-
In what way, if
any, do you find students’ preconceptions about inertia help or hinder their
physics understanding?
-
In what way, if
any, do you explicitly address the non-physics definition of inertia and other
physics terms?
-
Do you continue
to focus on inertia as you move on to mechanics or do you simply focus on it
while covering Newton's First law? Why or why not?
-
When teaching
Newton's laws do you find it best to state them in terms of inertia,
acceleration and other physics concepts or do you prefer to word them in
"layperson's" terms? Explain.
-
What
interventions do you give your students to help them overcome misconceptions
about inertia?
-
How do you relate
inertia to real-life situations?
-
What specific
activities do you give your students when you discuss inertia?
-
What type of
evaluation do you think is best in assessing students' conceptual
understanding of inertia?
-
What
instructional strategy/strategies do you find the most effective in promoting
conceptual change among students in teaching inertia?
-
What classroom
activities do you provide your students in order to facilitate the integration
of their qualitative knowledge and quantitative knowledge in inertia
-
What are the
common difficulties you encounter in teaching inertia?
-
Most students
have an Aristotelian view of the world that is quite consistent with their
everyday experiences. What can an instructor in a large lecture class do
enable students to accommodate their everyday experiences into a Newtonian
framework?
-
Friction is
commonly introduced as a particular example of an external force. However,
students have been experiencing friction for a long time. If we begin our
discussion of forces and inertia with the inclusion of friction at the outset,
do you believe that this change in approach can facilitate students'
learning? Why or why not?
-
How is the
Aristotelian model of motion that I have seen most students demonstrate,
different from the impetus model that is often talked about in literature?
-
How do you go
about successfully changing the idea that a constant force is required to
maintain constant motion?
-
In looking at
constant acceleration in the case of freely falling objects,
do you think it
is necessary for students to work through thought experiments to understand
how it is logical that the acceleration of an object in free fall is
independent of mass, or does physically demonstrating this provide sufficient
understanding? Why or why not?
-
What are the
common misconceptions that students have concerning inertia?
-
What is the best
method of getting students to differentiate between inertia & weight?
-
Would you use
kinetic energy to teach about inertia? Why or why not?
-
Would you
introduce inertia with Newton’s first law? Why or why not?
-
Would you use
circular motion (rotation) to teach about inertia? Why or why not?
-
Would you
introduce inertia with mass? Why or why not?
-
Would you use
acceleration to teach about inertia? Why or why not?
-
Is it necessary
to talk about inertial reference frames in this level? If so, is there some
good examples to give them clear illustration?
-
How do you use
with other properties of matter, such as mass or weight to help students
understand the concept of inertia?
