听了各类学校的许多公开课(示范课、研究课、探究课和基础课、拓展课等),总体感觉不错,但也存在一种倾向或现象,即一些教师上课时对物理知识的表述有点绝对化.严格地讲,这属于科学性问题,至少是不妥当的.教师的话语权,还会让这样的表述及思想产生不良的后果.从进一步提升教育教 After listening to many open classes (demonstration classes, research courses, inquiry and basic courses, and extension classes) in various schools, the overall feeling was good, but there was also a tendency or phenomenon that some teachers expressed a bit of physics knowledge in class. Absolutely speaking, this is a scientific issue, at least not appropriate. Teachers’ right to speak will also cause such statements and ideas to have negative consequences.
