In solving mathematics problems in collaboration, students encounter a range of mathematical and social struggles. As teachers cannot possibly respond to every such struggle, they may need to respond to those with which students require most support. Yet, little is known about students' success in overcoming the various types of struggle they…

Physical education is a course that integrates knowledge of sports with skill drilling. Augmented Reality (AR)-assisted instruction has infrequently been applied in sport skill drilling. Video-assisted instruction has frequently applied to physical sports; however, it neither involves interactive practice nor embodies both textbook learning and…

Background: Video lectures which include the teachers' presence have become increasingly common. As teacher enthusiasm is a nonverbal cue in video lectures, more and more studies are focusing on this topic. However, little research has been carried out on the interactions between teacher enthusiasm and prior knowledge when learning from video…

Fractions are perceived as one of the most difficult areas in school mathematics to learn and teach. The most frequently mentioned factors contributing to the complexity are fractions having five interrelated constructs (part-whole, ratio, operator, quotient and measure) and teachers' pedagogical approaches to address these constructs. The present…

Research indicates the benefits of collaborative learning for supporting academic literacy in content classrooms, especially for diverse and exceptional students such as students with learning disabilities or English learners (ELs) who can become disengaged in content classrooms if they struggle to access complex, content-related texts. Drawing…

One of the primary skills required by mathematics teachers is the ability to provide effective explanations to their students. Using Kay's (2014) theory-based framework for creating instructional videos, this study explored the quality and growth of explanations embedded in mathematical instructional videos created by 37 pre-service teachers…

Prior studies suggest that struggling to make sense of mathematics is a necessary component of learning mathematics with understanding. Little research exists, however, on what the struggles look like for middle school students and how they can be productive. This exploratory case study, which used episodes as units of analysis, examined 186…

For the thirty-seventh year, the Research and Theory Division and the Division of Instructional Design of the Association for Educational Communications and Technology (AECT) sponsored the publication of these Proceedings. Papers published in this volume were presented at the annual AECT Convention in Jacksonville, Florida. This year's Proceedings…
