originality/value: For STEM teachers and education researchers, the activity described in this paper uses advances in technology (DIME maps and slow-motion video capture on cell phones) and pedagogy (STEM PBL and the engineering design process) to enable students to engage in meaningful learning.

This paper presents findings from an on-going international study of Early Childhood (EC) teachers' and children's use of Internet of Toys (IoToys) to understand possibilities for developing children's cognitive capacities (e.g., creativity, inquiry, engineering design thinking). The study employed a Design Based Research (DBR) method, where teachers intentionally plan and deliver technologically constructed Science Technology Engineering and Mathematics (STEM) experiences for preschoolers. Using Australia as a case study, data collection involved participant observation of three teachers' and 17 children's technology constructed play experiences with robotic toys, littleBits electronic magnetic blocks, alongside pre and post semi-structured interviews with teachers and children's photo voice sessions were video recorded. Analysing the findings using embodied cognition theory showed that the teachers, although novice in their own technological pedagogical knowledge engaged children's play with the robotic toys, and co-learn with the children. Integration of STEM-focused playful experiences supported children's scientific inquiry, design thinking and creativity as well as vocabulary targeted at interdisciplinary STEM concepts. With the ever increasing focus on developing children's 21st century skills, this study recommends engineering habits of mind, creativity and inquiry dispositions should now be taken into account in teaching and learning situations with young children and to develop STEM engagement.

Preschool environments offer an abundance of opportunities for exploring the physical world where children can learn "engineering concepts" and "principles" (theories or laws). Yet how teachers design motivating conditions for engineering thinking has not been fully investigated. The study reported in this paper examined how teachers and young children engaged in engineering principles over 12 months. Digital video observations (123 h) captured the daily interactions of two teachers and 13 children across two classrooms during their engineering sessions. The participants were 8 preschool children aged 4.7-5.5 years and 5 school children aged 5.5-6.4 years. Different to previous studies that focus on engineering affordances during free play, the results identify new play pedagogies that support personally meaningful engineering learning of children in preschools. The new practices, named as an "Engineering PlayWorld," build imaginary situations, where children in teams act 'as if' they are engineers, meeting engineering problems and generating engineering solutions.

Purpose: The researchers conducted a collective case study to investigate how families engaged in making activities related to aerospace engineering in six pop-up makerspace programs held in libraries and one museum. The purpose of this paper is to support families' engagement in design tasks and engineering thinking, three types of discussion prompts were used during each workshop. The orienting design conjecture was that discussion prompts would allow parents to lead productive conversations to support engineering-making activities. Design/methodology/approach: Within a collective case study approach, 20 consented families (22 adults, 25 children) engaged in making practices related to making a lunar rover with a scientific instrument panel. Data included cases of families' talk and actions, as documented through video (22 h) and photographs of their engineering designs. An interpretivist, qualitative video-based analysis was conducted by creating individual narrative accounts of each family (including transcript excerpts and images). Findings: Parents used the question prompts in ways that were integral to supporting youths' participation in the engineering activities. Children often did not answer the astronomer's questions directly; instead, the parents revoiced the prompts before the children's engagement. Family prompts supported reflecting upon prior experiences, defining the design problem and maintaining the activity flow. Originality/value: Designing discussion prompts, within a broader project-based learning pedagogy, supports family engagement in engineering design practices in out-of-school pop-up makerspace settings. The work suggests that parents play a crucial role in engineering workshops for youths aged 5 to 10 years old by revoicing prompts to keep families' design work and sensemaking talk (connecting prior and new ideas) flowing throughout a makerspace workshop.

