The Effect of Problem based Learning Model and Concept Map Strategy for Problem Solving and Understanding of the Ecosystem Concept of High School Students

Abstract

This research has purposes to: (1) determine the effect of PBL on problem solving and concept understanding of high school students, (2) determine the effect of Concept Map on problem solving and concept understanding of high school students. This research was a quasiexperimental research. The population in this research were all students of grade X SMA N 6 Yogyakarta. The samples taken for this research were four classes of the X graders out of 7 classes. Testing of differences in the effect of applying various learning models using the one way ANOVA test. These results of the research indicated that 1) the PBL learning model has significant effect on the problem solving and concept understanding of the ecosystem material of high school students; 2) Concept Map has significant effect on the problem solving and concept understanding of ecosystems material of high school students.
