<![CDATA[The purpose of research is improve problem solving skills in the stories matter of solid geometry by applying the Creative Problem Solving (CPS) learning model. This research is Classroom Action Research with two cycles. The subjects of this research were students of VB class at SD Negeri Danukusuman in the 2018/2019 academic year, totaling 32 students. This research uses data collection techniques in the form of interviews, observations, tests, and documentation with data analysis of source triangulation, technique triangulation, and content validity. The analysis of the data used is the interactive analysis model of Miles-Huberman. The initial conditions of problem solving skills of VB class students showed 18.75% classically. The first cycle began with the first learning resulting in a percentage of 38.7% in classical, the second learning was 40% in classical, and the third learning was 51.75% in classical. The study continued with the second cycle with the percentage of achievement at the first learning amounting to 73.1% in classical, the second learning was 82.15%, and the third learning was 87.5% in classical terms.Keywords: problem solving skills, creative problem solving learning model, stories matter, solid geometry]]>
