一节精彩的数学课堂通常需要一个完美的课堂引入,恰当的导入环节可以充分调动学生学习数学知识的积极性,激发学生的求知欲从而提升学生对数学知识的学习兴趣,让学生积极主动的参与到数学知识的学习中。同时可以集中学生注意力使其紧跟数学教师课堂讲课节奏,促进学生数学学习效率的提升。本文就从初中数学的角度出发对课堂引入的有效应用进行一些分析。 A wonderful mathematics classroom usually requires a perfect introduction of the classroom, the appropriate introduction of the part can fully mobilize the enthusiasm of students to learn mathematical knowledge, stimulate students ’curiosity to enhance students’ interest in mathematical knowledge, so that students take the initiative to participate Mathematics knowledge learning. At the same time, students ’attention can be concentrated to keep up with the rhythm of classroom lectures by mathematics teachers and promote the improvement of students’ math learning efficiency. This article from the junior high school mathematics point of view to introduce the effective application of the class some analysis.
