Abstract

Penelitian ini bertujuan untuk menghasilkan perangkat pembelajaran geometri bangun ruang sisi datar kelas VIII SMP. Perangkat pembelajaran tersebut terdiri atas: Rencana Pelaksanaan Pembelajar-an (RPP), Lembar Kegiatan Siswa (LKS) dan tes hasil belajar. RPP dan LKS menggunakan pendekatan open-ended dengan berorientasi kemampuan berpikir kritis. Penelitian ini merupakan penelitian pengembangan (R & D) yang dikembangkan oleh Borg dan Gall dengan modifikasi. Hasil penelitian disimpulkan bahwa perangkat pembelajaran yang dikembangkan dinyatakan: (1) valid berdasarkan penilaian ahli/praktisi, (2) praktis digunakan berdasarkan: (a) observasi keterlaksanaan pembelajaran, (b) penilaian guru, dan (c) angket respons siswa, dan (3) efektif berdasarkan hasil tes kemampuan berpikir kritis siswa.

Kata Kunci: pengembangan, perangkat pembelajaran geometri, pendekatan open-ended, kemampuan berpikir kritis.

Developing the Learning Kits for the Topics of Geometry Using Open-Ended Approach with Critical Thinking Ability Orientation at Junior High School

Abstract

This study aims at developing the learning kits for the topics Polyhedral of geometry at grade 8^th in Junior High School. The learning kits consist of the Lesson Plans, the Student Worksheets, and the learning achievement test. The Lesson Plans and Student Worksheets use open-ended approach with critical thinking ability orientation. This is a research and development (R&D) study by modifying Borg and Gall’s procedures. The result of study can be concluded that: (1) the learning kits are valid based on experts evaluation, (2) they are practical based on the result of: (a) the learning observation, (b) the teachers evaluation, and (c) the students’ responses questionnaire, and (3) they are effective based on the result of students’ critical thinking ability test.

Keywords: develop, learning kits of geometry, open-ended approach, critical thinking ability.
