Reading primary research literature is an essential skill for scientists. However, the high complexity of research papers may pose a barrier to the development of scientific literacy. In semi-structured interviews, we explore how 33 biologists including undergraduates, postgraduates and researchers approach reading an unfamiliar scientific paper. We find that some readers are data-centric, focusing on their own critical evaluation of the data presented, whereas others adopt a more narrative-centric approach, relying on the descriptions of authors to inform their understanding. There was a bias towards undergraduates adopting the narrative-centric approach and researchers adopting the data-centric approach. All postdoctoral researchers and academics prioritised critical interpretation of the data, indicating this is a characteristic of experienced scientific readers. The ability to demonstrate scientific reading skills was context-dependent, particularly with respect to time available and whether a paper aligns well with a reader's specialist area of knowledge. Inexperienced readers often lacked sufficient prior knowledge on which to base their reading, which represented a barrier to their engagement. We make recommendations for how scientific literacy should be developed within undergraduate teaching and beyond, noting that 'one-off' teaching strategies are insufficient when the development of scientific reading skills is a career-long process.

This article presents a simple, cognitive theory of science and learning. The first section of the paper develops the theory's two main propositions: (i) A wide range of scientific activities rely heavily on one type of reasoning, hypothetical thinking, and (ii) This type of reasoning is also useful to students for learning science content. The second section of the paper presents a taxonomy of multiple-choice questions that use hypothetical thinking and the third section of the paper tests the theory using data from a college biology course. As expected by the theory, student responses to 24 scientific reasoning questions were consistent with a one-dimensional psychometric construct. Student responses to the scientific reasoning questions explained 36% of the variance in exam grades. Several directions for additional research are identified, including studying the psychometric structure of scientific thinking in more detail, performing randomized, controlled experiments to demonstrate a causal relationship between scientific thinking and learning, and identifying the relative contribution of other factors to success in college.

Students often come to college with a limited understanding of how to ethically incorporate and cite source materials in their writing, and this is commonly cited as the leading reason for plagiarism. Studies have shown that students in STEM are more apt to plagiarize as compared to students in the humanities or social sciences, so they are an ideal population for looking at causes of plagiarism. The goal of this study was to examine college STEM student self-reported frequencies of plagiarism, ability to recognize instances of plagiarism, and justifications for why certain acts of plagiarism may or may not be acceptable. Surveys were collected from 965 STEM students taking an introductory biology class. The majority of freshmen surveyed admitted to some degree of plagiarism and found it difficult to recognize certain types of plagiarism. Juniors and seniors were less likely to report any form of plagiarism and are better able to recognize specific types, supporting previous work that point at lack of experience as the reason for most plagiarism in college. However, students at all levels were confused about the acceptability of some examples of plagiarism, such as reusing the same paper in multiple classes and some students point to external factors like grading practices in previous courses as motivators for certain types of plagiarism. Fully understanding where students still struggle to recognize plagiarism and their motivations for committing certain types of plagiarism will help in creating strategies to mitigate this common problem.

There is much anecdotal evidence of the benefits of fieldwork, but a small amount of research has been carried out on the value of fieldwork for student learning. Existing studies have focused on analysing fieldwork in mostly disciplinary and national contexts and the effects of interdisciplinary fieldwork on student learning have not been fully analysed. This paper aims to fill this gap by providing empirical evidence of the impact interdisciplinarity and internationality have on student learning while carrying out fieldwork. The case study consists of three field courses in Portugal in which biology, geography and geology students from Germany and Portugal took part. Based on a group interview with twelve students, their experiences, perceived learning outcomes and overall success of the fieldwork are evaluated. The results support the initial assumptions that interdisciplinary and international fieldwork adds value above and beyond the traditional field experience, and has a positive effect on the learning experience of the students. The students agree they have learned to better define their own study field and the interconnections with other disciplines. They also reported improved communication skills and methodological abilities and now feel better prepared to meet academic challenges and careers beyond campus.

Although most students in nonmajor biology courses will not enter careers in science, they will need a working understanding of biology and how it relates to their lives to make informed decisions on important topics that will affect their lives, including food, environment, energy, and health. This research seeks to improve on nonmajors' understanding of biology and how it relates to their personal lives. This study was conducted in a biology course for nonmajors at a large urban university in the mid-South. Students were asked to provide written responses and thoughts on a curated set of popular science articles. Student participants provided a total of three article reviews and two reflection papers over the course of 1 semester. These data were qualitatively coded and assessed for recurring themes both on an individual student level as well as across student cases. Our findings suggest that the students who were able to establish personal connections to biology through reading and reflection were more likely to form an interest and understanding of biology as a whole over the course of the semester.

