This study investigates perceptions of 29 prospective teachers about a course based on Project-Based Learning (PBL) approach. The course, "Authoring Languages in PC Environment (B-320)" lasted in 14 weeks in fall semester of 2004-2005. In this course each prospective teacher carried out a project that requires designing and developing courseware individually. This study is qualitative in nature and data were collected through an open ended questionnaire composed of seven items and analyzed by content analysis technique. The results show that prospective teachers found PBL as an effective way of learning. It also suggests that when efficient guidance about technical issues and time management is provided, PBL approach can be successfully implemented in computer related courses such as programming language and web designing.
