课堂教学就是要激发学生的学习兴趣,发展思维,培养能力,使学生既长知识又长智慧。古人曾告诫我们:学习要“知其然”,还应“知其所以然”。“知其然”即是“会”、“知道”,“知其所以然”便是“理解”、“掌握”,也就是明白了“为什么”。只有“知其所以然”才能举一反三,达到灵活运用。实现这一目标,有许多手段和途径。而根据课堂教学实际,适时巧妙地多问几个“为什么”,无疑是一种经济而又高效的方法。 Classroom teaching is to stimulate students’ interest in learning, develop their thinking, and develop their abilities so that students have long knowledge and wisdom. The ancients had warned us that learning should “know what happened” and “know what it is”. “Knowing about it” means “willing” and “knowing.” “Knowing why it’s happening” means “understanding” and “mastering,” that is, understanding why. Only “knowing why it is” can be used as an alternative to achieve flexibility. There are many means and ways to achieve this goal. According to the reality of classroom teaching, it is no doubt an economical and efficient method to timely and ingeniously ask several “why”.
