Representación de problemas matemáticos asociados al uso del algoritmo de signación en población sorda

Abstract

Objective.
The purpose of this research was to describe the change in performance (achievement
and types
of representation employed) of students attending a school for deaf peo
ple in the city of Cali, after receiving
instructions in the use of the assignment algorithm proposed by Nun
es and Moreno (1998b).
Method.
For this
purpose, a descriptive study was carried out, in which
a pre-test and post-test formula were used, as well as
a descriptive comparison with control group. Eight students took part,
to form two groups of four members
each. As an instrument of evaluation, a battery of arithmetical problems was ap
plied in arabic format, and in
Colombian sign language (CSL), in the pre as well as the post test. The
intervention consisted of five sessions
in which an explanation was given to students on the use of the al
gorithm for solving problems of addition.
Results.
A descriptive statistical analysis was carried out for categorized variables, whi
ch showed differences
in percentages of achievement, ways of problem representation and the use of st
rategies in the post test group.
Conclusion.
The conclusion drawn from the results was that an educational strategy des
igned for deaf people
could help to improve learning of basic mathematical concepts.
