Free ebooks ==> www.ebook777.com Series editors’ preface to Volume It is our pleasure to introduce the fifth volume in this series, a collection edited by Peter Skehan and entitled Investigating a Processing Perspective on Task Performance This book is in many ways a culmination of work initiated by Skehan some two decades ago, as it builds upon the theoretical perspectives of his Tradeoff Hypothesis and extends from the considerable associated research into task types, characteristics, and implementation conditions Of primary interest in this volume is the relationship between task design variables and their effect on how language learners produce speech for communicative purposes Tasks here are generally brief spoken narratives of the sort that have grown in popularity as primary pedagogic tools of task-based instruction that seeks to provide a focus-on-form and – meaning simultaneously Beyond their apparent face value as opportunities for practicing L2 speech and developing fluency, such tasks offer the intriguing possibility of drawing learners’ attention to form-­meaning connections, initiating learner analysis and restructuring of their interlanguage, improving their control of the language, and ultimately pushing the development of language knowledge and proficiency The main goal here is for learners to be able to produce complex, accurate, and fluent L2 speech, with tasks being employed to integrate the various learning processes; and the key question then is “how?” Beginning in the early 1990s, and presented first in an influential article “A framework for the implementation of task-based instruction” followed by the highly cited book A Cognitive Approach to Language Learning, Peter Skehan proposed that learner performance on these kinds of tasks was determined in part by the fundamentally limited cognitive resources that a person has available during speech Telling a story, describing a picture, explaining a process – these tasks consume the attention that learners have at their disposal, and which, as a consequence, needs to be divided between fluency, accuracy and complexity of their performance In this respect, certain tasks have been claimed to make greater or lesser demands on cognition; in a similar vein the conditions under which learners are asked to perform tasks may influence what they focus on in their production For example, providing learners with the opportunity to plan prior to telling a story may free up attentional resources, resulting in spoken narratives that are lexically more diverse, syntactically more complex, grammatically more accurate, and so on Building from these observations into pedagogic implications, Skehan advocated for cycles of tasks that were selected, designed, and sequenced to intentionally shift learners’ attention between a focus on fluent and efficient communication versus the opportunity to restructure and ‘push’ language production at the cusp of interlanguage development Skehan’s groundbreaking ideas, along with the competing theoretical position of Peter Robinson’s Cognition Hypothesis (see volume in the TBLT:IRP series), inspired Free ebooks ==> www.ebook777.com 252 Peter Skehan that much of the previous discussion on tasks is relevant We have seen (and this is captured in Table 2) that a whole range of influences enhance levels of accuracy and fluency In effect, these are the conditions which are needed to make the development of greater control a reality So, for example: –– –– –– –– opportunity for supported on-line planning familiar information opportunity to repeat tasks post-task activity, especially with revision are all very important here By choosing tasks which maximise accuracy and fluency, and task conditions likewise, the learner is being supported to achieve greater levels of control This can assist first stages in making the transition from halting speech production to the capacity to use language in real-time In effect we are dealing here, more generally, with either creating tasks and conditions for more attentional resources to be available for the speaker, so that greater accuracy, for example, can be achieved; or for tasks and conditions to push learners to higher performance in particular areas, again highlighting accuracy; or for a situation where attention is ‘nudged’ in particular directions So knowledge of research into second language production is relevant to helping learners to follow desirable pedagogic directions An important point needs restating here It is clear that the use of tasks in this way draws on the importance of implicit learning and even of practice, since the learner is being given (supportive) opportunities to gain control over language We are now beyond the stages where new language has been noticed, complexified, integrated, and instead are concerned with making this newly-acquired knowledge implicit A proponent of a presentation-practice-production (3Ps) approach might then claim that this view of tasks is no different from the role ascribed to them by task critics such as Swan (2005) or Bruton (2002), or even task sympathisers such as Littlewood (2004) The key point, though, is the issue of what language is being used, and that in turn connects with the issue of pre-selection A 3Ps approach is characterised by selections being made by the teacher/materials writer, and then the presentation phase is a phase working on something selected by someone other than the learner A task approach is one where the language which was earlier selected for treatment was selected by the learner or emerged from learner performance The use of task-informed criteria here to promote control is consistent with this view that the selection comes from the learner There is no pre-selection of forms for task performance – that is the learner’s choice The decisions linked to task selection and task implementation are intended to create conditions to support control of the language which is chosen by the learner In fact, developing this point, we can return to the usefulness of the post-task stage Where the language that is being focussed on has emerged from the learner, there is no reason, if a teacher deems this appropriate, for the post-task stage not to www.ebook777.com Limitedebooks attentional capacity, second www.ebook777.com language performance, and task-based pedagogy Free ==> include practice activities So far we have regarded this stage as one where noticing, hypothesising, complexifying, and restructuring generate a fairly cognitive view of language itself, of its patterns and of the emerging rule-governed system, but developing language skill, as we all know, involved more than insight and understanding It also involves performance, and if a teacher decides that some aspect of language is emerging, but could benefit