Using a Praxeology Approach to the Rational Choice of Specialized Software in the Preparation of the Computer Science Teacher

From the positions of Praxeology, the aspects of the forming of the future teachers' abilities to choose software that turns out to be the most rational for the solving of the professional task are considered in the article (on the example of computer science teachers' preparation to use dynamic mathematics software (DMS).

The methodology of organization of such experimental studies on the base of Sumy State Pedagogical University (Ukraine) is described. The results of the statistical analysis of data are given on the basis of non-parametric sign test for dependent sample. It is educed that taking into account such approach provides the positive dynamics of the level of future informatics teachers' preparation at the significance level of 0.05.
