The University of Silesia in Katowice, through the implementation of another higher education student and staff mobility project, continued its activities to stimulate academic educational exchange. The aim of these activities was to further increase the level of internationalisation of the university, with regard to both the educational and research aspects of the university's activities. In the first case, the expected direct impact of the project was: - Increase in the number of students realising part of their studies or doing a traineeship abroad at partner universities, - Increase in the number of foreign students realising part of their studies at the university within the international educational exchange, - Increase in the number of employees of the university carrying out teaching activities at partner universities abroad, - Increase in the number of employees of the university increasing their professional competence by carrying out trainings abroad, - Increase in the number of employees of foreign partner universities visiting the University of Silesia in Katowice in order to teach or receive training, - Intensification of the exchange of good, tested practices, - Improvement of the didactic offer of the university, - Development of the European campus created thanks to the European University within the Transform4Europe consortium under the leadership of the consortium and project leader – Universität des Saarlandes and in collaboration with eight universities: Universidad de Alicante, Eesti Kunstiakadeemia, Universidade Católica Portuguesa, Univerza na Primorskem, Université Jean Monnet Saint-Étienne, Софийски Университет ‘Св. Климент Охридски’, Università degli Studi di Trieste, Vytauto Didžiojo Universitetas and with an associated partner of the consortium: Маріупольський Державний Університет. The impact of the participation of the university in successive higher education student and staff mobility projects under the Erasmus and Erasmus+ programmes is clearly direct, and the results of these projects are cumulative in subsequent years. Outgoing and incoming mobilities under these projects constitute the main part of the educational exchange of students and staff. Their implementation is therefore crucial for the effective achievement of the objectives of the University of Silesia's development strategy. In the case of the scientific and research sphere of activity of the University of Silesia, the expected impact was mainly of an indirect nature, resulting from the increased presence of foreign students and employees, the development of a network of international links and the intensification of international cooperation. Nevertheless, the expected direct impact, related to the possibility for employees of the University of Silesia to receive training abroad, was also important. Training in key linguistic, teaching and digital competences was assumed to be of particular importance, but the expected positive impact of project implementation and individual training in the field of science and research was also taken into account, particularly with regard to activities combining aspects of teaching, education and research. It was also assumed that there would be an increase in the participation of administrative and technical staff in training visits, in connection with the continuous modernisation and improvement of the university's operation and the process of its full adaptation to completely open international activities. The University of Silesia planned to implement a maximum number of mobilities as part of the project, while respecting formal requirements and quality criteria. At the same time, it was assumed that further efforts would be made to achieve full participation of all potential participants and individual beneficiaries in the project. Participation in international educational exchange within the Erasmus+ programme was determined solely by meeting formal, linguistic (taking into account the type of mobility, the project also assumed improvement of language competences of individual participants) and content-related requirements. The University of Silesia's goal is to ensure the permanent absence of any factors preventing or hindering the participation in the Erasmus+ programme for its potential individual beneficiaries, both with regard to outgoing and incoming mobility. Particular importance in the project was therefore attached to the implementation of training mobility and the promotion of short-term mixed mobility of students and doctoral students (in the case of doctoral students with the possible inclusion of short-term purely physical mobility) and the intensification of virtual activities. As in the case of the implementation of previous projects, the university offered the greatest possible support to both outgoing and incoming individual mobility participants with special health needs or otherwise limited access to participation in the exchange.
