摘要:Effectivity and quality of mathematical education at secondary school is always very actual didactic topic. One way how to increase them is using unconvencional experimentally inductive methods. There are described the methods as well as process and results of research conected with this problem there. The aim of the research was to check possibilities of using of modern unconvencional methods for more effective mathematical education at secondary school. The inductive methods are compared with the traditional ones when students get completed knowledge without any derivation or proof. Using Students t-test and F-test were verified two hypotheses. The first hypothesis that the experimentally inductive approach and methods in mathematical education at secondary school are more effective and interesting for students than the traditional methods was validated. The second hypothesis which supposed longer persistence of knowledge obtained by the inductive methods was not validated.
