TEACHING
MATHEMATICS WORD PROBLEM SOLVING TO DEAF STUDENTS
COMETS
WORKSHOP
Review of
the Literature:
WORKSHOP
Before
the workshop,
1) Have teachers
read the Problem Solving Workshop: Pre-readings
2) Have each
teacher participant bring some element from their regular math curriculum--lesson
plans, text, etc. to be used during the workshop.
3) For
the Leader
- Introduction
The leader
identifies that in today's workshop, the emphasis will be on using
familiar curriculum but in a new way, to structure lessons for problem-solving
strategies. The goal of the workshop is that everyone leaves with
a MODEL that can be transferred to their entire math curriculum
as they teach it for the remainder of the year.
1. The leader
then explains that the teaching of problem-solving will follow a
3-part framework, that we will illustrate during the session. The
three parts of this problem-solving sequence involve:
-
Teaching
the particular problem-solution , perhaps using math materials,
employing a set of strategies to be explained
-
Metacognitive
discussion, to be explained further
- Application
of the strategy to a new context , sometimes working independently.
On an adult
level, the leader then provides the group with a single, interesting,
and challenging problem from mathematics, preferably a challenging
word problem.
2. The group
is divided into working pairs of teacher-participants who are given
the task of generating at least two more if there is time) explanations
of what the real problem is (Problem-identification).
3. Pairs then
share with the large group what they believe the real core problem
to be; through large-group discussion, consensus is reached on the
core problem, and it is written clearly by the leader for the group
to see.
4. As a large
group, ideas are solicited for what
may be some workable alternative ways to go about the solution --not
yet trying to solve the problem, but just discussing the OPTIONS
for some possibly fruitful avenues to pursue. Preferably, three
solution paths would be identified by the large group (Choosing
Solutions).
5. Divide the
larger group into three sub-groups or teams, and each group then
tries to carry out the actual solution according to one solution
path; thus each of the teams has a different solution path which
they are testing (Executing the Plan). At this stage, it
is VERY important that the groups not only carry out their respective
plans, but also make notes about the processes used; appointing
one member of each group as a recorder will facilitate this process.
A group chair should also be appointed.The recorder can note also
the "false" starts that the group makes as well.
6. At this
point, the chairs of each of the three teams use their recorder's
notes to report on their team's solution success by including these
several steps:
- Explain
the solution process and whether it worked or not.
- Illustrate
the process, by writing out on a smartboard or some other medium
that the whole group can see, the steps or the algorithms used.
- Description
of what did NOT work, and WHY.
- Encourage
commentary from the larger group.
7. The large
group then discusses whether more than one solution path is usable
in this particular problem. The larger group then discusses the
process to be used to CHECK the answer for accuracy (Checking
the Answer). A set of steps is listed.
8. Now is
the opportunity to engage in reflection or
METACOGNITION. The leader should explain that there are at least
two dimensions to metacognition:
- Task-oriented
in relation to monitoring the solution to the particular problem
(in this case the math problem), and
- Sstrategic
in terms of the selection of a particular strategy which may
go beyond the immediate particular problem (Presseisen,
2001).
Research
on deaf learners indicates that the current strategies which
are used to teach reading to deaf learners may actually hinder
the development of mature metacognitive knowledge, that the
low-level reading material that is often given to deaf children
may not give them opportunity to develop and practice metacognition,
and that deaf students in fact CAN benefit from metacognitive
strategy instruction (Strassman,
1997). Martin,
Craft, and Zheng (2001) found also that deaf learners
in three different countries could carry out metacognitive
discussions and gain insights into their problem-solving processes.
9. The leader
should now ask participants to reflect on the solution which they
selected and the PROCESSES that they used, building around
the questions:
-
What
methods did you use in the solution?
-
Why
did you use those methods?
-
If you
were to approach a similar problem tomorrow, what would you
do differently? The same? Why?
- How
will you approach the next problem you have in math, based on
this experience?
10. The larger
group now discusses the question, "Where else in life are these
general strategies useful?" This is known as TRANSFER,
moving the participants out from math per se, to applying these
strategies in new non-math contexts.
Examples could be making difficult decisions such as seeking a job,
purchasing a car, negotiating a reconciliation when two friends
have had a serious disagreement, etc.
11. Each individual
participant is now asked to take the math curriculum element which
they brought with them and select one teaching episode or lesson
topic, and then work individually to construct a lesson plan which
uses these same strategies which the whole group has just demonstrated
and participated in, during this workshop
- problem
identification,
- choice
of solutions,
- executing
a plan,
- checking
the answer,
- reflecting
on the processes used.
12. Individual
participants then share their lesson plans with one partner, for
comparison and also feedback and editing.
13. The large
group then comes together again and with the help of the Leader,
lists some principles learned from writing the lesson plans as well
as from the whole session. This effort is to identify what is COMMON
across the various lesson plans, whose actual topics will be probably
quite varied.
14. Thus,
the experience of the workshop as a whole has demonstrated the three
fundamental steps of:
- developing
a strategy
- doing
metacognition
- and
making transfer
within the
first or strategy segment have been the basic steps of problem-identification,
the choice of solutions, executing the plan, and checking the
answers.
15. Final
discussion -- What will you do differently now in teaching mathematics?
This general sharing should confirm for everyone the primary thrust
of this workshop session.

Word Problem Solving Skills in Deaf Students
Do you have
a deaf student in your class? Are you searching for resources to
help your deaf student(s) improve word problem solving skills in
mathematics? Project SOLVE
is a web-based problem-solving mentoring system. Many different
algebra and introductory college-level math problems are being placed
on the web with various help menus to guide the student in developing
skills.

Learning
to Think Mathematically: Problem Solving, Metacognition, and Sense-Making
in Mathematics
Alan Schoenfeld,
a leader in math problem solving, wrote this article, Learning to Think Mathematically: Problem Solving, Metacognition, and Sense-Making
in Mathematics. This article talks about a broad conceptualization
of what it means to think mathematically, to summarize the literature
relevant to understanding mathematical thinking and
problem solving, and to point to new directions in research, development
and assessment consonant with an emerging understanding of mathematical
thinking.

Board for sharing successful problem solving and other mathematics
education strategies.
