INFORMATION CAPACITY OF GRADE INDEX IN COMPLEX EVALUATION OF ADAPTATION OF JUNIOR SCHOOLCHILDREN TO DIFFERENT FORMS OF TEACHING TECHNOLOGIES
Analysis of the results of longitudinal studies of the indices of physical development had shown that in the group of children with elevated levels of total school anxiety «growth in length» prevails (after I.M. Vorontsov). The growth rate in anxious children increases in training periods of academic year and is lowered during school holidays (in contrast to their classmates with standard level of anxiety). School stress, which provokes the increased level of anxiety, causes the disturbance of the balance of the autonomic (vegetative) regulation and negatively affects the state of cardio vascular system as well as leads to increased morbidity in anxious students. Most of all it is expressed in those who are taught by Elkonin-Davydov's method of developing training. Implementation of Grade Index had allowed to identify the dynamics of changes in physical development during the first academic year and its normalization by the end of systematic training in an elementary school (after the first three years of schooling), which indicates the appearance of adaptation in junior schoolchildren to the conditions of traditional teaching and extension of negative effects of elevated levels of anxiety under the conditions of developing training.
