The Claim
Immediate corrective feedback from an LLM chatbot during conversational practice increases users' perception of the chatbot's effectiveness for language learning compared to delayed feedback, as measured by a statistically significant mean difference of 0.57 on a 7-point scale (p=0.0495, Cohen’s d=0.56) among 54 adult L2 English learners over a one-month period.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Adults learning English as a second language who receive immediate corrections from an LLM chatbot during conversation report higher perceived effectiveness of the chatbot than those who receive delayed corrections, based on a measurable difference in survey scores.
See the scientific wording
Immediate corrective feedback from an LLM chatbot during conversational practice improves users' perception of the chatbot's effectiveness for language learning compared to delayed feedback, as evidenced by a statistically significant increase in perceived effectiveness scores (mean difference: 0.57 on a 7-point scale, p=0.0495, Cohen’s d=0.56) among 54 adult L2 English learners over a one-month period.
When a person receives a correction right after making a language mistake, the brain detects the mismatch between what was said and what was intended, which activates areas that track errors and reward learning. This immediate signal strengthens the connections involved in producing correct language, making the person feel the tool is more useful.
What the research says
1 studyWhen learners get grammar corrections right away while talking to an AI chatbot, they feel like the chatbot is more helpful than when corrections come later. This study found that people liked the chatbot better when it corrected them immediately.
