This study identifies opportunities to train CHWs more cost effectively through technology-enabled multimedia content that leverages visuals, videos, or audio. It also highlights the potential to create open, easily sharable digital content that could act as a crucial ingredient for new approaches to training and learning in the future. The report walks through existing approaches to CHW training and content development, current uses of mobile technology, and emerging evidence on effective approaches to training, highlighting advantages of digital and multimedia content for scale.
In addition to their effectiveness and appropriateness, according to the report, the use of blended approaches to training would require less time and personnel than conventional approaches, and are more cost-efficient to scale: the projected cost of content and instruction necessary to meet the demand of one million trained CHWs in sub-Saharan Africa would be approximately 75% less using a blended approach than the cost to scale using traditional methods. The report also found that an estimated 80% of training content is transferable between countries, suggesting that customising training content to local contexts - including adjustments for language, culture, and literacy - may not be as big a barrier as perceived.