This paper regards the mechanical curriculum teaching as a design problem and uses environment-based design (EBD) method to solve it. First, environment components and their relations of the mechanical curriculum are found out by recursive object model (ROM). Then, conflicts in the teaching process are identified by analysing the above relations. Finally, solutions for solving these conflicts are generated. The proposed method is applied to mechanical manufacturing technology foundation (MMTF) curriculum with 217 students in grade 2016 in China. The solutions used in MMTF include decreasing the mental stress of students, developing more experimental projects, applying real cases and projects, adopting variety of assessments and so on. Compared with the performance of students in grade 2015, the average attendance rate and final scores are both increased, and three of the four achievement values of graduation attributes are risen. The practical example illustrates the EBD method is effective in improving curriculum teaching.

Purpose: This study aims to investigate how the processes of memory acquisition, retention, retrieval and application occur in project-based organizations (PBOs). In this kind of organization, the nature of corporate memory is influenced by the transience, uniqueness and independence of the project portfolio. Such understanding may help practitioners to mitigate the effects of project transience and promote knowledge sharing among project teams. Design/methodology/approach: An empirical and qualitative study was carried out through a multiple case study approach conducted in three Brazilian Engineering Design Firms, which are organized by projects. Document analysis, direct observation and semi-structured interviews with engineers, project managers and executives were conducted. Findings: The memory acquisition process takes place in five forms which have different sources and destinations when comparing PBOs with traditional organizational settings. Memory retention in PBOs crosses organizational boundaries and establishes a knowledge network of former employees and third parties. The PBOs project memory can be divided into volatile and perennial memory, where the former can be lost throughout project execution and the latter is internalized, becoming an inseparable part of the corporate memory. Memory retrieval in PBOs is also distinct since it has particular mechanisms depending on whether the knowledge is technical or administrative. Originality/value: The research investigates the corporate memory processes within the volatile context of PBOs in a Latin-American developing country whose culture favors tacit knowledge exchange. The paper proposes a framework that unveils different patterns of knowledge acquisition, temporary and perennial retention structures, intensive usage of external knowledge in memory retrieval and particular memory applications in PBOs. The framework may guide scholars, project managers, engineers and practitioners in navigating through the uniqueness of organizational learning flows and structures in PBOs.

Background: Understanding the nature of engineering is important for shaping engineering education, especially precollege education. While much research has established the pedagogical benefits of teaching engineering in kindergarten through 12th grade (K-12), the philosophical foundations of engineering remain under-examined. Purpose: This conceptual paper introduces the honeycomb of engineering framework, which offers an epistemologically justified theoretical position and a pedagogical lens that can be used to examine ways engineering concepts and practices are taught in precollege education. Scope/Method: The honeycomb of engineering was developed as a descriptive framework by examining existing literature over a wide range of related disciplines such as the philosophy of engineering and technology, as well as design thinking and practice. The pedagogical translation of the framework was then developed to examine published precollege engineering curricula. Results: The framework categorizes the multiple goals of engineering using an ontological classification of engineering inquiries anchored in the central practice of negotiating risks and benefits (i.e., trade-offs). This framework also illustrates the adaptability of design methodology in guiding six inquiries: (1) user-centered design, (2) design-build-test, (3) engineering science, (4) optimization, (5) engineering analysis, and (6) reverse engineering. The published curricula represented these inquiries with varying degrees, with design-build-test lessons seeing the most representation followed by user-centered design. Conclusions: The honeycomb of engineering framework delineates variations in engineering education based on an epistemological explanation. The pedagogical translations offer guidance to educators, researchers, and curriculum designers for differentiating curricular aims and learning outcomes resulting from participation in different engineering inquiries.

This paper presents the assessment items that were developed by science and technology teachers in Québec to explore their students' alternative ideas about engineering design technology and technological systems. These assessment items were administered to Secondary Cycle One students in Francophone and Anglophone schools in Québec to elicit their ideas about the foundational technology concepts included in the science and technology curriculum. Students' responses are presented to share their alternative and scientific explanations. In addition, various approaches to facilitate a deeper understanding of scientific models and mechanistic reasoning in students are also discussed.

