Supporting the Assessment of Collaborative Design Activities in Multi-tabletop Classrooms

Abstract

The present study describes a proposed multitabletop system for supporting collaborative database design activities in the classroom. Additionally, two experiments were conducted to evaluate students' and teachers' perceptions of the proposed system potential on aspects of group work assessment such as: ease of grading individuals as well as groups; equality of students' participation; and, capability to accurately reflect individual contributions. Ten educators and 22 students from a Computer Science program participated in the experiments. The findings of this work show that the use of the proposed system impacted positively on the educators' perception about the ease of grading individuals and groups. In addition, distinguishing users in collaborative group work is key for decreasing social-loafing. The results suggest that the proposed system does have potential to support a better group work assessment.

“…Many other works used TUIs or multi-tabletop touch interfaces to track the content of the collaborative task and activity [49], [94], [95]. Echeverria et al [49] used a combination of a TUI-based tool called DBCollab, a personal tablet, and a Kinect sensor to track the activity of students during a database design session in the classroom.…”

“…This feedback improved collaboration. Granda et al [95] used a multi-tabletop TUI for database design. They gave feedback on students' activity to the teachers in colored symbols.…”
