This study aims to produce a Mathematics Learning Tool with Problem-Based Learning Model Using a Realistic Mathematical Approach in Pythagorean Theorem lesson for 8th-grade students of SMP Negeri 1 Tomohon that met valid, practical, and effective criteria. The study employs the ADDIE model of research and development to design and develop learning instruments involved, lesson plan, student's worksheet, a test of learning outcome. Descriptive analysis results in that the development of the problem-based learning model using the realistic mathematical approach produced good learning tools because it met valid criteria based on expert opinion, the teacher's ability to carry out learning was good, students were active during the learning process, students gave positive responses to learning. The developed test of learning outcome meets the criteria of validity, practicality, and effectiveness. It is concluded that the problem-based learning model using a realistic mathematical approach was effective in teaching the Pythagorean Theorem topic to 8th graders of SMP Negeri 1 Tomohon. © Published under licence by IOP Publishing Ltd.
