After
reading the title, I predict that the article will focus on students'
mathematical thinking. My
reading
of the first paragraph makes me realize that this article covers a
range of research ideas related to
learning and teaching math. The project coordinator, Wheeler,
publishes the proposals of Nesher, Bell,
and Gattegno, who are the co-authors of the article.
Among the three educators, Nesher seems to be most
concerned about interdisciplinary aspects
of
math acquisition. He points out that the general public is strongly
against “New Math” and demands “back
to basics” because students are struggling with New Math. She
wonders what makes math so difficult
for students to learn compared to how easily they learn and master
natural languages. She believes
that current research totally overlooks the cognitive processes
involved in learning math. To improve
the ways students learn math, she suggests that a new research
program examine the types of cognitive
processes involved in learning math “as a language system (p.27)”
in relation to its real-life interpretation
and practicality as well as artificial intelligence, psychology, and
sociology.On the other hand, Bell suggests a program that examines methods of teaching which may affect
students' understanding of math. The reason he chooses to look at the teaching aspect is that many
students cannot understand fully the math concepts taught in their lessons. He points out that many
students can add two positive numbers or two negative ones or subtract a larger negative number from a smaller negative one accurately. But, some fail to subtract a smaller negative number from a larger negative one (for example, -5 – -12) logically without using a number line. Lastly, she believes that research should look at ways of teaching which help students understand the meanings of the math concepts taught and eliminate their math misconceptions.
From a mathematician's perpective, Gattegno states
that the three “mother structures - order, algebra
and topological (p29)” are fundamental to the development of
classical math. He relates them to
the structures and activities of the human mind on which math
education needs to be based. He thinks
that students generally learn math through seeing, hearing and other
senses and that computer
technology
can improve their learning of math. Therefore, he believes that a
research program examining the effect of technology on students' ways of learning math can help develop a better math
curriculum.
I think all of the authors' perspectives are valid and
interesting. On the one hand, Nesher and Bell
have different focal points on math educational research. While
Nesher talks about the importance
of
learning math effectively, Bell emphasizes the instructional aspects
of math education. I believe that effective
learning cannot occur without effective teaching and vice versa. To
me, both are equally significant.
Since there is no single teaching method best for teaching all math
concepts, it is important to
examine a variety of teaching techniques to improve student learning.
In the same way, there is no one
method most effective in learning math. Since different students have
different learning styles, they can
develop multiple ways of learning math concepts. Their preferred
learning methods may shape lesson
planning and class activities. On the other hand, Nesher and Gattegno
consider math education from
interdisciplinary views on their research interests which focus on
cognitive processes and computer
technology. These aspects are certainly important. Today's technology
is more advanced than
when this article was published. The use of computers can certainly
increase students' interest and understanding
of math. In terms cognition, if we think about how children think
mathematically through
task-based interviews, we can come up with different ways of teaching
the subject in a fun-filled
manner.
It is interesting to note Nesher's interests in including interdisciplinary efforts to research programs in mathematics education. I think that Kilpatrick had a very different view on this. Kilpatrick seems to dismiss worthy research findings coming out of researchers who were not part of the research community of the mathematics education. I find this troubling. Kilpatrick's reasons for dismissing these findings are because "they do not partake of issues that concern this community; they do not arise from common concerns, shared knowledge, mutual interaction."
