任务型教学模式的理论与实践.ppt

任务型教学模式的理论与实践,为什么提倡任务型教学模式？ Using is learning. Tell me, and I will forget. Show me, and I will remember. Involve me and I will learn. Dick All Wright：If the language activities involve the learners in solving communicative problems in the target language，language learning will take care of itself.,什么是任务型教学模式？ Richards, Platt and Weker(1986)给任务的定义是：An activity or action which is carried out as the result of processing or understanding language (i.e. as a response). For example, drawing a map while listening to tape, listening to an instruction and performing a command, may be referred to as tasks. Tasks may or may not involve the production of language. A task usually requires the teacher to specify what will be regarded as successful completion of the task. The use of a variety of different kinds of tasks in language teaching is said to make language teaching more communicative since it provides a purpose for a classroom activity which goes beyond the practice of language for its own sake.,什么是任务型教学模式？ 外语教学课堂中的任务是指学习者运用目标语进行交际以达成某一结果的活动。感性一点的定义是，任务是学习在其中发生的活动。 外语教学中界定的任务具有以下五个要素： 1.使用语言的目的。 2.产生目的的情景。 3.思考和行动的过程。 4.活动将导致结果（产品）的产生（这个结果包括具体可见的作品和问题的解决两大类别）。 5.学生需要借助于他们的知识、策略与技能结构来完成任务。,外语课堂应具有“变化性互动“的各项活动,即任务.学生在完成任务的过程中进行对话性互动,而产生语言习得(指通过交际无意识地接触语言系统而掌握语言).而不是单纯训练语言技能和学习语言知识的结果. 外语学习课堂中的活动具有以下五个方面的特征： 1.具有连贯性和统一性。 2.有意义、有目的。 3.具有明确的语言学习目标。 4.有始有终。 5.学生积极参与。,示例1 1.导入（教师介绍课文大意） 2.放录音 3.教师就课文内容提问，学生回答 4.教师归纳各段大意 5.讲解分析课文，学习语言点 6.熟读并准备复述课文 示例2 1.与课文内容有关的讨论，预测课文要谈的话题 2.学生快读课文，为课文选择一个合适的标题 3.学生较细致地阅读课文，填写图表 4.学生再次阅读并与同桌讨论，确定各段大意 5.师生讨论进一步疏通课文内容和语言点，学生作出笔记 6.学生听课文录音，准备相互提问,示例3. 1. Look at the topic and try to predict the content of the text and leadin pair work discussion. 在这一阶段，教师要使所设计的问题尽量贴近学生的实际。由于学生很可能已经预习了课文，predicting可能会变得乏味，所以教师可以让学生预测一下计算机的未来是什么样的，或者计算机在你的生活中的位置。（在这种活动中，我们可以看出：讨论是一种形式，而进行预测这一阅读的技巧训练才是活动的实质。） 2. Discuss in pairs or groups functions that a computer has and make a list of it. Compare your list with your friends and the function mentioned in the text. Try to find three differences between your list and the text. （这种活动，实际上也是一种阅读技巧的训练。学生练习的是通过略读和搜索阅读来查找有关信息以及学生的归纳能力。）,3. Contextualized reading comprehension.主要练习学生凭借语境/对上下文的理解而猜词判义的能力。（同时也是为了消除学生在考试中对生词的焦虑感和恐惧感。） 4. Read and fill in a chart/table. 再次阅读文章，并填写后面表格空白处。（这里训练的是对阅读所获信息进行归纳分类的能力。） 5. A problemsolving activity.根据三个顾客的不同要求分别为他们选择一台电脑并解释理由。（这一步是总结性的归纳，也是活动的高潮，它是前四个活动中所练习的能力的综合体现。）,任务型教学模式的理论依据 克拉申（S . D . Krashen )模式。它主要描述习得过程。这一模式的基本思想可以概括为:外语能力是在较低的情感过滤条件下,通过足量的可理解输入,以可预测的顺序习得的。这一模式是:,任务型教学模式的理论依据 Long (1983) : conversational interaction Language Acquisition Modified Interaction 1） 变化性互动可使输入成为可理解性； 2） 可理解性输入有利于语言习得； 3） 变化性互动有利于语言习得。,第一位将TBL体现在教学大纲和教学实践中的是Prabhu。1979年，Prabhu在印度南部的Bangalore开始把当时看来很激进的理论假设付诸于实践的大胆教学试验。他认为：Students may learn more effectively when their minds are focused on the task, rather than on the language they are using. Prabhu被认定为任务型学习活动的创始人。 Jane Willis。Jane Willis 认为,任务型学习活动强调的是语言学习中“意义至上、使用至上”的原则，这就要求learners 为完成一个任务而在活动中以交流为目的（with some kind of communication purpose）真实地使用语言（process the text for meaning in order to achieve the goals of the task）。而这种活动需要学生参与到reading, listening or reviewing之中。,任务的结构性: Nunan(1989) Goals Input Activity Teacher/student Role (facilitator,organizer,monitor,partner) setting (individual,pair, group, class ) 任务型教学的步骤： Jane Willis 把任务型学习模式分为三个阶段或三个环节： 前任务(Pre-Task) Introduction to the topic and task. 任务环(Task-cycle) Task， planning and report. 语言知识要点(Language focus) Analysis and practice.,Willis (1996) 认为，一般来说“任务”可分为六种类型： 六种任务类型均反映了学生的认知过程，都遵循了从易到难，从简单到复杂的原则，位于上方的三种任务类型的难度低于下面的三种，,语言教学中的“任务”六种类型典例： 类型一：列举型任务(listing) 1Annies mother usually goes shopping early on Sunday morning.

