Most of these have
been published over the years as Figuring Physics in The Physics Teacher
magazine. They have also been in ancillaries to my Conceptual Physics
textbooks, and physical science textbooks as well. 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. Their educational value is the long wait
time!
Although these are copyrighted, teachers are free to download any or all of
them for sharing with their students. 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. Taking this
easy and careless route misses your opportunity for increased student
learning to occur. In my experience students have benefited by the
discussions, and sometimes arguments, about answers to many of these
questions. When they’d ask for early “official” answers, I’d tell them to
confer with friends. When friends weren’t helpful, I’d suggest they seek new
friends! It is in such discussions that learning takes place.
You may wish to project these Next-Time Questions rather than post them. One
or two projected at the end of a class session is fine. The answer is given
“next time” the class meets—or at some interval where wait time is at least
a day.
These Next-Time Questions are the outcome of my long and wonderful teaching
career. They’re yours at the click of a mouse. Please use them as I suggest.
