In this study, different degrees of synchronous and asynchronous online social interactions are investigated in the context of an online educational roleplaying simulation game that is played across multiple classrooms simultaneously to teach argumentation skills and social studies. Results from 45 K-12 middle school social studies teachers and…

Results of research on intentions and effects of first- and second-order argument scaffolding of computer-supported collaborative argumentation competence development and domain-specific knowledge acquisition are ambivalent. A systematic review of research in secondary and higher education (SE and HE) has been conducted to clarify and synthesise…

As lesson study becomes more prevalent, there is a need to continuously develop theoretical and methodological infrastructure to support and refine its use. In this article, we present a critical methodological analysis of the challenges and benefits of using Toulmin's argumentation model in mathematics education to assess the debriefing phase of…

What makes a leader in an online learning environment? This question is approached from three angles in this study: online activity, language quality, and social background. This study examines the simulation data of the 2015 GlobalEd 2 Project, which consists of 337 7th and 8th grade students representing 18 countries. The three dimensions were…

As computers and the Internet are increasingly employed in language teaching and learning, preparing teachers for the impending reality of online teaching is of paramount importance. This study investigated 10 in-service teachers participating in an online role-play as part of a digital education methods course to acquire an understanding of the…

This paper explores student interactions from the Virtual Math Teams-With-GeoGebra Project, a computer-supported collaborative learning environment that allows individuals to interact, collaborate, and discuss user-created dynamic mathematics objects. Previous studies of virtual math teams have focused on the coconstruction of a joint problem…

Structured argumentation support environments have been built and used in scientific discourse in the literature. However, to the best our knowledge, there is no research work in the literature examining whether student's knowledge has grown during learning activities with asynchronous argumentation. In this work, an intelligent computer-supported…

In recent research, little attention has been paid to issues of methodology and analysis methods to evaluate the quality of the collaborative learning community. To address such issues, an attempt is made to adopt the Activity System Model as an analytical framework to examine the relationship between computer supported collaborative learning…

Computer conferencing provides a new site for students to develop and rehearse argumentation skills, but much remains to be learnt about how to encourage and support students in this environment. Asynchronous text-based discussion differs in significant ways from face-to-face discussion, creating a need for specially designed schemes for analysis.…

The ability to argue is an important academic goal in secondary education. This paper reports on an exploratory study which investigated how asynchronous text-based conferencing provides a new site for school students to rehearse and develop their skills in argumentation. The study used linguistic tools of analysis to investigate two key…

For the thirty-fifth year, the Research and Theory Division of the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented at the national AECT Convention in Louisville, Kentucky. The Proceedings of AECT's Convention are published in two…
