Граф планов обучения

Граф планов обучения (Learning Paths Graph (LPG))

Граф планов обучения (ГПО) - бесконтурный орграф, который определяет все возможные планы обучения (последовательность учебных материалов), соответствующие данной цели обучения.

To construct the LPG, for each concept of the Concepts Path Graph (CPF) related learning resources are selected from the Media Space based on the connection between the Domain Concept Ontology and the Resource Description Model. Media Space describes the educational characteristics of the learning resources. Each node in the CPF is then replaced by the related set of learning resources retrieved from the Media Space. The structure of the learning resources set is directly inherited by the structure of the Media Space.

The final graph is the Learning Paths Graph. Assuming that the Media Space does not contain circular references between learning resources, the LPG is again a simple acyclic directed graph. Although this assumption does not directly affect either the design of an Adaptive Educational Hypermedia Systems (AEHS), nor our sequencing methodology, it is necessary for avoiding infinite learning paths.

На этом этапе из графа, содержащего все доступные планы обучения, выбирается персонализированный план обучения, основываясь на характеристиках обучаемого в модели пользователя. As a result, an additional layer in the abstract sequencing layers of adaptive educational hypermedia systems, namely the Learner Adaptation Layer, which is used for selecting the personalized learning path.
