Background Objectives Methods Results and conclusions Major takeaways With the recent pivot to online instruction and/or to mixed online/face‐to‐face (i.e., hybrid) models of teaching necessitated by the novel coronavirus pandemic, the uses of technology to support instruction would seem to have great importance. Whereas effective integration of technology in mathematics classrooms requires recognition of students’ needs and instructional goals that technology could fulfill, very few comprehensive meta‐analytical studies have focused on the roles of instructional technology in support of specific learning goals.In this meta‐analysis, we investigated and reviewed the roles and affordances of technology in mathematics instruction and its effects on students' mathematics achievement.Cross‐searching multiple bibliographic databases generated a total of 3276 potentially relevant full‐text studies. After applying a series of inclusion/exclusion criteria, we kept 77 studies with 151 effect sizes. Two researchers then coded for seven sets of study features and student characteristics: technology roles, publication‐related features (years and resources), research design, sample size, grade levels, duration of interventions, and types of the testing instruments. The coding achieved acceptable levels of inter‐rater reliabilities. Since effect sizes varied across studies and student populations, random‐effects models were used for overall effect estimates and moderator analyses.Overall, this meta‐analysis revealed a small, positive, and statistically significant effect of technology on students' mathematics achievement with an average Hedges' s g (ḡ) of 0.23. The largest significant moderator effects were found when technology was used to design and support collaborative and communicative environments (ḡ = 0.49);the next‐largest moderator effects were found when using technology as supports for problem‐solving (ḡ = 0.39), followed by the roles of as supports for conceptual development (ḡ = 0.31) and as adaptive mathematics practices (ḡ = 0.28). This study also found that the effects of technology were differentiated as a function of publication resources, research design, duration of intervention, and the testing instrument.Focusing on the roles and functions of technology, this study can contribute to guide potential synthetical studies as well as the future design of educational technology. In particular, technology is used effectively when it is used (a) to create and design a collaborative and communicative learning environment where students have chances to collaborate and interact with each other and (b) as supports for mathematics problem‐solving and for mathematics conceptual development. On the other hand, technology is less effective when it is used for monitoring and assessing students' learning processes without follow‐up instructions.The findings suggested that technology intervention lasting for a shorter time is the better choice. When technology is used for longer periods of instruction, maintaining its novelty and students’ curiosity should be considered. This study also suggested that incorporating computer‐adaptive testing in technology‐based intervention programs is more likely to detect technology effects as adaptive testing could continuously adjust to the abilities of individual students.

Noticing and interpreting classroom events (professional vision) is an important element of preservice teachers' (PSTs) interpersonal competence. This paper presents a mixed-method study about a classroom simulation using 360-degree videos combined with theoretical lectures in teacher education, intended to improve PSTs' interpretations of noticed events. Furthermore, this study examined how PSTs evaluate technological and educational affordances of 360-degree videos. Results indicate that participating PSTs improved in noticing classroom events and in applying a more theory-based terminology to describe these events. PSTs perceived observing other teachers teach as an educational affordance for mastering theory and for developing insights about interpersonal teacher behaviour. Concerning technological affordances, mainly physical discomforts and technical hindrances, was reported by PSTs. The results of this study imply that 360-degree videos can be useful for teacher education to improve PSTs' interpretation of noticed events.

This study investigated the role of content knowledge in conversations of kindergarten teachers during collaborative curriculum design of learning material for technology-enhanced learning. Two teams of teachers received support from an early literacy expert during these design activities. Resulting conversations were analyzed on technological pedagogical content knowledge, explicated reasoning, and the contributions of expert support. This study found that in explicating content knowledge and pedagogical content knowledge, teachers set goals and deliberated on strategies and activities that would be most appropriate for their students. Technological content knowledge and technological pedagogical content knowledge were explicated most during deliberations on practical concerns; these mainly revolved around optimizing the affordances of technology. This study contributes to understanding and supporting the pedagogical design capacity of teachers.

The purpose of this single-case study was to explore the lived experiences of a grade 6 teacher and students who used tablets as part of their classroom instruction. Malone and Lepper's taxonomy of intrinsic motivations for learning is used as a framework for examining whether and how this particular theory of motivation applies equally well for mobile learning. This study reports on the grade 6 teacher's and students' perceptions regarding the motivational affordances of using these mobile devices for learning. The findings are consistent with those of Malone and Lepper that motivation can be enhanced through challenge, curiosity, control, recognition, competition and cooperation. This model is helpful in informing our understanding of the motivating features of using mobile devices for learning and how mobile technologies can be used to enhance learners' motivation.

