在高中数学的教学中,等差数列作为有通项公式而且应用很广泛的数列之一来说,对整个高中数学的教学有着很重要的作用.而数学学习的很重要的一点就在于应用.如何使学生熟练掌握和使用等差数列求和的公式去解决学习中和生活中所遇到的问题,对于培养学生的数学能力有着举足轻重的作用.在这方面,教师要对学生施以恰当的引导,培养学生的数理逻辑能力,养成用数学科学角度思考问题的习惯,最终使学生能够独立自主地去解决相应的问题.但是说起来容易做起来难,在实际的教学活动中,学生往往在处理等差数列求和问题的时候面临诸多困难,不能很好地运用自己所学的知识去解决实际
In the teaching of high school mathematics, the arithmetic progression is very important for the teaching of high school mathematics as one of a series of general formulas and widely used, and it is very important to apply mathematics learning. How to make students mastery and use equations such as sum-of-difference columns to solve the problems encountered in learning and in life plays a decisive role in cultivating students’ mathematical abilities.In this aspect, teachers should impose appropriate Guide and cultivate students’ ability of mathematical logic and develop the habit of thinking about the problem from the perspective of mathematical science, and finally enable the students to solve the corresponding problems independently.However, it is easy to say that it is hard to say that in the actual teaching activities, When dealing with the arithmetic progression of numbers, we face many difficulties and can not properly use what we have learned to solve the problem
