Hi Pamela, You are using your "common sense" and many years of observing people when you talk about "tuning" in on your students. Many times instructors don't think that they have the skills to be teachers when they are first starting out after being in their career field for many years so they check their common sense at the school house door. A big mistake. That common sense serves instructors very well as it has gotten them this far in their careers. By having a personal professional development plan you can move from being a just a subject matter expert (SME) to an instructional delivery expert (IDE) as well. Keep up the good work. Gary
