Information has become a global inexhaustible resource for mankind, which has entered a new era in the development of civilisation. Today it is important to improve the quality of education by introducing computer technologies in chemistry classes. The purpose of the study was to develop and present the methodological foundations of the development and implementation of computer technologies in the game teaching of chemistry to improve the teaching methods. To achieve this goal, the corresponding tasks were identified, as well as methods for their solution: the analysis and comparative analysis, modelling. Results of the study: the positive and negative factors of the use of modern computer technologies in chemistry classes were identified; the principles of selecting the content of the material using information and communication technologies in teaching were characterised; the methodical foundations of the application and use of information and communication technologies when teaching chemistry were considered. It was concluded that the use of a computer in the educational process contributes to the improvement of teaching methods more than any other technical means at the teacher's disposal. The introduction of information technologies into the educational process significantly changes and ultimately increases the effectiveness of teaching. The practical significance of the study is conditioned by the fact that the methodical foundations of the use of information technologies in chemistry class presented in the paper can be applied in schools and other educational institutions.