As key components of self-regulated learning, metacognition and goal orientation have been tied to improvements in academic achievement. Some research supports a bidirectional relationship between metacognition and goal orientation in which they promote each other as well as learning outcomes. We created a learning philosophy assignment (LP) to encourage students' consideration of their learning strategies and goals resulting in a record of students' metacognition. Research suggests that low-achieving students may have different metacognitive capabilities and learning goals and as such may be differentially impacted by the assignment. This paper considers the content of the LPs. Students were split into achievement quartiles to explore any patterns in metacognition or learning goals distinct to achievement level. Our content analysis confirms that the LP was successful in documenting metacognition and learning goals in all students. There were some differences related to achievement level.

We describe the development of a course to teach modeling and mathematical analysis skills to students of biology and to teach biology to students with strong backgrounds in mathematics, physics, or engineering. The two groups of students have different ways of learning material and often have strong negative feelings toward the area of knowledge that they find difficult. To give students a sense of mastery in each area, several complementary approaches are used in the course: 1) a "live" textbook that allows students to explore models and mathematical processes interactively; 2) benchmark problems providing key skills on which students make continuous progress; 3) assignment of students to teams of two throughout the semester; 4) regular one-on-one interactions with instructors throughout the semester; and 5) a term project in which students reconstruct, analyze, extend, and then write in detail about a recently published biological model. Based on student evaluations and comments, an attitude survey, and the quality of the students' term papers, the course has significantly increased the ability and willingness of biology students to use mathematical concepts and modeling tools to understand biological systems, and it has significantly enhanced engineering students' appreciation of biology.

Recent development in policy and learning theory encourages higher education institutions to send their students out of campus and into work placements. In this paper, we report on students' engagement with various aspects of knowing through practice in work placements. We employed focus group discussions to gather students' accounts of their knowing in the three higher education programmes: Teacher Education, Aqua Medicine, and Music Performance. The students' accounts of knowing were analysed as personal epistemologies. Thereby, we aimed to focus on how enacted practices in work develop students' appraisals of knowing and subjectivities. Three prominent epistemologies were present across all three student groups: professional judgment, professional practice, and professional identity. After the work placements, the students better understand how to enact their knowledge and what knowledge to pursue further. Based on these findings, we hold that there are key educational processes that arise in the interplay between students' situated enactment of practices, knowing, and personal epistemologies through work placements, and propose a conceptual model to frame students' learning in work placements.

Relating mathematics learned in the classroom to real situations increases student motivation and enhances learning. In this paper, we provide an example of a classroom application of calculus to physiology in two courses: "Differential Equations" and "Calculus I for Biology and Medicine." We designed and implemented a project that uses calculus to model the volume, flow, and pressure of air inside the lungs of a patient receiving positive pressure ventilation. After comparing mathematical models to a mechanically ventilated high-fidelity breathing simulator, students reported heightened interest in, and a greater appreciation for, the relevance of the calculus in both courses.

Student Engagement (SE) refers to the extent to which a student participates in academic and non-academic activities, invests in and commits to learning, belonging and identification with the educational institution. Despite the relevance of SE for students' success, a few valid and reliable instruments have been developed. This study presents the Italian validation of the University Student Engagement Inventory (USEI), which adopts both a 3 first-order conceptualization of the SE and a second-order construct (engagement). The paper reports the psychometric analyses (test-retest reliability, construct, convergent, discriminant validities, internal consistency) on a validation sample of 628 Italian university students from 2 areas of study (psychology and biology). Criterion validity was assessed in relation to students' drop-out intention, academic achievements, Grade Point Average (GPA) and motivation. Invariance analysis was performed for gender and area of studies. Results showed that the USEI presented a good test-retest reliability and factorial construct validity (both for the three-factor and one-factor models), it positively predicted students' academic motivation, GPA and academic achievements, and negatively intention to drop out. The results indicate that the USEI can produce valid data on SE in the Italian context and may have implications for assessing SE and implementing intervention programs.

This paper describes the structure and activities of READ (Reading Effectively Across the Disciplines), a pilot initiative to improve students' critical reading skills, disciplinary literacy and academic success. READ employs a multimodal design that consists of faculty training in disciplinary literacy instruction and curricular enhancement, development and implementation of active reading assignments and assessments, peer-led team learning, and the dissemination of discipline-specific teaching and learning resources on an Open Lab site to provide an interactive teaching and learning environment for students and faculty. Empirical evidence of the initial effectiveness of the pilot in three gateway courses in Biology, Electromechanical Engineering Technology, and Marketing showed improvement in student pass rates after implementation of reading strategies and instructional approaches that guide students through the reading process.

