Perhaps another use for teaching skill would be to allow for the training of other characters' stats. There would be a teaching skill requirement as well as a requirement for having a higher value in the stat that the student is trying to learn (and the student needs the requisite TDP's of course). So instead of trying to find a stat training area in the town you're in, you could get someone to train you in that stat. Sort of like going to a weight-lifting coach to improve your strength.
