作为一名初中数学老师,在小学一年的支教过程中,我了解到小学生和初中生学习活动的不同。稍做比较:从小学到初中,学习内容明显加深,由于数的扩充引入了负数、有理数、相反数、绝对值等新的概念,运算关系也由原来的四则运算引入了乘方、开方运算。在数学学习方法上也有一定的差异,小学阶段科目少,内容浅,而中学的学习科目的增加,内容加深,使之顾暇不及,更有时间上的紧迫,这些都是客观因素。小学教师讲得细,练 As a middle school mathematics teacher, I learned about the difference in primary and junior high school students’ learning activities during their one-year primary education. A little comparison: From elementary to junior high school, the learning content is obviously deepened. Due to the expansion of numbers, new concepts such as negative numbers, rational numbers, opposite numbers, and absolute values ​​are introduced. The relations of operations are also introduced into the square by the original four operations. . There are also some differences in math learning methods. There are few subjects in primary school and shallow subjects. However, the increase of secondary school subjects and the deepening of their learning subjects make it more time-consuming and time-consuming, all of which are objective factors. Primary school teachers speak fine, practice
