Abstract

Penelitian ini dilatarbelakangi oleh minimnya pengembangan bahan ajar berupa LKPD berbasis pendidikan matematika realistik serta kemampuan representasi matematis siswa yang masih rendah.  Penelitian ini bertujuan untuk menghasilkan LKPD berbasis pendekatan pendidikan matematika realistik Indonesia (PMRI) untuk meningkatkan kemampuan representasi matematis siswa berdasarkan kevalidan, kemenarikan, kepraktisan, dan keefektifan pada materi sistem persamaan linear tiga variabel (SPLTV). Jenis penelitian ini merupakan penelitian pengembangan atau Research and Development (R&D) dengan mengikuti tahap-tahap model pengembangan 4-D yang terdiri dari define (pendefinisian), design (perencanaan), develop (pengembangan), dan disseminate (penyebaran). Subjek dalam penelitian ini adalah peserta didik kelas X IPA 1 SMA N 1 Batanghari sebanyak 23 peserta didik. Instrumen yang digunakan adalah lembar validasi ahli, lembar angket respon peserta didik, lembar angket kepraktisan guru, dan instrument tes. Hasil penelitian menunjukkan kualitas LKPD memenuhi kriteria kevalidan dengan skor rata- rata 3,55 dalam kategori “sangat valid”. Hasil respon peserta didik pada aspek kemenarikan diperoleh persentase 89,8% dengan kategori “sangat menarik”. Hasil angket kepraktisan diperoleh skor rata-rata 3,9 dengan kategori “sangat praktis”. Sedangkan hasil tes pada aspek keefektifan memenuhi kriteria “efektif” dengan persentase ketuntasan belajar sebesar 82,6% dengan kategori “sangat baik”. Sehingga dapat disimpulkan bahwa LKPD memenuhi kriteria valid, menarik, praktis, dan efektif sehingga dapat digunakan dalam pembelajaran.Kata Kunci: Kemampuan Representasi, LKPD, Pendekatan PMRI

Abstract

This study aims to produce interactive digital teaching materials. The teaching materials are in the form of flipbooks that are integrated with live worksheet and youtube applications and are presented online to students via links. This research is motivated by the lack of teaching materials that are suitable for learning in the pandemic period and the lack of learning activities that involve students to actively participate in finding mathematical concepts. Many teachers do not have teaching materials because they follow the learning system from home. As a result, students also do not have a guide to study the material independently so that teachers and students alike have difficulty in carrying out the learning process. Therefore, to help students understand the material with a series of daily activities that can be done at home, students are given teaching materials that can be accessed independently. This research is a design research with the type of development study. The subjects of this study were seventh grade students of SMPT IT Ar Raihan Bandarlampung. The results showed that the teaching materials developed had met the valid criteria based on the validator's assessment and showed a potential effect as seen from the percentage of student learning completeness which was more than 70%.
