Adaptive behavior and achievements in mathematics education in children with mild intellectual disabilities

Abstract

Mathematical abilities are a constellation of different skills and abilities, such as general intellectual abilities, executive functions, verbal and spatial abilities. With the aim of determining the relation between adaptive behavior and mathematical achievements in children with mild intellectual disabilities, a sample was selected consisting of 90 children of both genders, aged between 10 and 13.11, IQ 50-70. Information on adaptive skills was acquired from standardized interviews with special education teachers, by applying the 1st part of AAMR Scale of adaptive functioning. One-way analysis of variance, Scheffe Post Hoc Tests of arithmetic mean differences, and x2 test were used in statistical data processing. It was concluded that the following domains of adaptive behavior represent significant achievement factors in mathematics education in children with mild intellectual disabilities: Speech and Language Development, Numbers and Time, Prevocational/Vocational Skills, Self-determination and Responsibility.

Matematičke sposobnosti su izraz konstelacije različitih sposobnosti i veština, kao što su opšte intelektualne sposobnosti, egzekutivne funkcije, verbalne i specijalne sposobnosti. U cilju utvrđivanja odnosa između adaptivnog ponašanja i postignuća u oblasti nastave matematike kod dece sa lakom intelektualnom ometenošću (LIO) odabran je uzorak od 90-oro dece čiji je IQ 50-70, oba pola, uzrasta 10-13.11 godina. Podaci o adaptivnim veštinama dobijeni su na osnovu standardizovanog intervjua s defektolozima, primenom prvog dela AAMR Skale adaptivnog funkcionisanja. U statističkoj obradi podataka korišćeni su jednofaktorska analiza varijanse, Scheffe post hoc test značajnosti razlika aritmetičkih sredina i x2 test. Utvrđeno je da su domeni adaptivnog ponašanja: Govorno-jezički razvoj, Brojevi i vreme, Preprofesionalne/ profesionalne aktivnosti, Samousmeravanje i Odgovornost, kod dece sa LIO značajni činioci postignuća u nastavi matematike.
