Pengembangan Bahan Ajar Volume Bangun Ruang Berbasis Pendekatan Contextual Teaching And Learning Di Sekolah Dasar

Abstract

This research is motivated by the fact in elementary schools that there is no development of teaching materials for volumes of geometric figures and the relationship of the cube to the cube root with the Contextual Teaching and Learning (CTL) approach. This study aims to develop teaching materials for volume and cube relationships with cube roots using a valid and practical CTL approach for class V Elementary School using Hamzah's ADDIE development model. With the stages of analysis, design, develop, implement, evaluate. The subjects of this study were 3 experts, 1 teacher for class V and 7 students for class V at SDN 10 Sasai Kandang. The instruments used are expert validation sheets and teacher and student response questionnaires. The results of this study indicate that: (1) The teaching materials of volume and cube relationships with cube roots using the CTL approach are declared very valid for use by material experts, linguists and design experts with an average value of 90.88%. (2) The response of teachers and students to teaching materials volumes of geometric figures and the relationship of the cube to the cube root with the CTL approach scored 94.66% and 95.80% with very practical criteria.
