Comparative Change of Knowledge and Skills in Chemistry of the Students Participating or not Participating in Olimpic Competitions

Summary/Abstract: The article anlyses the situation how the additional extra curricular studies of chemistry influense knowledge and skills of chemistry. The coparative analysis of knowledge and skills of the students participating in the olimpic competions and not participating was performed. While comparing evaluation marks of tests of ninegraders (of the ones participating in the olimpic competition and not participating), it was concluded that ninegrades of both categories understand the teaching material of chemistry equally well. But the ones who participate in the olimpic competitions more successfully apply the knowledge in practice, analyze chemical phenomena. Elevengraders of both categories performed the tasks, which include the levels of knowledge and synthesis, almost equaelly (p > 0,05). But the tasks, which include such cognition levels as understanding, application, analysis, eveluation, were performed better by the students participating in the olimpic competitions (p < 0,05). Tengraders and twelvegraders participating in the olimpic competiotions all tasks, which include all six levels of cognition, performed better then the ones not participating in the olimpic competitions (p < 0,05). It was identified that additional extra curricular studies of chemistry influensed the knowledge and skills of chemistry of boys more then of girls. The conclusion was made that more attention should be paid to extra curricular studies of chemistry to the students living in smaller settlements. They should be provided with modernised teaching and learning conditions, in-service training of teachers should be differenciated. The analysis of the research showed that the teaching of chemistry less academic but more in line with students' intrests and demands influenced better knowledge and skills of the students participating in the olimpic competitions. They were able to better perform different operations of thinking (generalization, comparison, systematization).
