Introduction of learner-centered environmental education for sustainable development of developing countries and improvement by lesson study

在南非姆普马兰加省尝试了以学习者为中心的可持续发展环境教育和课程研究。姆普马兰加的地球科学课面临的挑战是活动的作用和学习者参与的质量。G7对地球科学的研究能力较低。自然科学教师积极接受课堂学习，但在课后座谈会上的讨论比较肤浅。课后会议的新方法有效地加强了讨论。

Introduction of learner-centered environmental education for sustainable development and lesson study were tried in Mpumalanga Province, South Africa. Challenges of earth science lessons in Mpumalanga are role of activities and quality of learners' participation. Scholastic ability of G7 for earth science is low. Teachers of natural science accept lesson study positively but their discussion in post lesson conference is superficial. New methodology of post lesson conference is effective to enhance discussion.
