The Influence of Planning and Task Type on Second Language Performance

This study focuses on the impact of different variables on the nature of language performance in the context of task-based instruction. Characteristics of tasks are discussed, and then a framework is offered that can organize the nature of task-based instruction and relevant research. The framework is used to generate predictions regarding the effects of three different tasks (Personal Information Exchange, Narrative, and Decision-Making) and three different implementation conditions for each task (unplanned, planned but without detail, detailed planning) on the variables of fluency, complexity, and accuracy. The study reports strong effects of planning on fluency and clear effects also on complexity, with a linear relationship between degree of planning and degree of complexity. However, a more complex relationship was discovered between planning and accuracy, with the most accurate performance produced by the less detailed planners. In addition, interactions were found between task type and planning conditions, such that the effects of planning were greater with the Narrative and Decision-Making tasks than with the Personal Information Exchange task. The results are discussed in terms of an attentional model of learning and performance and highlight the importance of tradeoff effects between the goals of complexity and accuracy in the context of the use of limited capacity attentional resources. The study contributes to the development of cognitive models of second language performance and addresses a number of pedagogic issues.

Task-Based Instruction.

In the last twenty years or so, language teaching has changed to incorporate a higher proportion of meaning-based activities, in contrast to the era in which form was primary and a concern for meaning only followed the establishment of control over specific forms. Now, a wide range of classroom options are available for participant organization, content incorporation, and the units by which teaching is organized. In order to locate task-based work within such a range of options, it is necessary to address definitional issues at the outset, since many different contemporary options give task a central role. For the purposes of this chapter, a task is regarded as an activity which satisfies the following criteria:

The influence of task structure and processing conditions on narrative retellings

This article explores the effects of inherent task structure and processing load on performance on a narrative retelling task. Task performance is analyzed in terms of competition among fluency, complexity, and accuracy. In a study based on 47 young adult low-intermediate subjects the fluency of performance was found to be strongly affected by degree of inherent task structure; more structured tasks generated more fluent language. In contrast, complexity of language was influenced by processing load. Accuracy of performance seemed dependent on an interaction between the two factors of task structure and processing load. We discuss which aspects of performance receive attention by the language learner. The implications of such cross-sectional results for longer term language development are considered.

The influence of source of planning and focus of planning on task-based performance

Recent research (Crookes, 1989: Foster and Skehan, 1996) has focused on the role of planning when tasks are used within language instruction. These studies have indicated that pre-task planning can have beneficial effects upon the nature of task performance, consistently leading to greater fluency and complexity and, less dependably, greater accuracy. The present study examines different sources of planning (teacher-led, solitary, group-based) as well as different foci for planning (towards language or towards content). Using a decision-making task (a ‘balloon debate’), data was collected using a 2×2 research design contrasting source of planning (teacher-led, group) and focus of planning (language vs content). In addition, to ensure comparability with previous research, solitary planning and control groups were also used. Results indicate a number of statistically significant effects. The teacher-fronted condition generated significant accuracy effects, while the solitary planning condition had greater influence on complexity, fluency and turn length. Group-based planning did not lead to performance significantly different from the control group. Finally, there was little effect on performance as a result of the language vs content planning condition. The results are discussed in relation to how teachers may more effectively make pedagogic decisions on task implementation conditions linked to selective pedagogic goals.

Task-based instruction

This article is organised in five main sections. First, the sub-area of task-based instruction is introduced and contextualised. Its origins within communicative language teaching and second language acquisition research are sketched, and the notion of a task in language learning is defined. There is also brief coverage of the different and sometimes contrasting groups who are interested in the use of tasks. The second section surveys research into tasks, covering the different perspectives (interactional, cognitive) which have been influential. Then a third section explores how performance on tasks has been measured, generally in terms of how complex the language used is, how accurate it is, and how fluent. There is also discussion of approaches to measuring interaction. A fourth section explores the pedagogic and interventionist dimension of the use of tasks. The article concludes with a survey of the various critiques of tasks that have been made in recent years.

