Abstract
This study investigates fundamental concepts in information theory within the context of integrating educational technology. The study employed modelling, sociological surveys and statistical analysis. The researchers devised an educational framework for secondary school students aimed at understanding key principles of information theory and applying a probabilistic approach to determine information volume. The training scheme emphasizes competencies in algorithmic and software solutions and imparts knowledge on data encryption. Students’ motivation was assessed in two groups: one studied the subject using digital educational programmes, and the other without them. The analysis of students’ attitudes demonstrated strong commitment to using technology. The study found a statistically significant difference between the usefulness and ease of use of the programmes, with usefulness prevailing. The study highlights the role of digital technologies in enhancing cognitive activity and improving learning.
