These proceedings represent the work of researchers participating in the 9th European Conference on Games-Based Learning, which is being hosted this year by Nord-Trondelag University College, Steinkjer, Norway, on the 8-9 October 2015. The Conference has become a key platform for individuals to present their research findings, display their work in progress and discuss conceptual advances in many different areas and specialties within Games-Based Learning. It also offers the opportunity for like-minded individuals to meet, discuss and share knowledge. ECGBL continues to evolve and develop, and the wide range of papers and topics will ensure an interesting two-day conference. In addition to the main streams of the conference, there are mini tracks focusing on the areas of the design of multiplayer/collaborative serious games, applied Games and gamification, the teacher's role in game-based learning, games for STEM (Science, Technology, Engineering, Mathematics) learning, assessment of digital game-based learning and pervasive and ubiquitous gaming for learning. In addition to the presentations of research we are delighted to host the third year of the Serious Game competition, which provides an opportunity for educational game designers and creators to participate in the conference and demonstrate their game design and development skills in an international competition. This competition is again sponsored by SEGAN - Serious Games Network. With an initial submission of more than 60 games, 28 finalists will present their games at the conference. Prizes will be awarded to the games judged to demonstrate the best quality and originality of game play itself and the positioning and articulation of the game's contribution to the educational domain. With an initial submission of 190 abstracts, after the double blind peer review process, there are 75 research papers, 15 PhD research papers, 4 Non Academic papers and 8 work-in-progress papers published in these Conference Proceedings. These papers represent research from more than 40 countries, including Australia, Austria, Belgium, Brazil, Bulgaria, Canada, Czech Republic, Denmark, Finland, France, Germany, Greece, Hungary, Ireland, Israel, Italy, Japan, Malaysia, Norway, Portugal, Russia, Saudi Arabia, Slovakia, Slovenia, South Africa, Spain, Sweden, Switzerland, Taiwan/ROC, The Netherlands, The Netherlands, United Arab Emirates, UK and USA