High level, abstract engineering thinking and design is a subject that is hardly addressed in current curricula for secondary education. This is contradictory to the increasing need for more in depth STEM education in secondary schools dictated by the evolution of our society towards an ever more STEM based information society. In this paper an approach is presented to introduce 16 year old Belgian pupils to some of the most important, basic concepts of control theory. Control theory is here exemplary for more general engineering science. The problem used to introduce control theory is that of heating system design in houses.

This paper describes a study of students' meaningful learning of the engineering design process during their participation in robotics activities. The population consisted of middle-school students (ages 13-15 years) who participated in the FIRST® LEGO® League competition. The methodology used was qualitative, including observations and interviews. The analysis was based on the Revised Bloom Taxonomy. Almost all the groups demonstrated meaningful learning, although some reached higher levels than others. Most of the groups demonstrated the understanding/applying level during each of the design process phases (searching and decision making, construction and testing, diagnosing and debugging), some demonstrated the analyzing/evaluating level, but only a few demonstrated the higher level of creating. Factors that seemed to play a role in the students' learning include: (a) the teaching or mentoring style; (b) the absence of a robotics textbook; (c) the extra-curricular competition-oriented nature of the activities; and (d) the unstable nature of the design of the robot.

The development of vital competencies and a mindset to rethink products, production, and business models in engineering and design students is presently of great importance. These future professionals will play a key role in the development of sustainable products. Within Eco-design and Eco-efficiency curricular unit, an assignment was developed that consisted of the development of an eco-design and eco-efficiency study of a given product, provided by a real industrial company. In this paper, the challenge description and application are reported, as well as the key conclusions.

Contribution: This paper found that design experiences can foster engineering identity and belongingness for early career electrical and computer engineering students. Students had different interpretations of what it meant to be an engineer (identity) and their belongingness in engineering. This paper provides novel insights into how students may be developing identities and belongingness in engineering, both critical for student retention and success. Background: Design experiences are crucial for engineering students, both for developing academic competencies and allowing students to see how they can become engineers. Existing literature has mixed results with respect to the influence of team-based design experiences on engineering identity and belongingness. Research Questions: 1) How do design experiences influence early career electrical and computer engineering students' identification and belongingness in engineering? and 2) How do these students describe what it means to identify as an engineer and belong in engineering? Methodology: The beliefs of electrical and computer engineering students were examined using mixed methods to understand the intersection of design experiences, engineering identity, and belongingness. Findings: Students interpreted their engineering identity and belongingness differently, particularly, with respect to how design experiences can shape these attitudes. Whereas students interpreted engineering identity through their performance and interest in authentic engineering tasks, they interpreted belongingness as a means of comparing themselves to their peers. The findings have implications for engineering education researchers, and design instructors, to foster ways of being and belonging in engineering.

This study examines the development of a STEM-based (Science, Technology, Engineering, and Mathematics) and parent-involved engineering design curriculum for early childhood education and investigates its design principles and contributions to children's STEM-related learning. This research utilized a design-based research methodology broken into three main phases (preliminary research, prototyping, and assessment). The data were gathered over a 2-year span, and the curriculum was designed and revised during the prototyping phase's three iterative cycles. This paper presents the findings of a field test that involved two early childhood education teachers, five preschool children, and five parents. Findings validated eight key design principles of the curriculum and revealed that the curriculum contributes to the knowledge, skills, feelings, and dispositions children have towards STEM. The findings suggest that the developed curriculum can be used as a novel way of integrating STEM into early childhood education, with a particular focus on engineering, while encouraging parental involvement.

