Pengembangan Perangkat Pembelajaran Aljabar Berbasis Problem Based Learning untuk Mendukung Kemampuan Komunikasi Matematika Siswa Sekolah Menengah Pertama

Abstract

The purpose of this research is to develop learning tools based for Algebra on Problem Based Learning (PBL) to support the mathematics communication ability of Junior High School students. Learning tools developed in this development research is students’ worksheets. The research method used is 4D model, which consists of 4 stages, namely define, design, develop, and disseminate. The results of worksheets’ validation by experts were 4,05 for the layout design and 4,19 for the content (both were categorized as valid). In addition, the students respons that the students’ worksheets were practical (with average of 3,94) and the teacher responses that these were very practical (with average of 4,23). Thus, based on the expert validation as well as the students and teacher of mathematics responses, the learning tools developed have already met the criteria of valid and practical and ready for the field testing to see its effectiveness on students’ mathematics communication ability.

Penerapan Model Problem Based Learning Untuk Meningkatkan Kemampuan Berpikir Kritis Siswa Pada Pembelajaran Matematika [Implementation of the Problem Based Learning Model to Improve Students' Critical Thinking Skills in Mathematics Learning]

“…Tyas (2017) juga menjelaskan tahapan PBL yakni: 1) memberikan orientasi tentang permasalahan kepada mahasiswa, 2) mengorganisasikan siswa untuk meneliti, 3) membantu investigasi mandiri dan kelompok, 4) mengembangkan dan mempresentasikan karya atau laporan, 5) menganalisis dan mengevaluasi proses mengatasi masalah. Indikator PBL meliputi: 1) mengorientasikan peserta didik pada masalah, 2) mengorganisasikan peserta didik untuk belajar, 3) membantu penyelidikan mandiri dan kelompok, 4) mengembangkan dan menyajikan hasil karya serta memamerkannya, 5) menganalisis dan mengevaluasi proses pemecahan masalah (Winarni & Marlina, 2020).…”
