The x-axis shows hours of the day(in teachers' local time zones), while the y-axis shows days of the week. Each square represents a specific day-hour combination, with colorintensity indicating how much time teachers in said engagement level spend using the platform during that time slot. Usage time is measuredusing "runs"—continuous periods when a teacher interacts with a single platform feature before switching to another feature or ending theirsession. To ensure accuracy, we cap unusually long runs at 2 standard deviations above the average duration for each feature type, and excludeteachers' final runs of each day (since we cannot observe when they actually stop using the platform), unless it was their only activity that day.The slider at the bottom allows you to explore how usage patterns evolve as teachers spend more days actively using the platform.
