Students and Teachers Use An Online AP CS Principles EBook Differently: Teacher Behavior Consistent with Expert Learners

Online education is an important tool for supporting the growing number of teachers and students in computer science. We created two eBooks containing interactive content for Advanced Placement Computer Science Principles, one targeted at teachers and one at students. By comparing the eBook usage patterns of these populations, including activity usage counts, transitions between activities, and pathways through the eBook, we develop a characterization of how student use of the eBook differs from teacher use. We offer design recommendations for how eBooks might be developed to target each of our populations. We ground our recommendations in a theory of teachers as expert learners who possess a greater ability to regulate their own learning process.
