Anatomy and physiology courses are a foundation for numerous degrees, but experience some of the highest failure rates of all undergraduate health science programs (Higgins-Opitz & Tufts, 2014). While interventions have been developed in an attempt to remediate this concerning phenomenon, there is a paucity of evidence to determine the reason…

The Zimbabwe Secondary School Science Project (ZIM-SCI) developed student study guides, corresponding teaching guides, and science kits for a low-cost science course which could be taught during the first 2 years of secondary school without the aid of qualified teachers and conventional laboratories. This ZIM-SCI study guide presents activities…
