摘要演示实验是初中物理实验教学的重要形式，在初中物理教学中发挥着重要作用。在新修订的课程标准中反复提到要大力培养学生的物理核心素养，学生的物理核心素养之一就是实验探究，而演示实验正好可以培养学生在实验探究方面要求达到的观察能力，分析论证的能力，交流和表达的能力等。新课标对初中物理演示实验提出了更高的要求，这也要求我们物理教育工作者要把握教育大方针，积极开展演示实验的设计与应用工作。当前，初中物理演示实验教学在实际开展中并不顺利，受到演示实验所需器材不足、实验现象不够立体直观、实验前期准备工作较多、实验的教学效果不理想等因素的影响，教师和学生对演示实验的重视度还不够高。因此，在初中物理教学中，我们十分有必要对演示实验做一些新的设计与应用，更大化发挥演示实验在物理课堂教学中的作用，本研究基于上述背景展开研究与讨论。本研究分六章。第一章绪论部分阐述了研究问题的提出、国内外研究现状以及笔者为完成本文所做采用的研究方法以及具体实践。第二章是关于笔者对目前初中演示实验教学现状所做的调查和分析部分。第三章围绕初中物理教学内容的几大板块分类例举了几个典型演示实验的设计以供研究讨论。第四章是在设计好演示实验的基础上对如何应用进行阐述并配以具体案例具体对象对比分析演示实验设计和应用的实际效果。最后得出第五章的文章结论。关于演示实验的设计环节是本章的重点篇章。关键词：演示实验；初中物理；教学设计Demonstrationexperimentisanimportantformofphysicsexperimentteachinginjuniormiddleschool,playinganimportantroleinPhysicsTeachinginjuniormiddleschool.Inthenewlyrevisedcurriculumstandard,itismentionedrepeatedlythatthestudents'PhysicalCoreliteracyshouldbecultivatedvigorously.Oneofthestudents'PhysicalCoreliteracyisexperimentalinquiry,andthedemonstrationexperimentcantrainthestudents'abilitytoobserve,analyzeanddemonstratetheabilitytocommunicateandexpress.Thenewcurriculumstandardsputforwardhigherrequirementsforthephysicsdemonstrationexperimentofjuniorhighschool,whichalsorequiresthatourphysicaleducatorsshouldgrasptheeducationgenerosityneedleandactivelycarryoutthedesignandapplicationofthedemonstrationexperiment.Atpresent,theteachingofphysicsdemonstrationexperimentinjuniormiddleschoolisnotsuccessfulinactualdevelopment.Itisnotaffectedbythelackofequipment,theexperimentalphenomenonisnotstereoscopic,thepreparatoryworkoftheexperimentismoreandtheeffectoftheexperimentisnotideal,andtheteachersandstudents'attentiontothedemonstrationisnothighenough.Therefore,inthephysicsteachingofjuniorhighschool,itisnecessaryforustodosomenewdesignandapplicationtothedemonstrationexperiment,andtogivefullplaytotheroleofthedemonstrationexperimentinthephysicsclassroomteaching.Thisresearchisbasedontheabovebackground.Thisstudyisdividedintosixchapters.Thefirstchapterintroducestheresearchquestions,theresearchstatusquoathomeandabroad,andtheresearchmethodsandconcretepracticetofinishtheresearch.Thesecondchapterisabouttheinvestigationandanalysisofthecurrentsituationofjuniormiddleschooldemonstrationalexperimentteaching.Thethirdchapterlistsseveraltypicaldemonstrationexperimentsaroundtheclassificationofphysicsteachingcontentsinjuniormiddleschoolforresearchanddiscussion.Thefourthchapterisbasedonthedesignofthedemonstrationexperimentonhowtoexplainhowtoapplyandtomatchtheconcretecasespecificobjectcomparisonandanalysisdemonstrationexperimentdesignandapplicationofactualeffect.Finally,thearticledrawstheconclusionofthefifthchapters.Thekeypartofthischapteristhedesignofdemonstrationexperiment.Keyword:Demonstrationexperiment;Juniorhighschoolphysics;Instructionaldes...
