1. Reread Chapter 5
– carefully
2. Design a lesson
and mini-experiment for a Discover-a- Relationship objective from the Unit
Draft, and modify the Unit Plan if there is a need. For more details consult
Activity 5.7 p.202, Activity 5.8 p.202, Synthesis Activity #3 p.206.

3. In your journal describe the stages of
discover-a-relationship lesson.
The stages of discover-a-relationship lessons are the following:
Stage 1: Experimenting
In this stage, students are given some activity, tasksheet,
etc., in which they are led to experiment with concepts related to the targeted
relationship. The teacher’s role is to facilitate the activity, ask stimulating
questions, and help guide students who are having trouble.
Stage 2: Reflecting and
Explaining
In this stage, students will examine the outcomes of their
experiments and attempt to draw meaningful conjectures based on their findings.
Students will verbalize their ideas. The teacher’s role is to guide these
discussions and ask probing questions.
Stage 3: Hypothesizing and
Articulating
In this stage, students attempt to formulate and verbalize their
ideas about possible relationships based on the analyses of their experiments.
The teacher’s role is to guide students to further think about and test these
ideas.
Stage 4: Verifying and
Refining
In this stage, students will try to justify or disprove their
ideas about relationships (this justification may be informal verification or
formal proofs). If there is reason to believe a proposition isn’t correct, the
class will attempt to formulate new propositions, and again test these. The
teacher’s role is to guide this cycle of refining propositions until the class
can agree upon a proposition about the relationship.
4. Express anything that you find
confusing about the construct-a-concept or the discover-a-relationship
learning levels. (Note that, as is customary in Mathematics, ``or"
is inclusive.)
The biggest confusion I have
with both types of lessons is how to
conduct the discussions. The learning levels make sense to me, and the stages
of the lessons are logical, but I am a little bit overwhelmed with the thought
of leading a discussion within these lessons. It is easy enough to say what you
want to accomplish during the discussion, but an entirely different matter to
actually conduct it.
5. If you have not already, please: Find
a middle or high schooler and engage them in an interview as described in
Synthesis Activity #5 p. 171.
A.
If it were
not a required subject, would you choose to study mathematics? Why or why not?
“Yes, because it was the
easiest subject for me. Once you got it, you got it, and then you were done. It
really depends on the teacher, though. When I have a bad teacher, I don’t enjoy
it at all, so I wouldn’t choose to take it in that case. But when I have a good
teacher, I love my math classes; they just make sense.”
B.
Is
mathematics more or less interesting than other school subjects you take? Why?
“I wouldn’t say it’s incredibly interesting to me, but I enjoy learning
it and solving problems because it makes sense and you can do it over and over
again. I’ve never learned applied math really, I’ve just learned how to solve
problems and deal with equations and things like that. I’ve never taken stats
or logic because I’d rather take the classes that are numbers, numbers,
numbers. I like things that are right or wrong.”
C.
Is
mathematics more or less difficult to learn than other school subjects? Why?
“Less difficult, because once
you’ve seen it done you can work through it on your own; it’s totally
replication. I like that it builds and I can apply what I’ve learned to what
I’ll learn next in the class – other classes are a lot of new concepts piled on
and on. Once you know you can do something in math, you can do it over and over
again.”
D.
From where
do you think the mathematics we study in school comes? Explain why you believe
what you just told me.
“I think it comes from mathematicians
who spend their life trying to study a concept and then come up with a formula,
and prove things that actually work. Just like science: it comes from people
who devote their lives to studying it and then come up with a system of
rules. I think this way because I
remember having to do a report about a mathematician and what things they were
working with when they came up with equations and things. I’ve never really
learned stuff like this in class though, besides this paper.”
E.
What do
the words “mathematical research” bring to your mind?
“A lot of white boards,
plugging and chugging, calculators, a lot of computers running, seeing if
things work out. It makes me think of The
Life of Pi when he just writes out all the digits of pi on a blackboard for
hours. I picture people in white coats having a problem and siting in front of
it and trying to apply the rules that they know figure out new things. I
picture everything taking a lot of time. But I kind of feel like this doesn’t
happen anymore because it’s all figured out.”
F.
Tell me
what you know about any one of the following people: Pythagoras, Euclid,
Hypatia, Rene Descartes, Maria Agnesi, Isaac Newton, or Andrew Wiles.
“I know a lot about Newton because I took physics. I know Newton’s three
laws, but I’m not sure how those apply to math. I learned that Newton had an
apple fall on his head and ‘what goes up must come down.’ Pythagorus goes with
the Pythagorean theorem, dealing with triangles.”
G.
What is
the easiest thing about learning mathematics?
“ Usually there’s only one
answer, so you know you’re done when you have one answer. With writing a paper
or something like that, you could go on and on. With math, you just follow the
steps you’re given and get the answer; your hand is basically held, there’s not
creativity. You just follow step one, step two, step three… If you learn how to
problem solve, there are no curve balls because you know how to read a question
and follow a pattern.”
H.
What is
the hardest thing about learning mathematics?
“It takes time. If you really
want it to be natural, you have to spend LOT of time. Also, when one of my
teachers took away our calculators, it was SUCH a handicap. I second-guessed
myself at everything and it took me ages to do by hand. It’s almost like relearning
it because you have to start from the ground up again. The calculator just does
it for you; you don’t have to remember rules or anything anymore. But I think
that’s good because it makes you really have to learn the material on your own.”
I.
What is
the most interesting thing about doing mathematics?
“I think it’s interesting how many different answers you can get when you
make mistakes. Even a little mistake in the beginning can make a HUGE
difference in the outcome of the number.
Little mistakes are incredibly important in math. Even things like
radians and degrees, I still don’t get the difference. Math takes a lot of
focus and attention to detail.”
J.
What is
the most boring thing about doing mathematics?
“Not knowing how math is
supposed to fit in. I enjoy doing it, but sometimes it gets to the point where
I feel like I’ve been doing this exact same problems for several weeks, just
with different numbers. I think there could be more mixing it in with history,
or something to make it applicable. That isn’t my teacher’s strong point, it’s
always like: this is the formula we’re using, and this is the type of problem
you use it for.”
K.
Do you
read your mathematics textbook differently from the way you read textbooks for
your other subjects?
“Yes definitely. With other
subjects I read everything because
everything is necessary. With math textbooks, I only need the examples because
I really don’t care about anything else; I just need to see the process to do
it so I can replicate it. There’s a lot of skimming to try to find out what’s
important.”
L.
How often
and for what reasons do you use mathematics outside of school-related work?
“I use it a lot for cooking, doubling or
halving recipes; I really like to cook and bake. I use a lot of simple math for
change and tips and stuff. It’s all really simple, I never use any of the
formulas. Sometimes I help people with stuff, like tutoring. I want to be a
nurse, so maybe using statistics for doses and stuff would be applicable
someday.”
I found the interview to be particularly interesting. Notice that this student enjoys math because s/he seems to like to "replicate" examples and "when you're done, you're done", etc. There is a vicious cycle going on in math education: the students who "like math" because they enjoy rote memorization are the ones who tend to become math teachers, not realizing that their relationship to mathematics is not at all the relationship that a mathematician has to the subject. Hence, we've created a situation where math has been terribly mis-represented to students.
ReplyDeleteAmanda,
ReplyDeleteI was also intrigued by the interview. I was amazed at how much this student's responses lined up with the problems in math education that we've been talking about in class. I'm sure I had some of the same attitudes when I was in high school, but it's been so long and my attitudes have changed so much that I forget how blatant the problem is!
