effect size

Dan Dempsey says:

By Golly .. the insanity just will not stop .. another educational pack of lemmings is ready to follow the "Whole Language" rodents into the sea of ignorance.

Hattie Visible Learning effect sizes:

Phonics = 0.60
Whole Language = 0.06
(1/10 as effective and good for a decade of educational malpractice)

So now we are off to the decade of the twins I trust: "Problem & Project Based Learning"

Nope we don't want any of that effective stuff like Worked Examples, Direct Instruction, or Mastery learning.

Not when Problem Based Learning = 0.15

You know what?

I'm going to start talking about effect size at school board meetings.

Something new and different.
