一、教学案例这节课的主要目的就是学生和老师一起探究棋盘摆放规律,探究等差数列前n项和公式。教学策略是启发和探究式教学相结合,讲练结合。主要方法是把班级分为6个小组,每组8人,每组发一盘围棋,小组协作,运用高斯思想,共同动手摆棋子、找规律。我首次尝试这种方式教学是在高一(1)班,主要步骤如下: First, the teaching case The main purpose of this lesson is that students and teachers to explore the law of placing the checkerboard, to explore the difference before the n columns and formulas. Teaching strategies are inspired by the combination of inquiry teaching and teaching. The main method is to divide the class into 6 groups of 8 people, each group sends a go game. The group cooperates and uses the Gauss idea to jointly put the chess pieces and find the law. The first time I tried this method of teaching was in high one (1) class, the main steps are as follows:
