在传统的高中数学的课堂教学中,以教师讲授、学生被动接受为主,主要通过概念教学,对公式的强化记忆,然后做大量习题,对不同类型习题的解题方法进行强化训练以达到应试的目的.但是这样的课堂教学没有突出学生的主体地位,学生不断地接受和被迫记忆,效果有限,有数据指出,学生自主思考总结出来的结论经过24 h以后遗忘率仅为25%~30%,所以有效地构建课堂教学,提高学生的参与程度,显得十分必要. In the traditional high school mathematics classroom teaching, teaching by teachers, students accept mainly passive, mainly through the concept of teaching, strengthening the formula of memory, and then do a lot of exercises, different types of exercises to solve the problem of intensive training to achieve the test However, this class of teaching did not highlight the dominant position of students, students continue to accept and forced to memory, the effect is limited, some data indicate that the students concluded that the conclusions of independent thinking after 24 h forgotten rate of only 25% to 30 %, So effectively construct classroom teaching, improve student participation, it is very necessary.