Lexical performance by native and non-native speakers on language learning tasks

The last 20 years or so have seen a vast increase in research into second language learning tasks. A series of articles has been published by this author and co-researchers taking a cognitive approach to task performance (Foster, 2001a; Foster and Skehan, 1996, 1999; Skehan and Foster, 1997, 1999, 2005, 2007). This chapter reports on a meta-analysis of these studies (see also Skehan and Foster, 2007), but it does so with two additional foci. First, most research with tasks has focused only on second language learners. As a result, it is difficult to disentangle whether performances which are reported are the result of the different variables which are being manipulated (e.g. task characteristics, task conditions) or simply the second language speakerness of the participants. One needs baseline native-speaker data, of the sort reported in Foster (2001a), to enable a better perspective on the results to be obtained.

Tasks Versus Conditions: Two Perspectives on Task Research and Their Implications for Pedagogy

ABSTRACT This chapter explores the contrast between the effects on second language performance of tasks and task characteristics, on the one hand, and the conditions under which tasks are done, on the other. The first major section explores the evidence on this issue and proposes that the impact of conditions such as pretask planning, task repetition, and posttask activities is greater and more consistent than the impact of tasks and features such as time perspective or number of elements. The second major section explores the theoretical accounts that have been proposed regarding tasks and conditions. It is suggested that deductive accounts have, so far, only had limited success regarding the use of tasks, but that psycholinguistic models of speaking do provide a looser but more useful framework to account for the effects of conditions. It is also suggested that an important difference between tasks and conditions concerns the tension between constraint and flexibility in performance and that the flexibility provided by task conditions is an important component in the more dependable results they have generated. Finally, pedagogic implications are discussed linking task conditions to the methodological choices that are available to teachers.

Language Instruction Through Tasks

The chapter provides a survey of research into task-based foreign language instruction, spanning the last twenty years or so. At the outset, it contextualises task research within communicative approaches to language teaching, and argues that optimistic interpretations of communicative activities as vehicles for language development lack research support. Task instruction research is then linked to a more realistic underlying account stressing a Focus-on-Form. Subsequently, four perspectives on task research are discussed: a psycholinguistic approach to interaction; a cognitive approach to attentional use during tasks; a sociocultural perspective; and the use of focused tasks. The first emphasizes the quality of feedback that can be generated by well-designed interactions. The second explores how different task characteristics and task conditions influence attentional demands, and the scope there is to direct attention to form without compromising meaningful communication. The third explores how task participants collaborate on tasks and reinterpret them as they are being completed. Finally, the fourth approach examines whether it is possible to “seed” tasks with particular language structures without losing the benefits of a primacy for meaning. After the different perspectives have been described, they are compared with one another. Next, a series of controversies within the task literature are examined and the chapter concludes by proposing some future directions for task instruction research.

Individual Differences in Second-Language Learning

This article is broadly concerned with the differences between individual language learners. In terms of particular content areas of Individual Differences (ID) research, it surveys developments in foreign language aptitude, motivation, learner strategies, and learner styles. A brief review of earlier research on aptitude is presented, followed by discussions of more contemporary work on the origin of aptitude, namely, as a residue of first language learning ability, and on the existence of evidence for “learner types.” Motivation research is reviewed partly with regard to Robert Gardners research, and then in terms of a wider framework for the functioning of motivation within an educational context. The review of learner strategies research emphasizes current attempts to develop taxonomies of such strategies, and to investigate their theoretical basis and their trainability. Finally, learner styles research, drawing on field independence theory, is discussed, and links are made with the research on aptitude. The article finishes with sections on conceptual and methodological issues in ID research.

Ladders and Snakes in Second Language Fluency

Abstract This article reports a study comparing first and second language fluency during narrative retelling tasks of varying degrees of tightness in structural organisation, exploring in particular a distinction between discourse-based and clause-based fluency. We argue that positive and negative influences on fluency are linked to the Conceptualiser and Formulator stages of Levelt’s model of speaking. Task structure and degree of subordination, which were related to greater fluency for both native and non-native speakers, are Conceptualiser and discourse oriented. Formulaic language, which was also related to fluency, is more Formulator and clause oriented. Contrastingly, higher lexical sophistication and longer clauses are associated with clause-linked fluency problems, but only for native speakers.
