Subclaims¶

q3 i? The study found no advantage for implicit learners over other condition groups on complex (hard) rules, disconfirming Reber's and Krashen's first claim. → Peter Robinson 1996

Evidence¶

Peter Robinson 1996¶

Peter Robinson. (1996). Learning Simple and Complex Second Language Rules Under Implicit, Incidental, Rule-Search, and Instructed Conditions. Studies in Second Language Acquisition, Volume 18, Issue 1, pp. 27-67. https://doi.org/10.1017/S0272263100014674

q3 · i? · causal · r?

In the randomized experiment, the null contrast between implicit learners and other learners on complex rules is reported as a failure to support the first claim; no effect size or test statistic is printed in the available text.

"Results do not support the first of Reber's and Krashen's claims but do support the second. Implicit learners do not outperform other learners on complex rules, but instructed learners outperform all others in learning simple rules."

Discussion¶

Related Claims¶

• Explicit L2 grammar instruction leads to larger learning effects than implicit instruction, as reported in the reviewed synthesis literature — reports the opposite
• Explicit grammar teaching outperforms implicit teaching; one review found the advantage only for complex rules, but a meta-analysis found it for simple rules too — reports the opposite
• High-explicitness rule-oriented instruction outperforms implicit instruction or no instruction — reports the opposite
• Review synthesis: explicit teaching matters, but its advantage over other approaches varies by context and structure — related
• No differential effect of explicit instruction depending on the variable complexity — related
