Abstract

ABSTRAK PENGEMBANGAN BAHAN AJAR BERBASIS CREATIVE PROBLEM SOLVING PADA MATERI PELUANG SMP/MTS Oleh : SITI HOTIMAH Penelitian ini bertujuan untuk mengembangkan bahan ajar berbasis model Creative Problem Solving (CPS) pada materi peluang di tingkat SMP/MTs. Latar belakang penelitian ini adalah masih rendahnya pemahaman konsep peluang serta kurangnya minat dan keterlibatan aktif peserta didik dalam pembelajaran matematika. Penelitian ini menggunakan metode Research and Development (R&D) dengan mengadopsi model pengembangan 4D yang terdiri atas tahapan Define, Design, Develop, dan Disseminate. Produk yang dihasilkan berupa Lembar Kerja Peserta Didik (LKPD) yang terstruktur berdasarkan lima tahapan model CPS, yaitu fact finding, problem finding, idea finding, solution finding, dan acceptance finding. Hasil validasi oleh para ahli serta uji coba terbatas menunjukkan bahwa bahan ajar yang dikembangkan memenuhi kriteria kelayakan dari segi isi, bahasa, dan penyajian. Bahan ajar ini dinilai efektif dalam meningkatkan pemahaman konsep peluang, memfasilitasi proses berpikir kreatif, serta mendorong partisipasi aktif peserta didik dalam pembelajaran. Dengan demikian, pengembangan bahan ajar berbasis CPS dapat menjadi alternatif inovatif dalam pembelajaran matematika yang lebih kontekstual dan berpusat pada peserta didik.

The study is motivated by students’ low conceptual understanding of probability, as well as limited motivation and engagement in mathematics learning. Employing the Research and Development (R&D) methodology, this study utilizes the 4D development model comprising the stages of Define, Design, Develop, and Disseminate. The resulting product is a Student Worksheet (LKPD) designed according to the five phases of the CPS model: fact finding, problem finding, idea finding, solution finding, and acceptance finding. Expert validation and limited field testing indicated that the developed instructional material meets the standards of content relevance, linguistic clarity, and instructional presentation. Moreover, the materials proved effective in enhancing students' conceptual understanding, fostering creative thinking, and promoting active learning participation. Therefore, CPS-based instructional material can serve as an innovative alternative for delivering contextual and student-centered mathematics education. Keywords: Instructional Material Development, Creative Problem Solving (CPS), Probability, Mathematics, Student Worksheet.
