A study published in the journal Science Education in December 2008 looked at two sets of high school science students. One set “sprinted”; the other set had teachers who slowed down, went deeper, and did not cover as much material. The results? The first group of students actually scored higher on the state tests at the end of the year. This is not surprising, as their teachers covered more of the test material. I am sure it made their parents, teachers, and administrators happy. What is more interesting, however, is that the students who learned through the slower, in-depth approach actually earned higher grades once they made it to college. This, too, is not surprising. These students were taught to think critically.The study in question, from the journal Science Education, underscores my deep concerns about our continued emphasis on standardized testing as a comprehensive measure of students' learning and our increasing emphasis on it as a measure of teachers' skills. Because the test standards focus on content knowledge and the tests themselves contain an essentially random subset of that content knowledge, in order to squeak our students' scores up, we're encouraged to try to cover as many of the topics as possible.
The result is higher scores, for sure. Not much higher, since the fundamental skills necessary to ace a test are taught over a series of years, not in a few months, but measurably higher. Failure to create this little bump or worse, turning up in the numbers as a teacher whose students' gains are lower than average, can be a problem in your career, and that's only going to get worse as the emphasis on "value-added teaching" increases.
So, in order to be seen externally as a good teacher, you have to engage in crappy teaching. Spend too much time teaching your kids to think critically and reflectively, and you'll get identified by your district as a poor teacher. Your kids will do better in college and in life, but you'll sacrifice yourself in the process.
And they wonder why good teachers often don't feel like they can teach capably and authentically within our system. What really, really stinks is that our highest risk districts are going to feel the brunt of this misplacement of priorities.
