3、新课程标准对初中物理知识的要求更高了，对学生掌握物理知识程度要求更灵活了，而初中物理教材中的一些演示实验却没有随之改变，所以初中物理课堂演示实验的改进的研究就很有必要。本文共有六章内容，从四个局部来研究：第一局部，本文研究的背景意义。论文分析了国内外物理演示实验的研究现状，讨论了国内目前关于该问题研究中存在的缺乏，根据物理教学论和新课程理念，确定了本文的研究目标和内容，并提出了本文的研究的思路和方法。第二局部，实验改进的原那么和思路。根据研究内容，确定了初学物理演示实验改进的根本原那么：目的性、科学性、侧重性、实效性、进步性等；提出了演示实验的改进思路。第三局部，改进局部演示实验的实践。这一局
4、部是本文的核心，结合了初中物理力学、电学以及光学局部常见的课堂演示实验改进的案例进行研究，重点介绍了几个典型案例的具体改进，比方“探究二力平衡条件、“瓶吞蛋实验、“探究电流与电压电阻的关系、“平面镜成像特点等，并将改进后的实验方案应用于初中物理教学中，讨论了改进后的效果。第四局部，总结与展望。这局部对本课题研究进行了简要总结：概括了物理演示实验改进的规律，分析了本研究存在的问题和缺乏，拟定了今后的研究方案等。关键词：初中物理；实验教学；演示实验；实验改进；新课程标准 AbstractPhysical experiment teaching is one of the main parts of
