在3+X的物理教学中,解题是一个重要教学环节,思维与解题密切相关,思维形成的有效途径可通过解题来实现;解题是运用所学知识解决实际问题的初探,它能加深对基本定律、公式和原理的理解,提高分析问题和解决问题的能力,从解题中汲取课本以外的知识具有不可替代的作用。经过几年的反复实践,我现在采用“人人都当小老师”的教学模式开展习题课教学,不但让学生充分复习了课本知识,还能提高学生的探究能力、学习能力和解决问题能力,能够在责任感、合作精神和创新意识等方面得到提高,是突破解题难关的好方法,实施此教学模式从以下几方面进行。
In 3+X physics teaching, problem solving is an important teaching link. Thinking and problem solving are closely related. An effective way of thinking formation can be achieved by solving problems. Problem solving is a preliminary exploration of applying practical knowledge to solve practical problems. Can deepen the understanding of the basic laws, formulas and principles, improve the ability to analyze problems and solve problems, from the problem-solving to acquire knowledge beyond the textbook has an irreplaceable role. After several years of repeated practice, I now use the teaching model of “Everyone is a small teacher” to carry out exercises. This not only allows students to fully review textbook knowledge, but also improves students’ ability to explore, learn, and solve problems. Ability to be improved in terms of sense of responsibility, cooperation spirit, and sense of innovation is a good way to break through difficulties in solving problems. The implementation of this teaching mode is carried out from the following aspects.
