实验是进行自然科学教学的重要手段。物理教师应尽量让学生能在课堂上观察到所研究的物理现象,从而分析所见现象的规律,并把它上升为理论,进而说明这种理论对于实践的指导意义。在进行高中物理“光电效应”内容的教学时,由于原有教学仪器的演示效果不够理想,教师总感到缺少一个较好的光电效应演示仪器。在这种情况下,我利用光电管的灵敏的光电效应,配 Experiment is an important means of teaching natural sciences. Physics teachers should try their best to observe the physical phenomena studied in the classroom so as to analyze the law of the phenomenon and raise it as a theory to explain the guiding significance of this theory to practice. In the teaching of the physics content of “photoelectric effect” in senior high school, teachers often feel that there is a lack of a good demonstration instrument of photoelectric effect due to the unsatisfactory demonstration effect of the original teaching instrument. In this case, I use the photoelectric photoelectric sensor sensitivity, with
