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 finding 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.
