<![CDATA[Collaborative Class Action Research (PTKK) with the aim of improving the creative thinking skills of class VII students at UPT SMPN 10 Gresik. Based on the results of observations, problems were found in the learning process, the majority of students were less active, conventional, most students did not participate enough in learning and creative thinking skills had not yet emerged. The solution will be by applying a learning modelProblem Based Learning (PBL) to improve the creative thinking skills of class VII students at UPT SMPN 10 Gresik on ecology and biodiversity material in the even semester. Learning is carried out in two cycles, each cycle consists of two meetings, namely planning, action, observation and reflection. The data used is in the form of observation sheets and tests. The resulting data shows an increase in creative thinking skills as indicated by a pre-cycle percentage of 65.63%, an increase of 75% in cycle I, while cycle II increased to 87.5%. The final results in cycle II exceeded the target of 80%, so that the application of the problem-based learning model was proven to improve the creative thinking skills of class VII students at UPT SMPN 10 Gresik on ecology and biodiversity in the even semester.
