Keep the hour the model cannot do
Here is the four-step hour, and what the studies actually showed, so you can use the tool without handing it your mind.
A student finishes the problem set in twenty minutes. The write-up is clean. The teacher is pleased. Two years later the entrance exam is eighteen to twenty-four percent worse, and nobody is surprised except the gradebook.
Can I use the model on the assignment without getting worse at the work?
