Russ Walsh writes here about the difference between “belief” and “knowledge.”

He writes:

I imagine that most of those who read this blog accept climate change and the human impact on climate change as settled science. We’ve seen the evidence; we’ve heard from the experts and we have reached an informed conclusion. This is a good thing and one that most Americans not in the White House or in denial for economic and political reasons also accept. It is not a matter of believing or disbelieving climate science; it is a matter of rigorous academic inquiry.

Now I would ask all teachers and teacher leaders to apply the same academic rigor to instructional practice. That is we must make our instructional decisions on what we know works – based on research.

Unfortunately as I have talked to teachers over the years about instructional practice, I have heard a lot of faith-based language.

“I don’t believe in homework.”

“I believe in phonics.”

“I don’t believe in teaching to the test.”

“I believe in independent reading.”

“I believe in using round robin and popcorn reading.”

For about 2,000 years doctors “believed” that blood-letting was an effective treatment for a wide variety of ailments. Today, I would bet if you encountered a doctor who recommended blood-letting for your flu symptoms, you would run, not walk, out the office door screaming. Science, and mounting numbers of dead patients, caught up with blood-letting. So, as professionals, we need to hold ourselves to the same standards. We need to follow the science and stop talking about our beliefs and start talking about the scientific research behind our instructional decision making.

What do you do when the research is inconclusive or when research findings conflict?

Russ has some advice for you.
