Abstract This research aims to determine the improvement of students’ mathematical creative thinking ability through Problem Centered Learning (PCL) approach. This research is a quasi-experimental with a non-equivalent research design. The population of this research were the eighth-grade students of SMP Negeri in Bandung. The sample of this research was determined by purposive sampling. The sample consisted of 62 students who were divided into two classes, experimental class and control class. The experimental class uses the PCL approach, while the control class uses conventional learning. Each class consists of 31 students. The data of students’ mathematical creative thinking ability were obtained by using test techniques. The improvement was proven by n-gain value of students’ pre-test and post-test. The conclusions obtained from the data analysis and discussion, there is a significant difference in the improvement mathematical creative thinking ability between high EMA in the PCL group and medium EMA in conventional learning. Based on EMA, PCL can be applied in high EMA classes. While students with medium and low EMA need further research so that students’ mathematical abilities can be improved by PCL.

This research aims to analysis students' geometric thinking ability and theoretically examine the process-oriented guided iquiry (POGIL) model. This study uses qualitative approach with descriptive method because this research was done without any treatment on subjects. Data were collected naturally. This study was conducted in one of the State Junior High School in Bandung. The population was second grade students and the sample was 32 students. Data of students' geometric thinking ability were collected through geometric thinking test. These questions are made based on the characteristics of geometry thinking based on van hiele's theory. Based on the results of the analysis and discussion, students' geometric thinking ability is still low so it needs to be improved. Therefore, an effort is needed to overcome the problems related to students' geometric thinking ability. One of the efforts that can be done by doing the learning that can facilitate the students to construct their own geometry concept, especially quadrilateral's concepts so that students' geometric thinking ability can enhance maximally. Based on study of the theory, one of the learning models that can enhance the students' geometric thinking ability is POGIL model.
