Designing web technology courses that match students' knowledge background and emphasize students' hands-on experience is imperative yet challenging. This paper discusses a new approach to teaching web technologies, particularly, open source Web 2.0 technologies, in which a combination of studios, mini-lectures, presentations and tutorials, class blogs, and wikis is used. We reported two case studies to demonstrate and evaluate how this approach was used in two web technology courses--one graduate level and the other undergraduate. Based upon survey results and written evaluations from the class blogs and wikis, students feel this new approach makes the course one of their most positive and valuable learning experiences. Educators teach various new and advancing web technologies in Information and Computer Science courses today. Tested and evaluated in Web 2.0 technology courses, we believe that this studio centered approach can benefit both teaching and learning in a variety of web technology courses.
