Donna, A change of instructional style generally incorporates a change in instructional delivery. For example if your style is to deliver your content via a 2 hour lecture then a change of style might be to take the content from the lecture and reformat it to mini-lectures of 15-20 minutes and then have a small group activity, role play, case study or Q&A session. Then do another mini-lecture and a different activity. This way you are appealing to the different learning preferences of your students while using different instructional venues to deliver the content. Gary Gary Meers, Ed.D.
