一、课题的提出
长期以来,教师讲、学生听,笔记记满一大本,成为高中英语课堂教学的主要形式。这种教学形式虽然在知识传授方面有容量大、花费时间少等优越性,但其单一的教学组织形式束缚着学生语言实践活动的全面开展,制约着学生语言运用能力的提高。在课堂上,教师容易偏重讲授英语语言知识而忽视对学生语言知识的训练,这样极易使学生成为语言知识的被动接受者,学到的是死知识,不能灵活运用,使不少学生失去学习英语的信心,制约了学生运用英语能力的提高及发展,不利于学生的自主学习,这些已很不适应新课程标准下的高中英语教学,课堂教学需要引进能面向全体学生的、有利于学生语言实践活动的教学模式──自主合作探究式学习。针对学生的实际情况,我们提出了三案一测五环节教学。三案即课前预习案,课中学习案和课后巩固案。一测即当堂检测,五环节即课前准备,展示交流,精讲点拨,检测反馈和小结作业。下面我以Unit 1 Module 4的词汇学习为例说说我们的做法。
二,课题实施
1. 课前预习学案 :目标明确,任务具体可操作,这一课前准备环节直接影响着课堂的效率。在传统的教学设计中,教师制订教学计划,把被管理者——学生置于一种被动地位,学生对计划全然无知,忽视了学生的主动性、积极性和创造性,使其失去培养自主学习、自我管理能力的机会。教师在备课时只注重熟悉教材内容,力图做到了因“材”施教。但忽视了学生这一主体因素,忽视了教学研究的对象,没有做到因“才”施教。所以学案的设计一定要有针对性,让学生知道做什么,该怎样做,要达到什么样的目标。
目标Learning aims:
1. To remember the new words and expressions in Unit 2.
2. To master the usage of some important words and phrases.

Step II. Important Phrases:
The following words & phrases are the important ones in this unit, and mastering their usage is your task. To find out the ones that you can’t understand, and then discuss in your group. If you still can’t make sense of them, write them on your paper.
1.幸亏,由于 摆脱,除去
2.对…感到满意 宁愿
3. 逐渐增强;建立 导致
2.课中学案:在这个过程中教师要充当设计者、管理者“促进者”、“咨询者”、“顾问”和“参与者”等多种角色,旨在促进整个教学过程的发展,帮助学生解决新旧知识之间的矛盾。同时在讲解过程中要进行选择性精讲。传统的词汇教学见什么讲什么,这样既浪费了时间,又导致学生没有了自己的思考。为了解决这个问题,我们采取让自主合作探究式学习,比如我给学生一定时间独立思考,然后在组内讨论并解答,最后在班内展示交流并提出自己的问题。这样学生们就会在解决问题的过程中找到自信和乐趣。课堂上进行选择性精讲时,特别注意对学生自学能力的培养,,让学生自己在实践中学会体会和总结。同时,在精讲的过成中,帮助学生构建知识网络,形成知识体系。“授之以鱼不如授之以渔”。这样做的目的正是引导学生利用自己所掌握的学习技巧完成自己终身学习的目标。经过多次教学实践,我们认为要采用这样的教学模式,应该要具备以下条件: 一.必须是一个开放式的课堂,必须是学生主体能充分发挥的课堂,教学的组织必须首先重视这一点; 二.应该是一个活动型占优势的课堂,都有学生感兴趣乐参与的活动,因此,教学设计中要非常重视活动的精心设计,要让学生动起来; 三.应该是一个以学习能力培养为主,基础知识学得为辅的课堂,即以知识的应用为主; 四.学生的基础知识利基础技能的学得主要是通过学生在教师指导下自身积极探究所得。。

三.存在的问题:
伴随着课堂教学进程的不断深入,也暴露了一些学习中的问题,如学生预习不到位,吃等食,学生难以在公众面前发言,小组成员有时不能和睦相处,小组讨论噪音较大,讨论时活动时间不能充分利用,小组合作学习组织不到位,出现小组中个别成员承担大部分甚至所有的讨论任务,而某些成员无所事事,出现“搭车”现象等等。因此.如何评价学生的学习,如何让学生长时间保持学习兴趣和积极性,并容易操作是我们今后进一步探讨的问题。总之,不管采取什么样的教学模式,让学生成为课堂的主体,并把自主学习变成一种学习习惯,培养其创新意识,发现问题解决问题的能力是我们所有教师的责任,这也是新课程改革的要求。