from more traditional practice activities, then there is no reason not to use them at this later stage in a teaching sequence The point, a bit laboured by now, is only that what is being practised is a response to learner need, not syllabus prescription Continuing this analysis of tasks in terms of the development of control, the next two stages are essentially extensions of what we have already seen Automatising, following Anderson (2004), consists of speeding up performance while eliminating error Supported control, the previous stage, is likely to be characterised by slow performance, and the intrusion of errors Automatisation does not really involve much that is different but it does lead to a greater degree of confidence in performance, and even robustness in face of contextual difficulties With tasks, a similar analysis operates A range of influences are relevant in creating the conditions in which automatisation is more likely to occur, and in some ways, these are an extension of what was mentioned with supported control But another factor which is important is, in a sense, the reverse argument Choosing tasks and task conditions to nurture automatisation is one thing, but it does not serve learners if they only develop the capacity to use language in supportive conditions So another goal, where automatisation is concerned, is to choose tasks and task conditions to put pressure on learners so that they feel more comfortable functioning in the wider range of circumstances they will encounter in the real world So automatisation here is a speed factor, but also a generalisation challenge, which can only be attempted when some degree of automatisation has been achieved The final stage which is given here is lexicalisation This stage is proposed (­Skehan 1998) to reflect a dual-mode system in which on the one hand we can use rule-based language produced quickly as highly automatised, or on the other, the products of such rule-based language can be lexicalised and then produced as exemplars or chunks Such a mode enables not simply speed of processing but also the advantage that there are not many computational demands, so that attention is, to some extent, is freed up while performance is ongoing (Skehan 2013) Clearly using tasks is compatible with fostering fluency on the basis of lexicalisation Using tasks which support Formulator operations, for example, will help in any process of lexicalisation that might occur But in all truth, it is likely that it is asking too much of tasks to expect them to contribute significantly to any such process Of course they will much more than many other teaching methodologies, but the amount of communication that is necessary for any process of lexicalisation to occur is probably too great for any task-based approach to deliver There simply is not enough 253 Free ebooks ==> www.ebook777.com 254 Peter Skehan time for things to develop in this way Lexicalisation is a desirable goal, but one that probably can only be achieved by long and extensive exposure to the target language in question Task-based syllabuses developed to cover several years may achieve this, although such a claim is currently speculative Shorter-term task use would struggle to achieve wide-ranging lexicalization The sequence which has just been described starts with the new, with something that is perhaps not understood completely and is used haltingly and sometimes incorrectly, to a point where the formerly new language is now well-integrated into a developing system and can be used, in real-time fluently and correctly, and even without undue processing effort But there is another aspect of the sequence which we have temporarily left out and now needs further consideration This is the issue of saliency or repertoire creation, what in French can be referred to as disponibilité The previous discussion has assumed there is some aspect of the language system and its choice for use is self-evident – if something is known, it will be used But such an approach misses a very important point about language learning – one may know a great deal of language that one does not use So in addition to trying to teach new things, a goal of teaching has to be to increase the access that the learner has to what is known, but whose relevance and usefulness may not be appreciated In other words, if learners have found methods of solving communicative problems which are not pretty, or helpful for development, but are nonetheless effective, they may learn new aspects of the target language, but not use them They may plateau at a certain, unnecessary level because they can get by using older methods of solving problems So the teaching challenge is not simply to introduce new forms effectively, but also to get those new forms to supplant older language or at least to become part of a communicative repertoire For this goal, a task-based approach is very well suited Tasks, especially tasks which are reflected upon afterwards, can support learners to develop such a repertoire, and for them to see how what has been learned has communicative utility In this case, the range of variables which have been shown to influence performance can be related to the promotion of accessibility The emphasis here will be on Formulator operations, rather than Conceptualisation, so that either attention is made more available when the surface structure of language is being put in place, or there is a focus on accuracy to some degree (e.g through post-task activities, or through monitoring) These can make it more likely that the newer forms will not be there for a rainy day, so to speak, but have sufficient salience that they can become usable even in more difficult circumstances Principles for using a task-based approach The last section has tried to clarify the pedagogic contributions that a task-based approach can uniquely make The section, though, was driven by the sequence of what www.ebook777.com Limitedebooks attentional capacity, second www.ebook777.com language performance, and task-based pedagogy Free ==> happens during acquisition In addition to such an account, it is also useful to have a set of principles for the use of tasks over a more extensive timescale, ranging over several lessons, or even a period as long as one term In Skehan (1998), I put forward five principles for a task based approach The five principles were: Choose a range of target language elements1 Choose tasks which meet Loschky and Bley Vroman’s (1993) utility criterion Select and sequence tasks to achieve balanced goal development Maximise the chances of a focus on form through attention manipulation Use cycles of accountability What this set of principles tried to address is the tension between two statements: Second language acquisition demonstrates that internal