1、苏教版小学科学五年级上册光的行进教学反思光的行进教学反思光的行进教学反思光的行进是苏教版科学教材五年级上册第二单元的第一节内容，通过本课的教学，让学生认识到了光在空气中的行进路线、光源、小孔成像、光的直线传播的应用等知识，下面谈一谈上完这节课的感受。一、激发兴趣，使学生一开始便兴趣盎然课前，我展示了从没有光到有光的变化，让学生意识到我们的生活因为光而更精彩。课堂上，又通过科学探究的方法，用实验探究了光在空气中的行进路线。如此经过提出问题、积极思考、交流发言、得出结论等环节后，让学生积极寻找解决问题的办法。二、准备充足，为学生开拓视野提供了准备教学过程中准备了两个实验。一个是光的行进的实验，主要

2、介绍光在空气中是怎样行进的，要求学生分组完成，用手电筒的光穿过三张带小孔的纸片，得出光在空气中是沿直线传播的结论；另一个是小孔成像的实验，利用小孔成像装置，观察蜡烛火焰和窗外景色，大大的提高了学生的兴趣。三、拓展和延伸本节课在讲小孔成像实验时，引导学生用自制教具进行观察，不仅体现了以生为本，更体现了自制教具在实际教学活动中的应用，取得了很好的效果。四、缺陷与不足班上只有一小部分人做了小孔成像装置，取得的效果有限，要是能让每个学生都课后去做一个小孔成像装置，那就更好了。结束语！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！1636uw,2e2gu
