In fact, I wonder why Kane compared his attempts to quantify instructional effectiveness to two issues that have little or nothing to do with that issue. Seniority is the teacher’s First Amendment in that it protects educators from the whims of their bosses, not to mention politicized fads. There are many simpler and safer ways to