Work in threes .Read the problem and think of an answer to help the farmer. 3. In groups ,read the story again.

Work in a small group and talk about the ways you learn things: by reading, listening, doing or.,类型六：项目型任务 (project) 这些任务要求学生围绕某一主题，通过查找资料、与别人交谈等方法获得知识，其学习成果可通过回答教师问题、编辑手抄报等形式表现出来。这些任务为学生提供了一个很好的学以致用的机会，一个很广阔的自由发挥的空间，它是素质教育落实到英语课堂教学之中去的一个极有效的途径。 例如：Littlejohn提出了一种新的任务型学习活动的模式：Question Posters How long do crocodiles sleep? Where do birds go in the winter? How do birds know where to go? Animal World What do whales eat? How can insects fly?,任务型教学模式的注意事项： 第一, 牢记教学目标，切忌追求花哨形式。 第二，任务的设计一定要与输入的内容和语言相关联。 第三，在进行任务型学习活动时，不少教师对同桌活动或小组活动的有效使用缺乏过细的考虑。实际上，在进行同桌/小组活动前，应先花上2至3分钟的时间，让学生自己考虑一下，并列出要讲的提纲。这样，接下来的讨论就不至于冷场。此外，讨论、对比彼此所列的提纲也会使活动变得更个性化，能激发学生的兴趣。 第四，我们的教师对小组活动中小组内部成员在活动中的作用还缺乏深层次的认识，而只是把小组活动简单地看作是几个人围在一起讨论就行了。实际上有些小组活动开展得好，有些不好，这恐怕和小组成员在活动中担任的不同角色有关。国外学者把小组活动中各个成员的自然角色分成：组织者（Organizer），鼓励者（Encourager），协调者（Harmonizer），贡献者（Contributor），煽情者（Agitator），搞笑者（Joker），随大流者（Follower）和旁观者（Observer）。每个人对自己心理角色的认同是与其个性以及他在集体中的位置和责任有关的。但是，如果小组成员能在某种程度上都能了解自己的心理角色，并在一定程度上有意识地去完善它，小组活动的教育意义就会远远大于活动本身。,任务型教学模式的实例； Teaching procedure: I. Pre-task Teacher introduces the topic and tries to motivate the students by talking about their problems. Brainstorm on words, phrases expressing problems and their solutions. II. Task cycle Task 1:1) Skimming & matching Ask the Ss to skim the Ss five letters and Auntie Wangs answers in 3 minutes to get the main ideas. Then matching those letters asking for advice about their problems to Aunite Wans answers. Discuss in pair.,2)Planning and report 1 Ask the Ss to plan brief oral report for whole class, to compare their answers. Task 2: 1) Scanning, listing & problem-solving Ask the Ss to scan the materials in 2 minutes to make sure of the Ss problems and Auntie Wangs answers. Work in small group. Finish the chart by listing the specific information in 1 or 2 sentences. Then discuss the problems again and write down your own answers to those problems in 1 or 2 sentences.,Some Ss are asked to plan oral report for whole class first, and then to exchange lists
