走进信息时代(说课稿)
新民小学 寻英
每当我们提到长城，自然会联想到烽火台。烽火台筑在长城沿线的险关和交通要道上。古代士兵一旦发现敌情，便立刻点燃烟火发出警报。相传西周有个腐败的周幽王，他的爱妃褒姒长得非常美丽，只是从来没有笑容。一天黄昏，周幽王带着褒姒登上烽火台，命令士兵点燃烟火。邻近的诸侯们看到烽火，以为敌人来犯，慌忙领兵赶到城下救援。但见到灯火辉煌，鼓乐喧天，一打听才知是周幽王干的荒唐事儿，只好气愤地收兵回营。褒姒见到官兵们狼狈的模样，果然开颜一笑。这就是“烽火戏诸侯〞的故事，它说明早在三千多年前，我国就有了利用烽火传递信息的方法。
我们今天的探究，就要从烽火台开始，直到发现电脑网络通信的奥秘，寻找人类社会走向信息时代的脚印……
一、            本课的教学目标
本课有许多现代科技知识性的内容，相对品德课而言，它浓浓的品德味道比拟的淡，而现代生活感和时代的科技感比拟的强烈，给学生的是各种感官的刺激。趋向于品德课另一特点——综合性。如何把握综合性，提高品德课的实效性，在对孩子的知识根底和学习经验进行分析后，我认为这节课在知识上主要是让孩子们了解通信的开展，知道现代通信的种类和方式。在情感目标上，让孩子们能感受到现代通信与人们生活的密切关系；现代生活离不开通信；离不开高科技的支持；并且利用它增进与他人的交往和情感。在行为目标上，让孩子们学会选择不同通信方式，与自己的亲友进行通信联系。为他们今后翻开世界的窗口埋下伏笔。

通过课前调查，我了解到班里大多数孩子知道通信，并且曾经使用过，那么在课堂上学习要增加一些必要的量，让孩子们对通信有个完整的认识，成了我这堂课首先要考虑的问题。于是我的教学重点是让孩子们真实的感受到我们的生活离不开通信，通信无处不在的为我们生活效劳，并且会使用我们现代化的通信工具。在第一环节里给学生布置了三项任务1、像烽火台这样传递信息的方法，你还发现了哪些？请说出3种以上。 2、你感到，我们和我们的祖先，传递信息的方式发生了哪些变化？3、你认为哪些东西出现，说明人类社会已经进入了信息时代？第二环节是点击现代，真实感受，我将全班同学将分成6个小组共同承当上述任务；小组分别命名为信息传播史探究组、邮政通信探究组、电报电话通信探究组、播送电视通信探究组、卫星通信探究组和电脑网络通信探究组学生想好自己参加哪一个组，明白小组内的分工，明白自己承当的任务，思考1、我应该做些什么？2、我打算如何做？第三环节是老师让每组学生拥有一台电脑并提供一些信息资源让他们通过电脑查找自己所需要的资料，这个环节就是一个现场反响的环节。。第四个环节课外延伸，让孩子们能实践运用，尝试和老师联系，孩子们简直有点兴奋，对他们来说，可能是史无前例的，老师给他们名片，而且给的这样真诚，真心真意和他们做朋友，他们真的很开心，班级反响非常好，班级里拥有QQ的小朋友，都已经加我为好友了，我这样的设计不露痕迹，效果却是加倍的，真正到达一种无痕的教育，学生使用通信工具也完全是一种内在需要。这四个环节，环环紧扣，层层递进，呈现的是一个有梯度上扬的过程，本节课自始自终围绕信息这个主题，展开活动。真正表达了现代生活必需要用通信。
三、            在教学策路上的选择
本节课我花得心思真的挺多的，把课上得他们喜爱是挺重要，要时时刻刻的吸引孩子们，这样他们才会和你合作，参与课堂。了解古代现代的通信工具他们很好奇，自己去调查了。我把我的照片展示给他们看，他们喜爱，也知道了时尚的网络通信。等到教师名片的出示就是整堂课高潮后的沸点，孩子们都拿起笔来记下的通信方式。他们会迫不及待的去使用通信和我联系，这也是教师课堂教学和人格魅力的最正确表达通信连着师生间的浓浓的情意，让师生共同走进信息时代。。
