I thought the lecture was very informative. There were I lot of things I never knew I needed to know, and without this lecture I would have fallen beyond. Now I feel I somewhat have an idea of what is going on.
I have mixed feelings about the chalk and wire thing. I already feel poor after I just signed up for our PPST test, and now thinking about all the other expenses I'm going to have before I start making the big bucks as a teacher...I'd almost rather make one by hand as a hard copy and have it right in front of me. I like the organization of the online one, but sometimes those can be confusing as well.
