Starosta V. The Theoretical and Methodical Principles of Training of Schoolсhildren to Compose and to Solve the Tasks on Chemistry

In the dissertation there is scientifically proved theoretical and methodical principles of training of the schoolсhildren to make and to solve the tasks on chemistry, is developed the concept of application of the educational tasks on chemistry and pedagogical technology of its fulfilment. The advantages and disadvantages of application of the educational tasks on each of stages of development of the methods of chemistry are established With application of activity, model, system and structural approaches the analysis is made and there is offered structure of the educational tasks, their classification and list of the necessary requirements, there is determined structure of processes of the solution and composition of the chemical tasks. In research the shown ways of realization of the developed general approaches of training of schoolсhildren to make and to solve the tasks on chemistry on an example of concrete themes ("The Chemical formulas of substances", "The Equations of chemical reactions", "Preparation of solutions") are shown. There is developed and carried out checking pedagogical efficiency of the methods of training the schoolсhildren to make and to solve the tasks on chemistry with taking into consideration gnosiological, psychological and pedagogical, chemical (subject) aspects.
