物理是一门以观察、实验为基础的学科。在新课标中,探究实验的比重偏大,而对教学设备不足的普通中学,按现时教学大纲的课时安排,要落实好探究实验是很不容易的。作为普通中学的教师,应如何解决这一矛盾呢?笔者的做法是:重要的物理规律、定律的建立,由学生通过实验探究来完成,而课堂演示实验的分量安排则相对大些。这就需要教师解决好下列问题:如何在课堂上提高演示实验的可见度?如何调动学生积极参与实验活动?下面就上述问题谈我的一些有效做法。
Physics is a discipline based on observation and experiment. In the new curriculum standard, the proportion of inquiry experiments is too large. For ordinary secondary schools with insufficient teaching facilities, it is not easy to carry out inquiry experiments according to the current school time schedule. As an ordinary middle school teacher, how to solve this contradiction? The author’s approach is: the establishment of important laws of physics, laws, to be completed by the students through experimental exploration, and the components of the classroom demonstration experiment is relatively large. This requires teachers to solve the following questions: How to improve the visibility of demonstration experiments in class? How to mobilize students to actively participate in experimental activities? Here are some effective practices on the above issues.
