【摘要】 在21世纪科技飞速发展的时期,知识更新步伐很快,人们理解和接受知识的速度滞后于知识的更新,因此知识可视化作为一门高效率传播和创新知识的学科被广泛研究。目前,可视化在物理教学领域的研究呈现逐年递增的趋势,且主要集中在大学物理的研究,中学物理可视化研究较少,初中力学可视化的研究更是少之又少。笔者在多年的初中物理教学经历中发现,初中力学内容难度较大,教材中缺少直接揭示物理量之间内在联系的可视化图像。利用编程软件开发可视化的力学素材,并合理运用到教学中对揭示力学物理量之间的关系有着重要意义,对促进可视化在物理教学中的应用有积极的影响,对促进物理教学改革有重要的作用。本论文首先对初中物理教学现状进行了阐述,指出了物理教学中存在的问题,并介绍了国内外关于物理可视化研究的现状,通过文献的查阅,论述了可视化的由来,可视化的教学理念及可视化的理论基础,总结出了力学可视化教学具有直观形象易于理解、增加素材拓宽思路、创造虚拟实验环境降低难度、方便学生自主学习等优点。其次,为了培养学生的控制变量、转换、等量代换等物理思维,笔者选用Visual Basic等软件开发了一系列适合初中物理课堂的力学可视化素材,并详细论述了素材的开发背景、如何利用素材解决教学中存在的问题和总结素材的优势。然后,运用实验对照法在涟源市三一学校选取了两个水平一致的班级分别运用可视化教学和传统教学进行实践,通过问卷调查法调查了学生对可视化教学的支持度和教学效果。结果表明,利用可视化素材辅助力学教学可以将物理知识的逻辑推理过程形象生动的展示给学生,便于学生高效率理解知识,掌握物理思维方法以及提高学习积极性。本论文为初中物理进一步开展可视化教学提供一定的参考。最后,总结全文。可视化前景巨大,笔者希望更多的同行投入到其中,不断丰富初中物理可视化的素材,完善相关的研究,找到一种可以使学生高效掌握物理知识的可视化教学模式,促进初中物理教育的发展。更多还原

【Abstract】 In the period of the rapid development of science and technology in the21 st century,the speed of people’s understanding and acceptance of knowledge lags behind the rapid updating of knowledge.Therefore,knowledge visualization,as a subject of efficient dissemination and innovation of knowledge,has been widely studied.Nowadays,more attention has been paid to the application of visualization technology in physics teaching,but such technology is mainly concentrated in university research,and has not been widely promoted to middle school curriculum teaching,even to the physical mechanics courses.Through years of junior high school physics teaching experience,the author found that there is a lack of visual images that directly reveal the relations between physical quantities in the textbook,especially for the hardest content of mechanics.Using programming software to develop visual mechanics materials and apply them to teaching is beneficial to intuitively reveal the relationship between mechanical physical quantities,and has a positive influence on promoting the application of visualization in physics teaching.Firstly,this thesis describes the current situation of middle school physics teaching,points out the existing problems in physics teaching,introduces the current scenario of physical visualization research at home and abroad,discusses the origin of visualization,teaching philosophy and theoretical basis,and summarizes the advantages of mechanical content visualization teaching.Secondly,in order to train students’ physical thinking such as control variables,transformation and equivalent substitution,the author chooses Visual Basic and other software to develop materials suitable for junior middle school physical mechanics visualization,and discusses the development background of the materials,the application of practical teaching and summarizes its advantages.By comparing two classes of Lianyuan Sany School and using visual teaching and traditional teaching methods,the results show that the visual teaching method can visually show the logical reasoning process of physical knowledge to students,which is beneficial to students’ mastery of knowledge and promotion of learning enthusiasm.This paper provides a reference for the visualization teaching of physics in junior high school.Finally,the thesis is summarized.Visualization has a huge prospect.The author hopes that more peers will devote themselves to it,enrich the materials of junior high school physics visualization,improve relevant research,and find a visualization teaching mode that can enable students to effectively master physics knowledge,so as to promote the development of junior high school physics education.更多还原
