1问题的提出新的课程改革要求培养学生的创新能力和实践能力,使学生主动学习;注重学生认知过程的发生,让学生做课堂的主人.当前,中学物理课堂教学的弊端之一,是忽视认知的发生过程,不适当地扩大认识的整理阶段.即以最短的过程、尽量快的速度授完新课,把概念和规律灌给学生,然后挤出大量时间进行解题训练.这种以“提前判断”为特征的课堂教学结构有如下弊端:(1)忽视新课的引入过程,结果降低了学生的学习兴趣和动机;(2)忽视概念的形成
A new problem in the reform of the curriculum reform requires students to develop innovative ability and practical ability to enable students to take the initiative to learn; focus on students cognitive process, so that students do the classroom master.At present, one of the drawbacks of high school physics classroom teaching is Ignoring the cognitive process, inappropriately broaden the understanding of the finishing stage, that is, the shortest process, as soon as possible to grant a new class, the concept and discipline of the students, and then squeeze out a lot of time to solve the problem training. The classroom teaching structure characterized by “advanced judgment ” has the following disadvantages: (1) Neglecting the introduction of the new course results in reducing the students’ interest in learning and motivation; (2) Ignoring the formation of concepts
