The Effects of the Virtual Background on French as a Second Foreign Language Vocabulary Learning

Abstract

The purpose of this research was to investigate how the use of green screen technology affects vocabulary acquisition in LOTE (languages other than English) learners, particularly Chinese students learning French as a second foreign language. Two groups (a control group and an experimental group) with a total of 58 students participated in the study. Data were collected through in-class and delayed vocabulary tests, learning questionnaire, and semi-structured interviews. The study results demonstrate significant benefits in terms of providing an authentic learning experience, improving understanding, increasing motivation, and facilitating interaction. The results also confirm the technology’s effectiveness in enhancing both immediate and long-term vocabulary retention. The effectiveness is particularly evident for location-related words, as the technology provides visual context that facilitates recall of these words, which may not have easily retrievable mental images compared to more concrete words with tangible references. Further research can also be undertaken to compare the impact of virtual background on vocabulary retention with other immersive technologies. Nevertheless, virtual backgrounds are likely to be a cost-effective and accessible tool that can already offer promising improvements in learning outcomes and can be easily implemented with existing software like Zoom (5.2.0 or higher) and Tencent Meeting (1.3.0 or higher).
