Background Information
The students with the lowest mathematics ability who take beginning
algebra over the longer time frame suffer from poor comprehension skills and
high failure rates. The students who do
pass beginning algebra and eventually go on to a second-year algebra course
(advanced algebra, also known as algebra 2) find themselves struggling there in
part due to weak basic algebra skills.
When students fail classes, it breaks their potential for success. It interferes with the natural, seamless
progression of mathematics courses because students who fail mathematics
courses must often wait a semester before they can take a repeat course in the
summer. Failing mathematics courses also
undermines student confidence where it is already low due to poor ability and
comprehension.
Teachers and administrators alike are troubled by student performance in
algebra. They have expressed a strong
desire to change this slow, growing, negative development. It is apparent that a break from the
exclusive use of traditional methodologies and a change of pedagogy is in
order.
Potential Solutions
Many schools across the country are trying to overcome educational
problems with Mexican-American students (Henderson & Landesman, 1992). The similar conditions are: incoming students
with low ability and substandard confidence that result in a high number of
failures and dropouts, poor achievement on standardized tests, and possible
behavior problems in and out of school.
Steps can be taken to break this impasse. Educational pedagogy must be broad enough to
encompass the many learning styles of students.
Teaching methods under a holistic approach can include incorporating
visual tools and models, utilizing hands-on lessons, allowing cultural
connections, acknowledging the multiple-intelligences of every student, and
advocating gaming both inside and outside of school.
There are plenty of ways to approach visualization within algebra even
though it may seem to be a strictly numerical field of mathematics. Algebra lends itself well to the visual
learner. This suits Mexican-American
students because they possess a field dependant cognitive style (Henderson
& Landesman, 1992).
Field dependence is a type of learning preference. Students who are field dependent learn best
with group situations and when presented with a high degree of
organization. They also do well when their
environment is structured and material is visually presented (Didkovskaya,
n.d.).
Calculators that perform visual representations of equations exist and
can help provide simple methods for teaching what many students find to be
troublesome in a format that can help Hispanic students, especially when the
population is field dependent.
For instance, a lecture-based approach to teaching factoring would have
students finding patterns with numbers.
When students first learn to factor they must find a pair of numbers
that multiply to a certain product and add to a certain sum. It is a relatively simple game at first that
many students can successfully accomplish if they possess a great deal of
number sense, which has been gained by memorizing multiplication tables and
playing like games in the past.
However, for students who do not possess such skills or have not had the
benefit of playing number games, factoring is laborious. It frustrates these students because it
exists as a number game that they cannot begin to appreciate, in part do to its
lack of relevance to their lives. To
side step this dilemma, teachers may use graphing calculators and/or algebra
tiles.
Graphing calculators allow students to see connections from graphing
semi-complex polynomials to transforming them into the binomial factors they
need to find. Through the use of
graphing calculators, students can find special points on the graphs of these
polynomials to factor trinomials, be successful at it, and even find the
process to be meaningful. As is often
the case with meaningful lessons, the endeavor also lends itself to further
work with factoring much more complicated polynomials and solving equations
that involve polynomials.
There are numerous hands-on ‘discovery’ lessons that can be used to
demonstrate mathematical properties and expedite learning not otherwise gained
from non-calculator use (Gage, 1999).
Besides visual models that can demonstrate proportionality possibly
through the use of similar figures or lengths of shadows and the triangles they
form, there is a technique used by biologists to count fish that involves
proportions. By actually mimicking the
process that biologists use to tag, release and capture fish using a physical
model to create a mathematical model, students can appreciate and thereby
understand exactly what they are doing and why they are doing it. It provides a complete picture of the full
process that might otherwise escape the learner who is taught without the context. Furthermore, it promotes a healthy classroom
environment.
Graphing
calculators help students visualize problems, discover mathematical theorems on
their own, instantly check the validity of their answers, test out their own
hypotheses, and explore different ways of solving problems. Graphing
calculators allow topics to be discovered by students on their own, even before
the teacher formally introduces them. They facilitate an active approach to
learning, converting a classroom from a place where students sit back passively
listening to the instructor, to one where students work with their classmates
and produce their own ideas and solutions. Graphing calculators improve
communication among students, and they allow students a faster, better way to
produce graphs. (Pomerantz, 1997)
In fact, it is believed that no learner truly learns unless it is done
from within one’s culture (Nieto, 1999).
Therefore, teachers may include lessons that use elements of student
culture. Since Morton East is
predominantly Hispanic, math lessons can include Mexican art, dance, cuisine,
and music.
