Randomized experiments involving education interventions are typically implemented as cluster randomized trials, with schools serving as clusters. To design such a study, it is critical to understand the degree to which learning outcomes vary between versus within clusters (schools), specifically the intraclass correlation coefficient. It is also…

If children do not learn how to read in the first few years of primary school, they at greater risk of dropping out. It is therefore crucial to identify and test interventions that have the potential of making a large impact, can be implemented quickly, and are affordable to be taken to scale by the Kenyan government. This paper presents the…

Research in sub-Saharan Africa investigating the effect of mother tongue (MT) literacy instruction at medium scale is limited. A randomized controlled trial of MT literacy instruction was implemented in 2013 and 2014 as part of the Primary Math and Reading (PRIMR) Initiative in Kenya. We compare the effect of two treatment groups--the base PRIMR…

Rapid Phonics is a synthetic phonics intervention intended to improve decoding skills and reading fluency. It teaches the relationship of word sounds to their corresponding letter groups in a structured way. In this evaluation, the intervention was delivered across the transition between primary and secondary school to Year 6/7 pupils who had not…

If children do not learn how to read in the first few years of primary school, they will struggle to complete the cycle and are at greater risk of dropping out. It is therefore crucial to identify and test interventions that have the potential of making a large impact, can be implemented quickly, and are affordable to be taken to scale by the…

Switch-on Reading is an intensive 10-week literacy intervention. It is delivered on a one to one basis by staff, most commonly teaching assistants, who have been trained in the approach. The purpose of Switch-on is to achieve functional literacy for as many pupils as possible, and so to close the reading achievement gap for vulnerable children…

Children from low-income families are at risk of learning outcome difficulties, particularly in literacy. Various studies link poor literacy results with performance later in primary and secondary school, and suggest that poverty, literacy skills and weak instructional methods combine to drastically limit the educational opportunities for many…

Tutoring with Alphie is a computer-assisted programme that aims to improve the literacy skills of struggling readers. The programme combines elements of collaborative (or 'cooperative') learning, computer-assisted instruction and small group support. Participating pupils are grouped in pairs and follow a series of activities that seek to improve…

This meta-analysis summarizes research on the effects of a comprehensive, interactive web-based software (AXXX) on the development of reading competencies among kindergarteners and elementary students. Findings from seven randomized control trials and quasi-experimental studies undertaken in a variety of contexts across Canada, Australia and Kenya…
