1Implementing Task-Based Language Instruction 实施任务型语言教学 Luo ShaoqianThe Chinese University of Hong KongBeijing Normal University
2Three Dimensions of Language Teaching Goal (i.e. ‘why’ the language is being taught)Content (i.e. ‘what’ is taught)- Type A syllabuses- Type B syllabusesMethodology (i.e. ‘how’ it is taught)- accuracy- fluency
3Grammar Translation Goal Content Methodology Ability to read literature in the L2Type A (list of grammar rules and words to be taught)Accuracy (i.e. accurate translation of L2 into L1)
4Audio-Lingualism Goal Content Methodology Ability to communicate Type A (list of linguistic items to be taught)Accuracy (I.e. focus on target-like use of the L2)
5Notional/Functional Teaching GoalContentMethodologyAbility to communicateType A (i.e. a list of notions and functionsAccuracy (i.e. focus on target-like use of the L2)
6Task-Based Teaching Goal Content Methodology Ability to communicate Type B (i.e. a series of message-focused tasks)Fluency (i.e. focus on message conveyance)
7Traditional - Task-based Task-based pedagogy-- students able to control topic development-- speakers can self-selectTraditional form-focus pedagogy--Teacher controls topic development-- turn taking is regulated by the teacher
8questions that questioner already knows the answer to little need or opportunity to negotiate meaningScaffolding directed primarily at enabling students to produce correct sentencesquestions that the questioner does not know the answer toOpportunities to negotiate meaning when communication problems ariseScaffolding directed primarily at enabling students to say what they want to say
9Form-focused feedback,i. e Form-focused feedback,i.e.the teacher responds to the correctness of students’ utterancesThe teacher repeats what a student has said for the benefit of the whole classContent-focused feedback,i.e.the teacher responds to the message content of the students’ utteranceA student elects to repeat something another student or teacher has said as private speech or to establish intersubjectivity
10First generation tasks The main aim of first generation tasks is to develop students’ communicative ability in a specific type of situation or area of language. The task is often structured around a particular set of functions or a simple problem.(Littlewood, 2004; Ribe & Vidal, 1993)
11Second generation tasks The tasks in the second category pose challenges of a broader nature. They aim at developing not only communicative skills but also general cognitive strategies of handling and organizing information, such as analysing what information is needed in order to complete the task, collecting information,selecting relevant data…
12Third generation tasks With third generation tasks, the scope widens further. In addition to the communicative and cognitive strategies, they also aim to develop the personality of students through the experience of learning a foreign language. They go further than the previous tasks in aiming to fulfill wider educational objectives, such as enhancing motivation and awareness, developing creativity and interpersonal skills…
13Task TypesUnfocussed tasksa. Pedagogicb. Real worldFocused tasks
14An Example of a Pedagogic Task Four students – each has one picture and describes it to the rest of the class.Students from the rest of the class ask the four students questions about their pictures.One student from the class tries to tell the story.If necessary Steps 2 and 3 are repeated.
15Some Typical Pedagogic Tasks Information-gap tasks (e.g. Same or Different)Opinion-gap tasks (e.g. Balloon debates)Reasoning-gap tasksPersonal tasksRole-play tasksNote: Tasks can be dialogic or monologic; they can be performed orally or in writing.
16A Real-World TaskLook at the message below. Listen to Mr. Pointer’s instructions on the tape. Make notes if you want to. Then write a suitable reply to Lesieur.Dear Mr. PointerPlease send flight number, date and time of arrivaland I will arrange for someone to meet you at theairport.Lesieur.
17Role-play activitiesVery often in role-play situations there is no actual outcome for students to achieve, other than to enact their roles. Students have to think of suitable things to say to each other, but they are unlikely to be exchanging real meaning.Jane Willis
18Two Approaches to Using Tasks Use tasks to support a Type A approach.- task-supported teaching (Type A)- weak form of communicative language teachingUse tasks as the basis for teaching- task-based teaching (Type B)- strong form of communicative teaching
21A Framework for Describing Tasks GoalInputConditionsPredicted outcomes:a. Processb. Product
22Implementing task-based instruction from a processing-pedagogic view point Dangers: if implemented without care, likely to create pressure for immediate communication rather than inter-language change and growth; may encourage learners to use excessively and prematurely lexical modes of communication.Possibility to minimize the dangers: to draw on cognitive psychology and second language acquisition research that emphasizes processing factors.Learners must be able to develop their inter-language systems in more complex ways through cycles of analysis and synthesis: revisiting areas; learning in a simple, straightforward manner; developing by relexicalizing available syntactically which need not be used on such a basis.
