This study explored the effects of student engagement in a knowledge-building (KB) environment on their collaborative learning process and the perceived creative climate of that environment. The participants were 30 college students who undertook a living technology course in which KB were employed. The main data sources include students' online discourse and a creative climate questionnaire. The findings indicate that the students became progressively more collaborative and productive over time, and they also tended to perceive the climate of the learning environment as highly supportive of knowledge creation. Implications for designing creative learning environments are discussed.