Service learning involves providing service to the community while requiring students to meet learning goals in a specific course. A service learning project was implemented in a general biology course at Rockhurst University to involve students in promoting scientific education in conjunction with community partner educators. Students were required to develop learning objectives, design and complete a community service exercise, and write reflection papers to assess the quality of their learning experience. Rockhurst students worked with high school or grade school students in the local community, providing learning experiences relating to course topics. Information gathered through reflection papers showed high student achievement and satisfaction in the following areas: 1) contributing to the learning of others, 2) contributing to their own learning, and 3) supporting the mission of the university.

This paper explores the effect of a paired lab course on students' course outcomes in nonmajors introductory biology at the University of Alaska Anchorage. We compare course completion and final grades for 10,793 students (3736 who simultaneously enrolled in the lab and 7057 who did not). Unconditionally, students who self-select into the lab are more likely to complete the course and to earn a higher grade than students who do not. However, when we condition on observable course, academic, and demographic characteristics, we find much of this difference in student performance outcomes is attributable to selection bias, rather than an effect of the lab itself. The data and discussion challenge the misconception that labs serve as recitations for lecture content, noting that the learning objectives of science labs should be more clearly articulated and assessed independent of lecture course outcomes.

STEM is about the integration of science, technology, engineering and mathematics. To teach STEM effectively, students need practical examples of subject integration. A good example is the use of an electron microscope in teaching physics and biology. An electron microscope is an instrument in which the operation depends on electromagnetism and quantum mechanics, in particular wave-particle duality. In teaching physics, an electron microscope can be used to measure the separation of repeated structures that give rise to interference phenomena. This paper describes the use a tabletop scanning electron microscope to teach physics and biology together through imaging butterfly wings. Students are able to identify structures with a spacing comparable to visible light on butterflies exhibiting structural colour and much larger spacing on wings without structural colour.

Block scheduling is the reallocation of a school day into longer class sessions to allow for more active teaching strategies and active engagement of students, in the effort to increase student performance. Various types of block scheduling exist. Traditional scheduling is when the school day is divided into six to eight sessions, with each session lasting from approximately 40 to 51 minutes. This paper seeks to find if test scores in a college biology course are significantly affected by high school scheduling type, gender, and the combined effects of both.

In this paper, it is aimed to investigate the persistence of misconceptions in the topic of the human blood circulatory system among students in different grade levels. For this reason, after discussions with biology educators, two tests consisting of open-ended questions were developed by the researcher and administered to students in four different grade levels. The first test was administered to 319 5th and 7th grade students in elementary school and the second one was administered to 400 1st and 4th year university students studying in the departments of elementary school teaching, science education and biology education. Data were analyzed using qualitative methods and a number of misconceptions were detected in different grade levels. According to the results of the study, the distributions of the percentages of students' misconceptions demonstrate a decreasing trend from elementary school students to university students without totally disappearing. The reason of this situation might be the persistence of misconceptions that are difficult to overcome. Due to their functionality, students continue to possess certain misconceptions. Hence, this characteristic of misconceptions should be considered while planning teaching activities in teacher education programs. (Contains 3 tables and 6 figures.)

In life sciences, the internet is an indispensable medium for research, but has not yet realized its full potential for teaching. The concept of e-learning has been developed over the past decades for undergraduate, graduate and postgraduate programs. We set up an e-learning lecture on cancer biology and pharmacology that was first offered in 2003 to students of Molecular Biotechnology at the University of Heidelberg and to students of Pharmacy at the University of Mainz, Germany. The present paper recapitulates the first decade of experiences with this e-learning lecture from both the students' and the teachers' perspectives. A total of 317 students during the past 10 years participated in a survey. In general, the students enjoyed the possibilities that self-controlled learning offers. E-learning interested them as a novel educational method. They felt quite comfortable listening to the material despite the interdisciplinary nature of the lectures, which included molecular biological, pharmacological and medical aspects of cancer biology and pharmacology. This lecture was the first e-learning experience for the majority of students, and their impressions were generally positive. The students not only indicated that they would like to continue with e-learning, but also would recommend e-learning to other students. Remarkably, the majority of students would like to see more e-learning offered in their present curricula. They indicated interest in mixed forms of traditional learning and e-learning ("blended learning"), although it is recognized that face-to-face contact between teachers and students is critical. Overall, many students would consider e-learning for further and continuing education after graduation.

