To test the effectiveness of electronic educational resources, a study was conducted in which the training of cadets of the experimental group was carried out with the use of the mentioned electronic educational resources, accessed by connecting to an interactive electronic environment of the departmental network of the National Academy of the State Border Guard Service of Ukraine. The results of the study show that the average values of cognitive and operational criteria in the experimental group were higher than in the control group. The results of calculations by the Pearson chi-square criterion confirmed the reliability of the obtained results. The materials presented in the article testify the effectiveness and expediency of using the proposed electronic textbooks and manuals for training future officers to use information and telecommunication systems of border guard units.
