For the first time, the annual conference of the European Association for Computer-Assisted Language Learning (EUROCALL) took place in Sweden. The conference took place at the Faculty of Education on historic ground on the old fortification walls of Carolus Dux from the 17th century right in the centre of the city. This year's host comprised the University of Gothenburg in collaboration with Chalmers University of Technology. The local committee members represented three collaborating institutions: "Faculty of Education, the University of Gothenburg"; "Department of Languages and Literatures, the University of Gothenburg"; and "Division for Language and Communication, Chalmers University of Technology." This year's conference theme was "CALL: using, learning, knowing." The conference seeked to establish the current state of the art, how using technologies shape what and how we learn, and what we consider we know from research and development within CALL. These three dimensions are in a continuous fux and interplay as an upward spiral, contributing together to create a dynamic learning experience for the student. There were presentations presented at the conference. 59 of these were submitted as extended papers and appear in this volume of proceedings. An author index is included. (Individual papers contain references.)
