Effectiveness of Cooperative Learning (Theme: Limited Natural Resources) to Increase Intention to Save Energy in Students

Some of the natural disaster occurred caused by people using natural resources unwisely. Before analyzing about that behavior, first will be analyzed is behavioral intention. The purpose of this study was to determine the effectiveness of cooperative learning group investigation type with the theme of “limited natural resources” to improve intention to save energy. The study used an experimental design Post-test-Only Design With Equivalent Groups, involving 66 people, divided into two groups, each 33 in the experimental group and 33 control group. Process experiments were conducted in a way, dividing the experimental group in 5 small groups, having given the matter of limited natural resources, then each group discussion, and sharing ideas with other groups in the jigsaw. The results showed that there are differences in energy-saving behavior intention significantly between the experimental group (KE) and the control group (KK) with t value of 3.192 with 0.002 significance (p <0.05). Differences KE and KK with a positive t value indicates that the energy-saving behavior intention at KE has a higher value than the families who were not given the manipulation. In general score KE and KK if joined at the high category, but if sorted, KE scores at the high category and score KK in middle category.
