The aim: to describe the dynamic changes in mental capacity during education in secondary school in the implementation of traditional and meritocratic educational program. Materials and methods. The study involved 56 secondary schoolchildren in the dynamics of learning, which were divided into 2 groups depending on the education system. The level of mental capacity was assessed using proofreading tests of V. Ya. Anfimov. Statistical data processing was performed using one-way analysis of variance and t-test in the software package IBM SPSS Statistics 20. Results. During the period of basic education, the level of influence of the type of educational program, type of subject and day of the week on the accuracy of the test performance increased, the amount of work increased by 16.2-16.7 % (p<0.01) and its accuracy decreased (p<0,05). Higher initial and post-load intensity of mental capacity was revealed in schoolchildren with meritocratic education (353.23±8.52 and 341.41±8.65 respectively), and with a traditional system - higher and stable accuracy (5.68-5.86 errors) and productivity of mental work (35.29-35.72 conventional units; p<0.01). The weekly efficiency curve was the opposite in terms of accuracy for 6th and 9th grade schoolchildren, and the identical in terms of volume. In meritocratic education, a higher level of intensity was registered in the mathematics lesson, and in the traditional educational program − accuracy against the background of negative dynamics of quantitative and complex indicators. Conclusions. Gender and age features of intensity, accuracy and productivity of mental work during basic education and the level of influence of factors of the educational process on them are established. The increase in the level of educational load was accompanied by an increase in the intensity and accuracy of mental work due to the adaptation of schoolchildren to the peculiarities of learning in secondary school and the stabilization of physiological processes. Comparison of weekly curves of mental capacity during training allowed to identify certain age trends in the formation of mental fatigue

The aim of this work is: to define the Conceptual model of medical provision of children in educational institutions in modern conditions. Materials and methods: analysis of data from a longitudinal study of children’s health; questionnaire of parents, teachers, heads of educational institutions on the volume of medical support for students; questioning students’ lifestyle and social determinants of health. Results: According to the study has determined the medical and social determinants which negative affect on health status of school age childrens; detected the most appropriate types of of school health services which based on the parents, medical and teachers opinion. The important also is monitoring of health status of children for develop of prevent measure for improove health status and forming of healthy lifestyle behavioral. Problematic issues to be addressed include: improving the legal framework on the competences and volumes of health care for pupils in educational institutions; material equipment; setting up a system for monitoring and analyzing the health status of students and educational groups, identifying health risk factors; establishing a continuous multimodal health-oriented system of student-oriented youth behavior. Conclusions: The health status of students and the level of health-oriented behavior, the reform of the medical sector require introduction of an effective system of medical support for students of organized groups, improving the system of preventive care for students, parents, which is presented in the Conceptual model.
