In terms of executing the solution, we have created a unit calendar that meets the curriculum requirement in schools in ASEAN countries. Our PBL activity addresses the topic of Plastics in the Environmental Science subject in the Philippines, for Grade 11 students. The topic of Plastics is also taught in the other Southeast Asian countries. At the same time, the usage of the Wix website to host our learning resources utilizes technology so that our solution can be shared to teachers and people who are like-minded in the area. Not only that, our solution can also be made done without technology when it is limited or unavailable. The contents can be printed and made available to interested teachers in the region.
