Verified content
- [abstract] 17 studies met inclusion standards.
- [abstract] Of 13 elementary studies of Spanish-dominant students, 9 favoured bilingual approaches on English reading and 4 found no difference: median effect size +0.45, sample-size-weighted +0.33 (p < .05).
- [abstract] The authors call the number of high-quality studies small and ask for longitudinal randomised designs.
Limits
- [assessment] Abstract only. Mostly US Spanish-speaking pupils; few high-quality studies. The randomised trial the authors called for is Slavin et al. 2011 (BILIN-004), which found no lasting difference.
Why it is in the library
The standard older review on C34's question, by the same group that later ran the randomised trial; pairs naturally with BILIN-004.
