Abstract

This study aims to describe and analyze the implementation of the BAMAHIR learning model—named after a Banjar word meaning "proficient" or "skilled"—which reflects the model's primary goal of fostering skilled problem-solvers and enhancing mathematical conceptual understanding among fourth-grade students at SDN Kelayan Timur 12 Banjarmasin. The research was motivated by students' low problem-solving abilities and limited conceptual understanding in mathematics, issues stemming from teacher-centered instruction, a lack of variety in learning models, and low student engagement during instruction. The study employed Classroom Action Research (CAR), analyzing data descriptively through quantitative percentages supported by qualitative observations across four sessions. The subjects were 29 fourth-grade students at SDN Kelayan Timur 12 Banjarmasin during the 2025/2026 academic year. Data were collected through observation and tests, then analyzed descriptively using a mixed-methods approach (qualitative and quantitative), including percentage calculations. The results indicate that students' problem-solving proficiency improved from 10.34% in the first session to 93.10% in the fourth session, while conceptual understanding rose from 6.90% to 89.66% over the same period; both metrics exceeded the established success indicator of 80%. These findings demonstrate that the BAMAHIR model contribute in enhances students' problem-solving skills and conceptual understanding in elementary mathematics.

Abstract

Low critical thinking skills and problem-solving abilities are common challenges encountered in elementary school Mathematics learning. This study aims to analyze the improvement of critical thinking skills and problem-solving abilities of third-grade students at SDN Murung Raya 3 Banjarmasin through the implementation of the BALOGO Learning Model an acronym for Problem Based Learning (BA), Learning Oriented Games (LO), and Group Oriented Learning (GO). This study employed a qualitative approach using Classroom Action Research conducted over four meetings with 17 students. The results showed that critical thinking skills improved from 18% in the first meeting to 82% in the fourth, while problem-solving abilities improved from 18% to 88%. These improvements were influenced not only by the model itself, but also by the repetition effect, growing teacher–student rapport, the novelty effect of new instructional media, and the advantages of a small class size of 17 students that enabled intensive mentoring. The findings imply the need for sustained integration of problem-based, game-based, and cooperative learning approaches in elementary Mathematics instruction.
