Abstract
The study to determine effect of Predict-Observe-Explain (POE)-based learning on the conceptual change of high school students on the human respiratory system has been done. This study is a weak experimental of one group pretest and posttest design. The data were obtained by a pencil and paper test in the form of reasonable-multiple choice questions. The data were analysed by mean of difference test between pretest and posttest scores. Based on study findings shows that a significant change in the percentage of scientific conceptions of students between pretest and posttest. The result shows that there is an increase conceptual change of student with average of N-gain is 0.52 (moderate category). In addition, the results also shows that a pattern of conceptual change that positive change 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 model can be developed in senior high school to support students in overcoming conceptual change of scientific concept.
