Molecular models in teaching organic chemistry at the grammar school
 Marek, Milan ; Beneš, Pavel (referee) ; Hlavatý, Josef (referee)
TITLE: Molecular models in teaching organic chemistry at the Grammar School AUTHOR: Milan Marek DEPARTMENT: Department of Chemistry and Chemical Education ABSTRACT: The thesis is focused on the use of molecular models in teaching organic chemistry at the Grammar School. Models are used for a presentation of the structure of organic compounds and especially their chemical characteristics. The research includes the construction of models (based on quantum-chemical methods), selected organic compounds from the category hydrocarbons, halogenated hydrocarbon and oxytgented derivates of hydrocarbons and other types of compounds. Along with the relevant models, the tasks focusing on the structure and reactivity of compounds are processed. The research examined the influence of the use of models for a success solving task of students from 3rd year of Grammar School. Tasks are related to the distribution of electron density in the molecule, delocalization of electrons substitution effect of typology reaction etc. 223 students participated in this research. The research results have shown the increase of the success of solving the tasks of those students who could use molecular models, in some cases the increase of 26% has been shown. The positive effect of the models for solving of problems is individual and it...
