We create 2.5 exabytes per day

90% of the data in the world today was created in the last two years

giga = 10⁹ ≈ 2³⁰ tera = 10¹² ≈ 2⁴⁰ peta = 10¹⁵ ≈ 2⁵⁰ exa* = 10¹⁸ ≈ 2⁶⁰ zetta = 10²¹ ≈ 2⁷⁰ yotta = 10²⁴ ≈ 2⁸⁰

In most education research, teaching methods are tested in small groups, comparing results in different classrooms. Conclusions can be uncertain and are often not available until the end of school semester.

But in an online class of 20,000 students, whose every mouse click is tracked in real time, the research can be more definitive and immediate.

If 5,000 people had the same wrong answer, it’s obvious a concept is not getting through, and you have a clear path that shows where students went wrong.
