一、幽默在传授知识中的作用1.幽默可以使抽象的问题形象化,攻破难点,化难为易例如在高一上学期讲授函数时,许多学生对函数的解析式y=f(x)不太理解,于是我便对学生举了一个例子:在一个组装手机的公司里,原材料经过流水线才能组装为一个手机,那么对应法则f就是这一条流水线,它规定了每一步该干什么,x是原材料,经过对应法则的作用,生产出来的产品。即是函数值y。例如函数,即对每一个输入的x,先取其平方,然后加上x的二倍,出来的即是其函数值f(x)。又比如许多学生对根的存在性定理总是不理解。于是我也给学生举了这么个例子:现在你拿着一根绳子(当然是连续不断
First, the role of humor in imparting knowledge 1. Humor can abstract the problem of visualization, breaking the difficult, difficult for easy For example, in the first semester of teaching function, many students on the function of the analytical y = f (x) is not Too understanding, so I gave an example to the students: In a cell phone assembly company, the assembly line of raw materials can be assembled into a mobile phone, then the corresponding law f is the pipeline, which sets out what to do at each step, x is the raw material , After the corresponding law, the products produced. That is the function value y. For example, the function, that is, for each input x, take its square, and then add x twice, that is, its function value f (x). Another example is that many students always do not understand the existence theorem of roots. So I gave the students cited such an example: Now you are holding a rope (of course, continuous
