Creative thinking data collection is using posttest and pretest, while for collaborative ability data collection is by observation sheets. The results showed that (1) the creative thinking ability (mean pretest 32,14 for experiment class and 40,17 for control class, mean posttest 79, 29 for experiment class and 40,83 for control class) and collaborative ability of the class with STEM-integrated project-based learning were superior/got more significant results than the class that used conventional learning models, (2) students' creative abilities emerged into several indicators such as fluency, flexibility, original thinking, and elaborative thinking, (3) collaborative abilities appear in the field based on indicators of confidence, positive attitude, respect, giving encouragement, and building group spirit.
