What is a task?

1. A task involves a primary focus on meaning?.

2. A task has some kind of ‘gap’.3. The participants choose the linguistic

resources needed to complete the task.4. A task has a clearly defined outcome.

Page 5: Task based-language-teaching

An example

I am going to play a number game with you. When I have finished:

1. Play the game in pairs.2. Imagine you are writing a book of games for

children and want to include this game. Write an entry in the book for this game.

3. Compare your entry with that of another student. Whose entry is better?

4. Develop a set of criteria for evaluating written entries in the book.

Page 6: Task based-language-teaching

Some questions

1. What type of task is this?- information gap/ opinion gap- one way./ two way- open/closed2. What language skills were involved in performing

this task?3. What kinds of ‘processing demands’ does this task

place on students?4. Are there any linguistic forms that are ‘essential’ or

‘useful’ for performing this task?5. How could you decide if this task has worked?

Page 7: Task based-language-teaching

Why do TBLT

1. Tasks can be easily related to students’ real-life language needs (i.e. ‘pedagogic tasks’ can be designed to reflect ‘target tasks’).

2. Tasks create contexts that facilitate second language acquisition (i.e. an L2 is best learned through communicating).

3. Tasks create opportunities for focusing on form.4. Students are more likely to develop intrinsic

motivation in a task-based approach.5. A task-based approach enables teachers to see if

students are developing the ability to communicate in an L2.

Page 8: Task based-language-teaching

Using tasks in language teaching1. Task-supported language teaching i.e. the syllabus is a structural one and the

approach is ‘focus on forms’. Tasks (really ‘situational exercises’) are used in the final stage of a PPP methodology

2. Task-based language teachingi.e. the syllabus is task-based and the

approach is ‘focus on form’. The methodology centres around students performing a series of tasks.

Page 9: Task based-language-teaching

The methodology of task-based teaching

Page 10: Task based-language-teaching

Two aspects of methodology1. The organisation of task-based lessons

- pre-task phase- main task phase- post-task phase

2. The participatory structure of task-based lessons- individual student activity- teacher-class activity- small group work

Page 11: Task based-language-teaching

Options for the Pre-Task Phase

The purpose of the pre-task phase is to prepare students to perform the task in ways that will promote acquisition. Three approaches:- motivational- focus on cognitive demands- focus on linguistic demands

Page 12: Task based-language-teaching

Procedural Options for the Pre-Task Phase1. Supporting learners in performing a task

similar to the main task2. Providing learners with a model of how the

task might be performed.3. Engaging learners in non-task activities

designed to help them perform the task.4. Providing learners with the opportunity to

plan how to perform the task.

Page 13: Task based-language-teaching

Performing a Similar Task

See Prabhu (1987)- the pre-task is a task in its own right- it is performed through teacher-class

interaction with the teacher using questions to guide the students to the task outcome

Rationale can be found in sociocultural theory – expert-novice interaction scaffolds zones of proximal development.

Page 14: Task based-language-teaching

Providing a Model

Providing a demonstration of an ideal performance

Analysing the features of an ideal text Training in the use of a strategy (e.g. learning

to live with uncertainty) Effects of such task ‘priming’ need

investigating (cf. Lam and Wong 2000)

Page 15: Task based-language-teaching

Non-Task Preparation Activities These centre of reducing the cognitive or

linguistic load: Activating schema relating to topic of the task

(e.g. brainstorming) Pre-teaching vocabulary (e.g. Newton 2001 -

predicting, co-operative dictionary search, matching words and definitions)

Page 16: Task based-language-teaching

Strategic Planning

Students have access to task.Options: Unguided planning Guided planning (focus on content vs. focus

on linguistic form) Time allocated (Mehnert 1998) Participatory organisation

Page 17: Task based-language-teaching

Example of Guided Planning – Foster and Skehan 1999

 

Strategic planning options Description

1. No planning The students were introduced to the idea of a balloon debate, assigned roles and then asked to debate who should be sacrificed.

2. Guided planning – language focus The students introduced to the idea of a balloon debate and shown how to use modal verbs and conditionals in the reasons a doctor might give for not being thrown out of the balloon (e.g. ‘I take care of many sick people – If you throw me out, many people might die.’

3. Guided planning – content focus The students were introduced the idea of a balloon debate. The teacher presents ideas that each character might use to defend his or her right to stay in the balloon and students were encouraged to add ideas of their own.

Page 18: Task based-language-teaching

Options for the Main Task PhaseTwo sets of options: Task-performance options (relating to

decisions taken prior to performance of the task)

Process options (relating to on-line decisions taken during the performance of the task – focus on form)

Page 20: Task based-language-teaching

Task Performance Options

Main options are: Performance of task with or without task

pressure (Yuan and Ellis 2003) Performance of task with or without access to

input data (‘borrowing’ – Prabhu) Introduction of surprise element (cf. Foster

and Skehan 1997)

Page 21: Task based-language-teaching

Theoretical rationale for focus on form To acquire the ability to use new linguistic forms communicatively,

learners need the opportunity to engage in meaning-focused language use.

