Developing Critical Thinking Skills Using the Predict-Observe-Explain Strategy Combined with Model-Based Learning on the Digestive System for Grade 6 Students

Abstract

This study aimed to 1) determine the efficiency of lesson plans using the Predict-Observe-Explain (POE) strategy combined with model-based learning on the topic of the digestive system for Grade 6 students, against the 75/75 efficiency criterion, 2) compare students' critical thinking skills before and after instruction, 3) compare students' learning achievement before and after instruction and 4) examine students' satisfaction toward learning management using the POE strategy combined with model-based learning. The sample consisted of 10 Grade 6 students from Ban Non Noi School, selected through purposive sampling. Research instruments included lesson plans, a critical thinking skills test, a learning achievement test, and a satisfaction assessment form. The results revealed that 1) the lesson plans using the POE strategy combined with model-based learning on the digestive system achieved an efficiency of 89.50/83.00, exceeding the specified 75/75 criterion, 2) students' critical thinking skills after instruction were significantly higher than before instruction at the .05 level of statistical significance, 3) students' learning achievement after instruction was significantly higher than before instruction at the .05 level of statistical significance and 4) students' overall satisfaction toward the POE strategy combined with model-based learning was at the highest level (M = 4.77, S.D. = 0.17).