23The Methodology of Task-Based Teaching Three phases in a task-based lesson:Pre-task phaseMain task phasePost-task phase
24Task 1 Highlighting main ideas Task 2 Planning the weekendTask 3 Expressing environmental viewsTask 4 Shopping in a supermarketTask 5 Radio weather information
27Pre-task workAt this stage, the task itself is the primary factor, taskcompletion is the aim that dominate.1)To set up the relevant language for a task: to deal some form of pre-teaching, can be both explicit and implicit2) Give learners a pre-task to do and then equip them with the language they need
28Pre-task workto ease the processing load when learners doing a task: a range of tasks can be used to reduce 认知复杂度 –1) familiarity leads to recall schematic knowledge they have;2) observe similar tasks on video or listen to or read comparable tasks;3) do related tasks to activate schema4) engage in pre-task planning: language to use, meanings to express.So they can devote more attention to how to carry out thetask and produce more accurate, complex, and fluentlanguage.
29The Pre-task Phase Three purposes: ---to serve to introduce new language that learners can use while performing the task;---to mobilize existing linguistic resources;---to ease processing load, and to push learners tointerpret tasks in more demanding waysSome options:Allow the students time to plan.Provide a modelDo a similar taskPre-teach key linguistic items
30The Pre-task Phase On general cognitive demands of the task 对任务要求的总体感知 An emphasis on linguistic factors 关注语言因素Supporting learners in performing a task similar to the task they will perform in the during-task phase of the lesson 让学生做一些在后面完成任务时需要的准备工作Non-task preparation activities--- brain storming 大脑风暴--- mind map 思维图
31The Pre-task Phase Addressing linguistic demands of a task ---predicting, i.e. asking learners to brainstorm a list ofwords related to the task title or topicProviding a model 提供一个示范Asking students to observe a model of how to perform the task 让学生观察完成任务的模式Performing a similar task 完成一些简单的任务--- simply observing others perform a task can helpreduce the cognitive load on the learner(Skehan, 1996)
33The During-Task Phase Some options: Participatory structure 参与方式: Whole-class vs. small group work; individual or interactionSet a time for completing the task.Vary the number of participants.Introduce a surprise element.Tell students they will have to present a report to the whole class.pair and group work are seen as central to task-based teaching; not all tasks are interactive
34（二）新语言材料的操练（during- task phase） the main task phase是指语言技能的习得过程。研究内容：探讨了如何使语言技能的训练能够吸引学生积极、主动的参与，如何使语言知识的积累、语意功能的训练与主题结合。
35During the taskAt this stage, learners are reminded that fluency is not theonly goal during task completion, and that restructuringand accuracy also have importanceTask choice: the appropriate difficulty level.too difficult: excessive mental processing – to communicate any sort of meaning: ellipsis, context, strategies and lexicalization which reduce the pedagogic value of a task-based approach.2 too easy: boring, no serious engagement – no gain in terms of stretching interlanguage or automaticity development (Swain, 1985)
36During the task Syllabus: implementation decisions – to alter the task difficultymanipulate the way in which attention is directed- accuracy to be stressed?- specific structures to be usedto make a task less difficult: visual support, such as a diagramto make a task more difficult: surprise elements which learners don’t expect, e.g. additional evidence in a “judge” task.The communicative stress factors: time, modality, participants/relationships, importance of the task, participants’ control over the task.
37The Post-Task Phase Three major pedagogical goals: --- 提供再做任务的机会 （to provide an opportunity for a repeatperformance of the task）--- 反思任务是怎样完成的（to encourage reflection on how the task wasperformed）--- 关注语言的形式（to encourage attention to form）
38Post-task activities Post 1 performance: the knowledge while the task is being done may have to be re-done publicly – this leads to learners’ attention to the goals of restructuring and accuracy.analysis: the concern with syntax and analysis is infiltrated into the task work without the heavy-handedness of the teacher intervention and error correction.
39Repeat performance Carry out second performance publicly （全班，当众） －Complexity increases 复杂度提高了－Express more clearly 表达更清楚了－Become more fluent 语言更流利了
40Post-task activities Post 2 examine task sequences, task progression, and how sets of tasks relate to one another: 1) to repeat tasks so learners are more effective with the analysis and synthesis2) parallel tasks: tasks are similar but with new elements so to engage the learner interest.2 task families: groups of tasks resemble one another and have similar language or cognitive demands (Candlin, 1987) so learners are clearer of the goals of such task groups and teachers and learners share views about task requirements.
