Given the small body of existing research concerning focus on form at post-task stage in task-based language teaching, the present study adopts post-task transcribing as a focus on form activity and explores the effects of transcribing under various conditions. In addition, two task types are adopted in multiple task sessions to explore task effects and task practice effects on learners' oral performance. / Ninety-six participants, divided into five experimental groups and one control group completed four tasks with a one-week interval between each task. Different experimental groups were assigned various post-task activities respectively. No post-task activity was adopted in the control group. Task performance was measured in terms of complexity, accuracy, fluency and lexical performance. / The findings are multifaceted. First of all, the adoption of post-task transcribing was found to be efficient for different formal aspects of task performance. In the second place, the pair-based transcribing brought about more syntactically complicated language, whereas the individual condition at the post-task stage led to an improvement in lexical sophistication. Thirdly, further revision after transcribing had complex effects on accuracy and complexity. Fourthly, interactive tasks proved to be more promising for a better overall task performance. Last but not least, multiple task practices were found to be beneficial for learners' lexical performance. / The findings were discussed in light of the concept of noticing and attention, Levelt's speaking model, socio-cultural theory and other related SLA theories. Based on the theoretical discussion, pedagogical implications have been proposed. / This research argues that in task-based language teaching, more attention should be paid to the post-task stage regarding its effect on focus on form. Specifically, it suggests that (a) a post-task transcribing activity can be adopted as a feasible focus on form activity in L2 classrooms; (b) different conditions for the operation of post-task transcribing may bring about distinct effects on various aspects of task performance; (c) different task types have different effects on learners' performance; (d) multiple task sessions are necessary for L2 language improvement. Further, the present study calls for a process-product approach in further studies concerning the effects of post-task focus on form activities. / Li, Qian. / Adviser: Peter Skehan. / Source: Dissertation Abstracts International, Volume: 73-03, Section: A, page: . / Thesis (Ph.D.)--Chinese University of Hong Kong, 2010. / Includes bibliographical references (leaves 254-278). / Electronic reproduction.
