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 Student′s 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.
