有趣+知识,提高学生数学的兴趣许多时候,老师精心设计了一节课,满腔热忱来到教室,但看见大部分同学都趴在桌子上萎靡不振。如何打破这个尴尬的局面?对于大部分为男生的班级,导入时可这样设计:“同学们,现在NBA比赛正在进行,你们比较关心哪支球队?你们知道吗,数学对于篮球运动的发展也作出了很大贡献,如通过计算投篮弧度的偏差,调整投篮的角度、投篮的力量大小等,来提高投篮的命中率。”而对于男女生比例相当的班级,导入时可这样设计:“同学们,我近来看了一部电影。电影中介绍了一位出色的数学家,讲述了他如何利用数学知识来破解密码的故事。这个密码是由美国设计卖给台湾应用在通讯方面的高级密码,你们知道他是怎样破解的吗?”导入得法,能够引起学生的注意和兴趣,调动他们的积极性,为完成教学任务创造条件。小小的技巧、简短有趣的开场白,犹如给学生注射了一柱兴奋剂,让他们从疲倦中走出来,虽然有点麻烦,但可以拉近老师与学 Interesting + knowledge to improve students’ interest in math Many times, the teacher carefully designed a class and came to the classroom full of enthusiasm, but saw most of the classmates lying on the table. How to break this awkward situation? For the majority of boys in the class, the introduction can be such a design: “Classmates, NBA games are now under way, which team are you more concerned about? You know, mathematics for the development of basketball Also made a great contribution, such as by calculating the deviation of the shooting arc, adjust the shooting angle, shot size and so on, to improve the shooting rate. ”And for boys and girls a considerable proportion of the class, can be imported such design: “Classmates, I recently watched a movie that introduced an excellent mathematician who described how he used mathematical knowledge to crack the story of a password that was sold by the United States to Taiwan for use in communications You know how he cracked it? ”Imported law, can arouse the students’ attention and interest, to mobilize their enthusiasm, to create the conditions for the completion of teaching tasks. Little tricks, short and interesting opening remarks, as if to inject a column of stimulants to students, so that they come out of fatigue, although a bit cumbersome, but can narrow the teacher and learn
