ABC, 123: The Impact of a Mobile Phone Literacy Program on Educational Outcomes

CGD non-resident fellow Jenny Aker and co-authors report on the results from a randomized evaluation of a mobile phone education program (Project ABC) in Niger, in which adult students learned how to use mobile phones as part of a literacy and numeracy class. Overall, students demonstrated substantial improvements in literacy and numeracy test scores. There is also evidence of persistent impacts: six months after the end of the first year of classes, students in the program retained what they had learned better than others. The effects do not appear to be driven by differences in teacher quality or in teacher and student attendance. The results suggest that simple and relatively cheap information and communication technology can serve as an effective and sustainable learning tool for rural populations.

Call Me Educated: Evidence from a Mobile Monitoring Experiment in Niger

In rural areas of developing countries, education programs are often implemented through community teachers. While teachers are a crucial part of the education production function, observing their effort remains a challenge for the public sector. This paper tests whether a simple monitoring system, implemented via the mobile phone, can improve student learning as part of an adult education program. Using a randomized control trial in 160 villages in Niger, we randomly assigned villages to a mobile phone monitoring component, whereby teachers, students and the village chief were called on a weekly basis. There was no incentive component to the program. The monitoring intervention dramatically affected student performance: During the first year of the program, reading and math test scores were .15-.30 s.d. higher in monitoring villages than in nonmonitoring villages, with relatively stronger effects in the region where monitoring was weakest and for teachers for whom the outside option was lowest. We provide more speculative evidence on the mechanisms behind these effects, namely, teacher and student effort and motivation.

Can ABC Lead to Sustained 123? The Medium-Term Effects of a Technology-Enhanced Adult Education Program

Can information technology preserve the short-term learning gains associated with adult education programs? This study estimates the medium-term impacts of a mobile phone module (Project ABC) that was added to a standard adult education curriculum and for which there were significant short-term impacts on educational outcomes. Two years after the end of the program, students in ABC villages had reading scores that were significantly higher than those in standard adult education classes, and women and younger students were better able to decode numbers. This can be partially attributed to more active mobile phone usage in ABC villages. Households in ABC villages also were more likely to own certain durable assets, had higher levels of food security, and were more likely to save. Overall, these results suggest that short-term learning gains associated with technology can persist, especially if students have the opportunity to practice using that technology after the end of classes.

Learning Without Teachers? A Randomized Experiment of a Mobile Phone-Based Adult Education Program in Los Angeles

Over 755 million adults worldwide are unable to read and write in any language. Yet the widespread introduction of information and communication technology offers new opportunities to provide standardized distance education to underserved illiterate populations in both developed and developing countries. Using data from a randomized experiment of an innovative mobile phone-based adult education program (Cell-Ed) in Los Angeles, we find that the Cell-Ed program significantly increased students’ basic and broad reading scores, equivalent to a 2-4 year increase in reading levels over a four-month period. The program also increased participants’ self-esteem by 7 percent as compared with the comparison group. These results are robust to correcting for non-random attrition using a variety of non-parametric methods, including using the phase-in design to tighten the Lee bounds. Our results suggest that there is great scope for using information technology as a means of improving educational skills for illiterate adults.
