Working Memory and Exploration in Training the Knowledge and Skills Required by Digital Systems.

摘要

Variations in computer-based training (CBT) procedures were compared in training the skills and knowledge required of a prototype map interface for the Land Warrior system. Soldiers from four Infantry courses participated, representing the chain of command within an Infantry platoon, from platoon leader to rifleman. Soldiers were first trained on codes that uniquely identified individuals and units on the map. Then soldiers learned how to use map functions such as pan, zoom, determine range, and find individuals and units. Lessons that contained a large volume of information before soldiers could apply that information and commit it to memory resulted in low scores on both the code and map exercises. Breaking: up the content into smaller chunks of information tended to be more effective. Although soldiers who learned the map on their own via an exploratory condition had the lowest map performance, exploratory learning may have potential as these soldiers spent relatively little time 'exploring'. The results demonstrate the importance of adapting to individual differences in the learning rate of soldiers. They also provide insights regarding how to design effective and efficient CBT for digital systems.
