在实践教学过程中,我们发现越简单的数学题目,学生的计算正确率就越低,很多教师都把造成这种现象的原因归结为马虎粗心,其实这是不科学的。学生计算能力弱是由学习基础、计算习惯、心理因素、课堂教学等因素综合导致的,是欠缺数学素养的表现。下面结合教学实践,对培养和提升初中生的运算能力提出几点策略: In practice teaching, we found that the simpler mathematics topics, the students calculate the lower the correct rate, many teachers are attributed to cause this phenomenon can be attributed to careless careless, in fact, this is unscientific. The weak ability of students’ calculation is caused by the combination of learning foundation, calculating habit, psychological factors and classroom teaching, which is a sign of the lack of mathematical literacy. The following combination of teaching practice, to raise and improve the computing power of junior high school students put forward some strategies:
