q2 i? Reviews identified explicit instruction in individual words, rich and in-depth vocabulary instruction, visuals/realia/gesture, careful word and text selection, L1 use, and word-learning strategies as effective for improving MLs' English vocabulary. → Kittle 2024

Evidence¶

Kittle 2024¶

Kittle, J. M., Amendum, S. J., & Budde, C. M. (2024). What Does Research Say About the Science of Reading for K-5 Multilingual Learners? A Systematic Review of Systematic Reviews. Educational Psychology Review. https://doi.org/10.1007/s10648-024-09942-6

q2 · i? · quant-synthesis · r2

Synthesis of instructional-practice findings across multiple systematic reviews (RQ2). The review reports explicit word-meaning instruction increased MLs' English vocabulary, citing Carlo et al. (2004) on target-word, depth-of-meaning, and multiple-meaning gains; systematic phonologically based interventions also had significant effects on English vocabulary. No pooled effect size is printed.

"Explicit instruction of English word meanings increased MLs’ English vocabulary. A single study within the reviews (Carlo et al., 2004) found direct instruction in key vocabulary words improved MLs’ English knowledge of target words, depth of meaning vocabulary knowledge, and understanding of multiple word meanings"
