在传统小学算术教学体系中,所选取的内容只限于算术这门学科范围,代数知识往往排斥在外。譬如,只有数的等式,没有数的不等式;只有算式,没有代数式;只有正数,没有负数;应用题只用算术解法,不用代数解法等。这种安排是否符合客观情况,是否符合学生认识规律,可以进一步探讨。 In the traditional primary school arithmetic teaching system, the selected content is limited to the scope of arithmetic, algebra knowledge is often excluded. For example, only the number of equations, there is no number of inequalities; only arithmetic, no algebra; only positive, no negative; This arrangement is in line with the objective situation, whether in line with the laws of students can be further explored.
