What is missing in edtech is a concept of progress and partial correctness and guess work. The primary input in edtech is multiple choice. This is selected so a person does not need to evaluate the answer making it cheaper. But leads to kids guessing. Starting a blank line to write a response is what really kicks the brain in. There is no easy way out.

We could replicate the same blank page and grayscale human response to questions. But then we have not made a cheap factory that reduces costs. Its the typical fast, good, cheap conundrum. Everyone keeps picking cheap and getting mad when it does not work.

Or, almost as bad, kids learning to approximate the answer. I aced too many multiple-choice physics exams in my GCSEs because the multiple choice was A) 1,000,000 B) 1,000 C) 100 D) 10. Without knowing the formula I was able to eyeball which numbers looked obviously wrong and just select the closest.

At least from what I remember in A-level physics, a lot of the multi-choice answers usually had 2 sets of answers, both of which were ambiguous and could be the correct answer. A few questions even had answers where they were all the same answer, just with the digits either transposed or the decimal point being different. Stuff like

A) 1.2e10 B) 1.2e9 C) 2.1e10 D) 2.1e11
