在初中物理教学中,学生的求知欲望与学习兴趣往往是由疑问引起的。教师组织好课堂提问,是搞好启发式教学,提高教学效果的重要一环。下面结合我们的教学实践,谈谈初中物理课堂提问的几种方法,供参考。一、导入新课的提问。温故而知新,新知识是建筑在旧知识的基础上的,提问要抓住新旧知识之间的联系,遵循认识的规律,用已知的钥匙打开未知的锁。例如,在讲“变阻器”一节课前,教师可提出如下问题:1.舞台上灯光亮度的调节是改变电流大小引起的,用哪些方
In junior high school physics teaching, students’ desire for knowledge and interest in learning are often caused by questions. Teachers’ well-organized questions in class are an important part of doing a good job of heuristic teaching and improving teaching effectiveness. The following combination of our teaching practice, talk about the junior middle school physics class questions several methods for reference. First, introduce new class questions. To learn new things in time, new knowledge is based on old knowledge. Ask questions to grasp the connections between old and new knowledge, follow the rules of understanding, and use unknown keys to unlock unknown locks. For example, before the lecture on “varistors”, the teacher may ask the following questions: 1. The adjustment of the brightness of the lights on the stage is caused by changing the size of the current.
