“教学做合一”是中国教育家陶行知先生的教学理论,这个理论为我们的数学课堂指明了方向。在课堂教学中,教师要始终尊重学生的主体地位,要引导学生积极主动的学习,把课堂还给学生。同时要注意数学课堂教学的实践性,动手动脑中快乐的学习新知识。教师和学生是两个辩证又统一的个体,学生是独立的个体,同时学生又是学习的根本,教师的一切教学必须围绕学生的学进行,但又不是教师的包办,教师应是学生学习的组织者,引导者。 “Teaching to do one ” is the teaching theory of Chinese educator Tao Xingzhi, this theory points out the direction for our mathematics classroom. In classroom teaching, teachers should always respect the students’ dominant position, guide the students to actively study, and return the class to the students. At the same time pay attention to the practicality of mathematics classroom teaching, hands-on brain happy learning new knowledge. Teachers and students are two dialectical and unified individuals, students are independent individuals, while students are the fundamental learning, all teachers must focus on student learning, but not teachers, teachers should be students learning Organizer, guide.
