Application of Cooperative Problem-Based Learning Model to Develop Creativity and Foster Democracy, and Improve Student Learning Outcomes in Chemistry in High School
Implementation of cooperative problem base learning models in developing creativity,  democracy and improve student learning outcomes in chemistry have been conducted in this study. There are 132 students as research subject from 5 high school located in the province of North Sumatera. The study was conducted with a quasi-experimental approach. Instruments are standardized tests used to measure student learning outcomes, while the instrument is used to measure the development of students' creativity and democracy with the observation sheet with standardized indicators. The results showed that the Cooperative Problem Base Learning Model can significantly improve student learning outcomes of chemistry (sign. 0,000). In addition, this learning model can develop students' creativity and democracy to the effectiveness of 84.1 % and 86.4 % . Keywords : Learning model, creativity, democracy, student learning outcome.
