One or two projected at the end of a class session is fine. You may wish to project these Next-Time Questions rather than post them. When friends weren’t helpful, I’d suggest they seek new friends! It is in such discussions that learning takes place. When they’d ask for early “official” answers, I’d tell them to confer with friends. In my experience students have benefited by the discussions, and sometimes arguments, about answers to many of these questions. Taking this easy and careless route misses your opportunity for increased student learning to occur. But please, DO NOT show the answers to these in the same class period where the question is posed!!! Do not use these as quickie quizzes with short wait times in your lecture. Their educational value is the long wait time!Īlthough these are copyrighted, teachers are free to download any or all of them for sharing with their students. My hope is that teachers will pose the questions, and withhold answers to “next time,” which could be as early as the next class meeting. They have also been in ancillaries to my Conceptual Physics textbooks, and physical science textbooks as well. Most of these have been published over the years as Figuring Physics in The Physics Teacher magazine. Diffraction, Polarization & Interference.
