Abstract

Pembelajaran matematika realistik yang dipadukan dengan kearifan lokal Toraja (ukiran Toraja) dan memperhatikan gaya kognitif merupakan sebuah ide yang diharapkan dapat membantu siswa dalam memahami materi, menarik bagi siswa, dan mampu mengaplikasikan matematika dalam kehidupan sehari-hari. Tujuan dari penelitian ini adalah untuk mendeskripsikan peningkatan hasil belajar siswa field independent yang diajar dengan pembelajaran matematika realistik menggunakan ukiran Toraja. Penelitian ini bersifat deskriptif kuantitatif, subjek penelitian yaitu siswa kelas VIIIa SMPN 2 Balusu yang berjumlah 17 orang. Peneliti menggunakan desain one group pretes-postest. Data yang diperoleh dari hasil pretest dan posttest dianalisis untuk mengetahui peningkatan hasil belajar.  Besarnya peningkatan sebelum dan sesudah pembelajaran dihitung dengan rumus gain ternormalisasi. Pembelajaran dapat dikatakan berhasil dilihat dari hasil belajar 4 siswa field independent yang berada pada kategori sangat tinggi, serta peningkatan hasil belajar siswa yang dihitung dengan rumus N-gain yaitu 0,843 atau berada pada kategori tinggi.

Abstract

Problems that are represented visually can develop students' relational and logical understanding. Relational and logical understanding in geometry learning can reinforce certain relationships and develop cognitive functions, such as knowledge construction. In the process of constructing knowledge and constructing problem solving requires students' thinking processes. This study aims to describe students' thinking processes in solving problems that are represented visually. The thought process is based on reflective abstraction. The type of research that is appropriate to achieve these objectives is qualitative. The research subjects are 4 students who have studied the material of flat shapes. The results showed that the concepts represented visually could inspire various ideas in solving problems. In solving problems, the thinking process based on reflective abstraction depends on the history of the solver's knowledge. The mental mechanisms that occur when solving problems with visual representations are interiorization, coordination and encapsulation. Concepts presented using visual representations can increase in-depth understanding, but can also be a source of misconceptions for students. Error answers obtained are the result of misconceptions about concepts/information that have been interiorized into concepts presented using visual representations.

Abstract

This study investigates the effectiveness of creative mathematical reasoning in improving students' numeracy literacy within the framework of the Independent Learning Curriculum. Numeracy literacy is a crucial competency that enables learners to comprehend and address real-world problems using mathematical concepts and skills.  The Merdeka Learning Curriculum provides space for innovative approaches in learning, including the application of creative mathematical reasoning to improve students' numeracy literacy skills. Using a quantitative quasi-experimental design, the study involved junior high school students divided into two groups: an experimental group and a control group. The findings revealed that the experimental group achieved a higher average score (M = 78.9; SD = 10.53) compared to the control group (M = 67.8; SD = 5.30). Statistical analysis using paired and independent t-tests confirmed a significant improvement in the performance of the experimental group (p < 0.05). The results demonstrate that creative mathematical reasoning significantly enhances students' comprehension, critical thinking, and problem-solving skills. The study concludes that integrating creativity-based reasoning strategies is aligned with the Independent Learning Curriculum and offers valuable guidance for teachers to design more innovative, student-centered math learning experiences.