Although it may be extremely difficult to conduct complete algebra
lessons using art, dance, cuisine and music, it would be extremely simple to
introduce topics that way. For instance,
to begin discussion on rational expressions, students must understand how to
use fractions. One could easily produce
a Mexican recipe to demonstrate fractions and proportions that would have
students ready to accept a higher order of algebra for work on rational
expressions.
There is a school of thought that says challenges with language affects
mathematics comprehension. Hispanic
students arrive at common misconceptions in mathematics similar to Anglos but
with a greater frequency due to language deficiencies (Mestre, 1999). To address the problem, teachers must alter
pedagogy and break free from a teacher-centered classroom, which will be
handled more closely within the section Implementing
Solutions below.
Teachers who maximize their potential as educators,
act as facilitators. They vary the
delivery methods and make use of techniques that are receptive to all
learners. According to
The Multiple Intelligence model has suggests vehicles
teachers can use that students can also enjoy.
The vehicles are games, which can be found with many software products
and physical games. Games cross many
dimensions with
One game specifically worth mentioning that is useful for a broad range
of ages is the game of Chess. The game

To promote continued growth at
Morton East teachers are very collegial and the mathematics department
is no exception. Like similar schools
that have encountered problems dealing with its population, the change to occur
in order to reach beneficial results in student performance is not about
teacher motivation nor is it about teacher ability. The problem is specific to technique and
knowing the student population.
The teacher toolbox may never be completely full of strategies and
ideas, but a method for encouraging the sharing of productive work, cleaver
ideas, and success lesson plans is a necessity.
Teachers have adopted portfolios as a means for students to mark
progress, invite dialogue, identify personal traits or goals, and offer a tool for
reflection (NCREL, n.d.). Since this
activity can be beneficial for students, it can be equally beneficial for
teachers and the educational leaders who adopt such activities.
The record keeping of work is not a new concept, but as a departmental
or possibly interdepartmental activity, it can be used as a tool for
constructive criticism between professionals.
Such a tool would help determine what is best for the population being
served, the teachers who serve the population, and the leadership that guides
the institution. A portfolio could be
extremely extensive and hit a complete index of topics or generic and be an
open, less detailed venue, as the situation may require.
To facilitate the use and growth of a departmental and/or
interdepartmental portfolio system, one could invite an incentive program. Teachers who become engaged in the
development of the portfolio system could be offered 1) a positive mention
within formal observation reports, 2) recognition at school meetings, or 3)
curriculum compensation to promote the portfolio, 4) credits (CPDUs) toward
state recertification, or 5) a stipend toward certification costs.
Another avenue to promote institutional growth is teacher training. The leadership in education speaks of
student-centered classrooms, teachers as facilitators and using cognitive
techniques within instruction. This
model is akin to the practice of Socrates (Nenney, 2001). The teacher evokes higher order thinking and
understanding from the students and does not necessarily deliver it as a neat,
complete package. It is a strategy used
to promote independence, personal confidence and propagate dialogue conducive
for a democracy (Reich, 1998).
Student-centered classrooms, where teachers evoke knowledge from
students instead of hand-delivering it, invites
Creating an Atmosphere for Continuous Growth
Site research brings a level of professionalism and legitimacy to
education that it deserves. It indicates
to administrators, teachers, students and community members alike that
continual growth comes from learning and serves as a model for education. The act of basing decision-making and
practice on research informs participants within education that learning is
important and our understanding of it is limited, which facilitates the need
for research as a cyclical, self-perpetuating event.
The Hawthorne Effect that arose from the study of a Western Electric
plant in
The method of perpetuating educational research can be accomplished
through the use of institutional portfolios.
Institutional portfolios would serve as a means for producing anecdotal
artifacts for the process of continued research. They would direct serious research toward
target problems generated by the specific artifacts and the reflections made as
a result of them.
Conclusion
Education in the 21st Century is beginning to reflect the
changes made in the late 20th Century. Due to the nature in which information and
society changes, education has abandoned hard-fast rules in academia. It is leaning toward process, communication,
critical thinking, and other generalized skills that closely reflect
Within mathematics education, there are tools to remain current with
these changes. Graphing calculators
allow what Gage describes as learning that moves faster due to the removal of
cumbersome and time-consuming tasks.
This would appear to serve Hispanic populations that suffer from lower
abilities and consequently need to catch up to their peers in other communities.
As schools target
Such an institutional model will serve our ultimate societal goal of
maintaining a healthy democracy.
Hispanic students will assimilate into American society if they can
continue achievement. Achievement
depends, in part, on fostering a firm grasp of mathematics -- specifically
algebra -- as it pertains to exercising critical thinking, communication,
properties of the world around them, and reasoning. By providing Hispanics and populations with
similar hurdles a meaningful, understandable framework for learning algebra,
