在小学,计算教学始终贯穿于数学教学的全过程,可见计算教学的重要性。教师对于计算的教学也是非常重视的,但是却总是在强调正确率和错误率,忽略的计算原理。正确的运算必须建立在透彻地理解算理的基础上,学生的头脑中算理清楚,法则记得牢固,做计算题时,就可以有条不紊的进行。笔者认为,计算原理的教学的关键在于计算的情境,本文笔者结合具体的教学实例,浅谈在情境中进行计算教学。
In primary school, teaching of calculation runs through the entire process of mathematics teaching, showing the importance of calculating teaching. Teachers also attach great importance to the teaching of calculation, but always emphasize the correctness and error rate, ignoring the calculation principle. The correct operation must be based on a thorough understanding of the basis of the calculation. The students’ minds should be clearly defined, the laws should be kept firmly in mind, and the calculation should be carried out orderly. The author believes that the calculation of the principle of teaching lies in the calculation of the situation, the author of this article with specific teaching examples, to talk about computing in the context of teaching.
