q3 i0 Linguistic comprehension intervention programs produce small positive immediate effects on generalized measures of linguistic comprehension skills (g = 0.16). → Rogde K 2019

Evidence¶

Rogde K 2019¶

Rogde K, Hagen ÅM, Melby‐Lervåg M, Lervåg A. (2019). The effect of linguistic comprehension instruction on generalized language and reading comprehension skills: A systematic review. Campbell Systematic Reviews. https://doi.org/10.1002/cl2.1059

q3 · i0 · g = 0.16, below the d 0.2 cut-off; the review calls it small · quant-synthesis · r2

Systematic review and meta-analysis of 43 control-group studies (RCTs and QEs) in educational settings, 1992–2017; quasi-experiments needed pre- and posttests, while RCTs with a posttest-only design were also eligible. The review reports a "small summary (mean) effect size (g = 0.16)" for the immediate effect on generalized linguistic comprehension, and calls the effect "small in studies of both the overall immediate and follow‐up effects"; the immediate effect on generalized reading comprehension was negligible (g = 0.05).

"The effect of linguistic comprehension instruction on generalized outcomes of linguistic comprehension skills is small in studies of both the overall immediate and follow‐up effects."

Discussion¶

Learner Variables¶

• Oral Language — outcome: instruction changes it

Related Claims¶

• Linguistic comprehension instruction shows no clear immediate effect on generalized reading comprehension outcomes — related
• Effects of linguistic comprehension instruction differ by outcome domain: small for vocabulary and grammar, moderate for narrative and listening comprehension — a narrower finding that bears on this claim
