PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK BERBASIS PROBLEM BASED LEARNING DALAM PEMBELAJARAN MATEMATIKA SISWA KELAS IV SEKOLAH DASAR

Penelitian ini dilakukan untuk mengetahui pengembangan dan kelayakan dari media pembelajaran lembar kerja peserta didik (LKPD) berbasis problem based learning dalam pembelajaran matematika kelas IV Sekolah Dasar. Metode penelitian yang digunakan dalam penelitian ini adalah penelitian dan pengembangan (Research and Development) yang menggunakan empat tahapan dari model penelitian dan pengembangan Borg and Gall, yaitu: 1) research and information collecting, 2) Planning ,3) develop preliminary form a product, 4) preliminary field testing 5) main product revision, 6) main field testing 7) operational product revision 8) Operational Field Testing, 9) Final Product Revision, 10) Desimination. Hasil dari penelitian dan pengembangan ini adalah produk LKPD berbasis problem based learning dalam pembelajaran matematika kelas IV sekolah dasar. Tingkat kelayakan berdasarkan hasil persentase penilaian ahli materi, ahli media pembelajaran, dan ahli bahasa masing-masing mendapatkan 90.47%, 82.28%, dan 73.3% dengan kriteria “sangat layak”. Selanjutnya, respon peserta didik terhadap produk saat diuji cobakan dalam tahap main field testing produk LKPD juga tidak memerlukan perbaikan serta mendapatkan presentase sebesar 95.17% dengan kriteria “sangat baik”. Berdasarkan hasi wawancara dengan guru kelas IV, guru tertarik untuk menggunakan produk LKPD berbasis problem based learning dalam kegiatan pembelajaran matematika didalam kelas. Berdasarkan hal tersebut, dapat disimpulkan bahwa LKPD berbasis problem based learning layak digunakan sebagai salah satu bahan ajar matematika pada pembelajaran geometri. This study was conducted to determine the development and feasibility of learning media student worksheets (LKPD) based on Problem Based Learning in learning mathematics for grade IV elementary schools. The research method used in this study is research and development (Research and Development) which uses four stages of the Borg and Gall research and development model, namely: 1) research and information collecting, 2) Planning, 3) develop preliminary form a product, 4) preliminary field testing 5) main product revision, 6) main field testing 7) operational product revision 8) operational field testing, 9) final product revision, 10) desimination. The result of this research and development is a problem based learning LKPD product in the fourth grade elementary school mathematics learning. The feasibility level based on the results of the percentage assessment of material experts, learning media experts, and linguists respectively got 90.47%, 82.28%, and 73.3% with the criteria of "very feasible". Furthermore, the response of students to the product when it was tested in the main field testing stage of the LKPD problem based product also did not require improvement and got a percentage of 95.17% with the criteria of "very good". Based on the results of interviews with fourth grade teachers, teachers are interested in using problem-based learning LKPD products in mathematics learning activities in the classroom. Based on this, it can be concluded that problem-based learning LKPD is appropriate to be used as one of the mathematics teaching materials in geometry learning
