The Conceptual change of human respiratory system through POE-Based Learning

Abstract

Study to analyse the effect of Predict-Observe-Explain (POE)-based learning to the conceptual change of high school students on human respiratory system concept has been done. This study was a weak experimental with one group pre-test and post-test design. The data were obtained by a pencil and paper test in the form of reasonable-multiple choice with two tiered test items. The data were analysed by mean of difference test between pre-test and post-test scores. The finding of study shows that a significant change in the percentage of students scientific conception between pre-test and post-test. The result shows that the increase of student conceptual change with N-gain average is 0.52 (moderate category). In addition, the result also shows that a pattern of student conceptual changes that positive changed is 44.3%, positive survival is 20.5%, negative change is 11%, and negative survival is 24.2% respectively. Based on result shows that POE-based learning strategy can be developed in high school to support students in resolving conceptual change of scientific concept.
