高效课堂是指在教学过程中,教师对学生进行积极正确的引导,用尽可能少的时间获取最大教学效益的教学活动。如何打造高效的数学课堂是我们数学教师必须思考和解决的问题,根据多年的教学实践,笔者认为可从以下几方面入手。一、课前必要学习任务的布置高效课堂要求我们在课堂上取得最好的教学效果。因此,课前必要学习任务的布置很关键。比如在学习“截一个立体图形”时,需要让学生们了解正方体的截面,笔者让学生课前每人用萝卜或土豆切上4个小正方体,课堂上
Efficient class refers to the teacher’s active and correct guidance to students in the teaching process, and uses the least possible time to obtain teaching activities that maximize teaching effectiveness. How to create an efficient mathematics classroom is a problem that we mathematics teachers must think about and solve. According to many years of teaching practice, the author believes that the following aspects can be started. I. Arrangement of necessary learning tasks before class Effective classroom requires us to achieve the best teaching effect in class. Therefore, the arrangement of necessary learning tasks before the class is critical. For example, when learning to “cut a three-dimensional figure,” students are required to understand the cross-section of the cube. The author asks students to cut four small cubes with radishes or potatoes before class, in class.
