教学的成功与否在很大程度上表现在是否培养了学生的数学能力,而数学能力的强弱在很大程度上又表现在学生能否运用所学知识去解决实际问题。因此,在数学教学中,如何使学生“领悟”出数学知识源于生活,又服务于生活,能用数学眼光去观察生活实际,培养解决实际问题的能力,应成为每位数学教师重视的问题。 The success of teaching is to a large extent manifested in whether to cultivate the students’ math ability, and the strength of math ability is largely reflected in whether students can use the knowledge they have learned to solve practical problems. Therefore, in mathematics teaching, how to make students “comprehension ” out of mathematical knowledge from life, but also serve life, can use mathematics to observe the actual life, cultivate the ability to solve practical problems, should become the focus of every mathematics teacher The problem.
