Abstract

Penelitian ini diawali oleh fakta yang ada di lokasi penelitian dan berdasarkan hasil observasi pertama di Prodi Pendidikan Matematika FKIP UNBARI ditemukan mahasiswa belum dapat menjawab secara sempurna materi himpunan pada mata kuliah Teori Probabilitas. Observasi dilaksanakan beberapa tahap maka ditemukan masalah selama proses perkuliahan masalah yang ditemukan yaitu proses perkuliahaan  kurang mendukung untuk menciptakan pembelajaran yang kondusif. Mengacu pada tujuan  penelitian  maka jenis penelitian yang di gunakan adalah jenis penelitian pengembangan (research and  development). Model pengembangan yang dilakukan mengikuti  model pengembangan 4-D (four D), khususnya 3 tahap awal. Tahap-tahap itu adalah : pendefinisian (define), perancangan (design), dan pengembangan (develop). Hasil penelitian menunjukkan bahwa lembar kerja peserta didik (LKPD) berbasis model pembelajaran problem based learning (PBL)  yang dikembangkan pada materi himpunan sudah sangat valid, baik dari segi isi dan konstruk, Praktis dan Efektif. Kata kunci: LKPD, pembelajaran berbasis masalah

Abstract

This study aims to develop a valid and practical Interactive Multimedia-Based Student Worksheet (LKS) to foster students’ mathematical creative thinking skills. The research adopts a development research design using the ADDIE model, which includes the stages of Analysis (curriculum, students, and learning material), Design, Development, Implementation, and Evaluation. Instruments used in this study consist of validation sheets for learning tools and student response questionnaires for measuring practicality. The research was conducted at SMA Negeri 6 Bengkulu City with Grade X students during the 2024/2025 academic year, focusing on the topic of arithmetic sequences and series. The results demonstrate that the developed interactive multimedia-based LKS is both valid and practical. Expert validation results indicate that the material aspect achieved an average score of 3.61 and the media aspect achieved 3.67, both categorized as “highly appropriate.” In terms of practicality, analysis of student response questionnaires yielded a score of 78.3%, which also falls into the “highly practical” category. These findings suggest that the developed LKS is a feasible and effective tool for enhancing students’ mathematical creative thinking skills in secondary education settings. Keywords: Interactive Multimedia-Based Student Worksheet (LKS), CreativeThinking, ADDIE Development Model
