This research was motivated by the low ability of students’ mathematical problem solving and lack of their self-esteem, so there was a need of learning model that is able to enhance students’ problem solving and self-esteem. One of the learning models that can be used is CORE (Connecting, Organizing, Reflecting and Extending) mixed with scientific approach. This study aims to determine to compare mathematical problem solving ability and improvement of student selfesteem who get the CORE model mixed with scientific approach and students who received scientific learning. The method used is a quasi-experimental method with population of eighth grade students of SMP Negeri 1 Bayah. Sampling is conducted through purposive sampling technique.
