- This research is a study of the development of learning devices. This study aims to analyze how the validity, practicality and effectiveness of mathematics learning tools through Geogebra-assisted problem-based learning are developed and analyze how to improve students' mathematical problem-solving abilities after being taught using the developed learning tools. The products produced in this study are learning implementation plans, teacher books, student books, and student activity sheets. The development of this learning device uses a 4D development model developed by Thiagarajan, Semmel and Semmel which consists of four stages, namely, define, design, develop, and disseminate. This research was conducted in two trials in two different classes, namely class XI MS 1 and XI MS 2 in SMA 1 Kabanjahe. Data from the results of this study were analyzed descriptively. The results of the study show that: (1) learning devices developed meet all validity criteria, both content validity and construct validity; (2) learning devices developed meet all practicality criteria, seen from: a) validator assessment and b) implementation of learning devices; (3) learning devices developed meet all effectiveness criteria, viewed from: a) completeness of student learning outcomes, b) student activities, and c) student positive responses; (4) students' mathematical problem solving abilities increase using the learning tools developed. Increased students' mathematical problem solving abilities seen from the results of the post-test trial I and trial II.
