Abstract:
Lembar Kerja Peserta Didik (LPKD) can help students understand the concept of material, both theoretically and in real events that often occur in everyday life. This study tries to determine the development process and quality of LKPD to improve students' understanding the concepts of algebra. The development research used refers to the Plomps model, which includes 4 phases: (a) the initial investigation, (b) the design, (c) the realization, and (d) the test, evaluation, and revision. The product assessment instrument used was the LKPD validation sheet, the LKPD observance sheet, student and teacher response questionnaires, student and teacher activity observation sheets, and tests of students' ability to understand mathematical concepts. The LKPD that was designed and tested on grade VII students at one of the schools in Soppeng had met the criteria of being valid, effective, and practical.
Abstrak:
Lembar Kerja Peserta Didik (LPKD) berbasis masalah dapat membantu peserta didik memahami konsep materi, baik secara teori maupun dalam peristiwa nyata yang sering terjadi dalam kehidupan sehari-hari. Penelitian ini mencoba mengetahui proses pengembangan dan kualitas LKPD matematika berbasis masalah untuk meningkatkan pemahaman konsep aljabar peserta didik. Penelitian pengembangan yang digunakan mengacu pada model pengembangan Plomp, yang meliputi 4 fase, yaitu: (a) fase investigasi awal, (b) fase desain, (c) fase realisasi, dan (d) fase tes, evaluasi, dan revisi. Instrumen penilaian produk yang digunakan adalah lembar validasi LKPD, lembar pengamatan keterlaksaan LKPD, angket respon peserta didik dan guru, lembar pengamatan aktivitas peserta didik dan guru, dan tes kemampuan pemahaman konsep matematika peserta didik. LKPD yang didesain dan diujicobakan kepada siswa kelas VII di salah satu sekolah di Soppeng telah memenuhi kriteria valid, efektif dan praktis.
