物理是一门自然科学,其高效教学更是学生高效学习的保证。教师的无效提问、探究学习的无效、知识拓展的无效导致了高中物理教学的低效。有效的课堂提问、有效的情境设计、有效的实验教学,是高中物理教学有效性的保证,值得每一位教师积极探索。 Physics is a natural science, its efficient teaching is the guarantee of efficient learning for students. Invalid questioning by teachers, ineffective inquiry learning, and ineffective knowledge extension lead to the inefficiency of high school physics teaching. Effective classroom questions, effective situational design, and effective experimental teaching are the guarantees of the effectiveness of physics teaching in senior high schools. It is worth every teacher’s active exploration.