Learning analytics and educational data mining are introducing a number of new techniques and frameworks for studying learning. The scalability and complexity of these novel techniques has afforded new ways for enacting education research and has helped scholars gain new insights into human cognition and learning. Nonetheless, there remain some domains for which pure computational analysis is currently infeasible. One such area, which is particularly important today, is open-ended, hands-on, engineering design tasks. These open-ended tasks are becoming increasingly prevalent in both K-12 and post-secondary learning institutions, as educators are adopting this approach in order to teach students real-world science and engineering skills (e.g., the "Maker Movement"). This paper highlights findings from a combined human-computer analysis of students as they complete a short engineering design task. The study uncovers novel insights and serves to advance the field's understanding of engineering design patterns. More specifically, this paper uses machine learning on hand-coded video data to identify general patterns in engineering design and develop a fine-grained representation of how experience relates to engineering practices. Finally, the paper concludes with ideas on how the specific findings from this study can be used to improve engineering education and the nascent field of "making" and digital fabrication in education. We also discuss how human-computer collaborative analyses can grow the learning analytics community and make learning analytics more central to education research.

This position paper sets out to examine value creation in the engineering enterprise, a process that has mostly been associated with innovation and entrepreneurs. An analysis of the literature on engineering value creation in business studies, engineering and engineering education publications shows that there has been surprisingly little empirical study and thus the means by which most engineers contribute value is unclear in the literature. Analysis of published data and data from studies by the authors in engineering workplaces in Australia, South East Asia and Portugal suggests that the work performed by most engineers has little to do with innovation. Based on these data the authors identify 14 ways in which engineers create value. An important finding is that routine engineering performances by a majority of engineers, not associated with innovation or entrepreneurial activities, not only can be shown to create value, but also to protect accumulated value from inadvertent destruction. The paper outlines the educational implications of these findings and proposes measures that engineering educators can adopt to improve the understanding of engineering graduates about engineering value creation.

Many physics teachers have experienced the challenges of implementing the Next Generation Science Standards (NGSS) in their high school curricula. These standards, based upon the Framework for K-12 Science Education, were intended to shift science instruction towards an interdisciplinary focus on three-dimensional learning, phenomena anchored explorations, and developing solutions for technological problems. The present paper describes a collaboration between electrical and computer engineers and physics educators, whereby a physics unit was created to embed engineering practices in the design of a night light. Although the project also incorporates aspects of crosscutting concepts and disciplinary core ideas, we focused on engineering practices since more educational resources are needed that illustrate this aspect of NGSS-aligned teaching and learning. The unit was piloted with over 1500 high school students in an informal outreach program, as well as professional development workshops for 100 secondary science teachers, with the intent that teachers would incorporate this and other engineering projects in their physical science classrooms.

Purpose: This paper aims to compare two types of prompts, encouraging participants to think about real-world examples or engineering principles to show how these two approaches can result in vastly different design practices. Design/methodology/approach: Two studies (N = 20, N = 40) examine the impact of two different prompts. Non-expert students, from high school and university, completed a hands-on, engineering design task in pairs. Half were prompted to ideate using real-world examples, while the other half were prompted to ideate using engineering principles. The findings are based on human coding and artifact analyses. Findings: In both studies, and across multiple measures, students in the principle-based condition performed better than students in the example-based condition. Research limitations/implications: A seemingly small difference in how students are prompted or encouraged to approach a problem can have a significant impact on their experience. The findings also suggest that leveraging engineering principles, even when those principles are only loosely formed, can be effective even for non-experts. Finally, the findings motivate identifying student reasoning strategies over time as a potential means for assessment in Makerspaces. Practical implications: Encouraging makers to think about different ways for approaching problems can be an important way to help them succeed. It may also be a useful way to chronicle their learning pathway. Originality/value: To the author's knowledge, explicitly looking at ideation strategies has not been widely discussed within the Maker community as a way to support learners, or as a way to evaluate learning.

