He wants educators to instead teach “how do you think and how do you decompose problems”
Ahmen! I attend this same church.
My favorite professor in engineering school always gave open book tests.
In the real world of work, everyone has full access to all the available data and information.
Very few jobs involve paying someone simply to look up data in a book or on the internet. What they will pay for is someone who can analyze, understand, reason and apply data and information in unique ways needed to solve problems.
Doing this is called "engineering". And this is what this professor taught.
I had a like minded professor in university, ironically in AI. Our big tests were all 3 day take home assignments. The questions were open ended, required writing code, processing data and analyzing results.
I think the problem with this is that it requires the professor to mentally fully engage when marking assignments and many educators do not have the capacity and/or desire to do so.
I don't think the 3-day take home is the key. It's supporting educators to have the intention, agency and capacity to improvise assessment.
