Welcome to this very international issue of Research in Learning Technology in which we present research that has been undertaken in UK, Chile, Finland, Germany, Portugal and USA. The articles on the use of technology span a range of effective teaching practices, showcase strategies for successful learning and propose ideas for future mechanisms to better engage students in their educational experiences. For me, one question running through this issue is: how is technology helping us to deliver more student-centred education?The first article by Pedro et al. (2014) investigates the use of a recommender system across all educational sectors in Portugal. A recommender system recognises us when we return to sites previously visited such as booksellers and music download sites. They are responsive to our personal interests and offer recommendations that are aligned to our previous online transactions. Use of recommender systems in educational contexts is less common. This article explores an early implementation of a recommender system in four institutions from elementary to university level. Preliminary results highlight that the younger the learner, the more responsive they are to recommendations.Next, a study by Kear, Chetwynd and Jefferis (2014) on social presence explores how effective personal profile pages can be in reducing student isolation. Two studies conducted at the Open University UK approximately 5 years apart illustrate that students' use of personal profile pages can be of value in developing a sense of personal connection. The extent to which students considered personal profile pages as helpful is measured across the passage of time and the change in technologies.Another strategy for engaging students that we are increasingly seeing is the use of social media tools within the online teaching and learning dynamic. Blaschke (2014) investigates whether integration of a suite of social media tools into the learning design can aid students in developing their metacognitive skills and become more work-ready. She reports a case study of 14 cohorts of postgraduate students undertaking foundations studies of distance education and e-learning in Germany.A study from the USA by Butz, Stupnisky and Pekrun (2015) compares online and on-campus students' emotions. This excellent piece of research greatly raises our awareness of the anger, anxiety and helplessness that students may feel when additional technology is introduced into their learning environment. Students' positive experiences of control, value and perceived success are also explored in this article. The authors recommend that we, as educators, need to understand the differences between the emotional supports that are required for learners depending on their study mode.
