Adaptation Introduction Modify process execution “on the fly” Evaluation of Adaptations Process Evaluation Adaptation Integration Select adaptations which mean an improvement Make changes permanent

Telmo Zarraonandia Laboratorio DEI. Dpto. de Informática U. Carlos III de Madrid IMS Learning Desing: What do we need? A notation to specify the monitorizations A notation to specify the adaptations A notation to specify the learning objectives evaluations Create a evaluation profile for the UoL A mechanism to modify the process “on the fly” Introduce the adaptations... To observe process evolution at any time....
