从对科学的全面认识出发,揭示科学的本质属性,并据此导引出科学素养的内涵。进而在此基础上对全面培养学生科学素养提出立足学生发展的三条教育实施意见。最后通过对科学的探究对象、历史发展与认知规律以及“综合”与“分科”两类课程特点的考察,对中学阶段构建“合—分—合”科学课程体系作了论证。 Starting from a comprehensive understanding of science, revealing the essential nature of science leads to the connotation of scientific accomplishment accordingly.
