Abstract

Critical thinking skills are crucial for students as they are closely tied to their problem-solving capabilities. This study aims to develop a teaching module integrated with the ethnomathematics of the Jam Gadang architecture to enhance students' critical thinking skills on the topic of flat shapes. This research adopts a Research and Development (RD) approach using the Plomp model. The study involves fifth-grade students from a state elementary school in Sungai Jariang in a one-to-one and small-group method trial class, and a state elementary school in Pahambatan Balingka as a field trial class. Data analysis employs validity analysis techniques, practicality analysis techniques utilizing a Likert scale, and effectiveness analysis techniques using a one-group pretest-posttest design. The research instruments include a questionnaire and a critical thinking test. Validation of the teaching module instrument scored 3.6, and student worksheets (LKPD) scored 3.83, both falling into the highly valid category. The practicality of the teaching module reached 92.86%, while the practicality of student worksheets (LKPD) reported 91.18% from the students' perspective and 95.85% from the teacher's perspective, all categorized as highly practical. The Jam Gadang integrated learning modules for ethnomathematics were declared effective in the medium category based on the calculated N-Gain value in field trials of 0.51. Thus, this learning module is suitable for use in improving students' critical thinking skills.
开发基于民族数学的模块,提高学生的批判性思维能力
批判性思维能力与学生解决问题的能力密切相关,因此对学生至关重要。本研究旨在开发一个与贾姆嘎当建筑民族数学相结合的教学模块,以提高学生对平面图形这一主题的批判性思维能力。本研究采用研究与发展(RD)方法,使用 Plomp 模型。研究对象包括来自 Sungai Jariang 一所州立小学的五年级学生,他们在一对一和小组教学法试验班学习,以及来自 Pahambatan Balingka 一所州立小学的实地试验班学习。数据分析采用了有效性分析技术、利用李克特量表进行的实用性分析技术以及采用单组前测后测设计进行的有效性分析技术。研究工具包括调查问卷和批判性思维测试。教学模块工具的效度为 3.6,学生工作表(LKPD)的效度为 3.83,均属于高度效度类别。教学模块的实用性达到 92.86%,而学生作业单(LKPD)的实用性从学生的角度来看为 91.18%,从教师的角度来看为 95.85%,均属于高度实用类。Jam Gadang 民族数学综合学习模块在实地试验中计算的 N 增益值为 0.51,因此被宣布为中等有效。因此,该学习模块适合用于提高学生的批判性思维能力。
