SIPPS is a Structured Literacy program that describes itself as “The program's systematic scope and sequence provides a structured-literacy approach to instruction through explicit routines focused on phonological awareness, spelling-sounds, and sight words.” The program includes the explicit instruction of phonological awareness, phonics, fluency (via repeated reading), and comprehension. The program also makes use of the principles of mastery teaching, scaffolding, and differentiation.
There exists no peer reviewed meta-analysis of SIPPS. I searched for SIPPS studies on Google, their company website, Education Source, and Sage Pub. I as able to find two studies done with sufficient data to analyze with a meta-analytic lens, meaning they had control groups and enough statistical data to find effect sizes. For these two studies the authors had calculated their own effect sizes with Cohen's d. The first study was conducted by the SIPPS company in 2002, in Nappe California. This study looked at 1 year of SIPPS instruction for 547 grade 1-3 students. The second study was a doctoral thesis by John Thomas, conducted in 2004. His study looked at 1 year of SIPPS instruction in a California School, and compared it to a school in the same district that did not use SIPPS. Both studies were quasi-experimental, meaning they used control groups, but were not randomized. Both studies only looked at decoding outcomes. Both studies were on grades 1-3 students.
SIPPS has all of the most important principles of any evidence-based literacy program. However, of the two studies we have on it, the outcomes are very low, for reasons that I honestly, cannot discern. There might just not be enough research yet on SIPPS or the program might have aspects that are challenging to execute on.
Final Grade: B
-The program principles are evidence-based, but research studies showed a mean effect size below .30
Qualitative Grade: 8/10
The program contains the following essential types of instruction: individualized, direct, scaffolded, phonemic awareness, phonics, fluency and comprehension.
