1、青岛版小学科学三年级下册让更多的灯泡亮起来教学设计（让更多的灯泡亮起来教学设计让更多的灯泡亮起来教学设计 教学内容：青岛版小学科学三年级下册让更多的灯泡亮起来教学目的：1.观察电池盒，小灯座的结构特点；学会用电池盒，小灯座使小灯泡发亮；2.学会用简单的电路图记录自己的连接；.经历让更多小灯泡亮起来的活动过程，并且在活动中发现问题，提出问题，解决问题。培养学生合作的能力，在合作交流中体验学习的快乐。教学重点：通过动手实践，熟练连接电路，教学难点：并联电路的方法教学关键：合作能力的培养。突破难点措施：“捆绑式”评价，信息技术的运用信息技术运用：技术在评价环节起到的优化作用是用技术（照相机）记录学生
2、学习过演程，用演示文稿实现“时光倒流”，让学生观看自己在课堂中的表现，为学生自评和互评提供事实依据，使学生在事实的评价中，体验到参与、合作的幸福和快乐。同时，“过程的再现”也让学生再次重温教学内容，找出操作中的不足，巩固电路连接知识等。使用工具是小组合作评价量规。教学准备：教师准备：课件、分组实验材料（电池盒、导线、电池、开关等）学生准备：导线、小灯泡等。教学过程：一、 问题导入提出问题：我们已经能让一个灯泡亮起来了，怎样让更多的灯泡亮起来呢？二、大胆猜想 根据让一个灯泡亮起来的经验猜想。 三、实验验证：1.小组合作连接电路。要求学生用小灯泡2个，小灯座2个，电池盒，干电池一个，电线4根，小组
3、合作组装装电路，并画出电路图2.小组合作交流连接情况，并画出电路图。（小组合作交流的同时，教师及时抢拍照片）3.分析电路连接情况。4课件展示并联、串联图示。规范标准电路图。四、拓展 多个灯泡亮起来的生活运用。（节日彩灯等等） 五、课堂评价把照相机与多媒体连接，回放学生合作交流情况。（看到这些图片，你想说些什么呢？） 课前握手互相鼓励，争取多得几个“笑脸” 合作得多好啊结束语！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！16ygedneg46cs1hmy6b9ctyj8oyqowqdhhyw4kk7hju5soiz.vlz7skham.ipif
