Investigating the effectiveness of bio-feedback techniques in improving English vocabulary learning in ESL learners.

This study investigated the effectiveness of bio-feedback techniques in improving English vocabulary learning in ESL learners. Bio-feedback is a technique that provides real-time information about an individual's physiological responses to external stimuli. In this study, bio-feedback was used to measure changes in skin conductance level (SCL) in response to English vocabulary learning tasks. The participants were 30 ESL learners from a language center at a university in China. They were randomly assigned to either an experimental group, which received bio-feedback during English vocabulary learning tasks, or a control group, which did not receive bio-feedback. Both groups received the same vocabulary learning tasks and were evaluated based on a pre-test and post-test design. The results showed that the experimental group had significantly higher improvement in English vocabulary learning than the control group. The findings suggest that bio-feedback techniques can be an effective tool in improving English vocabulary learning in ESL learners. Future studies could investigate the underlying physiological and psychological mechanisms of bio-feedback in English vocabulary learning and explore the potential of integrating bio-feedback into language learning technology.
