At SAIT Polytechnic, we use the Instructor Skills Workshop (ISW) training originally developed at a B.C. college (about 25 years ago).
ISW is a 24-hr training session which is available to new instructors, contract instructors,instructors needing a refresher; it's also part of our 80 hr Teaching Excellence Foundations (TEF) training offered to new hires every August.
TEF and ISW make use of the BOPPPS model (bridge in, objective, pre-assessment, participation, post-assessment, summary). Using the model goes a long way to addressing the problem you offer as an example. Is it a panacea for all teaching woes? No. Does it help? Yes.
