当前,随着21世纪核心素养研究的日益升温,教育天平已逐渐向学生的“学”倾斜。众所周知,学校的“使命就是要将这些人类积累的经验,经过选择、组织加工后由教育者传递给受教育者,从而将人类知识转化为个体知识”~([1]),所以学校教师必须要围绕知识来设计教学,而教师只是学生学习的指导者、引路者,学生才是建构知识体系的主体。因此,学生的学习成为我们教学研究的关注点,“以学定教”的理念应运而生。 At present, with the increasing research on core literacy in the 21st century, the education balance has gradually been tilted toward students’ learning. It is well-known that the mission of the school is to transform the experience accumulated by these human beings into educated people through selection, organization and processing, and then to transfer human knowledge into individual knowledge. “Therefore, the school Teachers must design teaching around knowledge, and teachers are only the mentors, guides and students of students’ learning, which is the main body to construct knowledge system. Therefore, the study of students has become the focus of our teaching and research, and the idea of ​​”learning by teaching" came into being.