This paper reports on findings from a group of ten teachers who were enrolled in a semester-long, graduate-level educational technology course that used design-based learning to explore the integration of making and the engineering design process into a variety of K-12 educational contexts. Using convergent mixed methods, this study examines how the course impacted teachers' familiarity and confidence in teaching the engineering design process, as viewed through their pre- and post-semester engineering design self-efficacy scores and their weekly reflective journal entries. These measures are important factors for developing teacher experience and confidence in integrating engineering and design-based learning strategies within K-12 educational contexts. Statistically significant results include increased confidence in design and decreased anxiety toward design. Findings illustrate how participants acknowledged increased familiarity and confidence in teaching the engineering design process, including their increased ability to make connections to the engineering design process, maker tools, and techniques. Implications for teacher education programs are discussed.

Inequities in opportunities to learn and become in engineering, especially for minoritized youth, are enduring and systemic. How students experience engineering education, through curriculum, pedagogy, and teacher/student interactions, all shape opportunities for identity development. In this paper we draw upon cultural studies and critical ethnography to explore how and why students engage in engineering for sustainable communities and its relationship to their identity work. We ground our work in a justice-centered asset-based stance that centers how people's lived lives and community wisdom yield powerful forms of cultural knowledge/practice relevant to learning and engaging in science, technology, engineering, and mathematics. We seek to accentuate students' ingenuity to leverage their assets for social change making; that is, in transformative and future-oriented ways. We view youths' everyday ingenuity as powerful assets for learning and participating in authentic engineering design for sustainable communities. Findings suggest that engineering for sustainable communities created opportunities for productive identity work because it created space for youth to authentically engage in engineering design in ways that allowed them to care about each other, their classroom and community, and to use both their everyday ingenuity and technical expertise to make a difference. We also suggest that students' identity work took shape through the emergence of new local contentious practices of engineering for sustainable communities that both amplified youths' ingenuity and challenged particular local, historical/sociocultural norms of engineering and schooling. These contentious local practices related to disrupting the authority to name what counts as engineering problems worth solving and disrupting narratives around what it means to persist through iterations in design. We suggest that an engineering for sustainable communities approach supports the production of local and productive contentious practice because it centers community co-ownership in the design, and supports students in leveraging their everyday ingenuity as critical knowhow in engineering design.

The research reported on in this paper addresses the problem of preparing Massachusetts middle school mathematics, science, and computer teachers to teach engineering. The results presented here are part of a larger dissertation study investigating six urban public school teachers and their subject matter and pedagogical content knowledge teachers know and develop as they taught an engineering unit. The results discussed in this paper focused on the teachers' instruction and knowledge of the central aspects of the engineering design process (EDP)--the purpose of the EDP, that the EDP is a cyclical, iterative process, and that the EDP fosters communication. The analysis of the videotaped classroom observation data revealed that the teachers as a group covered the central ideas regarding 1. "Purpose of the EDP" and 2. "EDP as a cyclical process" quite well. Every teacher touched upon at least one of the sub-ideas for these two central ideas. The teachers did not cover 3. "EDP for fostering communication" well. Only Frieda and Monica conveyed anything regarding this idea to their students. This paper explores each central idea and the teachers' understandings of them as expressed through their explanations in the classroom observations and follow-up interviews.

In this paper we describe the development and refinement of "evidence rules" and "measurement models" within the "evidence model" of the "evidence-centered design" (ECD) framework in the context of the "Packet Tracer" digital learning environment of the "Cisco Networking Academy." Using "Packet Tracer" learners design, configure, and troubleshoot computer networks within an interactive interface. This leads to "product data," which result from the students' final submitted network configurations, and "process data," which are log file entries detailing how they got to the final configurations. We discuss how an iterative cycle of empirical analyses and discussions with subject-matter experts is essential for identifying and accumulating evidence about skill profiles of learners and their development. We present results from descriptive, exploratory, and confirmatory diagnostic modeling analyses for both data types, which required bringing to bear a diversity of tools from multivariate statistics, modern psychometrics, and educational data mining. We close the paper with a discussion of the implications of this work for evidence-based argumentation guided by ECD principles within digital learning environments more generally.

