This study uses a complexity-accuracy-lexis-fluency (CALF) framework to explore performance on 2 speaking tasks: a narrative picture-based task and an interactive decision-making task. A preliminary aim is to compare performance on the 2 tasks, using a wide range of CALF measures to explore where scores are similar and where they are different.…

The concept of focus on form has been influential in second language (L2) acquisition and pedagogy. One example of the implementation of focus on form is a post-task activity (e.g., anticipation of a public performance) that can selectively orient learners toward increased levels of accuracy. The present research proposes a new operationalization…

This chapter will present a research synthesis of a series of studies, termed here the Ealing research. The studies use the same general framework to conceptualise tasks and task performance, enabling easier comparability. The different studies, although each is self-contained, build into a wider picture of task performance. The major point of…

Complexity, accuracy, and fluency have proved useful measures of second language performance. The present article will re-examine these measures themselves, arguing that fluency needs to be rethought if it is to be measured effectively, and that the three general measures need to be supplemented by measures of lexical use. Building upon this…

Explored the effects of inherent task structure and processing load on narrative retelling task performance, analyzing task performance in terms of competition among fluency, complexity, and accuracy. Research with young adults found that degree of inherent task structure more strongly affected fluency of performance. Processing load influenced…

Given recent claims that task-based instruction has desirable pedagogic qualities, this article investigates the effects of choosing different types of tasks, as well as different task implementation conditions, on the fluency, accuracy, and complexity of the language that is produced when tasks are carried out.

Examines proposals for task-based approaches to instruction, reviews relevant research, investigates developments in cognitive psychology, proposes a framework for the implementation of task-based instruction drawing upon relevant theory, and organizes the methods to implement such instruction so as to minimize problems and maximize goal…
