通过多年的实践,认为只有在课前精心准备,课堂上才能发挥自如。首先培养学生的预习、复习习惯,其次教师要从明确教学目标、灵活选择教法、巧设问题情境、精心选择课堂练习四个方面下功夫,激发学生的学习欲望,提高课堂效率。 Through many years of practice, it is believed that only in the pre-class preparation, the class can play well. First of all, it is necessary to cultivate students’ preparation and review habits. Secondly, teachers should make efforts to clarify teaching objectives, select teaching methods flexibly, design problem situations, and carefully select classroom exercises to stimulate students’ desire to learn and improve classroom efficiency.
