Just finished it.
It's a great book, and I'll be blogging more about it later. It took a while to get through, because it was bus reading, and bus trips these days are pretty short ones. But Robert Moses has a lot of stories to tell*, and he has a great concept of making algebra meaningful to learners**. I'll definitely get back to this.
* as I observed to Morris Dees when I had the honor of meeting him at one of his talks, I appreciate his staying to fight the good fight, when that was more than I could do.
** and comparative anatomy informaticists as well. I am so going to cite his work in my anatomical algebra as I develop it.
