Social Media tools are seen by many authors as powerful drivers of change for teaching and learning practices, in terms of openness, interactivity and sociability. However, extensive surveys about actual use that are carried out with large samples at a national level are rare. This study reports the results of a survey addressed to the Italian academic staff, with the aim of identifying the uses of Social Media in the field of university teaching practices. The response rate was 10.5%, corresponding to 6139. The respondents were asked to identify frequency of use, motivations, teaching practices and obstacles related to the use of a number of tools: generic social network sites (Twitter, Facebook), professional and academic networking services (LinkedIn, ResearchGate and Academia.edu ), tools to write and comment (blogs, wikis) and to archive and retrieve content material for lectures and group work (podcasts, YouTube and Vimeo, SlideShare). Analyses of data tested which socio-demographic variables mostly affected frequency of use, and the relationships between motivations, ways of use, barriers to use and the scientific discipline. The results show that Social Media use is still rather limited and restricted and that academics are not much inclined to integrate these devices into their practices for several reasons, such as cultural resistance, pedagogical issues or institutional constraints. However, there are differences among academics in the ways they use Social Media or perceive them, mostly depending on the scientific discipline of teaching. Overall, the results emphasise ambivalent attitudes towards the benefits and challenges of Social Media in the context of higher education with obstacles prevailing over advantages.

Abstract: Over the last decades, the issue of digital divide has received particular attention from international bodies and researchers in Western countries. One of the main reasons for this growing interest is related to the implications that digital inequalities have for social development and particularly for education. Despite the relevance of the issue, there are still few studies on the digital divide in China and even less on Chinese K-12 schools'' students. This paper aims at exploring the digital divide issues among Chinese children from an educational and social perspective. Four schools were selected, involving 658 students aged 10–14. Nine hypotheses on Internet inequality indicators (DiMaggio & Hargittai, 2001) and their possible outcomes were tested. The study found that: (1) students'' Internet access at home is better than that at school; (2) compared with parents, teachers have more positive influence on students'' Internet behaviour; (3) students from rural or migrant schools score lower on all the Internet inequality indicators (digital access, autonomy of use, social support, Internet use and self-efficacy) and are therefore more disadvantaged in Internet usage status than their urban peers; (4) there are no significant gender differences; (5) the more education parents have received, the better the conditions of their children according to the listed Internet inequality indicators; (6) the dimensions of the Internet inequality indicators (technical apparatus, autonomy of use, availability of social support, variation of use) are significantly correlated to students'' Internet self-efficacy; (7) there is high correlation between students'' Internet self-efficacy and their exploring behaviours of Internet use and their academic performance. Overall, these results are consistent with data from OECD countries and confirm that the digital divide represents a big social challenge, revealing that schools still have to develop effective strategies to balance social and learning opportunities among students.

Digital competences amongst the younger generations and the role of schools faced with the spread of new youth practices are topics of increasing interest. Some commentators state that, thanks to the intensive use of digital media, young people are developing significant competences that also correspond to important cognitive processes and new learning styles. However, other authors emphasize that there is no evidence about the positive impact of new technological practices on the development of significant cognitive abilities. In this paper we present a research study carried out in Italian schools on adolescents’ (aged 14–16) digital competence. On the basis of a preliminary theoretical model, a digital competence questionnaire was formulated and subsequently administered to a sample of secondary school students. The aim was to verify whether adolescents’ digital skills are limited to simple technical aspects or expand beyond them including a range of more significant knowledge and skills related to a conceptual understanding of technology, socio-relational knowledge and high-order cognitive skills. Like other studies, this research shows that when attention is shifted from strictly technical aspects to critical cognitive and socio-ethical dimensions involved in the use of technologies, students’ knowledge and competences result inadequate. The authors conclude that the optimistic portrayal of younger generations’ digital competences is poorly founded. Furthermore, it is pointed out that understanding students’ digital competence levels through fast assessment tools is a fundamental opportunity for schools to analyse deficiencies and prepare adequate intervention strategies.
