Introduction The SELI project is an innovative, international action aimed at supporting learning and inclusion processes using the potential of the tools of the information society. The project was implemented between 2019 and 2020 by representatives of universities from Latin America, Europe, and the Caribbean (Tomczyk & Oyelere, 2019; Oyelere & Tomczyk, 2020; Arteaga, Tomczyk, Barros, Sunday Oyelere, 2020). The activities of the project in each country took a synchronous course, starting from the development of a common theoretical framework, diagnosis of digital literacy among the recipients of the project, construction of the platform, and the preparation of unique e-learning courses. The Polish team was represented in the project by researchers and academic teachers from the largest pedagogical university in the country. The researchers from the Pedagogical University of Crakov were responsible in particular for developing diagnostic tools measuring the level of digital competence, attitudes towards media, and experience with e-learning. Comparative research was conducted in all of the countries involved in the SELI project (Oyelere & Tomczyk, 2020). The activities aimed to show the multifaceted nature of the conditions that relate to learning and teaching, mediated by new digital technologies. Each of the activities adopted a separate block of activities, classified as a Work Package (WP). The diagnostic part of the project was WP2. 1 Pedagogical University of Cracow: Corresponding Author: Lukasz Tomczyk lukasz.tomczyk@up.krakow.pl
