Abstract
The aim of the reasearch are to: 1) produce valid creteria, practical creteria and effective creteria on PBL tools for students of SMP N 1 Stabat; 2) Analyze the increase in the mathematical critical thinking skills (TKBM) of Junior High School Student N1 Stabat after being taught using the Geogebra-assisted Poblem Based Learning (PBL) tool; This research is included in development research using the Thiagarajan 4D learning device development model. This research was conducted at Junior High School 1 Stabat. The results of the study show that: 1) the geogebra-assisted problem-based learning tool in improving TKBM that has been developed meets valid, practical and effective criteria; 2) The improvement of TKBM.
