Drawing on the latest findings from neuroscience and cognitive psychology, Michelle Miller explores how attention, memory, and higher thought processes such as critical thinking and analytical reasoning can be enhanced through technology-aided approaches. The techniques she describes promote retention of course material through frequent low‐stakes testing and practice, and help prevent counterproductive cramming by encouraging better spacing of study. Online activities also help students become more adept with cognitive aids, such as analogies, that allow them to apply learning across situations and disciplines. Miller guides instructors through the process of creating a syllabus for a cognitively optimized, fully online course. She presents innovative ideas for how to use multimedia effectively, how to take advantage of learners’ existing knowledge, and how to motivate students to do their best work and complete the course.
