When I reflect on the course, I think there's some value to mentioning the first few things that come to mind without flipping back through readings and blog posts as these are likely the most profound learnings I have taken away from the course
1) I recall in one of our early courses the discussion about what it means to have a deep understanding about something and the relevance of being able to express something in multiple ways. I know I ( and my students) have been frustrated at times with textbook questions that dictate how work should be shown, or ask for multiple representations of the same work or answer. I think this discussion helped me appreciate the value in not stopping as soon as one understanding is attained.
2) I appreciated the challenge of taking a few textbook questions and trying to 'open them up' as per the readings on the week we focused on problem solving. While my initial reading of the chapters had me thinking that they were trite and stating the obious, the challenge of re-writing and the discussions that ensured were valuable and brought up some ways to 'open up the questions' that I had not previously thought of.
Some burning questions...
1) How can assessment be fair (standardized?) yet still evaluate the softer skills fairly, while being possible to do with a courseload of 200 students?
2)How can we bring together the importance of practice and rote learning with the importance of student driven learning and abstract thought?
3) Will the new curriculum bring any real change to my classroom?

Esmonde - Ideas and Identities: Supporting Identity in Cooperative Mathematics Learning
In this review, Esmonde discusses how cooperative learning (CL)
might assist students to learn in mathematics classes. She acknowledges that CL
is an often recommended technique to increase equity in classes, but also that
the benefits (group harmony, learning academic content with social skills) can
also have detrimental effects (incorrect math strategies, undesirable social
interactions). I know that when I did my teacher education program (2005-2006),
cooperative education was certainly highly encouraged, and we discussed to
great length the challenges and possible successes of having students learn together
and/or teach each other in various cooperative organizations (random groupings,
jigsaw teachings etc.) In general, I apply cooperative learning strategies in
my classroom regularly. There are content-based and social based outcomes: students
enjoy working together; it breaks up monotony of math class; they receive multiple
options of ways to understand concepts; the teacher can circulate and have
discussions with small groups, thus getting to know students better. Furthermore,
I think we are providing students with valuable skills and messages that it’s
important to work together (and not just with friends) and that mathematical
learning and understanding is a process, which is often effective to discuss
conceptions and misconceptions in order to understand.
One of the questions Esmonde raises is how we might group
students. Do we group high achievers together so that they don’t dictate other
students’ learning practices, or do we create mixed groupings such that they
can teach each other? True
cooperative education might likely be more effective with groupings of similar
ability so that students can explore the concepts at levels that challenge and
are meaningful to them. On the flip side, it can be valuable for students to
learn from their peers – to see and understand how others have made sense of
the material, and valuable for highly able students to have to clearly
communicate their processes.
I’ve often considered this
problem, and my short-answer response is both: I think it’s important to change
up groupings often (and sometimes let them choose their own) so that both these
can happen. There is an undeniable possibility that students will copy off each
other and let the more able (or more driven) students do most of the work and
solve the problems, yet I have managed to come to terms with this by considering
that this form of education allows for multiple entry points, and the weaker
student may only be able to imitate the stronger student, but that there is
hopefully some learning in this.
QUESTION: Should
cooperative activities be evaluated in Math class? If so, how?

Does Everybody Count?
In her article discussing curricular reform, Noddings
questions the assumption that mathematics needs to be an emphasis for all
students and that math skills are something everyone needs. She suggests that
math courses might contribute more effectively to general education.
Through much of
her article, Noddings comes across somewhat like an educated but whiny student
asking “why do we need to learn this?”, arguing that technology has replaced
the need for things like
arithmetic skills. Later on in her article, she comes
across a bit like a whiny teacher suggesting that it
would be nice if teaching
was a “real profession, one like law and medicine.” (p. 101) She then
suggests that teacher would
not be willing to dedicate three or four years to graduate school for a
career
in which they have little autonomy, poor pay and low status.
I think one of
her main arguments is that there is not enough specific teacher education, and
that in
addition to being knowledgeable about their subject, a teacher should
be more highly trained in
education. I think I disagree with this! Even the one year I spent in my teacher
education program
seemed mostly time-filler. I think teachers need to learn
from practicums – I mentorship with an
experienced and able teacher is the most
appropriate way to learn our profession due to the fact that
there needs to be
a strong connection between the theoretical goals of education and the
practical
application of teaching within the constraints of the system we work
in (eg. 30 kids in a class for 75
minutes every other day etc.)
Question: What do
you think are key lessons people in a teacher education program need to learn?
How long should such a program be?

