Subclaims¶

q2 i? Vocabulary can be acquired subconsciously while receiving comprehensible input, and this incidental acquisition outperforms intentional (conscious, tool-supported) learning in effectiveness per unit of time and in retention. → Ponniah 2011

q2 · i? · review · r1

Narrative review of incidental vocabulary acquisition research (Krashen 2004; Lee 2009; Kweon & Kim 2008; Day et al. 1991). The review "confirms that incidental acquisition of vocabulary is more powerful than intentional learning" across multiple cited studies.

"A wealth of research have supported the claim that vocabulary can be acquired subconsciously while receiving comprehensible input"

Discussion¶

Learner Variables¶

• Oral Language — outcome: instruction changes it
• Vocabulary — outcome: instruction changes it

Related Claims¶

• Pairing Contextual Encounters With Explicit Instruction Produces Stronger Vocabulary Outcomes Than Either Alone — the general claim this finding bears on, with the studies behind it
• Listening to vocabulary lessons while physically active improves End-of-Unit exam performance over traditional intentional learning alone — related
• Incidental vocabulary exposure produces reliable learning, but learners pick up only a small share of the unknown words they meet — a broader claim this one bears on
• ESL students using a spaced L2 vocabulary acquisition strategy with monthly incidental listening outperformed comparison students on the End-of-Experiment test — related
• Incidentally acquired vocabulary is retained over time while intentionally learned (focus-on-form) words are rapidly forgotten — a narrower finding that bears on this claim
• Combining intentional and incidental vocabulary learning produces greater gains and better retention than either mode alone — reports the opposite
• The SVAS group outperformed the comparison group across oral comprehension and vocabulary rubrics, with the largest gaps in answering questions and translating from Ukrainian — related
• Reading and listening yield similar proportions of incidental vocabulary learning, with reading ahead only on some immediate posttests — related
• Treatment effect interacts with exam sub-section, with oral comprehension showing the largest LWPA advantage — related
• Generation effects are larger in incidental than intentional learning studies, though the direct intentional-vs-incidental contrast was not significant — related
• Intentional vocabulary learning yields higher, faster gains and better retention than incidental learning through reading — reports the opposite
• Amount of listening time while active was not significantly related to End-of-Unit exam performance — a narrower finding that bears on this claim
