Abstract

This development research aims to produce a science learning kit based on Problem Based Learning to enhance problem-solving skills related to force concepts for elementary school students at Phase B. The research employed a research and development approach consisting of needs analysis, product design, development, validation, and limited implementation stages. Needs analysis was conducted through teacher interviews and classroom observations to identify learning conditions and limitations of instructional media in science lessons. Findings from the analysis served as the foundation for designing the science kit and student worksheets aligned with Problem Based Learning syntax and Polya’s problem-solving indicators. The final product consisted of a science kit containing simple experimental tools and a worksheet book guiding student learning activities. Product validation involved a media expert and a subject matter expert to evaluate content accuracy, design quality, and instructional suitability. Media expert evaluation resulted in a feasibility percentage of 93%, while subject matter expert evaluation reached 96.5%, indicating very high feasibility. Limited implementation was carried out among fourth-grade students through pre-test and post-test administration consisting of eight short-answer questions measuring problem-solving ability. Improvement analysis employed the N-gain formula. Results indicated an N-gain score of 0.3 categorized as moderate improvement. Research findings reveal that the Problem Based Learning–based science kit supports meaningful understanding of force concepts and facilitates structured problem-solving processes. The developed product demonstrates potential as an alternative science learning medium that promotes active learning and higher-order thinking skills in elementary education.

Abstract

Penelitian ini bertujuan untuk menganalisis peningkatan pemahaman konsep matematis siswa sekolah dasar melalui penerapan model pembelajaran RADEC serta membandingkan peningkatan tersebut antara wilayah perkotaan dan pedesaan. Penelitian ini menggunakan pendekatan kuantitatif dengan desain kuasi-eksperimen berupa pretest–posttest group design. Sampel penelitian terdiri atas 30 siswa kelas IV yang masing-masing berasal dari sekolah dasar di wilayah perkotaan dan pedesaan. Instrumen penelitian berupa tes pemahaman konsep matematis yang diberikan sebelum dan sesudah pembelajaran. Data dianalisis menggunakan statistik deskriptif dan inferensial melalui uji paired sample t-test dan independent sample t-test. Hasil penelitian menunjukkan bahwa model pembelajaran RADEC secara signifikan meningkatkan pemahaman konsep matematis siswa baik di wilayah perkotaan maupun pedesaan (p < 0,05). Namun, tidak terdapat perbedaan peningkatan yang signifikan antara kedua wilayah tersebut (p > 0,05). Dengan demikian, model RADEC efektif dan adaptif untuk meningkatkan pemahaman konsep matematis siswa pada berbagai konteks lingkungan sekolah.