Response to Palme
In this article, Palme notes that teachers and textbook
companies are struggling with the development of school tasks that resemble out
of school situations. He criticizes traditional math word problems in lacking
realism and not being authentic. For example, a question involving an elevator
and a number of people does not take into account that people arrive at
different times, and the elevator would not always leave full. Palme attempts
to build a framework that will allow people to judge whether problems are real
and authentic.
In particular, he focuses on the inherent requirement in
problem solving to accept different interpretations of the problem and methods
of coming to solutions. He states, “The students must believe that their
solutions are going to be judged according to the requirements of the real life
situation and not have to think about what different requirements the teacher
might have.” In theory, this seems
logical to me, yet I question how it would work in practice for two reasons: 1)
if students over-simplify a problem, or always focus on simpler strategies such
as guess and check, they may miss learning important math concepts; 2)
Assessment becomes very complicated – it would be difficult to fairy assess the
validity of different solutions.
For my question, I will focus on a dilemma I recently had:
Recently, we had a question on a pre-calc 11 midterm where
students were given the perimeter and area of a rectangle and asked to find the
dimensions. The intent was that students would solve the perimeter equation for
one variable, substitute the expression into the area equation, then expand and
solve a quadratic equation. The question was worth 3 marks, and many students
who had partially correct students got part-marks on the question.
A few students used guess and check methods, and since this
is a valid strategy, I gave them full marks if they provided the correct solution. One student tried a guess and
check strategy, and came up with an answer that was close but not exactly the
solution – I gave him zero marks. He argued that he had partially completed a
legitimate strategy that other students received full marks for, and thus
should receive part marks.
Thoughts?

Response to New Questions for Old
In this chapter, the authors encourage teachers to optimize the use of their textbooks by opening questions up for students. They identify four ways to do so:
1) Change the existing question - in particular, adding or omitting a bit to the question to make it more open ended to encourage students to explore the material further. They give many examples such as instead of asking students to plot 3 points on a coordinate grid and decide if it is an isoceles triangle, ask students to plot 6 points, and determine all the isoceles triangles they can.
2) Give the answer rather than the question - for example, tell students the hypotenuse of a right angle triangle is 17, and ask them to list as many triangles as they can.
3) Change the resources - Allowing, or not allowing technology changes the scope of the question. For example, coming up with fractions equal to 1/3 with or without a calculator.
4) Change the format - ask questions in different ways. The authors provide a whole page of different ways to express an equation like 4x+2=10.
These methods do not seem particularly innovative to me. Just about every textbook I use applies all of these quite regularly, so I'm not sure what new questions I can offer by analyzing three questions, but I will try...
I choose to work with the Grade 10 McGraw Hill Ryerson text I currently use.
Question 1: Earth has a diameter of approximately 8000 mi. Land forms 29% of the surface of the Earth. Assume Earth is a sphere. Estimate the area of the land on earth.
This question could be opened up by giving different aspects of the information - for example stating the area of the land on earth and the diameter and asking for the percent covered. Alternately, students could be asked to compare their result (assuming Earth is spherical) and research how far off they are from the reality, given that Earth is not an exact sphere.
Question 2: Evaluate without a calculator: (3^(1/6))(3^(5/6))
Students could be asked to follow up by listing a few other rational powers of 3 they could multiply (3^(1/6) by that they would be able to evaluate without a calculator.
Question 3: A circus recently had a sold-out performance. There were varying admission prices. The admission for premium seating was $250 for adults and $175 for students. The total revenue for premium seating was $29 125. The receipts showed that 130 premium seats were sold. Determine how many adults and how many students were in premium seats.
Students could be asked if they could find any other combination of adult and student tickets that had the same revenue, or they could be asked to model the situation using graphing technology, or they could be asked to come up with another scenario that could also be modelled with the equations they came up with for this question.

