Corrective Feedback in Second Language Acquisition

Corrective feedback refers to the responses learners receive to their linguistic errors during second language instruction or interaction. It encompasses explicit corrections, such as metalinguistic explanations, and implicit strategies, notably recasts, prompts or clarification requests. Research over the past decades has examined the timing (immediate versus delayed), modality (oral, written, computer-mediated) and focus (grammar, vocabulary, pronunciation) of feedback, revealing that effectiveness depends on the alignment of feedback type with learner readiness and task demands. From a sociocultural perspective, corrective feedback functions as a scaffold, mediating the learner’s movement from assisted performance towards autonomy. Interactional approaches emphasise negotiation of meaning and uptake—instances in which learners notice and incorporate feedback into subsequent production. Form-focused instruction situates corrective feedback within fluency tasks or dedicated practice activities, balancing communicative goals with form awareness. Advances in technology, including synchronous computer-mediated communication and AI-supported learning environments, have opened new avenues for adaptive, personalised feedback. Globally, these insights inform teacher training, classroom practice and digital tool design, ensuring that corrective feedback fosters linguistic accuracy without hindering learner confidence or communicative flow.

Corrective Feedback in Second Language Acquisition publication trend

The graph below shows the total number of articles in corrective feedback in second language acquisition across all publications each year (not limited to Nature Index journals).

Technical terms

Recast: Implicit reformulation of a learner error without overtly drawing attention to the mistake.

Prompt: A feedback strategy that encourages the learner to self-correct, often through questions or incomplete reformulations.

Uptake: Learner response immediately following feedback that demonstrates noticing or use of the corrected form.

Metalinguistic feedback: Explicit commentary on the nature of the error, often referring to grammatical rules or language forms.

Focus on form: Instructional episodes that draw learners’ attention to linguistic features within a communicative context.
