Pen(cil) and Paper.
I just finished “Smarter Faster Better” by Charles Duhigg and one of the points it made was people get into “Information Blindness”. They can’t see things because there is too much information. If one has too many choices one gives up and doesn’t make a choice. If that happens one needs to engage the data. Ask questions of it to get to the information one wants. It gave the example of choosing a wine. Red or white? What year? Cheap or expensive? Soon a long list can be manageable.
When it came to students, hand written notes were better than typed notes on a computer for better test results. Teachers at a low performing school were able to change the school by making cards for each student and seeing what the patterns were. They had the data on computers but they weren’t engaging it.
My opinion is paper and pen helps us because it is more like a picture. Our minds love pictures. And when we create pictures our minds connect with the information.
