To address the challenges of limited language proficiency and provide necessary feedback in the implementation of task-based language teaching (TBLT), a mobile-supported TBLT application was developed to provide linguistic and task scaffolding. Sixty-six English as a foreign language (EFL) university learners participated in a three-week experiment as part of a general English course. They were assigned to either an experimental group (mobile-supported TBLT), which received TBLT with scaffolds built into the application, or a control group (traditional TBLT), which received traditional paper-based TBLT without the scaffolds. At the end of the experiment, an English achievement test of vocabulary, grammar, and conversation comprehension was administered to determine if the technological scaffolds enhanced the learning outcomes for the course. Students’ self-perceived use of oral communication strategies was also measured to explore how these scaffolds affected the conversational interaction essential for task performance. Results showed that the mobile-supported TBLT group outperformed the traditional TBLT group on the vocabulary and conversation comprehension tests but not so much on the grammar test. Also, the mobile-supported TBLT group reported greater awareness of fluency- and accuracy-oriented strategies for speaking than the traditional TBLT group. Implications for designing mobile learning to enhance TBLT in an EFL setting are drawn.

移动支持的任务型语言教学对EFL学生语言成绩和会话互动的影响

为了解决语言能力有限的挑战并在基于任务的语言教学 (TBLT) 的实施中提供必要的反馈，开发了一个移动支持的 TBLT 应用程序来提供语言和任务脚手架。作为普通英语课程的一部分，六十六名英语作为外语 (EFL) 大学学习者参加了为期三周的实验。他们被分配到实验组（移动支持的 TBLT），接受 TBLT 并在应用程序中内置支架，或对照组（传统 TBLT），接受传统的纸质 TBLT，没有支架。在实验结束时，对词汇、语法和对话理解进行了英语成绩测试，以确定技术支架是否提高了课程的学习成果。还测量了学生对口头交流策略的自我感知使用，以探索这些支架如何影响对任务执行至关重要的对话互动。结果表明，移动支持的 TBLT 组在词汇和会话理解测试上优于传统的 TBLT 组，但在语法测试上则不如传统 TBLT 组。此外，与传统的 TBLT 组相比，支持移动设备的 TBLT 组报告了对流利度和准确性为导向的口语策略的更高认识。绘制了设计移动学习以增强 EFL 设置中的 TBLT 的含义。结果表明，移动支持的 TBLT 组在词汇和会话理解测试上优于传统的 TBLT 组，但在语法测试上则不如传统 TBLT 组。此外，与传统的 TBLT 组相比，支持移动设备的 TBLT 组报告了对流利度和准确性为导向的口语策略的更高认识。绘制了设计移动学习以增强 EFL 设置中的 TBLT 的含义。结果表明，移动支持的 TBLT 组在词汇和会话理解测试上优于传统的 TBLT 组，但在语法测试上则不如传统 TBLT 组。此外，与传统的 TBLT 组相比，支持移动设备的 TBLT 组报告了对流利度和准确性为导向的口语策略的更高认识。绘制了设计移动学习以增强 EFL 设置中的 TBLT 的含义。
