The Effect of Argumentation-Based Inquiry Approach on Students' Academic Achievement and Analytical Thinking Skills

This study aimed to investigate the effects of the argumentation-based inquiry (ABI) approach on the analytical thinking skills of seventh-grade students using a mixed method. It was conducted in a secondary school in the Black Sea region of Turkey with seventh-grade students from two classes during the fall semester of the 2021–2022 academic year.  The findings show that the application of the ABI approach in science classes is effective on the academic achievement of students.  According to the analytical thinking test findings, a significant difference was found in favor of the experimental group in the post-test. The evaluation of the quantitative and qualitative findings revealed that the ABI approach used in science lessons had improved the analytical thinking skills of the experimental group students.
