Preventative reading interventions teaching direct mapping of graphemes in texts and set-for-variability aid at-risk learners

We evaluated two experimenter-delivered, small-group word reading programs among at-risk poor readers in Grade 1 classes of regular elementary schools using a two-arm, dual-site-matched control trial intervention. At-risk poor word readers (n = 201) were allocated to either (a) Direct Mapping and Set-for-Variability (DMSfV) or (b) Current or Best-Practices small-group reading programs, typically for 10–11 hr over 10 weeks. Students were matched on baseline reading and language abilities, parent demographic measures, and observed regular classroom teaching quality. Results of hierarchical data modeling showed advantages for the DMSfV program (p < .05 for word reading and spelling at posttest and word reading and sentence comprehension at 5-month delayed posttest), with discernible valued added for the DMSfV condition across all follow-up measures. Results support the use of small-group preventative literacy intervention models that teach both direct mapping of grapheme–phoneme correspondences in text and set-for-variability

The effects of teaching complex grapheme-phoneme correspondences : Evidence from a dual site cluster trial with at-risk Grade 2 students

We evaluated the impact of teaching complex grapheme–phoneme correspondences (GPC) derived from the Simplicity Principle to at-risk poor readers in Grade 2 classrooms, using a two-arm dual site matched control trial intervention. Poor word readers (n = 149) were allocated to either a) Simplicity GPC (n= 79) or b) Letter-Name Control (n= 70) small group reading programs, and received intervention for 12–15 hours over 12 weeks. Students were matched on baseline reading, language, parent demographics, and observed regular classroom teaching quality. Results of hierarchical data modeling showed advantages for the GPC-group for word reading, pseudoword reading, and sentence comprehension at post-test moderated by pre-test phonological awareness skills. The results provide support for teaching complex GPCs derived from the Simplicity Principle as an approach to intervention for word reading, but suggest that children with low PA need additional supports
