Vyresniojo ikimokyklinio ir jaunesniojo mokyklinio amžiaus vaikų serijavimo ypatumai ir jo vystymosi pokyčiai
LTStraipsnyje teoriškai ir eksperimentiškai tyrinėjama viena iš pagrindinių J. Piaget aprašytų loginių operacijų - serijavimas. Teoriškai išanalizuotos serijavimo vystymosi pakopos. Atliktas pusės metų trukmės eksperimentinis tyrimas, kurio metu įvertinti vyresniojo ikimokyklinio ir jaunesniojo mokyklinio amžiaus (tiriamųjų amžius 5,7-11,6 m.) vaikų serijavimo operacinių lygių ypatumai ir jo vystymosi pokyčiai.
ENArticle presents the generalisation of literature in the field of J. Piaget and other scientists researches in development of profound processes of seriation ability. The aim of the practical investigation was to analyze the seriation ability in 6-12 year old children. Some characteristics of seriational ability are established: the level of operational seriation depends on children age; the development of operational seriation is inconsistent; there are no statistically significant differences between girls and boys groups in seriation ability. Very few children have completed the development of seriation. Only 8% (first investigation) to 9,6% (second investigation) children got in to the highest-forth level of operational seriation. Some children improved their seriational ability after half a year (30,5%), but there are such children, whose level of seriation is lower in second session, in comparison with first session. Children, whose index of operational seriation become worse in second session, are not able yet to coordinate all seriation actions in to coherent stabile system.
