Reading Simplified

I wanted to review the Reading Simplified program. While there are no studies directly studying the program, the author Dr. Marnie Ginsberg informed me that the program was based on a previous program she created called Targeted Reading Intervention (TRI) which includes “the same instructional framework, word work activities, and diagnostic thinking”. She was also kind enough to provide me with a bibliography of studies conducted on TRI, which I then used to conduct my own meta-analysis.  For studies, which an effect size had already been calculated, I accepted the authors original calculations. When no effect size was available, I calculated my own using Cohen's d. To the best of my knowledge, there have been 8 studies conducted on TRI, half of which were co-authored by Dr. Ginsberg. Overall, I would say that it is fair to call the quality of the research high, as all of these studies have sample sizes above 100, a few have sample sizes in the thousands and over half of these studies were randomnized control trials. Moreover, all of these studies were on grades kindergarten to one, which is when phonics interventions have been shown to have the highest impact. 



Meta-Analysis Discussion:

All of the outcomes from this meta-analysis were statistically significant, as were the mean effect sizes for each study. However, the mean effect size was in the moderate range. This suggests that the program has a consistent and moderately positive effect. The mean ES, corrected for outlier studies was .45, which is slightly, higher than the NRP and my findings for phonics overall, but not by a statistically significant margin. However, lower quality studies tend to produce higher results, whereas all of the studies in this meta-analysis were of very high quality.  


Principles of Reading Simplified:

From what I can gather from the curriculum documents sent to me by Dr. Ginsberg, the program prioritized the direct instruction of segmented phonics, small groups, handwriting, and irregular words vocabulary. Interestingly, Reading Simplified is one of the only well studied linguistic phonics programs and therefore might be the best example of research we have on the topic. Most of these ideas are evidence-based within the literature, with the exception of irregular vocabulary instruction. However, from an anecdotal perspective, I am sure it is necessary for a phonics program. 

One thing that surprised me about this program was the focus on blended phonics, right from the start of Kindergarten,  which according to the NRP study, has an ES of .67, compared to an ES of .87 for segmented phonics. I really liked that this program stresses the importance of small groups instruction for phonics, as the NRP meta-analysis showed an ES for small group phonics of 1.38. 


Final Grade: A+


Most of the program principles are well evidenced, within the meta-analysis literature. A mean effect size above .40 was found for studies with control groups, on standardized tests.
