九年义务教育物理教学大纲明确指出:“初中物理教学要以观察、实验为基础。它能够使学生对物理事实获得具体的、明确的认识。这种认识是理解概念和规律的必要基础……要大力加强演示和学生实验。”新大纲对演示实验给于高度的重视与强调。 The syllabus for ninth-year compulsory education physics clearly states: “The physics teaching in junior high schools should be based on observation and experimentation. It can enable students to obtain a concrete and clear understanding of physical facts. This understanding is the necessary basis for understanding concepts and laws... It is necessary to strengthen the demonstration and student experiments.” The new outline places a high degree of emphasis and emphasis on demonstration experiments.
