当前,中学数学教学仍受着“应试教育”的严重影响,这样的教学学生学得苦,教师教得累,最终势必导致重知识,轻能力,高耗低效的后果。而提高课堂教学效率的重要一环就是数学课的引入。俗话说:万事开头难。一堂好的数学课,就务必有一个引人入胜的引入。那么在数学课上用怎样的引入才能牢牢抓住学生的心,让他们有活跃的思想,积极参与的冲动,从而提高一堂课的效率。
At present, mathematics teaching in middle schools is still heavily influenced by “exam-oriented education”. Such teaching students learn hard and teachers are tired. In the end, it is bound to result in heavy knowledge, light capacity, and high consumption and low efficiency. An important part of improving classroom teaching efficiency is the introduction of mathematics lessons. As the saying goes: Everything is difficult at the beginning. For a good math lesson, there must be a fascinating introduction. Then what kind of introduction in mathematics class can firmly grasp the students’ hearts and let them have active thoughts and impulses for active participation, so as to improve the efficiency of a class.
