It’s not enough to intend to do good. I mean, it just isn’t. What doctor is excused from killing a patient because that doctor cares?

The saccharine myths that I tell myself and others about my sacrifices, my work ethic, my own academic prowess, my caring, my love, do not ensure that my students learn.

There’s only one thing that comes close to doing that. Informed, multi-measured, reflective, corrective practice.
