Re: [Phys-l] Unit Conversions (was Mass and Energy)



Please do let us know which problems you see. We all know that some aspects
of Piaget are not quite right. However his ideas have been used to
successfully design pedagogical interventions.

Sometimes when you have discomfort with an idea it is because the
concept
does not agree with your existing conceptions. This happens when
students
confront NTN3. The are uncomfortable with it and find it confusing
despite
the fact that it is actually quite simple and straightforward. It could
also be that the concept is wrong, so your discomfort comes from being
required to learn something that is not correct.

My goodness, John, have you no curiosity about what my discomfort
is, and what background I might have in understanding Piaget's ideas?

Hi all-
As I understand the discussion so far, Rick is expressing a
discomfort with many of John C.'s postings, a discomfort that I happen
to
share. John essentially finesses the issue by arguing that Rick is too
smart to understand it. I would be delighted if Rick could restate his
discomfort - if discomfort it is - in a way that prompts John to
address
the source of discomfort.
On the other hand, I may be misunderstanding the discussion. Am
I/
Regards,
Jack

You are in the fortunate 5% who achieved a high level of understanding
as a
result of both life experiences and school. Remember that at one time
only
the upper 20% or less went to college, so that colleges had a much
higher
proportion of formal operational students. My comment about factor
label is
that it did not help students to achieve a higher degree of thinking.
But
if you are already able to understand ratios, you will immediately
grasp
factor label. My comments are aimed at why the large percentage of
students
do not come to good understanding of math and science.
