unit 3　under the sea 教案

指导思想与理论依据　　　
指导思想
本课题努力将新课程的理念融入教学之中，将语言知识与学生的现实生活紧密联系；将课堂教学放在具体的语言情景之中；把听、说、读、写语言技能的训练综合运用于课堂教学之中。通过探究法、观察法和发现法，让学生发挥主观能动性，改变原有的教师说解、说教的形式，重视知识和结论形成过程。努力发挥形成评价的激励机制，利用两两合作、小组活动的方式，激发学生参与教学的热情。根据学生的认知能力和接受程度，设计了编写对话和仿写作文等任务，使任务具有可操作性，让学生整堂课都处于新鲜感不断的亢奋状态中，并产生继续学习的动力。
总之，本次设计的宗旨是努力提高课堂教学的实效性，使学生能够提高语言的实际运用能力，达到最终教学的目的。
理论依据
《普通高中英语课程标准》明确提出：“要通过设计丰富多彩的课内外学习活动，使学生在参与交际活动的过程中形成交际策略。”和“教师要引导学生主动学习，帮助他们形成以能力发展为目的的学习方式，鼓励学生通过体验、实践、讨论、合作和探究等方式，发展听、说、读、写的综合语言技能。”
教材内容分析　　　　　
unit 3的主题是“under the sea”，中心话题是海底世界，听、说、读、写活动主要围绕海底动植物、海底奇妙景观，以及有关大海的神话故事展开的。教学内容由两篇阅读，两份听力，三个话题讨论和三个话题延续性写作任务组成。
阅读内容是：1.两起虎鲸轶事。(p20－21)
2．一篇有关海洋见闻和感受的日记。(p24)

2．用speaking and writing中的抱怨用语在设置的情境中礼貌抱怨。(p27)

学情分析　　　　　
高二学生对这个新鲜话题普遍很感兴趣，积极性也比较高，但大部分学生对新学的单词词汇还是比较生疏，运用英语进行交际的能力还是比较薄弱的，因此教师可以利用丰富多彩的图片资源，在任务型教学下完成本课题的学习。班级里的学生水平参差不齐，有些差距还是比较大的，因此在教学过程中，布置的任务要兼顾各个层次的学生，使他们通过听、说、读、写都有所获。
