Activity 6.2 Videos on Problem Solving
Activity 6.2 Videos on Problem Solving
After
watching the two videos, I made a personal connection with the second, The Marshmallow Challenge. I took the
geometry seminar MA 501 in the spring of 2013,
current or future teachers of mathematics, taught by Dr. Lee from the math
department. I struggled the entire
semester, working hard, asking for much needed help from the professor, fellow
students, and my son who was in graduate school getting his PhD in mathematics
at the University of Iowa. For my Rank 1 teaching certification in STEM, I had to declare an area
of emphasis. Since my adviser's specialty is math, she declared my content area to be secondary mathematics, thus, I am required to take classes in my content area. I do not have a BA or MA in mathematics, I took basic math
classes in high school, and general education and math education classes as an
undergraduate. Being a novice, I was
terrified that I was in way over my head, since all of my classmates were getting
math degrees and/or were currently, math teachers in middle and/or high school.
One student, Jane, an expert, could
answer any of the questions in class and was so confident that she often worked
on her weekly lesson plans. Jane sat in front of me and would often check to see if I understood the concepts. I felt intimidated by
her, but appreciated her help. The class worked in pairs or small groups often.
We spent much of our time problem solving using various manipulatives. I realized that I was good at building the various structures because they
were concrete models rather than abstract theorems. Jane was better with the
abstract theorems. I was able to show her and explain how to construct the models
rather than the abstractions. I was surprised that this was difficult for her, but I felt good about being able to help her and about my abilities and strengths. I have more of an engineering
mind, and can often build things, and fix broken systems and small or large appliances
because I "see" how things work. My father was an engineer and so is my brother,
I never received the formal training, that is why I choose the STEM field of study.
It was
interesting to me that the architects and engineers (experts) did the best on the
“Marshmallow Challenge,” because I think I would do well with that challenge. Pretz, Naples & Sternberg (2003) discuss the differences
between novices and experts when looking at solving problems,
noting that researchers, Frencsh & Sternberg, found that “experts'
entrenched strategies interfered with rather than facilitated their
performance” (p. 15). I think that is why I, a novice, compared to Jane, an
expert who has “developed such a highly specialized body of knowledge” (p. 15),
am able to see the forest for the trees
when it comes to simple concrete problem solving. In the case of the
Marshmallow Challenge, kindergarteners (novices) outperformed all groups except
the architects and engineers (experts). Engineers and kindergarteners, often share
and work together with their peers, spending much of their time in cooperative
groups, solving problems, whether it be putting away toys, or designing the
next great solution to an important global issue.