Capstone engineering design courses have been a feature at research universities and four-year schools for many years. Although such classes are less common at two-year colleges, the experience is equally beneficial for this population of students. With this in mind, Madison College introduced a project-based Engineering Design course in 2007. This paper explores Madison College's experience over the past decade offering this class. Unique challenges and opportunities for engineering design courses at two-year colleges are discussed. Our findings include several recommended practices to benefit colleges and universities at any level that are creating new engineering design courses.

This paper resulted from discussions between a technology teacher educator and a colleague who has served in various education outreach roles with NASA. The basis of the paper was developed by the NASA director and two engineers, one serving with NASA and the other with the National Institute of Aerospace. The technology teacher educator read the original paper as published in the NASA Technical Report Server (NTRS) and realized that, though it addressed an audience of engineers, its implications for technology educators were obvious. As evident in the paper, the engineering community seeks a means to reach into the K-12 curriculum at the same time that leaders in technology education are promoting design and engineering in their curricula nationwide. This revised version of the engineering paper with added implications for technology education provides support for current trends in their profession and shows how the linkages can best be implemented. The authors hope that the perspective from the community of engineers shared in this paper will lend support to those leaders in technology education who are working to include engineering, resulting in the development of a fuller context for their arguments and providing some useful ideas as to how engineering can be included without eliminating the positive outcomes of contemporary technology education and the industrial arts of yesteryear from which it evolved.

This paper describes the first part of a new three-part study of STEM and engineering design research termed Design-Without-Make to be conducted by NC [North Carolina] State University in 2009-10 in an NC high school. The hybrid quantitative, qualitative case study is being developed with the purpose of capturing what new technological learning occurs and how the new pedagogical learning benefits the technological learner. In support of this new design research a three-pronged framework is described, that of basic literature review, social learning theory and project-based learning study. This first paper also includes a description of proposed data collection, analysis, and limitations of the study, and concludes by presenting the implications for Design-Without-Make. Two further papers in the sequence will go on to explain the pilot study and the final study including data results and findings for this new approach to teaching engineering design technology within STEM education.

With the inclusion of engineering disciplinary core ideas (DCIs), the Next Generation Science Standards (NGSS) position engineering as a new priority in K-12 science classrooms. This paper reports findings from the implementation of SLIDER, a problem-based learning 8th grade physical science curriculum that integrates engineering and physical science core ideas. As a culminating engineering design challenge, the SLIDER curriculum asks students to apply their understanding of energy, motion, and forces to design an automatic braking system for a robotic truck. The paper describes the curriculum and synthesizes findings from an array of data sources including student design interviews, written design recommendations, engineering notebooks, pre- and post-assessments, and teacher interviews to address two research questions: (1) To what extent and in what ways do students participating in the SLIDER curriculum engage in NGSS engineering DCIs: defining problems, developing solutions, and optimizing solutions? (2) To what extent and in what ways do students draw upon their understanding of science concepts as they engage in engineering design? Findings indicate variations in the degree to which students participating in the SLIDER curriculum engaged across the three NGSS engineering DCIs, with students generally demonstrating competency with regard to identifying and delimiting the engineering problem (ETS1.A) and, to varying degrees, developing solutions (ETS1.B) but experiencing more challenges engaging in the optimization of design solutions (ETS1.C). Findings also illustrate the degree to which students were able to apply their knowledge of relevant physical science core ideas (e.g., friction, force) as they developed and communicated their solutions. Implications of the findings for instruction, curriculum development, and assessment are discussed.

Engineering Graphics and Design is a technological subject which is offered in the Bachelor of Education degree from third to fourth year of the degree course. Fourth year pre-service teachers find EGD difficult to teach because of various reasons. Therefore the aim of the paper was to investigate fourth year pre-service teachers' pedagogical content knowledge gaps in teaching EGD during their teaching practice. The study was conducted using a qualitative approach and eight pre-service teachers were purposefully selected to take part in the study. Findings of the paper found that pre-service teachers found teaching practice very short to do all the teaching tasks that is required of them. Some pre-service teachers did not have drawing models to make learning concrete to their learners. Assessment was done partially just to impress the university tutors and to conform to the schools' rule and not to evaluate the learners' understandings and their teaching.

