The effect of science writing heuristic approach with multiple representation in improving students’critical thinking skills

This study aims at investigating the effect of the integration of multiple auditory representation into heuristic approach on students’ critical thinking skills. A quasi-experimental method with Pretest-Posttest Control Group design which involved in 24 participants in the experimental and control classes was applied to answer the research problem. An essay test was used to collect the data, while the paired sample T test was carried out to evaluate the impact of the implemented approach on students’ thinking skills. Significant improvement of critical thinking skills was observed for students who have applied a heuristic approach with multiple representative hearing than those students who have experienced a heuristic approach without multiple representations. The large category of effect size (1.1), suggesting that the learning process in the experimental group was more effective compared to those Learning in the control class. The current results show that the fusion of multiple auditory representation into heuristic approach provide an alternative learning approach for enhancing students’ critical thinking skills.
