The Impact of Chatbots Based on Large Language Models on Second Language Vocabulary Acquisition

To examine the impact of generative chatbots on Large Language Models on Second Language Vocabulary Acquisition. In this study, 52 English as a Foreign Language (EFL) students were randomly assigned to two groups: one with the assistance of a Chatbot based on Large Language Models and one without. Both groups learned the same series of target words over eight weeks. Post-treatment assessments, including systematic observation and quantitative tests assessing both receptive and productive vocabulary knowledge, were administered immediately after the study and again two weeks later. The findings demonstrate that employing an AI Chatbot based on Large Language Models significantly aids students in acquiring both receptive and productive vocabulary knowledge during their second language learning journey.

Data pertain to the interactions with the chatbot, while assessment includes data from the pre-assessment, post-assessment, and delay assessment.