"Standards for Technological and Engineering Literacy" ("STEL") promotes science, technology, engineering, and mathematics (STEM) education, where technology and engineering play a critical role as subject integrators. Integration of STEM in project-based learning is an ideal approach, with benefits of enhancing student learning and 21st-century competencies. Contemporary educational reform requires science and engineering practices to be integrated and suggests that this integration should be explicit (International Technology and Engineering Educators Association [ITEEA], 2020; NRC 2012). However, teachers often experience challenges while presenting STEM content using an integrative approach. For a successful implementation of integrated STEM, teachers need to be informed about how to integrate STEM contents while also using essential pedagogical approaches. This article proposes an integrated STEM lesson titled "Designing Bugs and Innovative Technology" ("D-BAIT") as a practical and feasible model that high school STEM teachers can adopt in their classrooms. The "D-BAIT" lesson, developed by STEM researchers within a national STEM education project, teaches high school students engineering design using biomimicry, life science, and mathematics. This paper analyzes the "D-BAIT" lesson based on "STEL" and addresses how well the lesson aligns with project-based and problem-based instruction. The "D-BAIT" lesson will inform how design instruction can be blended into science and engineering practices, which will guide STEM teachers and educators to create and implement integrated STEM lessons.

Introduction: Genre analysis is an approach to study communication patterns and thus it can be applied to the specific context of meetings. This research investigates the use of genre analysis in the design of electronic meeting systems. Background: The primary goal of genre analysis is to understand how virtual communities use digital communication to collaborate. This knowledge is fundamental for informing the design of information systems, particularly in areas where communication and informality are paramount. However, the research literature does not report any experiments where genre analysis has been used to inform the design of electronic meeting systems. Problems: The paper tackles the following common problems found in current electronic meeting systems: (1) reduced organizational integration, neglecting many contextual cues and explaining factors necessary to make meeting outcomes usable within the organization; (2) lack of support to specific communities of users, stressing the dependency on a facilitator to configure and manage the technology; and (3) lack of support to meeting occurrences that span long time periods. Conclusions: The paper describes how genre analysis was used to develop electronic meeting systems for several organizations and meeting genres. It covers the complete design process, from genre elicitation to validation. The obtained results demonstrate that the genre approach produces electronic meeting systems focused on organizational integration, pre-configured to communities of users, supporting long-term usage and added organizational value.

The article discusses the aspects to be considered in the art of designing pop-ups, called paper engineering. The author explains that the challenge associated with the most elaborate pop-up constructions is achieving the total vision which entails a combination of mechanics, architecture, and visual image that unite into a magical world-on-a-page. The more knowledgeable an artist about mediums and production processes, the more satisfying the results. The author shares her own foray into the art of the pop-up that started after graduating from Washington University's School of Fine Arts as a painting major.

Engineering design is a complex process both for students to participate in and for instructors to assess. Informed designers use the key strategy of conducting experiments as they test ideas to inform next steps. Conversely, beginning designers experiment less, often with confounding variables. These behaviours are not easy to assess in educational settings because they occur throughout the design process. This paper reports on a two-fold study carried out to test the model for identifying student behaviours during design experimentation. The first phase uses the process data from 48 middle-school students designing an energy-plus house. The study utilized learner interaction data sets collected through automatic, unobtrusive logging of student actions in a CAD platform. The analysis of learner process data is compared to student performance on an open-ended post-test. The second phase correlates the number of experiments students conducted to the quality of student prototypes. The results suggest that the proposed model can be used to identify, characterize, and assess student strategies associated with conducting experiments. Implications of this work are relevant to engineering and design educators as well as researchers interested in the role of learning analytics in studying complex processes.

