学生借助自学案,对新知识首先进行自主探究。自学案的设计要具备很好的指导性、实用性。教师引导学生通过自学反馈、课堂交流,解决学生在自主学习中遇到的困惑。在小学数学课堂教学中教师应设计适量有层次性的练习题,留给学生更多的时间自主解决问题,从而增强课堂学习效果。 Students with self-learning case, the first independent study of new knowledge. Self-learning design should have good guidance and practicality. Teachers guide students through self-feedback, classroom exchange, to solve the confusion students encounter in their own learning. In primary mathematics classroom teaching teachers should design the appropriate level of exercises, leaving students more time to solve problems, thereby enhancing the effectiveness of classroom learning.
