Argumentation, a key scientific practice presented in the "Framework for K-12 Science Education," requires students to construct and critique arguments, but timely evaluation of arguments in large-scale classrooms is challenging. Recent work has shown the potential of automated scoring systems for open response assessments, leveraging…

Tangible technologies and shared interfaces create new paradigms for mediating collaboration through dynamic, synchronous environments, where action is as important as speech for participating and contributing to the activity. However, interaction with shared interfaces has been shown to be inherently susceptible to peer interference, potentially…

This research investigates the role of representational guidance by comparing the effects of two different representational tools. We used a design with two different groups defined by the type of argumentative diagram students co-constructed while working in a computer-supported collaborative learning (CSCL) environment. The Graphical Debate-tool…

Many forms of technological communication exist in non-linear environments and there is potential for new approaches to learning and teaching which may more closely approximate naturalistic and authentic approaches to learning. The following study examined the ways in which high school students were influenced by technology as they wrote and how…

Recent research indicated that students' ability to construct evidence-based explanations in classrooms through scientific inquiry is critical to successful science education. Structured argumentation support environments have been built and used in scientific discourse in the literature. To the best of our knowledge, no research work in the…

For some teachers, the increasing attention to digital and multimodal composing in English and Language Arts classrooms has brought into sharp relief the profession's investment in print as the primary means of expression. Although new forms of communication that combine words, still and moving images, and animation have begun to dominate digital…

The "Convince Me" computer environment supports critical thinking by allowing users to create and evaluate computer-based representations of arguments. This study investigates theoretical and design considerations pertinent to using "Convince Me" as an educational tool to support reasoning about public policy issues. Among…

For the twenty-fifth year, the Research and Theory Division of the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. This is Volume 2 of the 25th Annual Proceedings of Selected Papers On the Practice of Educational Communications and Technology Presented at The National Convention…
