Abstract

Penelitian ini bertujuan untuk mengembangkan perangkat pembelajaran matematika berstandar NCTM (National Council of Teachers of Mathematics) di SMP Kelas VII pada pokok bahasan statistika. Jenis penelitian yang dilakukan dalam penelitian ini adalah penelitian pengembangan. Pengembangan dilakukan berdasarkan pada model 4-D (four-D Model), Thiagarajan Semmel & Semmel yang mana dalam proses pengembangannya terdapat empat tahap pengembangan yaitu pendefinisian (define), desain (design), pengembangan (develop) dan penyebaran (disseminate). Metode pengumpulan data yang dilakukan dalam penelitian adalah lembar validasi instrumen perangkat pembelajaran, observasi, wawancara, dan tes hasil belajar. Selanjutnya data yang diperoleh dianalisis oleh kualitatif deskriptif untuk memenuhi prestasi kriteria menelusuri kevalidan, kepraktisan dan efektivitas. Berdasarkan hasil analisis data, perangkat pembelajaran dikategorikan baik dan memenuhi kriteria valid, praktis dan efektif. Kata Kunci: NCTM, Statistika, Model 4-D

Abstract

Logical thinking is the process of drawing conclusions based on facts through systematic steps and relevant arguments. This ability can be developed through mathematics learning, especially in problem-solving. This study aims to describe the logical thinking profile of junior high school students in solving AKM numeracy problems in algebra content.The research employs a descriptive method with a qualitative approach. The research instruments consist of two AKM numeracy problems related to systems of linear equations in two variables (SPLDV) and number patterns, as well as a validated semi-structured interview guide. Data were collected through a logical thinking test and interviews to identify indicators of logical thinking, namely coherence in reasoning, argumentation ability, and conclusion drawing. The test was administered to 30 eighth-grade students from SMP Negeri 1 Genteng. The results showed that two students met all indicators of logical thinking. These students were able to understand the problem by clearly writing down important information using their own words. They planned their solutions logically, applying the elimination and substitution methods for SPLDV problems and identifying number patterns in different ways. Their problem-solving steps aligned with Polya’s stages: understanding the problem, planning, implementing, and reviewing. Both students wrote conclusions supported by logical reasoning.
