Limited rigorous evidence is available from sub-Saharan Africa regarding whether children who learn to read in their mother tongue will have higher learning outcomes in other subjects. A randomised controlled trial of mother-tongue literacy instruction, the Primary Math and Reading (PRIMR) Initiative, was implemented in Kenya from 2013 to 2014. We compared the impacts of the PRIMR mother-tongue treatment group in two languages with those of another group that did not use mother tongue, but utilised the same instructional components. Results showed that assignment to the mother-tongue group had no additional benefits for English or Kiswahili learning outcomes beyond the non-mother-tongue group, and that the mother-tongue group had somewhat lower mathematics outcomes. Classroom observational analysis showed that assignment to the mother-tongue group had only small impacts on the usage of mother tongue in other subjects. Advocates for mother-tongue programmes must consider such results alongside local implementation resistance in programme design.

Article published in the International Journal of Education and Development, Volume 50. From Journal abstract: "Initial access to school is nearly universal in Kenya, but many children who enroll drop out before completing primary school. In this mixed-methods study, we use quantitative data from a randomized control trial involving 2666 upper primary-grade students, as well as qualitative data from interviews with 41 schoolchildren, dropouts, and parents, to examine dropout. Poorer baseline performance on literacy and numeracy assessments predicted a higher risk of dropout. Interviews revealed that children are the primary decision-makers rather than parents. Together, these findings suggest that school quality interventions may be an effective means of reducing primary school dropout in this region."

Article published in Journal of Research on Educational Effectiveness. Published abstract: We evaluated a program to improve literacy instruction on the Kenyan coast using training workshops, semiscripted lesson plans, and weekly text-message support for teachers to understand its impact on students’ literacy outcomes and on the classroom practices leading to those outcomes. The evaluation ran from the beginning of Grade 1 to the end of Grade 2 in 51 government primary schools chosen at random, with 50 schools acting as controls. The intervention had an impact on classroom practices with effect sizes from 0.57 to 1.15. There was more instruction with written text and more focus on letters and sounds. There was a positive impact on three of four primary measures of children’s literacy after two years, with effect sizes up to 0.64, and school dropout reduced from 5.3% to 2.1%. This approach to literacy instruction is sustainable, and affordable and a similar approach has subsequently been adopted nationally in Kenya.

Article published in Comparative Education Review. Published abstract: 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 program teaching literacy in English and Kiswahili and the PRIMR-MT program, which taught literacy in English, Kiswahili, and mother tongue—in two different language environments. Implementation of the MT program faced challenges because many educators were not speakers of the languages, some communities resisted mother tongue instruction, and some areas were more language heterogeneous. Effect sizes on MT literacy averaged between 0.3 and 0.6 standard deviations. The base PRIMR program also increased MT learning outcomes in some measures but had smaller effects than the PRIMR-MT program in oral reading fluency and comprehension.

Article published in the International Journal of Educational Development, Volume 49, July 2016, Pages 204–214. Published abstract: Education policymakers are investing in information and communications technology (ICT) without a research base on how ICT improves outcomes. There is limited research on the effects of different types of ICT investments on outcomes. The Kenya Primary Math and Reading (PRIMR) study implemented a randomized controlled trial comparing the effects and cost of three interventions – e-readers for students, tablets for teachers, and the base PRIMR program with tablets for instructional supervisors. The results show that the ICT investments do not improve literacy outcomes significantly more than the base non-ICT instructional program. Our findings show that cost considerations should be paramount in selecting ICT investments in the education sector.
