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? Input-based instruction was more effective at beginner (difference .05) and intermediate (difference .31) levels, and both FFI types had much higher effect sizes for intermediate learners. → Schenck 2024
Evidence¶
Schenck 2024¶
Schenck, A. (2024). Learning How to Use Input-Based and Output-Based Form-Focused Instruction: A Meta-Analytic Comparison of Persian EFL Learners. Journal of Second Language Acquisition and Teaching, 30. https://eric.ed.gov/?id=EJ1457419
q2 · i? · quant-synthesis · r1
Meta-analytic comparison by proficiency designation (Table 3: beginner input mean .9881, output .9355; intermediate input 3.6230, output 3.3086). Only 28 of 41 treatment groups had proficiency designations; none were advanced.
"Input-based instruction was more effective at both the beginner and intermediate levels. At the beginner level, the difference was .05, which is a nominal difference in effect."
Discussion¶
Related Claims¶
- Input-based FFI is more effective than output-based FFI for inter-phrasal grammatical features, with a medium-sized difference — related
- Grammatical complexity and L2 proficiency interact: complex features benefit more from input at low proficiency, while simple features benefit more from output at high proficiency — related
- Input-based FFI is only slightly more effective than output-based FFI for intra-phrasal grammatical features in Persian EFL learners — related
- Output-based FFI was more effective than input-based FFI for complex clausal grammatical features, a difference the article characterizes as a large effect — reports the opposite
- L1 transfer may moderate FFI effectiveness: features similar to Persian benefit more from input, while disparate features benefit more from output — related
- Proficiency level and input delivery method (FFI vs. no-FFI) interact significantly in their effect on grammatical knowledge — related
