In the field of
multisensory education there are some things that remain the same. The
use of concrete objects and tactile if not gross motor strategies to anchor the
student in the learning is fundamental. These strategies address the
conceptual component as well as the attentional component of learning.
This is one reason that the multisensory strategies work well with language
based learning disabilities as well as related learning differences such as
ADD/ADHD. They do not interfere with traditional learners and in fact
enhance the learning for all students. They provide experiences which are
memorable through multiple learning channels.
Some things are open
to interpretation and adjustment. In the field of education, we sometimes
practice certain strategies which seem to become embedded in our practice
without question. They become "tradition" and though anecdotal
evidence may suggest efficacy, in fact they are not as efficient or as
effective as sometimes newer ideas. Take for example the "mad minute."
Though this may work for and encourage some students, the timed stressful
activity is a detriment to those who have processing or retrieval
difficulties. It is not that children do not need to practice math facts,
it is just that some methods of practice may not be the best for some children.
In fact, the impulse to quickly input/write an answer may fuel guessing and
reduce numeracy linkages. We have all seen the children who give an
answer an look immediately to the teacher for affirmation. Impulsive
students may lean toward shouting out any number as an answer because the
emphasis is on speed not accuracy. For many students, mathematical
thinking and as the NCTM says, "sense making," suffers when speed is
the goal.
When I formatted the
new math manual, in fact as I worked on it over the years, I jettisoned some
strategies that were based on a verbal approach to teaching facts. These
were the convoluted ones that asked students to use things like "sharing
doubles." As I reviewed the research on how the brain processes
mathematics, it became clear to me that using too many words and convoluted
stories to teach basic facts might be less useful than other visual and
numeracy based strategies being suggested by researchers such as Dehaene and Butterworth.
Over the years, the fMRI studies continued to suggest automatic recognition of
small quantities and building larger quantity awareness on the construction and
deconstruction of smaller quantities. Thus I jettisoned the traditional O-G
based strategies based on language and directionality.
As I have
updated the Multisensory Math Manual, the approach of this program has
become multifaceted. I am attempting to combine the best of what we have
from the traditional multisensory approach and the best of what we can learn
from the research in mathematics. Please review the addition and
subtraction chart in your manual. You will find no verbal strategies
which ask children to use working memory to traverse and link known facts to
others. Directionality is an issue for many alternative learners.
Back and forth addition and subtraction based on words is not easy for many of
our students. Instead, the student is encouraged to create the mental
imagery for the construction and deconstruction of quantity based on numeracy
patterns. With these he can continually draw on that mental imagery to solve
even more complex problems.
I have demonstrated
this in our video conferences with subtraction across place value. The
What Works Clearinghouse suggests that multiple representations be used for
concepts and strategies. This is one reason I use craft sticks,
Unifix cubes, base ten place value blocks, tally marks, dice etc. All of
these can be used to create mental imagery to support computation.
Repeated exposure to numeracy patterns can form the basis of more complex
calculations. Experience with these patterns will support memory and
extensions to larger more complex applications.
Many new text book
series are beginning to employ this idea of pattern recognition and numeracy in
developing number sense. Older strategies such as go to the ten and
counting on may still be used. They are based on skills and visual
imagery. The number line and concrete manipulatives are only tools in helping
students develop full numeracy awareness. We use all the tools available
to us but for those students who have language based differences we need to be
careful of using strategies based on too many words or associations of patterns
based on words. We need to remember that quantity does not have a single
color or shape. Over reliance on a single manipulative or rigid verbal
strategy actually may limit a student. Multiple representations are key
and memorable patterns based on visual stimuli and concrete constructions are
only the beginning.
We must ultimately
move students on to the abstract level and gently encourage memory and
retrieval through successful repeated practice which does not discourage or
lead to despair. The NCTM is emphasizing perseverance in problem
solving. It is emphasizing the great glow that students get when they
accomplish something challenging. Students should be challenged,
especially our gifted one. This is important but we need to ask ourselves
what exactly those challenges should be. Some of our gifted students are
gifted in ways that are not tested by a ticking clock or their ability to
remember stories about how to get to a target sum. They can be
defeated before they get to the mathematical starting gate which is applications.
To this end, the multisensory programs always emphasize teaching for success
and mastery. Thus, we seek the best tools and strategies available in an
ever changing educational landscape. The new NCTM publication, Principles to
Actions, emphasizes concept based instruction and seeks to summarize where we
are today. The executive summary is available on line.
