This background paper reviews the literature-based evidence, a set of household surveys and a series of practice-based interventions in relation to educational technologies (EdTech) and gender in the context of Low-and Middle-Income Countries (LMICs), with focused research in Kenya, Sierra Leone and Tanzania.We illustrate that the main categories of factors to consider to design EdTech interventions to support girls' education are the access, use and content of EdTech. We introduce a framework that summarises the findings of this background paper and that can be used to consider these evidence-based factors throughout EdTech interventions.To design inclusive EdTech interventions to support girls' education these factors need to be explored through gender, political economy and intersectional lenses.The evidence for EdTech to support girls' education tends to point to barriers and enablers that need to be considered to design inclusive and egalitarian EdTech interventions (these are summarised in the framework introduced in Page 44). For example, in relation to the access of EdTech, we found that a barrier to inclusive and equitable quality education for all was that girls tended to be less likely than boys to own or be able to access mobile devices in LMICs. We also found that an enabler to improve EdTech access was to use EdTech for nudging and changing inequitable beliefs, although this needs to be carefully considered within context.There are barriers that need to be considered for all EdTech interventions aiming at supporting girls' education in LMICs. These are barriers related to reaching the most marginalised girls with EdTech, for example by ignoring political economy factors or the need for additional support for marginalised children (e.g financial, health or social support); neglecting to collect gender data throughout EdTech intervention; and disregarding the role of contextual inequalities, intersectionality and gender norms in supporting egalitarian learning through EdTech. While these factors are challenges for all educational interventions to some extent, there is a particular risk that without careful consideration, EdTech interventions could exacerbate existing 'digital divides' and increase inequity.
