Abstract

This study aims to conduct a comparative analysis of three mathematics textbooks on the topic of Polyhedrons, namely two textbooks from Indonesia (KTSP 2006 and Kurikulum Merdeka 2022) and one textbook from Singapore (New Syllabus Mathematics 2018). The method used is descriptive comparative with document analysis techniques. The focus of the study includes the presentation of facts, concepts, and principles, as well as question analysis based on Bloom’s Taxonomy cognitive levels, alignment with the PISA framework, and problem-solving components. The results indicate that the Kurikulum Merdeka textbook stands out in its variety of cognitive levels (C1–C6) and integration of PISA-type questions. The KTSP textbook follows a more deductive approach and lacks higher-order thinking questions, while the Singaporean textbook balances inductive and deductive approaches but only covers C3–C4 levels. All three textbooks include problem-solving tasks with varying levels of complexity. These findings offer insights for the development of more effective and context-based mathematics textbooks.

Abstract

Textbooks are essential learning tools that significantly influence students' comprehension of mathematical concepts, including the foundational topic of sets. This study aimed to analyze how set materials are presented in Indonesian and Fijian mathematics textbooks, focusing on facts, concepts, principles and errors, cognitive levels, problem-solving, and alignment with the Programme for International Student Assessment (PISA) framework. Using a qualitative descriptive-comparative method, the study examined three textbooks: Indonesia’s KTSP (2011), Merdeka Curriculum (2022), and a Fijian mathematics book. Data were collected through document analysis. The findings revealed distinct presentation approaches: KTSP emphasizes symbols and formal definitions; the Merdeka Curriculum uses real-life contexts; and the Fijian book adopts a simple, visual style. Regarding cognitive levels, KTSP questions are mostly C1–C2, Merdeka Curriculum texkbook includes C4–C5, while Fiji remains at C1–C3. However, all three lack sufficient alignment with PISA question types. In terms of problem-solving, KTSP tends to be procedural, the Merdeka Curriculum is more reflective, and Fiji lacks problem-solving tasks. These findings highlight the need for textbooks to include more contextual and higher-order thinking problems to support students’ mathematical literacy and deeper understanding.
