Abstract

Based on the theoretical analysis of scientific, technical and methodological literature, study and summarizing the experience of didactic reduction methods developing, using the methods of statistics, a method of vertical didactic reduction of the learning content of the environmental soil monitoring has been developed. The sufficiency of the content is substantiated, verified and confirmed using the methods of statistics. The implementation of the method leads to a decrease in time for measurements, calculations, and analysis when obtaining an approximate result with statistically small errors. It leads to the maximization of information about the results obtained under conditions of limited study time, as well as under conditions of limited time for its implementation into future professional activities. The vertical reduction method comprises the following steps: selection of research objects and identification of partial indicators for soil evaluation; data collection for analysis; standardization of partial indicators and calculation the integral indicator for soil evaluation; identification of partial indicators that are the most important in their influence on the integral indicator on the basis of multiple regression; clustering research objects in order to determine their excellent characteristics and typical cluster representatives; formation of conclusions and implementation of the vertical reduction method of the learning content of the environmental soil monitoring. The results are adequate which is evidenced by the high values of the coefficient of determination, R2 = 0,967, the adjusted coefficient of determination, Adj. R2 = 0,961, and by the low value of the standard error estimator, Std. Error of estimate = 0.021. The method forms a toolkit for its application in relation to other topics of the environmental monitoring learning.
