The above image shows two very different approaches to education. Of course, the one on the left is more idealistic, and centered less on matters like standardized testing. The one on the right is what I’ve seen much more of in the public-school system that I work as a guest teacher.
This “Factory Model” usually fuels the day-to-day operations, and the students work on the rewards and punishment [actually, bribery] system, with competition being the #1 motivator.
I’ve had only a sprinkling of “Mastery Model” assignments over the years, and the time flew by, with students being willing, independent learners.
