1、青岛版小学科学五年级上册声音的产生教学反思）青岛版小学科学教科书五年级上册青岛版小学科学教科书五年级上册声音的产生教学反思声音的产生一课在执教时，通过优美的乐曲带领学生步入奇妙的声音王国，这不仅激起了学生学习的兴趣和探究的欲望，而且引出了本课所要探究的问题。通过创设情境，引发学生想探究声音产生的兴趣，并通过学生的制造声音实验、使物体发声实验，让学生亲历探究过程。从学生制造声音到探究声音产生的实验，把选择制造声音的材料和方法的主动权交给学生。在实验中，人人有任务，人人都参与，教学中尽量给学生创造和提供机会，突出学生的参与性与主体性。在制造声音的基础上，让学生对声音的产生做出假设。假设不是凭空猜想

2、，而是从观察和收集资料出发，经过整理和分析产生的想像和概括。假设应该有一定的事实根据，建立假设后应用多种方法对其进行验证。探究活动的设计，体现了科学课标中的“科学探究既是科学教学的目标，又是科学学习的手段”。学生在亲自动手做的过程中学到了知识。并且探究过程的设计具有层次性，例如在探究声音产生的原因时，先设计了一个学生动手制造声音的活动，在此基础上再一次猜想声音产生的原因。交流时发现学生的注意力停留在对物体施加外力这一因素上，及时加以引导后，再放手让学生探究，学生的注意力由外力转移到发声物体的变化这一根本原因上来，也就是由现象到本质，交流时对于结论“物体振动产生声音”的得出就是水到渠成的事了。结

3、束语！祝大家学到有用的知识，提升自己的能力，实现自己的梦想，踏踏实实干好每一件事，为美好的明天而努力！16ev462jjqj7rdecq3ccpuewaxlknczuhsv,hjoazdp9ldidcn,f79tt66ats,z86vzovzq,jb31,.xsnsts1rufv4.nz34anidwi5,do6awk2qptknjdwfgfl1gia3umo.ywtmmfd,tv7urcc44d,2kn.7b.0kvznj1cxnxrbvhzr532v4y9icd1oj3ls4zs4oicek3,6,a9ga5x58x1ejht326bw56jyu3acxxdtnckj0x,imx1t4f3
