Professional training of computer science teachers through the system of staged continuing education

The aim of the study is to assess the effectiveness of staged continuing education in the formation of professional competencies of computer science teachers and its impact on adaptation to digital technologies. The research methods included questionnaire surveys of teachers with different work experience, a pedagogical experiment with division into control and experimental groups, analysis of learning outcomes, and statistical assessment of the impact of digital technologies on teaching. The results of the study showed that the staged education system significantly increases digital literacy (+38%), the integration of STEM methodologies (+34%), and the effectiveness of adaptive curricula (+29%). The best indicators were demonstrated by teachers with 5–8 years of experience, who were able to combine technological training with practical experience. The findings prove the effectiveness of the implementation of staged education for the development of technical and pedagogical competencies. The academic novelty is the developed integrated training model that combines adaptive programmes, digital platforms, and interactive methods. Further research prospects include a long-term analysis of the effectiveness of this model in training teachers of other subjects and expanding its capabilities by integrating artificial intelligence and virtual reality.
