Telmo Zarraonandia Laboratorio DEI. Dpto. de Informática U. Carlos III de Madrid Level C: notifications Level B: properties and conditions IMS Learning Design Levels and Adaptation It is not possible for the designers to know in advance all the range of adaptations that may be required to apply in the future: The UoL will have to be redesigned Level A: core of IMS Learning Design

Telmo Zarraonandia Laboratorio DEI. Dpto. de Informática U. Carlos III de Madrid Situations... Reuse an existing UoL In a different context Using different resources.... Requirement to modify the process “on the fly” The learning process is not performing as we expected... Introduce small variations in the UoL withouth having to go through the redefinition process

Telmo Zarraonandia Laboratorio DEI. Dpto. de Informática U. Carlos III de Madrid LD Player Implementation: How? VISITOR PATTERN [Gamma et al.]: “To perform the same operation on the elements of an object structure and be able to define new operations without changing the classes of the elements of the structure” To perform a context adaptation operation on the activities of a Learning Design We don’t want to change the structures of the elements each time a new adaptation is required

Telmo Zarraonandia Laboratorio DEI. Dpto. de Informática U. Carlos III de Madrid LD Player Implementation: Visitor Pattern + Aspects We need an “accept” operation on the “Activity” elements Aspect Oriented Programming approach: ASPECT : The Context Adaptation Operation POINTCUT : Condition of aplication of the operation ASPECT and POINTCUTS defined separately from the rest of the components

Telmo Zarraonandia Laboratorio DEI. Dpto. de Informática U. Carlos III de Madrid Application: Contextual Adaptation

Telmo Zarraonandia Laboratorio DEI. Dpto. de Informática U. Carlos III de Madrid Concept of “Context” “Any information that can be used to characterize the situation of entities that are considered relevant to the interaction between a user and an application” [DEY] Computational Environment Agenda Age Background Preferences Learner InformationNOISE!!! Physical Environment Any relevant information that could influence the execution of a Unit of Learning

Telmo Zarraonandia Laboratorio DEI. Dpto. de Informática U. Carlos III de Madrid Application: Process 1.Obtain information about the current context of execution (Ambient Intelligence Engine) 2.Identify the context (Context Detector) 3.Introduce the appropiate variations on the normal execution of the Learning Desing process (Learning Design Player)
