The Education Lab conducted a study of a high-dosage math tutoring model that combines technology and tutors to improve high school math outcomes at a lower cost to schools.

Challenge

High-dosage tutoring has proven to be effective at improving high school student math outcomes. However, the costs associated with high-dosage tutoring are a barrier to school districts that need help to fund the traditional model at scale. Infusing technology into high-dosage tutoring through a computer-assisted learning (CAL) platform offers one way to reduce costs.

Opportunity

The tutoring provider Saga Education incorporated technology into their high-dosage tutoring model, adapting it so that students alternate between working on a CAL platform and directly with an in-person tutor every other day. The Education Lab conducted a randomized controlled trial (RCT) to evaluate this new model; results are expected to be released in late 2023

Project overview

Education researchers have long known that small-group tutoring generates some of the “best learning conditions we can devise,” partly because it personalizes instruction and provides opportunities for mentorship (Bloom, 1984). Prior research has demonstrated that both in-person tutors and education technology are promising methods of delivering individualized, effective instruction to meet students where they are. Past work by the Education Lab has demonstrated that Saga Education’s high-dosage, individualized, during-the-school-day math tutoring model can generate large and significant gains in academic outcomes—up to two and a half years of additional learning—in a short period, even among students who are behind grade level. However, one significant barrier to scaling up this promising intervention is cost: the traditional high-dosage tutoring model is too expensive for most schools to serve as many students as would benefit. Increasing access to high-dosage tutoring requires finding a method to serve more students without losing effectiveness. 

Saga Education, in partnership with Chicago Public Schools (CPS) and the New York City Department of Education, piloted a new blended-learning version of their traditional tutoring model during the 2018-19 and 2019-20 school years with the aim of reducing program costs while maintaining the effectiveness found in the previous evaluations of Saga’s tutoring model. Under this new “Saga technology” model, participating students received Saga programming every day, but unlike the previous version, students alternated between a day of working with their in-person tutor and a day of individually engaging with an education technology platform. 

The University of Chicago Education Lab conducted a two-year randomized controlled trial – the gold standard in research – of the model during the 2018-19 and 2019-20 school years. The study involved over 3,900 ninth-grade students across seven Chicago and New York City public high schools. Results are expected to be released in late 2023.
