Description¶
The article's theoretical framework presents Swain's output hypothesis, which assigns production of language a significant role in second-language acquisition alongside comprehensible input. It identifies three functions: a hypothesis-testing function, a metalinguistic function, and the noticing/triggering function, in which "learners may notice a gap between what they want to say and what they can say". The study tests the third function in EFL writing.
Design Implications¶
Context¶
Requirements¶
- Production of the target language under circumstances that push learners to generate output
Constraints¶
- The noticing function operates "under some circumstances", per the quoted Swain passage
Target Learners¶
- Second-language learners, here an adult EFL learner
Target Learning Objectives¶
- Second-language writing, lexis and grammar
Claims¶
- Output Noticing Predominantly Lexical [+M]
- Rewriting Solves More Lexical Gaps [+M]
- Comprehensible input alone is insufficient for acquisition of high levels of grammatical proficiency [+W]
- Notetaking as a feedback tool facilitates resolution of lexical problems but leaves grammatical problems unresolved, suggesting reformulation as an alternative [+W]
- Comparing original texts to model paragraphs prompted noticing that was again focused on lexical features [+W]
Related Theories¶
- Swain's Comprehensible Output Hypothesis with a circular input-output-intake model
- Ellis's revised interaction hypothesis: noticing, comparison, and integration as the basic acquisitional procedures
- Output-driven, input-enabled hypothesis: output as both driving force and objective of EFL teaching
- Swain's output hypothesis — the canonical page for this theory
Examples¶
- Give students more chances to produce output and communicate during writing, with varied assignment types and clear sufficient feedback
- Three-stage writing task: write with problem notes, compare to a model paragraph, then rewrite
