Examining the effectiveness of a multimedia case-based environment for teaching technology integration to Korean preservice teachers

The study described in this paper examined the effectiveness of a multimedia case-based learning environment to teach technology integration to Korean preservice teachers. The structure and philosophy behind the use of embedded video in an online, multimedia system and the data collected from 103 preservice teachers are presented and discussed. The overall finding shows that there was no significant difference from pre- to posttest among the lecture, the case-based, and the mixed environment groups. However, low prior knowledge students improved more when they learned about technology integration with the mixed method than with the case-based method alone. Discussion about this result and its educational implications conclude the paper.
