The effects of using an advanced and vanguard tool based on concept
mapping, empowers learning even in presence of special needs like
dyslexia

Dyslexia affects millions of kids and adults all over the world. This
dysfunction isn't due to intellective limitations: the dyslexic is
frequently intelligent and also gifted, creative and intuitive.
Some famous names of dyslexic people or that have some other
learning problems: Harry Belafonte,
el Gen. George Patton, Michael Faraday, John Lennon, Albert Einstein,
Pablo Picasso, Lewis Carroll, Hans Christian Andersen, and some many
others
… But this people have not succeeded "in spite of" dyslexia; another
view could be that they succeeded because they had dyslexia.
Creativity is also proverbial in DDA's.

Though there are not two dyslexics alike, the more frequent symptoms
are:
|
the difficulty of learning
from essentially linguistic means, for reasons neither obvious
or visible; |
|
the difficulty of sequential
processing of information, as happens with written or spoken
language.
|
|
|
The dyslexic principally has the capacity of global processing, and
learns by other cognitive strategies:
the dyslexic thinks in non-verbal and
structural
mode.
Dyslexics are visual,
multi-dimensional thinkers (using all senses).
Because they tend to
think in pictures, it is sometimes hard for them to understand
letters, numbers, symbols and written words.
As a result, lessons,
conferences and the learning environment are difficult for them.
This is not because something is wrong with them, it is because
lessons are not taught in the way they think and, besides, the way
lessons are usually taught do not account for the way human memory
is naturally organized not only for dyslexics, but for all human
beings.
Often it is thought
that dyslexia is simply a problem of reversal or omission of letters
or words, but it is not limited to these problems (a very frequent
misconception).
Dyslexia is a modality
of thinking that tends to compensate the difficulty of language sequential
processing.
This is why in any learning technology for dyslexics some specific
factors must be involved:
-
Strong interaction
(interaction is an important element because it raises
motivation and attention, for instance automatic
assessment questions, paths and some other functions in
Knowledge Master)
-
Optimal use of voice
(even though voice is absolutely necessary because it
helps avoiding "reading" [the "problem"], reading aloud text
does not contribute to learning, because it still makes
integration of contents difficult). Optimal use of voice
is achieved with reading of concepts, execution of paths, and
listening to automatic assessment questions with its answers,
all of them discrete, brief elements, easy and fast to
integrate.
-
Graphical interface (the
map graphical interface contributes to overthrow the first
limitation to learning: text.)

Dyslexics don’t all develop the same gifts, but they do have certain mental functions in common:
|
They have an
exceptional capacity to visually handle cognitive structures (a primary ability).
|
|
They use global
representations. They are able to integrate much information and
many variables. |
|
They are
instinctively oriented to learning through operations (doing,
looking at how things work). |
|
Their tendency to
visual thinking and concrete experimentation renders them
particularly intuitive with a strong and insight.
|

Dyslexia is frequently evidenced differently in different countries
(or different linguistic groups), related with the
regularity/irregularity of the orthographic representation of
phonemes, it is, the correspondence between phonemes and graphemes.
Dyslexia has a neuropsychological base: some processes of perceptive
discrimination and memory, necessary to its support, are in deficit.
The non-diagnosed dyslexic student is
usually considered laggard, slow, distracted, and these
characteristics are a result of the evaluation of his/her poor school
performance, and hence this student is compelled to do more, to
dedicate more, and to some extent, his/her learning ability is underestimated
.
The result of this viewpoint is that
the student loses self esteem.

The truth is that dyslexics learn in some other way, not from text neither from speech.
With programs that
enable "listening to text", the effort is aimed at the compensation
of the evident reading disability in dyslexics.
It is true that the
contemporary use of the auditive channel somehow improves the
perception of the written message, but there remains a problem (the
main problem from the learning point of view), that this approach
does not solve: decoding contents is even more difficult to the
dyslexic.
Text vocalization, therefore, is not a real solution, but just a palliative.
The person that reads
"without problems", must read and reflect several times, accessing
semantic memory (the permanent or "long term memory", that keeps
previous knowledge) to integrate the new information, e.g. "learning";
to the dyslexic this integration task is troublesome, even with the
"listened" to reading, because his/her working memory functions with
less efficacy when it must operate on verbal representations, that
require sequential processing: the real problem is text / speech
processing.
Sequential
processing is only one of the modes with which the mind decodes
information. While traditional learning modes are mainly founded
on this approach, Knowledge Master maps favor using the global
and synthetic modality, specially active in dyslexics.

|
The Knowledge Master approach to concept maps (or semantic networks / knowledge bases) as a resource to power the learning abilities and results of the dyslexic student.
Dyslexia, as said before, is also
the
difficulty to process verbal sequences, such as speech and the
correspondent textual equivalent. The Knowledge Master approach to
concept mapping has some features that enhances learning in
dyslexics:
|
maps have a graphical interface and
the dyslexic thinks better in graphic mode; |
|
the format in which information is
presented is nearer to the organization of ideas and concepts in
the mind; |
|
maps are not "read" sequentially,
because these are direct access structures, and therefore there's
no need of sequential (reading or access) processing; |
|
semantic (or logic) units are
directly recognizable and analyzable; |
|
search and analysis tools in KM facilitate accessing contents, at a
cognitive level; |
|
the Knowledge Master "active voice"
describes the cognitive structure in its essence of concepts and
relations, organized in simple propositions. This reduces to the
minimum the need for sequential processing; |
|
the association between the
cognitive message logic (knowledge), the graphic representation
and the synchronic use of the auditive channel (i.e. the synergy
between logic, cognition, multimodality and multimedia), beside
transcending the possibility of the traditional exposure to text,
appeals to the strongest capacities of dyslexics, their visual
capacities, and improves their perceptive abilities in general; |
|
using the main principles of
cognitive psychology, such as categorization and relevance
in Knowledge Master (it is
an automatic recognition function), the effort to learn is reduced
to the minimum; |
|
semantic paths (characteristic in
Knowledge Master) that represent
higher order concepts, take advantage of graphic animation and
vocalization as well; |
|
question -> answer sessions (an
automatic conversion of the map cognitive structure) enables the
simplified interaction with contents to learn (and the full dialog
is vocalized); these sessions become unintentional and effective
drilling sessions about contents to be learned. |
|
This being a technology designed to
power learning in general, without distinction of age or personal
abilities, the dyslexic is not isolated or differentiated from
his/her schoolmates: this technology can also become a school
social integration tool, without evidencing "diversity".
