This week in my "Teaching in Mathematics" class
we focused on a student's ability and process in problem solving. Problem
solving
questions are most often the hardest questions for student to complete
and/or understand. The most common phrases from students during problem solving
are "I don't get it!", "What are we doing!", "What's
the answer!" and the worst one "I give up!". My teacher
presented us with "Skyscraper" math problems and let me tell you, the
atmosphere in our classroom full of adult Teacher Candidates was not much
different from a class full of students. To give a brief summary of the
Skyscraper problem, the students are given a handout with a square grid (can be
2x2 and up) and on the sides of the grid each square is labeled with a number
as pictured here in this 4x4 example:

We were given linking cubes by our teacher and were
instructed to find the number of cubes needed on each square in order to
represent the numbers on the side of the square. Huh? Exactly my thoughts! Well
our only clue was that this problem is similar to Sudoku puzzles where a single
number can only be represented once in each row and column. Our group started
to build our towers for each square and right away I noticed our different approaches
to solving this problem. I had taken the blocks and built the required number
of buildings to fill the grid. Based on the Sudoku clue I knew that for a 4x4
grid we needed 4 buildings of each height (4 cubes tall, 3 cubes, 2 cubes, 1
cube). I needed to see what we were working with before I made decisions about where
to place these buildings where as my group members were placing cubes right on
the grid linking new heights and taking cubes away as they filled the grid. Once
our group had reached the point of frustration, we asked our teacher for help
and she explained that we should be looking to count the number of "pop
out" cubes from the top. We attempted from this perspective for a while
with no progress. In the end we did solve the problem by taking on a different
view and counting the visible faces of the cubes. Once we knew the key to this
puzzle we jumped from the 3x3 grid straight to the 5x5 and by applying our accrued
knowledge completed it with ease. Now that we fully understood the problem we
also realized that we could add one block to each building and have the same
correct answer.
The same
process and results can be seen in any problem solving situation, the goal for
us teachers to is change the negative phrases I mentioned earlier to more
positive and hopeful questions such as "What can I do next?",
"What would happen if..?". The issue we should be focusing on is not
that the student is struggling; it is how they react and overcome the struggle.
My university math professor would say to us "struggle is good" and
we would all laugh and possibly cry at the thought of working through some of
those calculus problems but in the end I know that he was right. Whenever I had
a question I found impossible, it challenged me to think creatively, try new
things and not give up. Also for the people reading this saying "I
hate math I would have given up eventually" rest assured I did not
solve all of those impossible questions and I did get the answer from my
friends or the professor but it was because of my initial struggle and failed
attempts that I understood the
problem and the solution. Know that this can be applied to any subject or any
problem in general. Before students give up or are told the answer they
continue to learn as long as they make an attempt, success or fail they are
gaining understanding through experience. This message I am sending is deeply
related to the Constructivist Learning Theory in which "the core idea is
that learners actively construct their own understandings, rather than absorb
what they are told or copy what someone shows them" (The Problem-Solving Cycle: Professional Development for
Middle School Mathematics Teachers The Facilitator’s Guide, 2003).
This week I leave you with this video that explains
the answers are never easy, we have to grow in our experiences and whether it
is in something you hate or something you love it is possible for everyone
learn.

ReplyDeleteHi Stefanie,
First off I just want to say I really like your blog design and how you incorporated Finding Nemo, as I find the quote “just keep swimming” very fitting for the problem solving process. I also like how you explained the Skyscraper activity and related it to the importance of giving students the chance to struggle. I know that when I was attempting to complete this problem with my group as an adult teacher candidate I got to the point where I was frustrated and wanted help, but as a group we never gave up and after a few hints we were able to solve the problem. In my future classrooms I want to incorporate problem solving questions like this one, to encourage students to collaborate and work through math problems together.
Another thing I really liked from your blog was when you shared that your university math professor said to your class “struggle is good”. I was never told this when I was a student and I always equated struggle with failure. I do not want any of my students to feel like they are not intelligent or capable of success because they are struggling a little bit. I am definitely going to tell my future students that “struggle is good” as a way of encouraging the problem solving process. Another take away point I got from your blog was from the video. Near the end of the video the narrator says “failing is just another word for learning”. I think this is such a positive message and I want to re-assure my students that failing is okay, as long as it is followed up trying again.
I looking forward to reading more of your posts throughout the semester,
Jodi