factors have a strong influence on patterns of development, such that learners not necessarily learn what teachers teach vs Some degree of system and completeness in what is being learned is preferable The principles tried to strike a balance between these two statements Unrestrained applications of a task-based approach based on relatively brief speaking tasks would risk over-valuing the first statement at the expense of the second Applications of traditional approaches would risk over-valuing the second at the expense of the first So, if one regards the first two principles above as somewhat preliminary, the third and the fourth attempt to nudge learners towards a focus-on-form, and the fifth, final, and very important principle suggests that teachers have an important role in monitoring the development of their students and designing pedagogic activities which deal with the lacunae in learning, and orient the input (e.g through pre-task work, task selection) towards areas which have not been developed But there is vagueness in these principles, and I would like to modify these proposals slightly First, I would now add to the third and fourth principles a set of subprinciples These are: –– –– –– –– –– complexifying pressuring easing focussing monitoring .  This proposal is not driven by any precept based on learners’ functional needs (such as Long & Crookes 1992) It could accommodate such an approach, but in fact offers greater freedom to the teacher or course-designer regarding the basis for task choice 255 Free ebooks ==> www.ebook777.com 256 Peter Skehan In other words, to make the general principles more accessible, I would suggest using the sorts of outcomes captured in Table 2, based as this table is on a range of empirical results, to make more specific the sorts of things that could promote balanced goal development, and a strong focus on form We have learned quite a lot from research as to how a general focus on form can be promoted So the principles are not quite so abstract now as they were when first proposed in 1998, and the claims follow from a range of research results Second, I would also like to add a new principle, and ideally place it as a new fifth principle (pushing the old last principle, use cycles of accountability) down to sixth position The new principle would be: Use the post-task phase to nurture language made salient by the task, through: –– –– –– –– explanation extension integration practice and consolidation As we have seen in earlier discussion, the post-task phase is vital as the place to capitalise on the language which has been made salient by the task The language which emerges in the task is the language which is relevant to learners But the operations on that language orchestrated by the teacher can enable the sixth principle, the use of cycles of accountability, to function more effectively Because it is here that the teacher can select from the range of language made salient that particular language which it is most propitious to work on, safe in the knowledge that it will be learner-led language This may be developmental language, or it may be language which needs further consolidation and practice It could even be new language, in the sense that a task may have created a need to mean, and then the teacher can supply that need in a focussed manner This is quite a challenge for the teacher Learners differ; experiences differ As a result, there may be a range of candidate language elements to pick up on at the post-task stage, not all of which can receive focus It is reliant on the teacher’s professionalism and training which of these to work with, which to defer until possibly later, and which to ignore We can now represent the set of principles in a more complete, comprehensive form: Choose a range of target structures Choose tasks which meet Loschky and Bley Vroman’s utility criterion Select and sequence tasks to achieve balanced goal development through –– complexifying –– pressuring www.ebook777.com Limitedebooks attentional capacity, second www.ebook777.com language performance, and task-based pedagogy Free ==> –– easing –– focussing –– monitoring Maximise the chances of a focus on form through attention manipulation through –– complexifying –– pressuring –– easing –– focussing –– monitoring Use the post-task phase to nurture language made salient by the task, through: explanation extension integration practice and consolidation Use cycles of accountability So far, we have taken what could be considered to be a micro stance towards pedagogy Sub-principles for and concern relatively small-scale tasks, and the task cycle that is envisaged here would be completed with one or two lessons (and could be broadly similar to the methodology proposed by Willis & Willis 2007) But teaching extends over more than just a short time span, obviously, and so, if pedagogic planning is to be effective, it needs to have means of organising these longer stretches of time Project work is one such method of linking a series of tasks in ways that retains the focus on meaning that tasks provide, but at the same time is susceptible to longer stretches of planned teaching Projects, and series of projects, can be designed to occupy long stretches of teaching But if that is done, the post-task work which has been described so far needs to be conceptualised slightly differently, since it is here that the sixth principle becomes important ‘Micro’ post-task work takes what has emerged from a task or group of tasks, and responds to the needs and opportunities which emerge (Principle 5) In a sense, the teacher’s decision is to examine what is available, what has become salient through the task, and from the range of possibilities, choose those which would sensibly be worked on If, though, one has more extensive task based performances to work with, which extend over time, then there is the need to keep records, explore what has been achieved over longer timespans by particular learners, and make decisions accordingly, decisions which can be collaboratively negotiated and made with students In other words, the notion of using cycles of accountability, where responsibility is shared between learners and teachers, becomes more important It can become clearer, with reflective post-task work of this sort, where there are still gaps and what needs to be focussed on in the future The broad parameters of learners not necessarily learning what teachers teach still apply, but the reflection can 257 Free ebooks ==> www.ebook777.com 258 Peter Skehan give insights as to what tasks might best be chosen and how they might be exploited In this way, the need to ensure some degree of systematicity is enhanced very considerably, and we have a bridge between micro and macro perspectives on tasks References Anderson,
