I subscribe to Seth Godin's blog and in January he wrote a post called Measuring Nothing (with Great Accuracy). Because we are in the middle of implementing a new teacher evaluation system in our district which must include student growth goals, I could immediately identify.
I can show that my students are learning. The easiest attributes to measure are not the most important ones, though. I want my students to persevere when a task is hard and be respectful to adults and other children. I want to know that they will be successful adults some day.
I don't think this is on the test.
