Abstract

Task repetition (TR) is a well-researched construct in task-based language teaching (TBLT), recognized for its potential to enhance Complexity, Accuracy, Lexical Complexity, and Fluency (CALF) in second language (L2) oral production. This study meta-analyzes the growing body of research in this area to examine the overall effect of TR on L2 oral CALF and the role of moderator variables. Findings reveal that TR has a substantial impact on syntactic complexity and accuracy, with learners producing more complex and less erroneous utterances. Fluency and lexical complexity, while positively influenced by TR, exhibit smaller gains, suggesting that TR primarily enhances structural aspects of language. Moderator analyses indicated that factors such as learning context, task type, type of TR, and spacing interval influence the effectiveness of TR: Larger effects for syntactic complexity, accuracy, and fluency were observed in foreign language contexts than in second language contexts; narrative tasks and exact repetition were particularly effective in enhancing syntactic complexity; longer spacing intervals were associated with smaller effects on syntactic complexity and fluency. The study offers valuable pedagogical insights for optimizing TBLT practices to enhance L2 oral production.

任务重复与第二语言口语表现：一项元分析

任务重复（Task repetition， TR）是任务型语言教学（Task -based language teaching， TBLT）中一个被广泛研究的结构，它被认为具有提高第二语言口语表达的复杂性、准确性、词汇复杂性和流利性（CALF）的潜力。本研究荟萃分析了该领域越来越多的研究，以检验TR对第二语言口语CALF的总体影响以及调节变量的作用。研究结果表明，训练对句法复杂性和准确性有实质性的影响，学习者会产生更复杂、更少错误的话语。流利性和词汇复杂性虽然受到训练的积极影响，但表现出较小的增益，这表明训练主要增强了语言的结构方面。调节因子分析表明，学习语境、任务类型、翻译类型和间隔等因素影响翻译效果：外语语境对句法复杂性、准确性和流畅性的影响大于二语语境；叙述性任务和精确重复在提高句法复杂性方面特别有效；较长的间隔时间对句法复杂性和流畅性的影响较小。该研究为优化任务型教学实践以提高第二语言口语水平提供了有价值的教学见解。

期刊介绍： This international journal is devoted to the applications of educational technology and applied linguistics to problems of foreign language teaching and learning. Attention is paid to all languages and to problems associated with the study and teaching of English as a second or foreign language. The journal serves as a vehicle of expression for colleagues in developing countries. System prefers its contributors to provide articles which have a sound theoretical base with a visible practical application which can be generalized. The review section may take up works of a more theoretical nature to broaden the background.
