How old are you? Section B教学评价教学评价 研究教材，挖掘教材，通过各种方式提高学生的学习兴 趣、调动学生的学习积极性是进行课堂教学所要解决的首要 任务，因此在本次教案的设计中我注重教学方法的灵活性， 力求呈现形式多样、自然，而且具有生活化。 一、教学目标一、教学目标 通过本节课堂教学，让学生能够掌握并应用新学习的文 具类单词；能够用英语熟练表达辨认物体，表示感谢和回谢 的方式；能够正确运用特殊疑问词 what 引导的特殊疑问句； 能够应用交际用语：How do you spell it? Can you spell it, please? 能听懂有关辨认物体、感谢和回谢等基本情况 的简单句对话或叙述；以及培养学生学习英语的兴趣，采用 游戏、小表演等形式激发学生的好奇心和求知欲等 二、教学设计二、教学设计 为了更好地实现教学目标，有效地突出重点、突破难点， 我在教学中采取了互动式的教学方法。利用实物和图片学习 新单词，让学生感知新句型“Whats this/that in English?”的用法，为后面学习做好准备 通过学习 eraser,给学生讲解 a 和 an 的用法，用顺口溜 “冠词 a/ an 两顶帽，许多名词都需要，单词开头元音素， 只能用 an，不用 a”，帮助学生记忆。 在前面基础上，通过互动方式，操练句型；通过让学生 朗读和仿编对话，训练学生灵活运用所学句型辨认物体、询 问他人是否会做某事以及表示感谢等，完成简单的交流。 三、教学过程三、教学过程 本节课中学生对于冠词 a/ an 的掌握有些难度，开始时 学生的有些不理解，在教学过程中运用一些帮助学生记忆的 顺口溜，如：冠词 a/ an 两顶帽，许多名词都需要，单词开 头元音素，只能用 an，不用 a，帮助学生提高记忆，收到很 好效果。 在练习对话过程中，学生害怕发音错误，不敢开口说英 语或者上台表演对话。在我的鼓励下，学生们都能勇敢地站 起来，从简单的对话操练开始，参与课堂活动，在切实提高 学生的口语水平同时，高标准实现本节课的教学目标。 四、教学效果四、教学效果 从实际的课堂效果来看，学生能够在教师创设的情景中 愉快地学习英语，增强教学的直观性和趣味性，也有效地激 发学生的学习兴趣，加深对所学单词与句型的理解，学生较 好地掌握了本堂课的知识。 Unit 1 Making New Friends Topic 3 How old are you?
