  5. Highlights • Visual display of interface creates a platform which allows students to interact with facial features, for fun and stimulation • Builds on intelligence by encouraging students to use a different means to an end; rather than calculating standard deviation-they use visual properties to determine answer • Provides positive feedback and well as helpful suggestions for improving incorrect answer Standard Deviation PSLC 6.07