Bioengineering represents an interdisciplinary field with the potential to engage young learners in science inquiry and engineering design in the context of real-world challenges. Although children encounter bioengineered products and solutions in their everyday lives, they are not introduced to bioengineering until much later in school, after stereotype threats about STEM engagement have crystallized. The purpose of this paper is to present an experimental tangible tool called CRISPEE and evidence from an intervention with young children who explored CRISPEE in the context of an informal bioengineering curriculum. In this design study, 25 children aged 4-7 years engaged in a 9-h workshop designed to introduce them to foundational bioengineering concepts of gene editing, engineering design, and bioethics. Children's attitudes and content knowledge about life science, engineering, and bioengineering were assessed pre- and post-interventions. Mixed quantitative and qualitative results show that most children entered the intervention with pre-existing ideas about genes and attitudes about engineering and science. Post intervention, children demonstrated increased positive STEM attitudes and content knowledge, especially in the area of science inquiry, and also demonstrated an emerging curiosity about the purpose and effectiveness of bioengineering work, including bioethics. Implications for research and practice are discussed.

Novice design students struggle to engage with early stage design visualization tools such as sketching and prototyping. Instead students have a preference for designing with digital tools such as CAD modelling, motivated by inhibitions around sketching skill, which in turn leads to fixation and sunk cost effects. These behaviors present a barrier to engaging in typical practices of expert designers, namely idea fluency described as generating a wide range of ideas quickly and avoiding favoring one single idea. Noting the recent success of LEGO Serious Play in engaging non-designers in design activities in business and innovation contexts, we explore whether using LEGO as a visualization tool can trigger a behavior change in student designers towards idea fluency. This paper presents a study comparing student attitudes and design behavior when designing with LEGO, in comparison to sketching and cardboard modelling. Findings illustrate how LEGO's comparative low fidelity leads to students to be more willing to change and modify initial ideas, reduces inhibitions related to visual quality, and reinterpret and iterate designs. Based on these findings we illustrate how designing with LEGO can mitigate issues of inhibition, fixation, and sunk cost design behaviors concluding that LEGO can trigger behavior change toward idea fluency. As such we see compelling evidence to integrate LEGO as an educational design activity for novice designers used early in the design process to illustrate and trigger idea fluency.

In this paper, we examined students' engagement in an implementation of a Workplace Simulation Project (WSP). The WSP was designed to actively engage students in learning disciplinary content by inviting engineers from industry to have a physical presence within the school building to collaborate with teachers and students to complete projects which simulate the tasks authentic to their work. We focus on the first year implementation of the program that partnered a high school in the rural Midwest with an engineering unit of a government organization. Using a multiple methods study design, we analyzed disciplinary and interdisciplinary pre and posts test along with students' interviews to determine learning gains as well as students' interpretations of creative and critical thinking as experienced in the project and their knowledge of the engineering design process. Effect sizes showed that students in the WSP group had notable gains over the control group participants. Additionally, students' knowledge of core elements of the design process were identified in inductive analyses of the interviews. Findings from this study will provide usable knowledge about effective ways to support systems and design thinking and ways to support expert-novice collaboration to ensure success.

People who practice engineering can make a difference through designing products, procedures, and systems that improve people's quality of life. Literacy, including the interpretation, evaluation, critique, and production of texts and representations, is important throughout the engineering design process. In this commentary, the authors outline texts and interpretive frameworks that are common to each stage of the engineering design process as it is defined by the Next Generation Science Standards. The authors describe how disciplinary literacy can also account for students' home languages and local bodies of knowledge, in addition to these engineering design standards. Finally, they conclude with a vision of disciplinary literacy as a tool to promote equity by rigorously supporting diverse students through the process of critiquing designs in society and creating ethical and equitable designs.
