Teaching Study Of Important Knowledge Points In Physics Optics In High School

Physics Optics plays a very critical role to the development of physics and mordern science and technology. Knowledge points such as interference、diffraction polarization and photoeffect of light in Physics Optics in high school, which are important contents all the time, always keep the important position in the basic teaching reform every time.First, the text is guided by the teaching theory of the physical concepts and laws. The important knowledge points such as interference、diffraction、polarization and photoeffect of light in Physics Optics in high school are anylized from the aspects of concept discrimination, experimental study, application study and puzzling question and so on. Then, by questionnaire survey, pre-concept before learning, mastering after learning and learning difficulty from students and teaching from teachers about these important points have been obtained. Finally, teaching and learning suggestions suitable for our school are proposed to be the critical reference in teaching of Physics Optics in high school.
