17、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。.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

18、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
