With the recognition of the importance of collaboration in a design studio and the advancement of technology, increasing numbers of design students collaborate with others in a technology-mediated learning environment (TMLE); however, not all students have positive experiences in TMLEs. One possible reason for unsatisfactory collaboration experiences is that existing text-oriented collaboration technology may not fully support interior design students' needs for spontaneous interaction with visual images. The purpose of the current research was to determine whether a visually supported collaboration technology (VSCT) for designers, enhances students' collaboration experiences in a TMLE. A total of 28 junior interior design students participated in the study, all of whom engaged in similar group projects via two collaboration modalities: face-to-face and VSCT. The results show that collaboration modalities influence students' learning experiences, in particular, achievement and confidence in completing collaborative tasks. When using VSCT, students achieved significantly higher grade and demonstrated higher confidence in completing collaborative tasks compared to face-to-face collaboration; however, no significant differences were reported in either their perception of the collaboration process or their evaluation of the medium in the two collaboration modalities. The findings demonstrate that VSCT enhanced students' collaboration experiences in design studio. Discussion and implications are provided to facilitate design students' positive collaboration experiences in a TMLE.
