Study: Improving Teachers' Math Knowledge Doesn't Boost Student Scores

CAT Tracks Editor's Note:

The group that participated took an intensive 80-hour workshop in the summer of 2013 that "focused on deepening teachers' knowledge of grades K-8 mathematics." Teachers also received 13 hours of professional development during the 2013-14 school year, including meetings during which they analyzed student work and one-on-one coaching sessions.

And their students "actually scored 2 percentile points lower than the control teachers' students on both the state math assessment and another test."

Another useless study?

Not at all:

• Those who do studies have reason to conduct another study. Keeps those grants and paychecks coming!

• Education "reformers" and politicians have justification (not that they ever needed it) to expand their criticism to all teachers. The study clearly shows (from their biased perspective) that it's not just "bad teachers" who are harming students, it's all of them. Bring on technology, expand online learning, monitored by I, Robot.

As is oft lamented...

...damned if you do, damned if you don't.
