Abstract

The ability to think critically about students in Indonesia is relatively low, this is evidenced in the results of the 2018 PISA research survey. Selection of methods is needed to overcome these problems. This study aims to determine the effect of using the Brainstorming method on students' critical thinking skills in fifth grade mathematics at SD Inpres Bumi Sagu. The research design used the One-Group Pretest-Posttest Design with a sample of 18 students in class V B at SD Inpres Bumi Sagu. Data collection used multiple choice questions which included indicators of critical thinking with data analysis using the Paired Sample T-test assisted by the SPSS version 16 program. The results showed an increase in the indicators of knowing and solving problems 47.22; indicators analyze 33.33; indicators evaluate 30.55; and the indicators conclude 18.51. Based on the results of the t-test using the Paired Sample T-test, a sig. (2-tailed) value of 0.000 < 0.05 was obtained. Then the Ha hypothesis is accepted and Ho is rejected, meaning that the brainstorming method in mathematics subject matter of geometric shapes has an effect on the critical thinking skills of fifth grade students of SD Inpres Bumi Sagu.

Abstract

Developing students’ scientific reasoning and argumentation skills is essential for achieving meaningful learning in physics, as these competencies are fundamental to scientific literacy and higher-order thinking. Nevertheless, physics instruction in many secondary classrooms still prioritizes procedural problem solving, providing limited opportunities for students to engage in reasoning and scientific discourse. This condition highlights the urgent need for instructional models that explicitly integrate inquiry and argumentation into learning. This study examined the effect of the Argument-Driven Inquiry (ADI) model on students’ scientific reasoning and argumentation skills using a mixed-method quasi-experimental design with a non-equivalent pretest–posttest control group. The participants were 72 eleventh-grade science students from a public senior high school in Central Sulawesi, Indonesia, divided into an experimental (ADI) and a control (conventional instruction) group. Data were collected using validated reasoning and argumentation instruments and analyzed through normalized gain, ANCOVA, and discourse analysis. The results showed that students in the ADI group achieved higher improvements in scientific reasoning (N-gain = 0.66, high) and argumentation quality (N-gain = 0.72, high) than those in the control group. Discourse analysis further revealed more frequent construction of claims, use of evidence, and rebuttals among ADI students, indicating deeper epistemic engagement. In conclusion, this study provides novel empirical evidence that ADI effectively strengthens reasoning-based physics learning by simultaneously enhancing students’ scientific reasoning and argumentation, offering a robust pedagogical contribution for fostering higher-order thinking in secondary science education.
