MARCES conference
Chris Correa and I just gave our talk to this conference, which went pretty well.
Now we’re listening to a really interesting talk by Dylan Wiliam (not spelling of his surname—he’s Welsh) at ETS, that’s really interesting. A few things I’m learning
- there’s a belief in England (going back to something called the Cockcroft report of 1982 or so) that there’s a seven year gap in performance of students in the same classroom.
- he has an interesting measure of “sensitivity to instruction” for tasks based on measures of effects of instruction compared to individual differences among students of the same age/class. In general, variation within classes is much larger than differences between grades.
