教学,作为一门艺术,精心设计新课的导入,让学生对一堂课产生良好的第一印象,无疑是这堂课成功的第一步。数学课的导入方法很多,但不管选用什么方法导入,都要有利于激发学生主动参与学习的兴趣和求知的欲望,从而形成学习的期待,产生学习的动机。 Teaching, as an art, well-designed new class introduction, so that students have a good first impression of a class, is undoubtedly the first step in this lesson. There are many ways to import mathematics lessons, but no matter what method you choose to import, you should help to stimulate students' interest in participating actively in learning and the desire to know each other, so as to form a learning expectation and generate motivation for learning.
