数学教学要着重培养和发展学生的运算能力、处理数据的能力、空间想象能力、逻辑思维能力、数学信息的表达和交流能力,而运算能力则排在其余诸能力之前。可以这么说,数学就是计算,计算能力对于学习数学的重要性极大,但从平时的练习、考查来看,目前初中学生的运算能力薄弱,速度慢,常出差错。因此,在教学中必须加强指导和训练,逐步提高学生的运算能力。下面根据自己多年的教学实践,谈谈教师应该如何提高学生的计算能力。
The mathematics teaching should focus on cultivating and developing student’s computing ability, data processing ability, spatial imagination ability, logical thinking ability, mathematical information expression and communication ability, and the computing ability is ranked before other capabilities. It can be said that mathematics is computation. Computational ability is of great importance for learning mathematics. However, judging from the usual practice and examination, junior high school students have weak computing ability, slow speed, and often mistakes. Therefore, it is necessary to strengthen the guidance and training in teaching, and gradually improve the students’ arithmetic ability. According to his own teaching practice for many years, he will talk about how teachers should improve their students’ computing skills.
