Somehow, someway, we are already on episode 9 of year 2 of the Progressively Incorrect podcast!
These days I have the complete satisfaction of speaking with the outstanding Nate Joseph, the creator of the Scientific Principles of Instructing (check out this site for all his books) Nate is a admirer of secondary meta-investigation, a methodology popularized by Dr. John Hattie in his e book Visible Mastering. For many educators, Hattie’s investigate has turn into the initial and most direct entry position into the evidence-centered education and learning motion, which I absolutely support. Nevertheless, in the latest several years, Hattie’s techniques have arrive underneath a whole lot of fire and criticism. For illustration, pay attention to this quote from the late Robert Slavin’s weblog:
A meta-investigation can’t be any much better than the scientific studies that go into it. Hattie’s claims are deeply misleading for the reason that they are based mostly on meta-analyses that on their own accepted experiments of all levels of high-quality. Evidence issues in instruction, now extra than ever. However Hattie and other people who uncritically accept all reports, superior and lousy, are undermining the worth of evidence. This demands to quit if we are to make solid progress in academic exercise and policy.
No issue how you slice it, it appears problematic to mush a bunch of crummy research together to produce an result sizing, and say that this is definitive evidence that a little something is effective better than one thing else. In our discussion, Nate addresses several of the criticisms of Hattie’s work, while providing techniques that his tactic to secondary meta-evaluation improves upon, and removes many of the flaws, of some of Hattie’s before get the job done. The very best element of our discussion, nonetheless, is how Nate is in a position to leverage his experience as a instructor to notify the tale powering the proof that constitutes the science of reading through and math.
So sit back, unwind, and take pleasure in Time 2 Episode 9 of the Progressively Incorrect Podcast, featuring Nate Joseph.
