11、那么，请大家跟着我一起走进韶关吧。”激发学生去了解、探索一个陌生城市的欲望，为下面课堂学习做铺垫。（二）任务驱动、自主探究（25 分钟）这是本课的教学重点，主要是让学生掌握在搜索引擎中查找及保存文字、图片、歌曲及整个网页的方法。因此，在这个环节，我采用分层教学的方法，设计了四个任务，让学生自主探究，掌握教学内容。任务一：查找和保存文字这一环节我首先设疑：“当同学们来到韶关后，首先要品尝一下韶关的美食，韶关有哪些特色美食呢？同学们能通过什么方式去了解呢？”引导学生说出通过搜索引擎查找关键字“韶关特色美食”。文档编码:CZ10Y10I6A2Y2 HD7U9F7S2G9 ZB4T3G9W3V8文档编

19、这一环节通过了解韶关特色美食的过程，让学生掌握保存文字的方法。任务二：查找和保存歌曲在这一环节，我把课前准备的一首客家山歌播放给孩子听，并简单介绍客家山歌，让他们感受流行音乐与客家山歌的不同。根据生活经验，学生已有自己保存歌曲的方法。因此，我先让他们介绍保存歌曲的方法，然后，让学生自己查找和保存一首客家山歌，和大家一起分享。通过查找和保存客家山歌，使学生知道保存歌曲的方法是通过“先搜索，再选择，然后点击鼠标右键，选择下载”这一过程（板书）实现的。任务三查找和保存图片首先，我先出示一组精美的韶关景点图片，让学生猜猜这些图片来自哪里？通过老师揭谜：来自韶关，让学生感受韶关美好的风景，激发他们进一步

20、了解的欲望。紧接着，提出任务：能否找到更多有关韶关旅游景点的图片并保存下来？最后，让学生带着任务，进行文档编码:CZ10Y10I6A2Y2 HD7U9F7S2G9 ZB4T3G9W3V8文档编码:CZ10Y10I6A2Y2 HD7U9F7S2G9 ZB4T3G9W3V8文档编码:CZ10Y10I6A2Y2 HD7U9F7S2G9 ZB4T3G9W3V8文档编码:CZ10Y10I6A2Y2 HD7U9F7S2G9 ZB4T3G9W3V8文档编码:CZ10Y10I6A2Y2 HD7U9F7S2G9 ZB4T3G9W3V8文档编码:CZ10Y10I6A2Y2 HD7U9F7S2G9 ZB4T3G9W

27、我对这些方法进行优化，使学生明确保存图片的简单方法是通过“先搜索，然后选择，最后点击右键选择图片另存为”实现的（板书）。任务四查找和保存网页这一环节，我首先设疑：“当同学们找到一个很喜欢的网页，想即使不上网也能随时在自己的电脑里打开，该怎么做呢？”引导学生说出收藏网页的方法时，再提出问题：除此以外，还有别的方法可以实现吗？然后，我介绍并演示保存网页的方法：选择“文件”菜单中的“另存为”（PPT）。最后，让学生比较保存网页与收藏网页的不同。通过比较，理解和区分两种方法的不同之处。（三）拓展练习、能力提升（10 分钟）学生掌握了保存文字、图片、歌曲和网页的方法后，为了加深学生对所学知识的理解、巩固

28、和运用，我设计了以下的三个练习：（PPT）：（1）搜索“东莞特色小吃”，并保存特色小吃的制作方法；（2）搜索“东莞旅游景点”，并保存美丽的景点图片；（3）搜索并保存一首你喜欢的歌，送给老师。通过学习，提高学生实践操作和动手解决问题的能力。（四）课堂总结、巩固知识（3 分钟）让学生说说通过本节课的学习，你掌握了什么内容？学生在表述中，梳理所学知识，形成自己的知识体系。四、板书设计（播放 PPT）文档编码:CZ10Y10I6A2Y2 HD7U9F7S2G9 ZB4T3G9W3V8文档编码:CZ10Y10I6A2Y2 HD7U9F7S2G9 ZB4T3G9W3V8文档编码:CZ10Y10I6A2Y2
