People's attitude towards digital devices is quite paradoxical. In some areas, they are considered absolutely irreplaceable. In other ones, they are seen as dangerous and must be avoided. Analogically, the school contexts reflect the same situation: media and ICTs, and in general, they are risky; therefore, on the one hand, digital devices are forbidden and their use is prohibited, and on the other hand, technology pervades almost all areas in society (Scherer, Siddiq & Tondeur, 2019) and the new generation of teachers faces considerable demands with respect to the use of new technologies in education (OECD, 2010). In other words, a generalized feeling considers technology as a danger for pupils' cognitive and social health but, at the same time, digital devices are around us and stay silently by us. The role of scholars and researchers is as follows: Studying deeply the digital phenomena and identifying their potentialities and limits in a scientific way. Instead, the role of teachers is more difficult because they have to face the challenges offered by the digital situations and balance their actions between a proper use of technologies in the educational settings, supporting the pupils' cognitive and social growth and understanding the parents' fears, worries and doubts. Teachers walk along the border between a scientific level (the studies related to ICTs' use) and a practical one (caring the relationships with pupils' families). Consequently, there is a further crucial role, located between the academic and the educational contexts, between universities and schools: the teacher educators. Teacher educators play a central and essential role in supporting the digital professional growth of future teachers. «Teacher educators can be considered important stakeholders who prepare and motivate a new generation of teachers for teaching in today's classrooms. They can also play a key role in enhancing preservice teachers' technologyenhanced educational practices. Consequently, preparing future teachers to integrate technology in their educational practice is a challenge that teacher educators are increasingly confronted with (Liu, 2016; Ping, Schellings, & Beijaard, 2018)» (Tondeur et al., 2019, p. ??). Therefore, the question becomes twofold. Former: Which are the main characteristics of teacher educators who can support and prepare trainee teachers for a valuable and effective use of technology at school? Latter: in what way, we should change the teacher education programmes to facilitate and promote this process? Regarding the first question, «Foulger et al. (2013) identified 12 Teacher Educator Technology Competencies (TETCs) and defined the knowledge, skills and attitudes teacher educators need in preparing preservice teachers for teaching within technology-enhanced learning environments. Some examples of the competency areas included: aligning content with pedagogical approaches and technologies, modeling the use of online and blended learning methods and strategies, guiding the ethical and responsible use of ...