Response to Teaching Mathematics for Understanding: An analysis of Lessons Submitted by Teachers Seeking NBPTS Certification
In this study, the researchers analyze portfolios submitted
by teacher candidates. They conclude that the lessons included many tasks involving
hands on activities or real world contexts and technology, multiperson
collaboration and hands-on material, but rarely required students to provide
explanations or demonstrate mathematical reasoning.
I wondered as I read this article how representative the
study would be. When I am in a job interview and asked to describe a lesson, I
generally describe a very hands-on activity such as building clinometers and
using them to measure heights as a way to make trigonometry meaningful. While I’m not misleading anyone, as I do run
this activity almost every year, it is the exception and not the rule in my
class, as I generally follow a fairly traditional lesson structure. Indeed, if
asked to provide a portfolio of my lessons, I would these ‘special’ lessons
which are not what the students in my classes experience most days. I would
suggest many other teachers might follow similar patterns.
The authors criticize that that tasks, while hopefully
engaging and meaningful, tend to have a ‘low frequency of high demand tasks’ in
exchange for a ‘higher incidence of innovative pedagogical features.’ This made
me think of two things: First, I often feel pressure to be ‘performing’ and ‘entertaining’
my classes, which I think does not need to be a teachers’ role. Secondly, particularly
with new curriculums coming into place, I hope math class remains challenging
as it is one of the last bastions of challenge (some) students have in schools.
Some of my students tell me they are used to getting near-perfect marks in most
other subjects simply for completing their work to an acceptable degree, with little
regard for quality. While I don’t mean
to torture students, I think part of what schools need to teach students is how
to work hard to achieve something that is difficult, and when we settle by
catering to a lowest common denominator, we may be robbing students of the
opportunity to have to work hard for something.
Finally, in their conclusion, the authors bring up the
concern of many studies including theirs focusing on classroom lessons and not
on assessment. For example, if teachers use methods of instruction that include
group work, hands on activities and technology, but their assessment focuses on
pencil and paper knowledge and problem solving, we are not being fair to
students. Indeed, lessons should prepare students for, and resemble,
assessment. Students get (rightfully) frustrated if they have done and
understood the coursework, yet are not able to be successful in assessments.
Question: How should policymakers determine appropriate
levels of difficulty for math classes?

Response to 'When Learning no longer matters: Standardized testing and the creation of inequality' (Boaler)
In this article, Boaler tells the story of a school in an underprivileged
area which has a forward thinking math department. The students demonstrate
strong increases in achievement and strong results on independently developed
forms of assessment, but still perform poorly on Standardized assessments.
Boaler outlines the damage that is done to students’ self esteem as they work
hard to achieve and feel like they have learned and understand, yet are still
told they are ‘below average’ on these high stakes assessments. If I had to
criticize the article, it would be that Boaler does not adequately describe the
practices the math department undertakes in order to increase students’
mathematical understanding. She non-specifically states that they observe each
other’s classes, meet regularly, and take part in professional development
opportunities, but I would have been interested in more specifics about their
teaching practices.
A stop for me in the article occurred when Boaler that students
might perform poorly on standardized assessments as they are set in contexts
that are confusing to linguistic-minority and low-income students. She gives an
example of the following question:
A cable crew had 120 feet of cable left on a 1,000 foot spool
after wiring 4 identical new homes. If the spool was full before the homes were
wired, which equation could be used to find the length of cable (x) used in
each home?
F. 4x + 120 = 1000
G. 4x - 120 = 1000
H. 4x = 1000
J. 4x - 1 000 = 120
This brought to mind the only high stakes provincial testing
we still have in BC – the Math 10 Provincial exam. All Grade 10 students write
a provincial math exam, but they are divided into one of two groups based on course
they are enrolled in – the Foundations/Pre-Calculus (FPC) class exam focuses
more on algebraic skills, and the exam reflects this. Alternately, the
Apprenticeship/Workplace (AW) exam, which usually attracts students who are
more challenged in math, features mostly extremely ‘wordy’ problems similar to
the one above. In my experience, students in the FPC course generally score
close to their term marks, but the majority of students fail the AW exam. I
believe the intention of the writers of the exam is that the math will make
more sense to students if it is put into context, but there is a disconnect and
students find reading the long problems challenging, and often don’t know how
to apply the math to the problem, even if they understand the mathematical concept.
Question: How can we put math concepts into meaningful concepts without overwhelming students with language and concepts they might not be familiar with (like spools and cable in the question above)
