教师在课堂中要善于提问。在每一节课中,有经验的物理教师要精心设计不同层次的形式多样的提问,选择恰当的时机,引导学生去思考、对比、理解与应用。通过师生的交流反馈,发展学生的思维能力,提高课堂教学的效果。有目的地设计提问是课堂教学的重要手段之一,是提高45分钟课堂效果的重要措施。一、创设物理情景,即景提问。初中阶段学生的思维很大程度上属于经验型,他 Teachers should be good at asking questions in the classroom. In each lesson, experienced physics teachers must meticulously design different forms of questions in various forms, select the right time, and guide students to think, contrast, understand, and apply. Through teacher-student exchange feedback, develop students’ thinking ability and improve the effectiveness of classroom teaching. Targeted design questioning is one of the important means of classroom teaching and an important measure to improve the effectiveness of the 45-minute classroom. First, create a physical scene, that is, questions. The thinking of junior high school students is largely empirical. He
