新的科学课程标准指出科学学习是以探究为主的学习,亲身经历以探究为主的学习活动是学生学习科学的主要途径,而科学探究的教与学又主要是通过内容的操作来体现的,因而探究内容的选择与优化将直接关系到探究活动效率的高低。本人结合自身的教学实践,谈谈几点看法。 The new science curriculum standard points out that science learning is mainly inquiry-based learning, and learning-by-experience is the main way for students to learn science. Teaching and learning of science inquiry is mainly embodied by the operation of content Therefore, the selection and optimization of inquiry contents will directly affect the efficiency of inquiry activities. I combine their own teaching practice, talk about a few comments.