Web 2.0 technologies, such as social networks, wikis, blogs, and virtual worlds provide a platform for collaborative working, facilitating sharing of resources and joint document production. They can act as a stimulus to promote active learning and provide an engaging and interactive environment for students, and as such align with the philosophy of Problem-based Learning. Furthermore, Web 2.0 technologies can provide the tutor or facilitator with an opportunity to scaffold and asses the PBL process. However, whilst it is recognised that technology has an important role in enhancing each step of a PBL exercise, academic staff can be reluctant to use it. This paper provides some illustrative examples of the technologies that have been used to enhance, scaffold and assess PBL and their evaluation by distance learning and on-campus students at the University of Ulster. The benefits and limitations of using technology for both staff and students to support PBL are discussed.

This paper investigates the magnitude of difference of academic achievement scores by language of instruction of prior education and the magnitude of interaction between language of instruction of prior education and students' preferred learning trait on academic performance of a group of international students in two teaching and learning practices. The magnitude of difference and magnitude of interaction were determined by using Cohen's "d" with Hedges "g" correction. Coe's spread sheet was used for the analysis. The study showed that the magnitude of difference of academic achievement score was found to be "very small" on Traditional method of Teaching and Learning (TTL) and small on Problem-Based method of Learning (PBL). However, the magnitude of interaction between language of instruction of prior education and learning traits varied from very small to large. It is a challenging task to accommodate international students from different language background and optimize the whole learning process in an English speaking teaching and learning environment.

Bioinformatics is a relatively new interdisciplinary field that integrates computer science, mathematics, biology, and information technology to manage, analyze, and understand biological, biochemical and biophysical information. We present our experience in teaching an interdisciplinary course, Introduction to Bioinformatics, which was developed and taught by an interdisciplinary team of computer science and biology faculty. To integrate the "Ethics, Computing, and Genomics" component into the course curriculum, collaboration with an English faculty member was established. The course was designed as an upper-level elective for computer information systems and computer science majors and was open as a science elective for all science majors and for chemical engineering majors. We discuss the course curriculum, and a way to integrate the Python programming language in the UNIX environment will be presented. The integration of bioinformatics algorithms into the course curriculum will be emphasized.

Our interpretative study that was carried out in a science and engineering oriented university examined the ways students in an introductory biology course perceived their learning in the course that was substantially changed to allow student-centered learning. The instructional change was framed by the view of learning as a sociocultural activity as well as a cognitive process that can take place face-to-face or through online interaction. Most of the lectures were substituted with individual learning and project-based, small-group learning that lasted one month. Data were collected through interviews with students and instructors, and through observations. In the paper, we show evidence for deep learning that was associated by the students and the instructors with short-term, meaningful activities in a setting that included collaborative peer learning; and replacing most lectures by small group learning that ended in a mini-conference. Deep learning was evidenced by the ways students reflected on how they organised and applied knowledge using deep learning strategies.

Science courses with hands-on investigative labs are a typical part of the general education requirements at virtually all colleges and universities. In these courses, labs that satisfy a curricular requirement for "lab experience" are important because they provide the essence of the scientific experience--that is, they give students hands-on experience with designing experiments, handling and studying organisms, learning laboratory skills, analyzing data, and communicating results. To help ensure that students obtain this experience, most introductory courses have attendance requirements for lab. Although there have been many studies of students' overall performances in introductory science courses, there have been virtually no studies of students' performances in the laboratory portions of introductory science courses. This paper reports a study of students' academic engagement in labs of an introductory biology course. Class attendance is the leading indicator of academic engagement (e.g., students' course-related effort and activities) because it requires a consistent and ongoing effort that is directly related to students' academic success. This study was conducted in a traditional introductory biology course at the Twin Cities campus of the University of Minnesota. The study included 1674 students enrolled during eight semesters from 2003-2006. The lab grade, lab attendance, and course grade of all students were monitored in this study. The results indicate that data-based changes in attendance policies can improve students' academic behaviors. The increased rate of lab attendance associated with a new policy correlated with a significant improvement in students' laboratory grades. The results support the claim that increased levels of course-engagement increase students' grades in labs of introductory science courses. Data presented in this study show that lab attendance, like lecture attendance, is also a strong predictor of students' academic performances in introductory science courses; students who miss increased numbers of labs earn progressively lower grades, regardless of the course policy about lab attendance.

Effective pedagogical strategies are needed to improve statistical literacy within health sciences education. This paper describes the design, implementation, and evaluation of a highly interactive two-week biostatistics short course using the flipped classroom model in the United States. The course was required for all students at the start of a doctoral degree program with the goal of standardizing student preparation, contextualizing biostatistics to healthcare, and identifying students needing additional help. We focused on basic concepts and methods, their application to healthcare, selection of statistical procedures, and results interpretation. Data indicate that students were actively engaged, perceived the course as useful, and experienced learning gains. After the course, students indicated that they better understood the relevance and applicability of biostatistics and were motivated to learn more.

