Abstract
This research is motivated by the low ability of mathematical reflective thinking in junior high school students. The purpose of this research is to describe the development of Problem-Based Learning-based E-LKPD to improve the mathematical reflective thinking skills of junior high school students and to determine the feasibility of the developed E-LKPD. This development research uses a development model with seven stages including potentials and problems, information/data collection, product design, design validation, improvement (revision), limited trials, and product revisions. The validation of this development product was tested by 3 experts, including 1 material expert, 1 practitioner expert, and 2 media experts who had carried out tests on the developed E-LKPD teaching materials. Material validation results show a percentage of 88.80% in the "Very Valid" category, media validation results show a percentage of 82% in the "Valid Enough" category. The E-LKPD was tested on 10 grade VIII junior high school students. The results of student responses based on open and closed questionnaires show a percentage of 96.67% in the "Very Valid" category. Based on these results, E-LKPD with Problem Based Learning on the ability to think reflectively mathematically can be declared feasible to be used as teaching material in learning mathematics, especially material for flat sided spaces.

| Additional Information: | Penelitian ini dilatarbelakangi rendahnya kemampuan berpikir reflektif matematis pada siswa SMP. Tujuan penelitian ini untuk mendeskripsikan pengembangan E-LKPD berbasis Problem Based Learning untuk meningkatkan kemampuan berpikir reflektif matematis siswa SMP dan mengetahui kelayakan dari E-LKPD yang dikembangkan. Penelitian pengembangan ini menggunakan model pengembangan dengan tujuh tahapan diantaranya potensi dan masalah, pengumpulan informasi/data, desain produk, validasi desain, perbaikan (revisi), uji coba terbatas, dan revisi produk. Validasi produk pengembangan ini diuji oleh 3 ahli, diantanya 1 ahli materi, 1 ahli praktisi, dan 2 ahli media telah melaksanakan pengujian terhadap bahan ajar E-LKPD yang dikembangkan. Hasil validasi materi menunjukkan persentase 88,80% dengan kategori “Sangat Valid”, hasil validasi media menunjukan persentase 82% dengan kategori “Cukup Valid”. E-LKPD tersebut diujicobakan kepada 10 siswa SMP kelas VIII. Hasil respon siswa berdasarkan angket terbuka dan tertutup menunjukan persentase 96,67% dengan kategori “Sangat Valid”. Berdasarkan hasil tersebut, E-LKPD dengan Problem Based Learning terhadap kemampuan berpikir reflektif matematis dapat dinyatakan layak untuk dipergunakan sebagai bahan ajar dalam pembelajaran matematika khususnya materi bangun ruang sisi datar. | |||||||||
