Keywords:higher order thinking, problem based learning, elementary school mathematic
High-level thinking skills are essential to be developed since elementary school and should be the focus in any learning activity, especially in learning mathematics. One of the teaching models that can help students develop higher order thinking skills is Problem Based Learning (PBL) which emphasizes problem solving as the center of teaching and learning activities. This study aims to explain the improvement of higher order thinking skills through the application of Problem Based Learning model in mathematics learning. The research conducted was a Classroom Action Research (PTK) which lasted for two cycles. The research includes planning activities of action implementation and observation, and reflection. Data collected in the form of learning development data, syntax implementation, and higher order thinking skills test results. The results of this study consisted of two cycles: (1) cycle I of the application of the Problem Based Learning model on higher order thinking skills with an average of 65.2%; (2) cycle II follow-up of weaknesses and shortcomings in the first cycle, at this stage the results of higher order thinking skills increased by 78.2%. Based on this review, it can be concluded that the application of the Problem Based Learning model in learning mathematics can improve students' higher order thinking skills.
