Abstract
This study aims to analyze the validity, effectiveness and practicality of learning materials based on the Contextual Teaching and Learning Model with the Karo Culture Context (CTL-KBK) as well as to improve students' mathematical problem solving abilities and self-efficacy. The development model of this research uses 4D (Thiagarajan). The subjects in this study were seventh grade students of SMP Negeri 1 Berastagi.The results showed that: 1) the CTL-KBK-based teaching materials developed had met the criteria of being valid, practical and effective. 2) there is an increase in students problem solving abilities using CTL-KCC based teaching materials, increasing from first trial 0.30 to 0.47 in second trial and the self-efficacy of students using CTL-KCC based teaching materials increased from first trial 0.31 to 0.39 in the second trial.
