Top: heat-map of daily student clickstream activity over time in a 10-week course, where the horizontal axis is in days and each row represents one student. Lighter-shaded hashes indicate fewer clicks and darker-shaded hashes indicate more clicks. Bottom: a time-series plot of the average number of clicks per day, aggregated across all students. Dates of exams and Mondays are shown in thick dashed lines and solid lines, respectively. Figure based on data and analyses in Park, Denaro, Rodriguez, Smyth, and Warschauer (2017)
