This morning, reviewing notes I’ve stashed away (and realizing how important it is that I wrote things down), I came across this:
In one day, I visited three different 8th grade classrooms, and in each of those classes they used their textbooks:
In the first, they used them to prop up inclined planes.
In another, they used them as masses that were being dragged by a force scale.
In the third, they used them on the input end of a lever arm to lift up a student.
The books were never opened.
