PBL Method under the environmental education in Indonesia analyzing the influence of PBL Method into the knowledge attitude and behavior aspects

The purpose of this research is to clarify the effectiveness of trial of environmental education program based on PBL to teachers and children of elementary schools in multiple cities in Indonesia and to compare before and after program implementation for a certain period of time. From the results of the questionnaire survey conducted for elementary school students, we analyze the relationships among the three items of environmental knowledge, consciousness, and behavior. The surveyed cities are three cities; Bandung, Malang and Batu. At the elementary schools in each city, we implemented the environmental education program prepared by us, in one semester (about 6 months), excluding day off, from November 2015 to June 2016. The effect was verified by conducting questionnaire survey before and after the trial. The questionnaire before the trial was done in October 2015, and the questionnaire after the enforcement was done in August 2016. Although WS being implemented for both the teacher and the students in group A, there was no notable significant difference in terms of awareness and behavior compared to group B and group C. In the item of awareness, Bandung City was significant difference in garbage related questions, and Malang City was significant difference in water related questions.