Conditions producing stress are present in all colleges and universities. In this paper we report on an investigation utilizing heart rate as an indicator of stress in students when participating in activities encountered in a college classroom or laboratory. The activities included presenting an oral report, taking an exam, and participating in a competitive laboratory exercise. Increased change in heart rate was observed in students participating in these activities. These heart rate responses provide some insight into the factors in the classroom, which produce stress in our students. (Contains 3 figures.)

GRE verbal and quantitative scores and undergraduate grade point average were evaluated as predictors of multiple measures of long-term graduate school success. The measures of success were cumulative graduate grade point average and faculty ratings on three student characteristics: mastery of the discipline, professional productivity, and communication skill. Seven graduate institutions and 21 graduate departments in biology, chemistry, education, English, and psychology collaborated in order to identify measures of valued outcomes, develop reports useful to individual departments and graduate schools, and initiate a database for future studies. Results are reported for all departments combined and by discipline and, where sample sizes permitted, for master?s and doctoral degree students, men and women, U.S. citizens and noncitizens, domestic ethnic groups, and test takers who took the GRE computer-based test and those who took the paper-and-pencil version of the test. The results indicate that the combination of GRE scores and undergraduate grade point average strongly predicts cumulative graduate grade point average and faculty ratings. These results hold in each discipline and appear to hold in the small subgroups.

The authors tested the predictions of a game theory model of plagiarism, using a test population of student papers submitted to an online plagiarism detection program, over five semesters in a non-majors biology course with multiple sections and high enrollment. Consistent with the model, as the probability of detection and the penalty if caught increased, plagiarism rates dropped, although the latter had a smaller effect. The percentage of plagiarized papers decreased from almost 30% to less than 6% between semesters, as more students became aware that the entire course utilizes a plagiarism detection program and penalizes students who are caught plagiarizing. (Contains 1 table and 5 figures.)

This paper presents research findings related to the "Dynamic Enhanced Evaluation of Problem Solving (DEEP)" (Spector & Koszalka, 2004) methodology for assessing how participants conceptualize ill-defined problems in biology using annotated concept maps. The methodology engages highly experienced (expert) and less experienced (novice) participants in creating annotated problem representations. This exploratory study addressed the lack of assessment methods to assess learning progress and relative level of expertise in complex, dynamic domains. This paper addresses (1) differences between experts and novices, (2) learning in complex domains, and (3) the rational for using annotated concept maps to assess learning in complex domains. Findings suggest that there are similarities in how experts think about ill-defined problems and these similarities are different than novices. These findings thus suggest that this methodology is useful in distinguishing relative levels of expertise in conceptualization of complex and challenging problems in a biology context.

The phenomenon of industrial melanism (IM) became widely acknowledged as a well-documented example of natural selection largely as a result of H.B.D. Kettlewell's pioneering research on the subject in the early 1950s. It was quickly picked up by American biology textbooks starting in the early 1960s and became ubiquitous throughout the 1970s, 1980s and 1990s. While recent research on the phenomenon broadly supports Kettlewell's explanation of IM in the peppered moth, which in turn has strengthened this example of natural selection, textbook IM entries have actually declined in recent years in favor of other examples. In a previous paper, we drew attention to the pivotal role visual aspects played in the introduction of IM into (and its subsequent removal from) textbook accounts. The present article continues this investigation by analyzing textual passages on industrial melanism within a stratified random sample of textbooks from the 1960s to the 2000s. The fact that this example of natural selection was included by multiple publishers independently, in a short period of time, makes it uniquely qualified for a textbook study of this kind. The purpose of the present project was to determine whether these textbooks contain what has come to be known as the standard peppered moth story. Three complete series were also inspected for change across time. Our analysis focused on (1) the amount of text devoted to industrial melanism; (2) what specific science content elements were present; and (3) what, if any, nature of science (NOS) aspects were included. The study documents an increase in the amount of text devoted to industrial melanism over the decades. In spite of this increase, only modest changes in science content and NOS aspects were found.