42Reviewing of learner errors Teacher moves from group to group to listen and note down the errorsAddress these errors with the whole class- can be written on the board- students can be invited to correct it- listen again and edit their own performance- teacher comments on
43Consciousness-raising tasks There is an attempt to isolate a specific linguistic feature for focused attention 就某一语法现象单独讲解The learners are provided with data that illustrate the targeted feature or an explicit rule describing or explaining the feature给例子说明语法用法或对语法详细描述The learners are expected to utilize intellectual effort to understand the targeted features 通过思考理解语法用法Learners may be optionally required to verbalize a rule describing the grammatical structure 可以是学生口头表达To direct students to attend explicitly to a specific form they used incorrectly or failed to use at all in the main task 补充不足
45Noticing activities Focusing on linguistic form Dictation Editing Writing and teacher comments
46Reflecting on the taskPresent a report on how they did the task and what they decided or discovered – oral or writtenSummary the outcome of the taskReflect or evaluate of their own performance (fluency, complicity or accuracy)Metacognitive strategies 元认知策略(planning,monitoring and evaluating)

49The Foods I Eat (for students) Task 1: Having a picnicSituation: Some children are going to have a picnic. What food are they going to have? Can you give them some ideas? What food do you usually have? Name some of your favourite ones.Subtask1: What food do they want for the picnic?Instruction: Now the children are deciding what they want. Look at the picture carefully and find out the answer by filling in the blanks.Subtask2: buying food at the food shopInstructions: Lily and Mary are at the supermarket. They are buying food for the picnic. Please listen to their conversation carefully. Fill in the chart.Subtask3: eating at the picnicInstructions: Now the children are at the picnic. They have lots of food. Read the conversation between Coco and Sam. Complete the one between Helen and Tim.
50The Foods I Eat (for teachers) Task 1. Having a picnicAims of the task:1. to identify kinds of foods2. to express likes or dislikes3. to understand the communicative language at the food shop
51Subtask2: buying food at the food shop Task requirements: Communicative language at a shop. Listening skillGeneral: To ask and answer questions about buying and selling at shopsSpecific:To assess students ability to:-make a conversation at a shop.-get information from a conversation.-sum up the main idea of the conversation.-write money in numbers.
52WHO'S WHO IN THE FAMILYFamily members, BE, Who / whoseStructure/Vocabulary:Functions:Talking about families
53Materials:(1) Cards with description of a new family (1per student)(2) "Find Someone Who..." Sheet(3) Model Paragraph
54PRE – ACTIVITY Skills: Speaking and listening Organization: Whole classProcedures: Class asks teacher about his / her family(real) or imaginary.
55ACTIVITY Skills: Speaking, listening, writing. Organization: Mixer Procedures:(l) Give out cards (one per student): explain that this is their new family.(2) Explain any vocabulary or pronunciation problems.(3) Give out "Find Who...?” sheet and explain how it works. Students will answer with information from their new families.(4) Done as a mixer. The first student to fill out the sheet correctly wins.
56POST – ACTIVITY Skills: Writing, (speaking, listening) Organization: Individual / pairs.Procedures:(1) Go over model paragraph.(2) Individually, students write similar paragraphs about their new families.(3) Then, put students into pairs and they correct each other's paragraphs. (The paragraphs can later be collected and corrected by the teacher.)
58FIND SOMEONE WHOSE... mother is deceased....mother is an actress.…father is a taxi driver.FIND SOMEONE WHO -is a student.is retired.is 20.
59Model Paragraph My Family My name Is Olivia. I'm 10 and I'm a student. My father's name is Joseph. He’s a scientist. He’s 44. My mother 's name is Joan. She is a teacher. She’s 42. I have no brothers or sisters.MY FAMILY
60Focusing on forms 学习语法 direct focus on grammar -- focus on the features of the forms讲解重点语法-- address errors 纠正语言错误-- address gaps in the students’ knowledge 补充语言知识不足
61Focussing on FormOpportunities to focus on form arise in task-based teaching:Definition:Focus on form … overtly draws students’ attention to linguistic elements as they arise incidentally in lessons whose overrriding focus is on meaning or communication. (Long 1991)cf. Focus on forms
62Three Types of Focus on Form Reactive focus on form (error correction)Teacher-initiated focus on formStudent-initiated focus on form
63Reactive Focus on Form: An Example T: What were you doing?S: I was in pub(2)S: I was in pubT: In the pub?S: Yeh and I was drinking beer with myfriend.
64Dual Focus Learner 1: And what did you do last weekend? Learner 2: … I tried to find a pub where you don’t see – where you don’t see many tourists. And I find oneTeacher: Found.Learner 2: I found one where I spoke with two English women and we spoke about life inCanterbury or things and after I came backTeacher: Afterwards …
65Combinations of skills listening with speaking and writingreading with speaking and writingsometimes all four skills
66Problems and Solutions 1. Students lack proficiency to communicate in the L2Devise activities that develop ability to communicate gradually.2. Students unwilling to speak English in class.Use small group work; allow planning time; learner training3. Students develop pidginized language systemSelect tasks that demand fully grammaticalized language
67Problems with the Educational System and Solutions 1. Emphasis on ‘knowledge’ learningReview philosophy of education.2. Examination systemDevelop new more communicative exams3. Large classesUse small group work; develop tasks suited to large classes.
68ConclusionsTask-based teaching offers the opportunity for ‘natural’ learning inside the classroom.It emphasizes meaning over form but can also cater for learning form.It is intrinsically motivating.It is compatible with a learner-centred educational philosophy.It can be used alongside a more traditional approach.