However, such opportunity will only guarantee full acquisition of the new linguistic forms if learners also have the opportunity to attend to form while engaged in meaning-focused language use.

Given that learners have a limited capacity to process the second language (L2) and have difficulty in simultaneously attending to meaning and form they will prioritize meaning over form when performing a communicative activity (VanPatten 1990).

For this reason, it is necessary to find ways of drawing learners’ attention to form during a communicative activity. As Doughty (2001) notes ‘the factor that distinguishes focus-on-form from other pedagogical approaches is the requirement that focus-on-form involves learners briefly and perhaps simultaneously attending to form, meaning and use during one cognitive event’ (p. 211).

Page 22: Task based-language-teaching

Incorporating a Focus on Form Attention to form in the context of performing

a task can occur: Reactively (through negotiation of meaning or

form) Pre-emptivelycf. Ellis, Basturkmen and Loewen

Page 23: Task based-language-teaching

Implicit Focus-on-Form

Two principal procedures:1. Request for clarification (i.e. Speaker A

says something that Speaker B does not understand; B requests clarification allowing A opportunity to reformulate)

2. Recast (i.e. Speaker A says something that Speaker B reformulates in whole or in part)

Page 24: Task based-language-teaching

An Example of an Implicit Focus on Form Learner: He pass his house. Teacher: He passed his house? Learner: Yeah, he passed his house.  Recasts provide learners with the opportunity to ‘uptake’ the correction but they do not always make use of it.

Page 25: Task based-language-teaching

Explicit Focus-on-Form

1. Explicit correction (e.g. ‘Not x, y’)2. Metalingual comment (e.g. ‘Not present

tense, past tense’)3. Query (e.g. ‘Why is can used here?’)4. Advise (e.g. ‘Remember you need to use

the past tense’).

Page 26: Task based-language-teaching

Example of Explicit Focus-on-FormLearner 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 one

Teacher: Found.Learner 2: I found one where I spoke with two English

women and we spoke about life in Canterbury or things and after I came backTeacher: Afterwards …(Seedhouse 1997)

Page 27: Task based-language-teaching

Pica’s research

Pica (2002) examined the extent to which learners and their teachers modified the interaction that arose in content-based instruction in order to attend to developmentally difficult form-meaning relationships (for example, English articles) - Pica reported very little attention to form.

She commented ‘one of the most striking findings of the study was that the majority of student non-target utterances went unaddressed in any way’ (p. 9). One reason for this was that the students’ utterances, although often ungrammatical, did not require any adjustment in order to be understood.

In other words, the interesting and meaningful content that comprised these lessons drew learners’ attention from the need to attend to form.

Page 28: Task based-language-teaching

Addressing the problem

Three ways: 1. Pica (2005) suggested that one way of addressing

this is to develop focused tasks (especially information-gap tasks) that direct learners’ attention to form.

2. Negotiation of form – i.e. teachers didactically address form even though no communication breakdown has occurred.

3. Reviewing the linguistic problems learners experienced in the post-task phase of the lesson.

Page 29: Task based-language-teaching

The Post-Task Phase

Three main options: Repeat performance Reflection on performance of the task Attention to form

Page 30: Task based-language-teaching

Repeat Performance

Research shows that when learners repeat a task their production improves in a number of ways (e.g. complexity increases, propositions are expressed more clearly, and they become more fluent).

A repeat performance can be carried out under the same conditions as the first performance (i.e. in small groups or individually) or the conditions can be changed.

Page 31: Task based-language-teaching

Reflecting on the Task PerformanceStudents present an oral or written report:- summarising the outcome of the task. - reflecting on and evaluating their own performance of the task. - commenting on which aspect of language use (fluency,

complexity or accuracy) they gave primacy to- discussing communication problems- reporting what language they learned from the task - suggesting how they might improve their performance of the

task.

Page 32: Task based-language-teaching

Attention to Form

Options include:- review of learner errors (‘proof listening’ –

Lynch)- CR tasks- Production practice- Noticing activities (dictation; making a

transcript)

Page 33: Task based-language-teaching

Some Problems and their Solutions

Page 34: Task based-language-teaching

Pedagogical problems Solutions

1. Students lack proficiency to communicate in the L2

Devise activities that develop ability to communicate gradually.

2. Students unwilling to speak English in class.

Use small group work; allow planning time; learner training

3. Students develop pidginized language system

Select tasks that demand fully grammaticalized language

Page 35: Task based-language-teaching

Educational problems Solutions

1. Emphasis on ‘knowledge’ learning

Review philosophy of education.

2. Examination system

Develop new more communicative exams

3. Large classes Use small group work; develop tasks suited to large classes.

Concluding comments

Page 37: Task based-language-teaching

Advantages of task-based teaching1. Task-based teaching offers the opportunity

for ‘natural’ learning inside the classroom.2. It emphasizes meaning over form but can

also cater for learning form.3. It is intrinsically motivating.4. It is compatible with a learner-centred

educational philosophy.5. It can be used alongside a more traditional

approach.
