Typos
I added an appendix (referred to in the \paragraph “What is CT”) to give a hint to the reader why we can claim that CT is “a skill for everyone.”

I added to the sentence describing what we did in Teacher Training Session “3. Algorithms”.

I added my name to the author list.

I fixed a typo or two.
