数列求和是高中数学教学中的难点、重点,属于思维开发类的题目。在教学过程中,由于其数列安排的繁琐、复杂,使学生一看容易产生“懵”的感觉,总是觉得无处下手,其实数列之间都有一定的关系,关键在于教师要引导学生分析、讨论其数列之间的关系形式,进而自主解决问题。新课改一直强调课堂教学中学生的主体性作用,作为教师在教学中可以引导学生分析数列关系,然后引导学生拓展思维,分析、讨论数列求和的解题方法。
Summation of numbers is a difficult and important point in high school mathematics teaching, belonging to the topic of thinking development. In the process of teaching, because of its cumbersome and complicated arrangement of numbers, the students always feel that they feel they are nowhere to go. In fact, there is a certain relationship between the numbers. The key lies in that teachers should guide Students analyze and discuss the form of the relationship between the series, and then solve the problem autonomously. The new curriculum reform has always emphasized the subjective role of students in classroom teaching. As a teacher in teaching, students can guide students to analyze the relationship between numbers, and then guide students to expand their thinking and analyze and discuss the solution to the problem of sequence summation.
