一、案例背景当前,减负增效已成为广大一线教师关注的焦点,如何真正落实好减负增效,在小学数学学科,作为提高学生学习数学效率的课前预习活动越来越被数学教师所采用。课前预习的好,学生带着预习后的问题进入课堂,就会有一种想学、想问、想练的良好学习心理状态,新知的重难点就会在教学的互动中被学生所领悟,能有效激发学生自主探索和求知的欲望。
First, the background of the case At present, the burden on reducing efficiency has become the focus of front-line teachers, how to really implement the burden reduction and efficiency, in primary school mathematics, mathematics teachers as a way to improve students’ learning efficiency is more and more used by mathematics teachers . Good pre-class preview, students with the problem after the preview into the classroom, there will be a want to learn, want to ask, want to practice a good state of mind, the new knowledge of the difficulties and difficulties will be in the teaching of the interaction of students are comprehend, Can effectively stimulate students’ desire for self-exploration and knowledge.