Reviews of the state of biology fieldwork in UK schools and universities at the beginning of the twenty-first century (Barker, Slingsby, and Tilling 2002; Smith 2004) were not entirely pessimistic; rather they suggested ways forward that might lead to an increase in fieldwork. Whether their hopes have been realised has, perhaps, been revealed by later studies. In 2006, the National Foundation for Educational Research comprehensively surveyed the extent of learning outside the classroom in English schools (O'Donnell, Morris and Wilson 2006). This survey included all kinds of fieldwork as well as that in biology and it concluded that, although many commentators had argued that there was a decline in fieldwork, there was little evidence in support of decline. Schools and local authorities considered that provision had increased or remained largely the same over the previous five years. Field work by primary schools on school sites was commonly reported as increasing. Less encouraging, however, are the findings of a metastudy by Lock (2010) of publications between 1963 and 2009, although only three out of 13 of these reported surveys were done after 2000, which addressed biology fieldwork provision for 16-19 year olds in UK schools and colleges. This study suggested that according to several criteria (time in the field, the number of teachers taking fieldwork, teacher perception of change and the amount of residential fieldwork) the extent of fieldwork had declined. Other criteria (the number and type of habitats visited) showed no clear evidence of change. The current status of fieldwork in UK universities, not withstanding the negative comment that has been reported in this article, appears to be buoyant. Maw, Mauchline, and Park (2011) surveyed academics from 27 institutions by questionnaire in 2010 and found no evidence of a decrease in biological fieldwork over the previous five years. Furthermore, when staff from 27 universities were interviewed by Skype or telephone in 2012 (Mauchline, Peacock, and Park 2013) there was no evidence of decline in fieldwork over the previous five years; fieldwork was greatly valued and a future increase was predicted in some institutions. The funding of fieldwork in UK universities has been anomalous in that students have sometimes been charged for fieldwork costs whereas expensive consumables used in laboratory classes have been provided without extra charge. Mauchline, Peacock, and Park (2013) suggested that the introduction of full-cost fees from 2012 has led to the deletion of extra charges for fieldwork; they suggest that this may boost fieldwork. Other suggested positive factors are that the promise of fieldwork enhances student recruitment, that fieldwork skills enhance employability and that students enjoy doing fieldwork. This is supported by the authors'experience with students at Hull University; they found that students valued fieldwork because of its leading to outdoor career opportunities and students largely enjoyed the fieldwork experience (Goulder, Scott, and Scott 2013; Scott et al. 2012). Here the authors posit that all in all, although there is clearly much difference of opinion, they are unconvinced that biological fieldwork and identification skills are currently at significant risk in UK universities; they also believe that fieldwork in schools has the potential for a positive future.

Purpose: This paper aims to discuss the methods that were used to do egalitarian research with ten Historically Black Colleges and Universities (HBCUs). Rather than doing research "on" these institutions, the authors worked with them to understand their successes and build upon their capacity in the science, technology, engineering and math (STEM) areas. Through this process, the authors aimed to bring exposure and interest to the practices that HBCUs use to increase and nurture success in African American students--practices that are rarely used in mainstream STEM programs and, in fact, run counter to well-established practices across STEM. The goal is to challenge traditional methods for pursuing STEM education research as the authors offer alternative methods the uplift and empower HBCUs. Design/methodology/approach: The authors used the constant comparative method in developing, testing, and writing-up the HBCU success stories. The constant comparative method collects data in a systematic way by engaging in ongoing exploration and verification of findings with key stakeholders (in this case, the teachers, students and staff at the HBCUs). Across the ten HBCUs in the sample, at least one success story or model at each institution was identified; in some instances, there were more. Findings: The research project had several implications for the social and economic health of society. First, supporting the work of HBCUs contributes to the diversification of the STEM fields and addresses the severe drought in the STEM workforce. It is without doubt that a diverse workforce--the unique perspectives and backgrounds of each individual--has a positive and significant influence on progress and innovation in any field. Despite increasingly growing minority communities across the country, many Blacks continue to face roadblocks that impede their opportunities and abilities in the K-20 pipeline and STEM education, specifically. Because HBCUs have a long history and record of tearing down those roadblocks and contributing Black students to the STEM workforce, they are prime and optimal sites for long-term investment. Second, improving the abilities of HBCUs to support student success in STEM also increases the likelihood of greater STEM minority teachers and faculty. A significant factor in the success of minority students in STEM is the opportunity to be taught and mentored by faculty members that look like them and/or deeply understand their personal background and struggles. For many Black students, the presence of a Black science professor can improve and retain student interest and aspiration in STEM. But with so few Black STEM faculty members, many students can easily fall through the cracks. Third, aside from the nation's security and health, supporting HBCUs' work in STEM student achievement represents immeasurable benefits for the individual and his/her family for many generations to come (i.e. society overall). Occupations in STEM are plentiful and fruitful for those who achieve the required credentials. Increasing opportunities for Black students to pursue these STEM careers can establish a path toward upward social mobility. The realization of these benefits is contingent upon the investment in early achievement in STEM courses. Research limitations/implications: Several research based outcomes are scheduled to result from this project, including a major policy report on HBCUs and their approaches to STEM education (co-constructed with the HBCU representatives); several peer reviewed articles (authored by us as well as the HBCU representatives); a national convening (showcasing both the best practices and the results of the HBCUs' funded capacity building projects with the HBCU representatives as the primary speakers rather than us); a website featuring the work of the 10 HBCUs, active use of social media to disseminate the findings of the project; several op-eds written for a general audience and co-authored with HBCU representatives; and an authored book published by a university press. Practical implications: Best practices gleaned from this project are being shared in a scholarly manner, but they will be shared in ways that are accessible to practitioners, including presidents, faculty, academic advisors, student success staff and other HBCU practitioners. In addition, best practices will be shared with majority colleges and universities to strengthen and improve practices more broadly in STEM. The authors are working with organizations such as the Association of American Universities, Association of Public Land Grant Universities and the American Association of Colleges and Universities to showcase the work of HBCUs and disseminate information. Social implications: Conducting research projects in which the research inquiry is co-constructed and the resulting research products are also co-constructed and even co-authored is an empowering and collaborative way to work across institutional types. More importantly, this approach brings attention to those researchers and teachers at HBCUs that are doing the day-to-day work with students, training them to be scientists, doctors and professors. Too often, only those conducting studies on STEM are credited with "discovering" success models for student learning. The authors think that those who have created these models and use them should be recognized and included in the research and dissemination process, and the authors encourage others to think more broadly and openly about collaborative research that engages the voices of HBCU researchers and students. Originality/value: This project also has much to teach others about collaborating through research. First, collaborating when conducting research related to STEM is essential, as it encourages collaboration within STEM and among STEM researchers. HBCU researchers that were a part of our project--biologists, physicist and chemists--were encouraged to work across disciplinary lines and together to understand their own STEM education practices more fully.

