Some of the postings I've been reading lately reflect a doctrinaire self-righteousness that doesn't seem very helpful. I don't think that any of us have all the answers, neither those who ridicule anyone who supports teaching skills or those who attack anyone who is considering new methods and approaches. Most of the good math teachers I know (and there are a lot of these around) are struggling with what to retain and what to change, how to incorporate technology wisely, where data analysis fits in, what topics are, in fact, expendable. We are weighing priorities. We recognize that we can't do it all and we need to have the humility to realize that we may make mistakes. For better or for worse, we are living in a time of real change and the fact that people are all over the place, going in different directions and investigating different approaches is a source of strength. A lot of useful ideas will emerge out of all this and we need to be open enough to recognize the good stuff.
