In response to emerging research diversity, ICCE2014 will be a meta-conference, comprising of seven co-located theme-based conferences. This is the Call for Papers for the theme-based conference, C4: Classroom, Ubiquitous and Mobile Technologies Enhanced Learning (CUMTEL). All the accepted papers will be published in proceedings which will be indexed by Elsevier Bibliographic Databases (e.g., Scopus, Engineering Village and others). Authors of accepted distinguished full papers will be invited to submit extended versions of the papers for consideration of publication Research and Practice in Technology Enhanced Learning (RPTEL), the official academic journal of the Asia Pacific Society for Computers in Education. Advocated by educators and researchers, the aim of ONE-TO-ONE technology enhanced learning (where each student has at least one portable computing device for learning) is realized with the increasing adoption of mobile, connected, and personal computing devices in everyday life and work. This approach has the potential to stimulate rapid changes in the field of education. Together with pervasively embedded cheap and tiny computing chips and sensors in our living and learning environment ubiquitously, such technologies not only make tangible objects smart, but also provide us with novel ways to interact with our environment, both individually and collaboratively. Thus, these new technologies can be considered as driving forces that seamlessly connect formal learning settings, such as classrooms or lecture halls in schools or universities, and informal learning settings, such as outdoor environments or museums, constructing various new learning scenarios. Therefore, CUMTEL has opened up a new line of educational research that highlights both pedagogical and technological innovation in order to support and enhance contemporary pedagogical design for individual and collaborative learning with mobile, contextualized, and ubiquitous technologies. This theme-based conference will present both the results of current research efforts in this field and future challenges in terms of pedagogy and technologies, as well as socio-technological aspects such as scalability, policies, privacy and security, teachers’ professional development, and so on.
