Abstract

This study explored how aptitude and working memory affect second language (L2) learners' processing and incidental learning of technical vocabulary from a video-lecture-based task. Twenty-nine Chinese learners of L2 English performed the task, during which they watched an introductory lecture while taking notes. Eleven technical words presented in lecture diagrams were selected as target words. Participants' visual attention to the target words was captured using an eye-tracker. Following the task, participants completed an unannounced vocabulary post-test, a free recall test, and a set of aptitude tests. Two weeks after the treatment, a delayed vocabulary post-test and a battery of working memory tests were administered. Results from mixed-effects models revealed that working memory significantly predicted learners' learning of technical vocabulary. However, neither aptitude nor working memory emerged as significant predictors of learners’ visual attention to the target words.

在视频教学任务中，能力倾向和工作记忆在二语学习者技术词汇加工和附带学习中的作用

本研究探讨了能力倾向和工作记忆如何影响第二语言学习者对技术词汇的加工和附带学习。29名学习第二语言英语的中国学生参与了这项任务，在此过程中，他们一边看一段介绍讲座，一边做笔记。选取了11个讲座图中的专业词汇作为目标词汇。参与者对目标单词的视觉注意力是用眼动仪捕捉到的。任务结束后，参与者完成了一个未事先通知的词汇后测、一个自由回忆测试和一组能力倾向测试。治疗两周后，进行了延迟词汇后测和一系列工作记忆测试。混合效应模型的结果显示，工作记忆对学习者技术词汇的学习有显著的预测作用。然而，能力倾向和工作记忆都不是学习者对目标单词视觉注意力的重要预测因素。

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.
