The table shows that the value of Asymp. Sig is 0,989. This value indicates that before the research, there was not a statistically significant difference between the achievements of the pupils in the control group and the achievements of the pupils in the experimental group. There is a statistically significant difference if Asymp.Sig< 0, 05. After the realization of the topic “Functions of Proportionality”, pupils from both groups (the control one and the experimental one) were tested with the same knowledge test. The difference in the testing was that the pupils of the control group took their test on a sheet of paper, and the pupils of the experimental group took their test both on a sheet of paper and on the computer. In order to determine whether the achievements of the pupils in the control group and experimental group depended on the way the math classes were given, the following hypotheses were: 0H : There is not a statistically significant difference between the achievements of the pupils who attend math classes with ICT application and the achievements of the pupils who attend the math classes in which the classic verbal-textual method is used. 1H : There is a statistically significant difference between the achievements of the pupils who attend math classes with ICT application and the achievements of the pupils who attend the math classes in which the classic verbal-textual method is used. To test these hypotheses we used the Pupil’s t-test for repeated measurements. The knowledge test was repeated in both, the control one and the experimental one. In the control group the unit was taught in a traditional way and in the experimental group with ICT application.
