(一)式题的检验算术习题中,对式题的演算占了不少的分量,而式题演算的正确与否,对应用题的演算又影响特深,所以我们对此也应特别重视。式题演算的检验方法,颇为繁杂。下列各种,教师应在适当的场合,随时介绍给学生,至于原理方面,则应斟酌学生的程度进行解释,此间所述有许多只是供教师参考的。 (1) Tests of formula questions In mathematics exercises, the calculus of formula questions accounts for a lot of weight, and the correctness of the formula calculus affects the calculus of the applied questions. Therefore, we should pay special attention to this problem. . The test method of formula calculus is rather complicated. The following types of teachers should be introduced to students at any time on appropriate occasions. As for the principle, the explanation should be based on the degree of students. Many of these are just for teachers’ reference.
