Convincing Reluctant Teachers

This question was posted to Twitter today:

Question: how do you convince teachers who are ADAMANT that they teach to the rigor required by CCSS that they really don’t?

(CCSS means Common Core State Standards)

This is a great question. I think it applies to a wide range of situations. You can replace “CCSS” with the Next Generation Science Standards, the new AP Physics 1 and 2 course, or any curricula du jour. It all boils down to showing these teachers that traditional teaching methods do not lead students to a deeper understanding of the concepts.

Some folks may suggest showing the reluctant teachers sample test questions from the new assessments. I say stay far away from that. These teachers will likely look for tricks to game the assessments so students can be successful without the in-depth understanding these teachers think they are teaching.

My suggestion is to have the reluctant teachers administer a basic conceptual diagnostic test to their students. The questions are so basic, so easy, the teachers will say “Of course my students can ace this!”

And then wait for the results to come in.

In all likelihood, the students (on average) will do poorly. Amazingly poorly. Even worse than if they had simply guessed randomly.

To which the reluctant teacher responds, “What happened? They should have known all this!”

Now’s your chance. I think now they’ll be more receptive to what you have to say about how students learn math and science and why interactive engagement techniques work.


Here’s Erik Mazur (Harvard physics professor) explaining what happened when he gave his students a conceptual diagnostic test:

Extensive lists of concept inventories can be found at FLAG and NC State. Remember, many of these tests have been painstakingly developed and refined by researchers. Be sure to abide by the developers’ rules with administering the tests to students. You should not post them to the internet or discuss the answers with students.
