学习数学较理想的状态是能够从有限的例题出发举一反三,同时让学生体验自行编题的乐趣,培养学生的创新意识和学习能力,真正达到“授人以渔”的目的.这里笔者以在上课时讲授的一道例题为例,谈谈如何让学生尝试发现问题和解决问题在选修2-1第2章的复习课上,我举了如下例题:例1:已知过抛物线y2=2px(p>0)焦点F的直线l交抛物线于M,N两点,B(-p,0),求证:直线BM与直线BN的斜率互为相
Learning mathematics ideal state is able to start from a limited number of examples to learn from each other, while allowing students to experience the fun of self-programming, develop students’ sense of innovation and learning ability, and truly achieve An Example Taught During Class Talking About How to Have Students Try to Discover and Solve Problems In the elective 2-1 Chapter 2 review class, I cite the following example: Example 1: Known Parabola y2 = 2px (p> 0) the focus of the straight line l parabolic parabola at M, N two points, B (-p, 0), verify: the slope of the straight line BM and the straight line BN each other
