This study was conducted in a curriculum development project aiming to design teaching materials and to implement an innovative curriculum regarding green building and alternative fuel vehicle for elementary school students. Researchers employed CIPP evaluation model to assess the effectiveness of the curriculum development and implementation. The study used both qualitative and quantitative research methods, including participant observations in the project, interviews with the curriculum design team (two teachers and two university professors), and collection of worksheets and questionnaires written by the sixth grade students of those two participate schools. Through brainstorming and team teaching, the teachers received an opportunity of professional development. The concepts of "energy saving" and "carbon reduction" were introduced to students by integrating the cases from everyday life. Results indicate that students were interested in the learning activities, and the curriculum could enhance the students’ understandings about "green building," "alternative fuel vehicle", and "energy saving and carbon reduction". This study supports that the CIPP model is helpful for the development of such innovative curricula. Suggestions about the implementation of the curricula are also provided.
