国外科学教育有个说法,叫做“一英寸宽,一英里深”。我的理解是:“一英寸宽”指知识内容宜少而精,“一英里深”指内容要展开,展开了才有可能“深”,才有可能让学生真实、生动地受到科学素养的养成教育。 Foreign science education has a saying, called “one inch wide, a mile deep.” My understanding is: “One inch wide” means the content of knowledge should be less and better, “a mile deep” means that the content should be expanded, and only the possibility of “deep” development can students be truly and vividly accepted by science Develop education.
