Sal Khan: Let's teach for mastery -- not test scores

The next morning, we'll review the homework, then another lecture, homework, lecture, homework. That will continue for about two or three weeks, and then we get a test. On that test, maybe I get a 75 percent, maybe you get a 90 percent, maybe you get a 95 percent. And even though the test identified gaps in our knowledge, I didn't know 25 percent of the material. Even the A student, what was the five percent they didn't know?
Even though we've identified the gaps, the whole class will then move on to the next subject, probably a more advanced subject that's going to build on those gaps...And that process continues, and you immediately start to realize how strange this is. I didn't know 25 percent of the more foundational thing, and now I'm being pushed to the more advanced thing. And this will continue for months, years..."
