This system is very effective in high school. Any high school teachers in Tennessee who want to network or find out more, please let me know. It is taking off in the Alcoa City and Maryville City School systems and we are having interest from a local college and their teacher preparation program. PT is an unbelievable tool and is the best instuctional/management system I have found in 21 years of teaching! High school kids really do like it and readily admit that it helps them. The best thing though (and the most selfish thing) is that it really, really helps me!
