Abstract
The studi aims to determine the validity, practicality, and effectiveness of teaching materials, and find out the improvement of students’ mathematical problem-solving abilities by using teaching materials that are developed. This type of research is the development using the Dick and Carey development model. This research was conducted at Markus Medan High School, trial I was conducted in class X-IPA while trial II was in class X-IPS. Mathematics learning uses Guided Discovery Learning Model. The results showed that the developed Batak Toba culture based teaching materials could meet valid, practical and effective criteria. Based on expert opinion, the response of students and teachers also states teaching materials can be used easily. Teaching materials meet the completeness of student learning outcomes in a classic way. As for the ability to solve mathematics problem-solving students have increased by 3, 33%. In the first experiment of 83.33% of students who completed, while in the second experiment amounted to 86.66% of students who completed. The conclusion of the research development of teaching materials based on Batak Toba culture fulfills valid, practical and effective criteria. Teaching materials can improve students’ mathematical problem-solving
