C. H. Muntean, G. Muntean, J. Mcmanis, and A. Cristea, Quality of Experience- LAOS: create once, use many, use anywhere. International Journal of Learning In this deliverable we have summarized the work done in the WP1 Personalized Adaptive Learning during the lifetime of the PROLEARN project, attempted to map the current situation, and finally outlined future perspectives in this field, It is our belief that PROLEARN Network of Excellence helped in identifying the crucial issues in the field of personalized adaptive learning and in addressing them either directly in this project or via initiating new ones, 2007.
