Abstract
This study aims to: 1) Produce valid, practical and effective quality learning tools, which are developed based on the Problem Based Learning model for class VIII SMP Negeri 3 Pantai Labu- 2) Analyze the increase in students^ mathematical computational thinking skills by using the Problem Based Learning model learning tools. This research is a development research using the 4-D development model which consists of four stages, namely define, design, develop, and disseminate. Learning tools resulting from this study are Learning Implementation Plans (RPP), Student Books (BS), Student Worksheets (LKPD), and Students^ Mathematical Computational Thinking Ability Tests. Based on the research results obtained 1) Problem Based Learning model learning tools have met the valid, practical, and effective criteria in terms of each criterion- 2) There is an increase in students^ Mathematical Computational Thinking skills by using the Problem Based Learning model learning tool seen from the N-gain value in trial I of 0.36 (criterion ^moderate^) increased to 0.51 (criteria ^moderate^) in the test try II.
Keywords: Development of Learning Devices, Problem Based Learning model learning, students^ mathematical computational thinking abilities
