Experimental Evaluations Assessing Impact
Few experimental evaluations have been conducted on the impact of ICTs on student outcomes in the developing world.ii Advocates frequently propose ICTs in the classroom, but often do so with little rigorous evidence to support their claims (F. Barrera, personal communication, August 25, 2008). Additionally, very few randomized controlled trials (RCTs) have been conducted and as a result, important questions remain unanswered, such as whether differential effects across subgroups exist, whether certain ICT interventions are more successful than others, and what factors mitigate and enhance the success of ICT interventions.