The understanding of core concepts and processes of science in solving problems is important to successful learning in biology. We have designed and developed a Web-based, self-directed tutorial program, "SOLVEIT," that provides various scaffolds (e.g., prompts, expert models, visual guidance) to help college students enhance their skills and abilities in solving problems in science. An initial version of "SOLVEIT" was used in this study. This paper details the features of "SOLVEIT" that are contextualized within the biological domains of evolution and ecology. A qualitative case study was conducted to evaluate the usability of the program. Selected students were recruited from an introductory biology course at a large public university in the south-eastern United States. Data for this study were collected through the "SOLVEIT" database and semi-structured interviews. The findings of this study demonstrate the potential of the program for improving students' problem solving in biology. Suggestions for the use of "SOLVEIT" and its further improvement and development are discussed, along with suggestions for future research. This study also provides more general guidance for researchers and practitioners who are interested in the design, development and evaluation of Web-based tutorial programs in science education.

Darwin's theory of evolution is explicitly competitive, yet co-operation between individuals is a common phenomenon. The Prisoner's Dilemma model is central to the teaching of the evolution of co-operation. The best-known explorations of the Prisoner's Dilemma are the tournaments run by Robert Axelrod in the 1980s. Aimed at students of biological or behavioural science (post-compulsory education), this paper proposes a simplified, non-computer-based version of Axelrod's Tournament which allows students to explore the Prisoner's Dilemma using different behavioural strategies. In this classroom exercise, students become the players in a repeated Prisoner's Dilemma situation. They investigate the outcomes of different strategies of play using a simple scoring system. After each generation of play, students discuss the evolutionary success of the strategies--strategies that score poorly are discarded and replaced with those that score well. Four generations of play are suggested, after which "Tit for Tat" will have become the dominant strategy in the population, as it did during Axelrod's original tournaments. Students gain a basic understanding of the evolution of co-operation, and the associated written report encourages them to investigate the process in more depth.

In their 2012 report, the President's Council of Advisors on Science and Technology advocated "replacing standard science laboratory courses with discovery-based research courses"--a challenging proposition that presents practical and pedagogical difficulties. In this paper, we describe our collective experiences working with the Genomics Education Partnership, a nationwide faculty consortium that aims to provide undergraduates with a research experience in genomics through a scheduled course (a classroom-based undergraduate research experience, or CURE). We examine the common barriers encountered in implementing a CURE, program elements of most value to faculty, ways in which a shared core support system can help, and the incentives for and rewards of establishing a CURE on our diverse campuses. While some of the barriers and rewards are specific to a research project utilizing a genomics approach, other lessons learned should be broadly applicable. We find that a central system that supports a shared investigation can mitigate some shortfalls in campus infrastructure (such as time for new curriculum development, availability of IT services) and provides collegial support for change. Our findings should be useful for designing similar supportive programs to facilitate change in the way we teach science for undergraduates.

Students express widespread dissatisfaction with academic feedback. Teaching staff perceive a frequent lack of student engagement with written feedback, much of which goes uncollected or unread. Published evidence shows that audio feedback is highly acceptable to students but is underused. This paper explores methods to produce and deliver audio feedback to a range of students engaged in a variety of academic tasks with the aim of maximising student engagement while working towards a framework which could increase the use of audio feedback by teaching staff.

