摘    要 二十一世纪以来，科学技术发展愈来愈迅猛，为社会带来诸多有益变革。然而，一系列严重阻碍社会可持续发展的负面问题亦显现出来。科技是增强综合国力的最强因素，科学素质成为二十一世纪公民必不可少的一项基本素质。而我国公民整体科学素质与发达国家仍有差距，教育亦存在问题。基于此，教育部启动了课程改革。而在国外，一组科学教育专家召开了国际研讨会，提出了以大概念的理念进行科学教育。

本论文正是基于大概念的理念，对我国《初中科学课程标准（2011版）》以及现行主要科学教材中的浙教版进行分析，并与人教版物理教材进行对比，通过对 “能量及能量转化与守恒”部分内容的具体分析，得出看法。90236

实验内容应注意与日常生活实际相联系以激发学生对探索周围的兴趣，或联系其他知识点以帮助学生形成知识体系框架。将科学知识以尽量明显直观的形式展现给学生，使学生参与探究的过程，锻炼学生的各项能力，培养学生的科学素养。

Abstract The 21st century, science and technology development more and more rapidly, bring a lot of useful changes for the society。 However, a series of seriously hinder the sustainable development of the society negative problems also emerge。 Science and technology is to enhance the comprehensive national strength of the strongest factors, quality has become a 21st century citizen essential basic quality。 And our citizens as a whole there is still a gap with the developed country, scientific quality education also has a problem。 Based on this, the ministry of education launched the curriculum reform。 Abroad, a group of international symposium on science and education experts convened, put forward with the big ideas of the concept of scientific education。

This paper is based on the concept of the concept of big to our country the junior middle school science curriculum standards (2011 edition), and to analyze the zhejiang version of the current main science teaching material, and compared with o 'clock physical material, through the "energy and energy conversion and conservation" part of the concrete analysis, concluded that view。

Experiment content associated with the actual daily life should be paid attention to in order to stimulate students interest in exploring around, or connect with other knowledge in order to help students form a knowledge system framework。 The scientific knowledge in the form of a visible as far as possible to students, make students participate in the process of exploring, exercise the ability of students, cultivate the students' scientific literacy。
