I’m very glad to introduce the ecosystem project called 邂蟹农Xie Xie Nong, created by both teachers and students at the end of 2017. After sincere discussion, the Grade 4 students were arranged to do the tasks. In this process, we remembered the original intention, “Do STEAM and let the world be better’. Its purpose was an effort to solve the environmental problems by growing hairy crabs to include learning about waste discharge and pollution. For that, we chose the hairy crab which was quite local and also a popular food, taking the main role in our project. The students learnt the project by PBL, project based learning and our PSP, problem solving program. It’s lucky that we were involved with the Wiseman Educational Company, invited as the brain of our project, the DaHu Aquaculture Company Limited, invited as our technology counselor and the Zhongkehai Recycling Aquaculture System Co., Ltd, invited as the guarantee for our devices. The experts were the advisor for our children and supported the students to do their research, design, practice, conclusion and reflection. This summer, there were lots of volunteers who came to school through the extremely warm temperatures to take care of the baby crabs and hydroponic vegetables. Their parents need to be appreciated too because they also came and enjoyed the project and were the strongest backup for their children. At the beginning of this semester, one student spontaneously made a PowerPoint which concluded his Xie Xie Nong learning journey to share with everyone in his own opinion. Welcome to come, join and connect with his Xie Xie Nong team by accessing and enjoying his PowerPoint. We hope that there are more people who are as kind and diligent, creating such projects and making a novel and interesting world.