Understanding fear, its causes, and its impact on students can be important for educators who seek ways to help students manage their fears. This paper explores common types of student fears such as performance-based anxiety, fear of failure, fear of being laughed at, and cultural components of fear that impact learning. The cognitive, emotional, and physiological components of fear are also investigated, including its role in memory deficits and key functions of the central nervous system that may be short-circuited when students are overwhelmed by feelings of fear. Specific strategies for educators are provided to help students manage fear-based behaviors and achieve emotional balance and academic success in the classroom. These strategies include educating oneself and students about fear, creating a nurturing environment for students, taking advantage of campus resources, being proactive about communicating with students outside of the classroom, and incorporating active learning strategies.

This paper reports on teachers' use of concept mapping as an alternative assessment strategy in advanced level biology classes and its effects on students' cognitive skills on selected biology concepts. Using a mixed methods approach, the study employed a pre-test/post-test quasi-experimental design involving 156 students and 8 teachers from intact classes. A researcher-constructed Biology Cognitive Skills Test was used to collect the quantitative data. Qualitative data were collected through interviews and students' personal documents. The data showed that the participants utilized concept mapping in various ways and they described positive experiences while being engaged in its use. The main challenge cited by teachers was the limited time available for more consistent use. The results showed that the use of concept mapping in advanced level biology can lead to learning gains that exceed those achieved in classes where mainly traditional methods are used. The students in the concept mapping experimental groups performed significantly better than their peers in the control group on both the lower-order (F[subscript (1)]?=?21.508; p?

This is a corpus-based study of a key aspect of academic writing in one discipline (biology) by final-year undergraduates and first-, second-, and third-year graduate students. The papers come from the Michigan Corpus of Upper-level Student Papers, a freely available electronic database. The principal aim of the study is to examine the extent of variation in citation practice in the biology subcorpus. To that end, it explores citation practices from a number of perspectives, including the distribution of integral versus parenthetical citations, the choice of reporting verbs, the effect of citing system, and the occurrence of selected features such as the use of citees’ first names. Results show little difference between the undergraduate and graduate papers, some effect of the citing system, and a somewhat richer intertextuality in the “evolutionary” as opposed to the “molecular” biology papers. Overall, this is an impressive body of student work from the viewpoint of textual variation in citation practice, but it should be remembered that the corpus consists of only “A” papers from a flagship research university.

Mathematical models and mathematical modeling play different roles in the different areas and problems in which they are used. The function and status of mathematical modeling and models in the different areas depend on the scientific practice as well as the underlying philosophical and theoretical position held by the modeler(s) and the practitioners in the extra-mathematical domain. For students to experience the significance of different scientific practices and cultures for the function and status of mathematical modeling in other sciences, students need to be placed in didactical situations where such differences are exposed and made into explicit objects of their reflections. It can be difficult to create such situations in the teaching of contemporary science in which modeling is part of the culture. In this paper we show how history can serve as a means for students to be engaged in situations in which they can experience and be challenged to reflect upon and criticize, the use of modeling and the significance of the context for the function and status of modeling and models in scientific practices. We present Nicolas Rashevsky's model of cell division from the 1930s together with a discussion of disagreement between him and some biologists as one such episode from the past. We illustrate how a group of science students at Roskilde University, through their work with this historical case, experienced that different scientific cultures have different opinions of the value of a model as an instrument for gaining scientific knowledge; that the explanatory power of a model is linked not only to the context of its use, but also to the underlying philosophical and theoretical position held by the modeler(s) and the scientists discussing the model and its use. The episode's potential to challenge students to reflect upon and criticize the modeling process and the function of models in an extra mathematical domain is discussed with respect to the notions of internal and external reflections.

Students' epistemological views about biology--their ideas about what "counts" as learning and understanding biology--play a role in how they approach their courses and respond to reforms. As introductory biology courses incorporate more physics and quantitative reasoning, student attitudes about the role of equations in biology become especially relevant. However, as documented in research in physics education, students' epistemologies are not always stable and fixed entities; they can be dynamic and context-dependent. In this paper, we examine an interview with an introductory student in which she discusses the use of equations in her reformed biology course. In one part of the interview, she expresses what sounds like an entrenched negative stance toward the role equations can play in understanding biology. However, later in the interview, when discussing a different biology topic, she takes a more positive stance toward the value of equations. These results highlight how a given student can have diverse ways of thinking about the value of bringing physics and math into biology. By highlighting how attitudes can shift in response to different tasks, instructional environments, and contextual cues, we emphasize the need to attend to these factors, rather than treating students' beliefs as fixed and stable.
