Artificial intelligence has experienced major developments in recent years and represents an emerging technology that will revolutionize the ways in which human beings live. This technology is already being introduced in the field of higher education, although many teachers are unaware of its scope and, above all, of what it consists of. Therefore, the purpose of this paper was to analyse the scientific production on artificial intelligence in higher education indexed in Web of Science and Scopus databases during 2007–2017. A bespoke methodology of bibliometric studies was used in the most relevant databases in social science. The sample was composed of 132 papers in total. From the results obtained, it was observed that there is a worldwide interest in the topic and that the literature on this subject is just at an incipient stage. We conclude that, although artificial intelligence is a reality, the scientific production about its application in higher education has not been consolidated.

Problematic Internet use (PIU) has begun to be linked to the development of certain eating disorders. This uncontrolled use of the Internet is mainly found in the student population. The purposes of this paper were to determine PIU-related eating disorders in students from a systematic review of the literature and to analyze the incidence of PIU in eating disorders through a meta-analysis of the literature. We used two electronic databases (Web of Science and Scopus) from inception to June 2019. The systematic literature review was based on fixed inclusion and exclusion criteria. A total of 12 studies were identified (systematic review) and 10 studies for meta-analysis, which included 16,520 students. Different eating disorders were associated with PIU: anorexia nervosa, bulimia nervosa, binge-eating disorder, food preoccupation, loss of control eating, and dieting. Furthermore, meta-analysis confirmed that PIU is a predictor of eating disorders in students. The groups of students with PIU presented a higher rate in the presence of eating disorders, these differences being significant. Finally, this study showed empirical evidence on the link between PIU and eating disorders. The need for prevention in childhood and adolescence is highlighted.

Currently, the e-learning method, due to the period of confinement that is occurring due to COVID-19, has increased its use and application in the teaching and learning processes. The main objective of this research is to identify the effectiveness of the e-learning method in the teaching of mathematics with adults who are in high school, in contrast to the traditional expository method. The study developed is quantitative, descriptive and correlational. The research design is quasi-experimental, with a control group and an experimental group. The results show that the use of the e-learning method has a positive influence on motivation, autonomy, participation, mathematical concepts, results and grades. It can be concluded that the e-learning method leads to improvement in adult students who are studying the mathematical subject in the educational stage of high school, provided that it is compared with the expository method. Therefore, this method is considered effective for its implementation in adults.

Good teaching practices are developed in order to improve student learning. With technological and social development, educational practices increasingly demand the use of technology, so having good teaching practices with Information and Communication Technologies (ICT) is essential. At the same time, the Sustainable Development Agenda of the United Nations for the year 2030 is setting the principles of sustainable action for today’s society. In this context, the following objectives were proposed: to identify the good teaching practices with ICT that are being developed in Spanish higher education and to establish the relationship between good teaching practices with ICT and the Sustainable Development Goals (SDG). For this purpose, the method of systematic review of the literature based on the PRISMA protocol was used. A total of 27 documents published in the period 2008–2019 on good teaching practices with ICT in Spanish higher education were analyzed. Among the results, the emerging trend of good practices with ICT, the use of a Virtual Learning Environment (VLE) as the main technology in good practices, and the majority of good practices in the development of SDG #4 (Quality Education) are highlighted. Finally, it is a challenge for teachers to include all these aspects in their classroom teaching.

The technological development of recent decades has had an impact on the lifestyle of adults. As a result, it has been necessary for citizens to adapt and learn how to use technological resources, an essential requirement to foster employability. This requirement acquires a special nuance within Permanent Education, which mainly involves adults who would like to cover some training need. The aims of this study were to analyze the digital competence of Permanent Education teachers, and to determine the factors that have an impact on its development. Therefore, a quantitative methodology has been used, whereby a sample of Permanent Education teachers in the region of Andalusia, Spain, were asked to complete a questionnaire on digital competence (n = 140). The results confirmed the low digital competence of teachers, and how some factors such as age, kind of centre, prior training on ICT, degree, teaching experience and professional category affect the development of digital competence. The last part of the study discussed the potential explanations for the study findings and suggestions for future research.
