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.

q4 i2 Across 216 effect sizes from 105 independent samples, L2 anxiety correlates negatively with language achievement at a mean of r = −.36. → Yasser Teimouri 2019

Evidence

Yasser Teimouri 2019

Yasser Teimouri, Julia Goetze, and Luke Plonsky. (2019). SECOND LANGUAGE ANXIETY AND ACHIEVEMENT: A META-ANALYSIS. Studies in Second Language Acquisition, Volume 41, Issue 2. https://doi.org/10.1017/S0272263118000311

q4 · i2 · quant-synthesis · r2

Meta-analysis of 97 reports contributing 105 independent samples (N = 19,933) from 23 countries; the aggregate of 216 correlations yielded "a mean of r = −.36 for the relationship between L2 anxiety and language achievement."

"In the aggregate, the 216 effect sizes (i.e., correlations) reported in the primary studies yielded a mean of r = −.36 for the relationship between L2 anxiety and language achievement."

Studies bearing on this claim

Do learners who are more anxious about a foreign language achieve less in it, and for which kinds of anxiety, outcome and learner? This table gathers the studies behind this claim and the 7 narrower claims that bear on it: 4 distinct studies (2 associational, 1 quant-synthesis, 1 qualitative), q1–q4, 2 of 4 with an effect size coded. One row per study, codes as each entry records them; no effect is averaged and no verdict is drawn. Built by scripts/synthesize_claim.py from eval/synthesis/; a row that looks wrong is fixed on the claim it comes from.
