等差数列是最基本、最重要的数列之一,等差数列前n项和公式的推导是需要学生掌握的。作者认为推导等差数列前n项和公式时,可以赋予其生动、鲜活的背景,激发学生的学习兴趣,让学生更容易抓住数学问题的本质特征,体会探索与探究的乐趣。在实际课堂教学中,关注学情,从学生的“最近发展区”出发,引导学生发现问题,探索问题,解决问题,最终使各个层次的学生都得以发展。
The arithmetic progression is one of the most basic and important ones. The derivation of the first n terms and the formulas of the arithmetic progression requires student mastery. The author believes that when deriving the first n terms and formulas of the arithmetic progression, they can be given a vivid and vivid background to stimulate students’ interest in learning and make it easier for students to grasp the essential characteristics of mathematical problems and realize the fun of exploration and exploration. In the actual classroom teaching, we should pay attention to the learning situation and proceed from the students “recent development zone ”, guide the students to discover the problems, explore the problems and solve the problems, finally to enable the students at all levels to develop.