With the increased affordances of synchronous communication tools, more opportunities for online learning to resemble face-to-face settings have recently become available. However, synchronous communication does not afford as much time for reflection as asynchronous communication. Therefore, a combination of synchronous and asynchronous communication in e-learning would seem desirable to optimally support learner engagement and the quality of student learning. It is still an open question though, how to best design online learning with a blend of synchronous and asynchronous communication opportunities over time. Few studies have investigated the relationship between learners' actual use of synchronous and asynchronous communication over time. Therefore, this study addressed that relationship in an online course (N = 110), taking into account student motivation, and employing a dynamic inter-temporal perspective. In line with our assumptions, we found some support for the expected association between autonomous motivation and engagement in asynchronous and synchronous communication, be it restricted primarily to the first course period. Also, positive relations between engagement in synchronous and asynchronous communication were found, with the strongest influence from using asynchronous to synchronous communication. This study adds to the knowledge base needed to develop guidelines on how synchronous communication can be combined with asynchronous learning.

This paper describes the design of a mathematical microworld to tackle the persistent difficulties that secondary school students have with the idea of algebraic generalization, which is a key stumbling block in secondary-school mathematics classrooms. Our focus is to characterize algebraic ways of thinking and to design both affordances of the system as well as suitable tasks and pedagogies that provide a substrate of activity and experience for the teaching and learning of algebraic generalizations. Using as reference illustrative cases of 12 to 13-year-old students' interaction with the microworld, we demonstrate the strong interplay between epistemology and the design of the microworld and draw conclusions regarding its potential to support the development of algebraic ways of thinking.

'Ensemble' is an interdisciplinary research and development project exploring the potential role of emerging Semantic Web technologies in case-based learning across learning environments in higher education. Empirical findings have challenged the claim that cases 'bring reality into the classroom' and that this, in turn, might provide the basis for an understanding of the role of Semantic Web technologies in case-based learning environments. We describe how the work of authors including Baudrillard and Deleuze has provided an alternative framework for understanding the relationships between cases and the realities with which they are purportedly associated. We discuss how the idea of the 'simulacrum' has influenced our understanding of learning environments, has informed design and development practices, and has led to a shift in our understandings of the potential affordances of Semantic Web technologies in educational settings.

This paper presents the findings of a research project in which we transformed a primary (grade) 3 science curriculum for delivery via mobile technologies, and a teacher enacted the lessons over the 2009 academic year in a class in a primary school in Singapore. The students had a total of 21 weeks of the mobilized lessons in science, which were co-designed by teachers and researchers by tapping into the affordances of mobile technologies for supporting inquiry learning in and outside of class. We examine the learning effectiveness of the enacted mobilized science curriculum. The results show that among the six mixed-ability classes in primary (grade) 3 in the school, the experimental class performed better than other classes as measured by traditional assessments in the science subject. With mobilized lessons, students were found to learn science in personal, deep and engaging ways as well as developed positive attitudes towards mobile learning.

In this paper, we devise a diagrammatic conceptualization to describe and represent the complex interplay of a teacher’s knowledge (K), goals (G) and beliefs (B) in leveraging technology effectively in the classroom. The degree of coherency between the KGB region and the affordances of the technology serves as an indicator of the teachers’ developmental progression through the initiation, implementation and maturation phases of using technology in the classroom. In our study, two teachers with differing knowledge, goals and beliefs are studied as they integrated GroupScribbles technology in their classroom lessons over a period of 1 year. Our findings reveal that the transition between the teacher’s developmental states (as indicated by coherency diagrams) is nonlinear, and thus the importance of ensuring high coherency right at the initiation stage. Support for the teacher from other teachers and researchers remains an important factor in developing the teacher’s competency to leverage the technology successfully. The stability of the KGB region further ensures smooth progression of the teacher’s effective integration of technology in the classroom.

In the Singapore primary school Mathematics curriculum, students are taught the model method that uses bar diagrams to visualize the problem structure in a given word problem. When these students progress to secondary school, they learn the algebraic way of solving word problems. Studies (e.g. Ng et al.) have shown that poor bridging of students from the use of bar diagrams to the use of letter-symbolic algebraic methods can hinder their learning of algebra. We design a software tool 'ALGEBAR' to scaffold the learning of the algebraic process, especially the formulation of equations to support a pedagogy that seeks to help students transit from bar diagrams to algebraic methods. In this paper, we report a cycle of evaluation of the intervention pedagogy by examining a class that uses the software tool as part of a holistic intervention package. This evaluation is in the context of an overall design research approach that sought to address complex problems in real classroom contexts in collaboration with practitioners and to integrate design principles with technological affordances to render plausible solutions. Our findings show that the software tool can be an important enabler of the bridging process.

