Abstract
In Khulna city, Bangladesh, I developed environmental education materials (flip cards, carta, board game and action plan sheet), including the topics for understanding that waste pickers contribute to circulate the community resources by the separate collection and to conserve the environment, that the community society alleviate waste picker’s social exclusion, and that citizens acquire their capacity of appropriate waste management. This research aims to consider their level of understanding of learning through the environmental education program, targeting 1,690 elementary and 828 secondary school students in the 40 schools in total, which are responsible for the next generation. As a result, it was clarified that more than 80% elementary and secondary school students could understand the contents on the developed environmental education materials, and it was usefulness and necessity according to the comments from teachers and guardians.
