表二：单元大观念：
学情分析
（一）自然情况 本单元围绕“未知的世界”这一话题，开展教学活动，学习《外星人到来》、《不明飞行物》、《科幻小说》等未知世界的故事。符合Module 4 Discovery这个话题的内容探究，以及八年级学生对知识的汲取需求。 （二）已有基础 (1)学生对“未知的世界”的话题比较熟悉，对外星人的故事着浓厚的兴趣，并愿意分享。 (2)学生已经基本掌握了课内词汇并能理解because,as,since引导的原因状语从句和用because of陈述理由。约有70%的学生可以准确表达含有because,as,since和because of的句子。 （三）存在问题
《外星人到来》属于The unknown world这个话题，涉及的知识面非常广，学生虽然在小学和七年级上册涉猎了一些，但是比较浅显，涉及的知识面也不够广泛。本单元的教学内容应该站在一个更高更宽广的角度去理解。 （四）解决措施 1.鼓励学生在课堂上积极踊跃发言，尊重每个学生的想法，并给予客观公正的评价，而不是期待唯一的标准答案。 2. 培养学生思考如何描述外星人和地球人相遇时的有趣故事。 3. 在教学过程中，以学生为中心。创设让学生合作交流的学习情境，一起探讨、讨论，共同完成学习任务。并鼓励学生将所学内容与家长进行分享。 4. 教学方式灵活多样，根据学生随堂掌握情况，及时做出调整和改进。 5. 从多角度多维度对学生进行多方位评价。
