Summary

Penelitian ini bertujuan untuk mengembangkan produk berupa Lembar Kerja Peserta Didik (LKPD) berbasis Problem Based Learning untuk meningkatkan kemampuan berpikir kritis pada matematika fase B materi bilangan pecahan. Lembar Kerja Peserta Didik (LKPD) berbasis Problem Based Learning disusun berdasarkan lima sintaks Problem Based Learning, yaitu orientasi pada masalah, pengorganisasian siswa belajar, membantu penyelidikan belajar, mengembangkan hasil karya, dan menganalisis serta mengevaluasi. Penelitian ini dilakukan karena rendahnya kemampuan berpikir kritis peserta didik dalam menyelesaikan soal berbasis masalah pada mata pelajaran matematika sehingga diperlukan optimalisasi perangkat pembelajaran. Peneliti memilih LKPD sebagai salah satu upaya dalam meningkatkan kemampuan berpikir kritis. Metode yang digunakan dalam penelitian ini adalah Design and Development (D&D) dengan model pengembangan analysis, design, development, implementation, evaluation (ADDIE). Desain LKPD berbasis Problem Based Learning meliputi cover, identitas kelompok, capaian pembelajaran, petunjuk pengerjaan, pertanyaan diskusi, dan lembar kegiatan. Instrumen dalam penelitian ini antara lain, lembar observasi, pedoman tes, dan lembar angket ahli. Subjek penelitian ini melibatkan ahli, praktisi pembelajar fase B, praktisi bagian kurikulum, dan peserta didik fase B. Hasil uji coba produk mendapatkan respons signifikan dari peserta didik serta peningkatan rata-rata yang diperoleh dari pre-test dan post-test. Selain itu, diperoleh hasil uji N-gain sebesar 84,5% dengan kriteria efektif. Berdasarkan hal tersebut, Lembar Kerja Peserta Didik (LKPD) berbasis Problem Based Learning mata pelajaran matematika materi bilangan pecahan fase B ini layak digunakan dan mampu meningkatkan kemampuan berpikir kritis peserta didik fase B Sekolah Dasar. This study aims to develop a product in the form of Problem Based Learning Student Worksheets (SW) to improve critical thinking skills in mathematics phase B on fractional numbers. Problem Based Learning Student Worksheets (SW) based on Problem Based Learning are structured based on five Problem Based Learning syntax, namely problem orientation, organizing student learning, assisting learning investigations, developing work results, and analyzing and evaluating. This research is based on the low ability of students to think critically in solving problem-based questions in mathematics so that optimization of learning tools is needed, the researcher chose Student Worksheets to improve this ability. The method used in this study is Design and Development (D&D) with the analysis, design, development, implementation, evaluation (ADDIE) development model. Problem Based Learning worksheet design includes cover, group identity, learning outcomes, work instructions, discussion questions, and activity sheets. The instruments in this study included observation sheets, test guidelines, and expert questionnaires. The subjects of this study involved experts, practitioners of phase B learners, practitioners of the curriculum section, and phase B students. The product trial results obtained significant responses from students as well as an increase in the average obtained from the pre-test and post-test. In addition, the results of the N-gain test were obtained by 84.5% with effective criteria. Based on this, Student Worksheets (SW) based on Problem Based Learning for mathematics subject matter of phase B fractions are feasible to use and are able to improve the critical thinking skills of Phase B elementary school students.
