This design case details the ten-year (2014-present) iterative process to design and develop a graph-based computer-assisted program to support middle school students' development of collaborative argumentation. We begin by describing the first two iterations of the design and discuss how we learned from the process failures. This paper focuses on…

The objective of this project was to address design gaps in previous programs that address scientific argumentation in middle schools. We adopted gamification mechanics (e.g., stimulus and response and progression) to design a computer-assisted program to better support students' development of scientific argumentation. In this paper, we describe…

This design case describes the work involved in developing a digital game-based learning environment, work that was part of a PhD research project. The designer was involved in all aspects of the project: conducting research into content that was included in the game, exploring the gaming platform (Second Life), adapting scientific literature for…
