Lexicon Evaluation of Preschool Children

The diploma thesis Lexicon Evaluation of Preschool Children is divided into a theoretical and a practical part. The theoretical part of this work on speech therapy describes within four chapters the Czech vocabulary, psychological development of children up to the school maturity, speech development also up to the school maturity and finally presents diagnostic materials used in the Czech Republic for school maturity diagnostics and diagnostics of the lexical-semantic speech level. The practical part includes a quantitative research performed on children respondents in preschool classes in maternity schools. The main goal of this speech-therapy research was the modernization and verification of a testing set aimed at active vocabulary. The main reason was the fact that there is a lack of any adequate material for testing vocabulary in the Czech Republic. The new testing set could be also used as a subtest for school maturity diagnostics. The research conclusions were compared with the real situation of the tested children as referred by their teachers. As a part of the practical part there is the establishment of the research aims and hypotheses, and subsequently the research description, verification of the established hypotheses and definition of research conclusions.