All communication is inherently multimodal, and understandings of science need to be multidimensional. The interactive whiteboard offers a range of potential benefits to the primary science classroom in terms of relative ease of integration of a number of presentational and ICT functions, which, taken together, offers new opportunities for fostering multifaceted pedagogic strategies. In this case study, we examine in detail how a teacher pursues two themes across four science lessons. We examine how the teacher creates continuity in her students’ learning experiences through taking up some of the affordances of the IWB in order to represent scientific phenomena and engage children in activities to consolidate their understandings. Support is offered for the notion that while pedagogic goals and strategies must determine the selection of tools, rather than the ‘tail wagging the dog’ as in technology-focussed hyperbole, planned use of the interactive whiteboard, conceptualized as a ‘heterogeneous mediational tool kit’ (Wertsch 1991), can be effectively integrated into teaching practice.

The issues raised by the design and development of technologies to enhance learning has led to a demand for an appropriate language and form of conceptualisation. However we are insufficiently familiar with the way in which different types of mediated tool use occur, to develop the theoretical models needed for the development of this language and form of conceptualisation. In its absence a somewhat eclectic variety of concepts and research, such as the concept of affordance, are recruited in accounts of learning with new technologies. In looking briefly at the relevant area in philosophy this paper will consider whether or not the use of concepts such as affordance give adequate weight to social practice, meaning and knowledge in the design of educational technology. A fruitful source for work in this field which has not been sufficiently exploited is philosophy, particularly recent work in epistemology.

Experiential learning is the process of creating knowledge through the transformation of experience and has been adopted in an increasing number of areas. This paper investigates the possibility of technological support for experiential learning. A learning activity flow (or script) and a mobile technology system were designed to facilitate students in experiential learning. An experiment was conducted on two fifth-grade classes at an elementary school, one class using personal digital assistants (PDAs) and the other working without them. The results indicate that mobile technologies are effective in improving knowledge creation during experiential learning. The interplay between the mobile technology affordances and the proposed learning flow for experiential learning is thoroughly discussed.

educational computing refers to a scenario where every student in a group or class uses a computing device equipped with wireless communication capability to conduct a learning task. This paper, drawing from design experiences with our digital classroom environment series and other studies, attempts to describe a few valuable 1:1 design perspectives for educational computing inside the classroom. We try to describe the major components of the 1:1 digital classroom environment and classify the most important component, student devices, according to a set of features. Furthermore, based on the notion of computing af- fordance, a set of communication affordances are described. This set underpins three basic educational activities, namely: teacher-directed instruction, small group learning and in- dividual learning. Finally, scenarios are exemplified for a few typical educational computing devices. This study concludes with a discussion of short- and long-term research possibi- lities.

This paper addresses a fundamental dilemma in the design of intelligent language learning environments: the more freedom a system offers to learners in the use of the target language, the more unwieldy the data is which the learners produce and the less able the system is to support inferences about learners from that data. It is shown how in a platform where learners and teachers interact, the teachers' feedback which is archived in the system and indexed to the learners' target language production can constitute affordances that support a process of bootstrapping from raw language output to potential insights into the learners' interlanguage and gaps in their grasp of the target language. The approach is illustrated with three types of learner errors uncovered in the corpus of learner English through this bootstrapping heuristic.

Evaluative studies of CMC can produce misleading or even contradictory results due to an (understandable) focus on how the characteristics of the medium affect usage, ignoring the dialectic between technology and culture, of mutual adaptation over time. CMC exchanges in Higher Education take place within a broad teaching and learning system, of which most participants already have extensive experience. This system provides the context within which participants make sense of, and adapt to, the use of on-line communications. Thus interpretations of the processes shaping exchanges and their outcomes have to take into account: who participants see themselves as communicating with and why, how this serves longer-term learning goals, and what past experience of engaging with both task and audience they have had; what kinds of exchange are facilitated, both by the medium itself and how the task is organised, and how such affordances are honed over time; and also, how these interactions impact on other aspects of teaching and on learning outcomes.
