Modern information and communication technologies have intensively reformed the teaching process in higher education, expanding new opportunities for learning and access to educational resources, compared to those used in traditional learning. Taking into account the specifics of the application of these technologies in different scientific disciplines, the aim of this paper is to analyse the impact of the teachers' scientific field on the effects of the application of these technologies in selected higher education institutions. The research included teachers from 10 faculties and three schools of applied studies, who provided answers to 20 survey questions. After the survey and statistically processed results, the attitude of teachers from different scientific fields to the effects of the implementation of these technologies in selected higher education institutions was analysed. In addition, the forms of application of ICT in the conditions during the Covid 19 pandemic were analysed. The obtained results indicate various effects, as well as certain shortcomings, in the implementation of these technologies in the analysed higher education institutions, provided by teachers that belong to various scientific fields.
