物理学是一门以实验为基础的科学,所以在中学物理教学大纲中明确指出,演示和学生实验在中学物理教学中十分重要。通过演示和学生实验,既能使学生深刻理解概念和规律是怎样在实验的基础上建立起来的,又能掌握一定的实验技能,同时,通过演示使学生对物理现象有更清晰的了解。 Physics is an experiment-based science, so it is clearly stated in the middle school physics syllabus that demonstrations and student experiments are very important in physics teaching in middle schools. Through demonstrations and student experiments, students can gain a deep understanding of how concepts and laws are built on the basis of experiments, and they can also acquire certain experimental skills. At the same time, students can have a clearer understanding of physical phenomena through demonstrations.
