2. The Problem
• Increasing volumes of knowledge to retain
• Memorization tools have not fundamentally changed in 10 years
• Most of these tools center around “flashcards”
• Flashcards represent knowledge in a one-to-one relation, while integrated
knowledge requires many-to-many relations.
• Lack of detailed feedback for metacognition
• Many students lack structure

19. Case Study: “Cellular Proteins”
• Inclusion criteria
• Set with a large amount of study activity
• Reached exactly 70% mastery
• Data items recorded
• Answers, mode of study, accuracy, study sessions, mastery score, specific
content studied
• Selection:
• 17 students
• 196 facts per student to reach 70%

23. Conclusions
• When presented with multiple learning modes, medical
students show an overwhelming preference for multiple choice
questions over other modes
• Mastery scores can be used to predict accuracy
• At lower levels of subject mastery, matching is the easiest
• At moderate-to-high levels of mastery, all modes are equal
• Flashcards are not more effective than any other learning
mode, and students may benefit from having more flexibility.
24. Next steps
• Correlate study data with exam scores
• Real-time data tracking for students and educators
• Leverage data to offer personalized recommendations
• Determine optimum answer events to thoroughly master a concept
• Experiment with different strategies and modalities (e.g. spaced repetition vs.
original order vs. randomized shuffle).
• Compare mobile device vs. desktop/laptop studying
