The rapid digitalization of higher education and the growing demands of the labor market have made foreign language proficiency essential for students of non-linguistic specialties. This study examines the effectiveness of integrating digital language resources into foreign language teaching at Polissia National University. The research employed a mixed-methods approach and was conducted over one academic semester with 78 students majoring in Economics, Law, Public Administration, and Accounting. Participants were divided into an experimental group and a control group. The experimental group used digital tools, including Quizlet, Google Classroom, interactive online dictionaries, and the AI-based assistant ChatGPT, while the control group followed traditional teaching methods. Data were collected through vocabulary and grammar tests, written assignments, oral presentations, questionnaires, and classroom observations. The findings indicate that students in the experimental group demonstrated significantly higher academic performance compared to the control group. Moreover, the use of digital resources enhanced students’ motivation, learning autonomy, communicative competence, and critical thinking skills. The results confirm that integrating learning management systems, interactive vocabulary platforms, and AI tools improves both language proficiency and student engagement. The study contributes to research on digital pedagogy and offers practical recommendations for foreign language teachers in non-linguistic higher education.
