Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? Two variables appear to influence the success of FFI in developing implicit knowledge: the choice of the target structure and the extent of the instruction. → Rod Ellis 2002
Evidence¶
Rod Ellis 2002¶
Rod Ellis. (2002). Does Form-Focused Instruction Affect the Acquisition of Implicit Knowledge? A Review of the Research. Studies in Second Language Acquisition, Volume 24, Issue 2. https://doi.org/10.1017/S0272263102002073
q2 · i? · review · r?
The review's cross-study synthesis identifies moderator variables of FFI success, stating that "the choice of the target structure and the extent of the instruction" appear to influence outcomes. This is the review's interpretive identification of moderators, not a pooled statistical test.
"points to two variables that appear to influence its success—the choice of the target structure and the extent of the instruction"
Discussion¶
Related Claims¶
- Explicit L2 grammar instruction leads to larger learning effects than implicit instruction, as reported in the reviewed synthesis literature — the general claim this finding bears on, with the studies behind it
- FFI involving extensive instruction directed at simple structures was more likely to succeed in developing implicit knowledge — a narrower finding that bears on this claim
- Form-focused instruction can contribute to the acquisition of second language implicit knowledge, as shown in studies measuring learners' free production — a broader claim this one bears on
- Limited instruction directed at complex structures also proved effective, provided the target structures are readily available in noninstructional input — a narrower finding that bears on this claim
- Noninstructional cognitive-behavioral and behavioral methods programs are also effective — related
