Implication

Controlled trial demonstrates improved speaking ability and enjoyment with reduced anxiety in university EFL learners, highlighting the benefits of AI-supported adaptive learning.

Key Points

To investigate the longitudinal effects of pedagogically guided, AI-mediated informal digital English learning on the speaking performance, anxiety, and enjoyment of university foreign language learners.
Assigned 89 Chinese university English as a foreign language (EFL) students to either an experimental group receiving a 12-week AI-mediated intervention or a control group.
Evaluated standardized speaking skills and administered validated questionnaires on speaking anxiety and enjoyment at pre-test, post-test, and a 10-week delayed post-test.
Analyzed longitudinal changes across groups over time using mixed-effects modeling (MEM).
The experimental group demonstrated significantly greater gains in English speaking ability at post-test compared to the control group.
Participants engaging in the AI intervention experienced significantly higher speaking enjoyment and greater reductions in speaking anxiety relative to controls.
