17、”及熟悉故 事的英文名称。3 .通过对话排序、图文配对和选词填空的听力方式训练，学生 能够掌握听力内容，提高了听力技能。4 .通过课件、图片和问答式的口语交际活动，学生能够表达对 故事的看法和原因；能够讨论故事的开展，能够讨论愚公的做法是否 恰当并说明理由。5 .通过利用多媒体进行课堂教学，对信息技术加以运用，设计 多种学生参与课堂的方式，学生能够积极思考，合作学习，探索创新。 通过本课教学，学生对信息技术的使用情况较好，学习效果和学习目 标的达成情况也比拟好。四、教师的支持以及信息技术的作用1、教师的支持教师在熟练掌握电子白板、PPT等信息技术工具的基础上，创设 发现和解决问题的技术环境，帮

18、助学生掌握用技术解决问题的策略， 指导和鼓励学生积极参与课堂，促进学生主动探究，帮助学生开展分 析总结能力和阅读理解能力。学生理解课文内容不需要像传统教学中 那样由老师滔滔不绝地讲解。这样，在信息化环境下学生从传统的被 动接受、机械训练中解脱出来，主动地去探索和发现，极大调动了学 生学习的主观能动性。2、信息技术的作用:(1)信息技术激发了学生学习兴趣，奠定了教学目标实现完成 的基础，有利于培养学生学习的自主性，加深了学生对知识的理解掌 握程度。拓宽了知识的形成渠道，化解了学生学习的难度，有助于培 养学生的创新能力，有利于提高课堂的教学质量。引入了人性化的评 价和激励机制，促进了师生互动、生生

19、互动，有利于建立良好的师生 关系。(2)信息技术有着支持学生学习的强大潜力，学生借助技术来 发现与解决问题，从而促进学生主动探究与应用知识，尝试将问题解 决过程可视化，开展了探究学习能力和自主构建的能力。多媒体教学 软件的运用，改善了人脑获得知识信息的感官功能，提高了视觉与听 觉传递信息的效率。在教学内容的展示上具有很强的真实感和表现 力，调动着学生的联想与想象，有利于全面开展学生的思维，学生通 过信息技术作手段从“听英语”转变为“学英语”。五、小结我使用鸿合电子白板、教学视频、Flash. PPT和微课等信息技 术工具在课堂教学中发现与解决问题，实现了课堂交流互动、课堂教 学的整合。在以后教学中英语课程的设计与实施应根据实际情况合理 地运用现代信息技术，要注意信息技术与课程内容的整合，注重实效, 要充分考虑信息技术对英语学习内容和方式的影响，开发并向学生提 供丰富的学习资源，把现代信息技术作为学生学习数学和解决问题的 有力工具，有效地改进教与学的方式，使学生乐意并投入到现实的、 探索性的教学活动中去。
