在数学教学中我发现了这样一个问题,学生能够轻松算出7+8=15,然而当我以解决问题方式提问“湖面上有两艘船,一艘船上坐了7个人,另一艘船上坐了8个人,两艘船上一共有多少人?”有一部分学生解答为“2+7+8=17”中出现的数字都加在了一起。我们发现:在小学数学教学中,我们过于重视数学知识的教授,而忽略了数学知识在实际生活中的运用,学生单纯地学会了数字的加减,在实际的解决问题中却出现了错误,一方面可能由于读题的不慎导致,另一方面就是知识与生活实际的脱节。
I found a problem in math teaching where students could easily calculate 7 + 8 = 15, but when I asked questions to solve the problem, “There are two boats on the lake, seven people on one boat and seven people on the other. Sitting eight people, a total number of people on both ships? ”“ Some students answer the number ”2 + 7 + 8 = 17" are added together. We find that in elementary mathematics teaching, we place too much emphasis on professor of mathematics knowledge, ignoring the application of mathematical knowledge in real life. Students simply learn the addition and subtraction of numbers, but mistakes have been made in solving practical problems. On the one hand may be due to inadvertent reading questions lead, on the other hand is the actual disconnect between knowledge and life.
