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? Experimental studies examining features similar to the Persian L1 had higher effect sizes for input-based instruction, while features highly disparate from the L1 benefited more from output-based FFI. → Schenck 2024

q2 · i? · quant-synthesis · r1
Cross-study comparison within the meta-analysis: verb tenses and the conditional (L1-similar) favored input, while passive voice, causative, relative clause, and so/such clauses favored output. The article frames this as a suggestion positive transfer may occur.
"Experimental studies that examined features similar to the L1 had higher values for input-based instruction."
Discussion¶
Related Claims¶
- Input-based FFI is more effective than output-based FFI for inter-phrasal grammatical features, with a medium-sized difference — related
- Input-based FFI is only slightly more effective than output-based FFI for intra-phrasal grammatical features in Persian EFL learners — 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
- Output-based FFI was more effective than input-based FFI for complex clausal grammatical features, a difference the article characterizes as a large effect — related
- Input-based FFI was more effective than output-based FFI at both beginner and intermediate proficiency levels, and both types showed larger effects for intermediate learners — related
- Proficiency level and input delivery method (FFI vs. no-FFI) interact significantly in their effect on grammatical knowledge — related
