新课程标准明确指出:运算能力,它是中学数学三大基本功能之一。运算能力体现了思维能力,反映了一个人的综合数学能力。培养运算能力是一项复杂系统工程,是一项长期而艰巨的任务,教学中要靠长期反复的实践活动,循环反复,螺旋上升。运算能力的培养贯穿于整个中学数学教学的始终,要有计划、有目的、有意识地运用科学的方法进行长期渗透,使学生不断地、经常性地受到启迪,在潜移默化中逐步领悟运算能力的实质,从而提高运算能力。教学中,既
New curriculum standards clearly pointed out: computing power, it is one of the three basic functions of high school mathematics. Computational ability reflects the thinking ability, reflecting a person’s comprehensive mathematical ability. It is a long-term and arduous task to cultivate computing power, which is a complex systematic project. Teaching should rely on long-term and repeated practice, repeated cycles and spiraling. The cultivation of computing power runs through the entire middle school mathematics teaching from beginning to end, and should be planned, purposeful, and consciously using the scientific method for long-term infiltration, so that students can be enlightened continuously and constantly, gradually comprehending the essence of computing power , Thereby enhancing computing power. In teaching, both
