In this paper we present the results of an evaluation study of a development project for the introduction and use of tablet computers (iPads) at the lower secondary level in Nordlinga school, a compulsory school in Reykjavík. In the study, we assess the impact of the use of tablet computers on instruction and students' learning in grades 9 to 10, and on school development in Nordlinga school. First results show that that the project came to a good start, despite some differences that the school had with city administrators and technical problems in the beginning. Most students brought their tablet home and used it for formal, as well as informal and non-formal learning. The introduction of tablet computers enabled access to a variety of software for learning, tools and games. It stimulated communication and collaboration. Products of learning increasingly involved multimedia elements and networking. The study indicated increased satisfaction, interest and independence of students in learning, development of individualized learning strategies, increased student engagement and an improved use of class time. Teachers felt that the use of tablet computers stimulated their professional development and enhanced their work satisfaction. Parents were generally supportive of the use of tablet computers and considered it important that the school could continue to invest in new technologies for learning. Indications were of insufficient availability of learning materials in Icelandic and a start of co-configuration of partners to remedy the situation. The evaluation revealed some weaknesses, challenges and opportunities for further development. [For the full proceedings, see ED562140.]
