Efektivitas Penggunaan Peta Konsep sebagai Strategi Pembelajaran dan Alat Evaluasi untuk Meningkatkan Penguasaan Konsep Siswa SMP pada Materi Sistem Ekskresi

This research aims to examine the effectiveness of concept maps as learning strategy and as an evaluation tools to assess students' mastery of concepts. The sample in this study was students of grade IX in one of Junior High School in Bandung by using Pretest-Posttest Randomized Control Group Design. The subject learned was excretory system. In experimental group, the students were taught by using concept map strategy, whereas the students in control group were taught by using elaboration strategy that is taking notes. The method used in both classes were lecture and discussion. The effectiveness of concept map as a learning strategy was measured by using N-Gain value. Meanwhile, the effectiveness of concept map as an evaluation tool to assess students' concepts mastery was seen from the relationship between students' score in multiple-choice evaluation and the score of concept map evaluation based on class clasification from multiple choice score: upper class, middle class, and lower class. The result shows that the N-Gain in experimental group (0,73) is greater than N-Gain in control group (0,62). The effectiveness of concept maps as an evaluation tool is quite effective because otherwise the results showed that students' grades multiple-choice acquisition value is directly proportional to students in making a concept map. It can be conclude that concept maps can be used as a learning strategy as well as an evaluation tool
