Figure 5
: Platform Usage Times
Notes:
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 color intensity indicating how much time teachers spend using
the platform during that time slot. Usage time is measured using "runs"—continuous periods when a teacher interacts with
a single platform feature before switching to another feature or ending their session. To ensure accuracy, we cap unusually
long runs at 2 standard deviations above the average duration for each feature type, and exclude teachers' final runs of each
day (since we cannot observe when they actually stop using the platform), unless it was their only activity that day.
