| Abstract [eng] |
The most important objective of e-learning systems is to provide learning content which should give required knowledge and competence for learners or scientists. Such content shouldn’t be created from scratch. It should be interactively created from smaller/atomic learning objects and delivered to VO users. Learning object composition to seamless and more completed structure by learning approach is named learning service or learning scenario. Learning objects may vary from simple text document to sophisticated web services which are the most important part of VO. Therefore composition of learning service is quite complex task. However bringing on such implementation technologies like web services and portlets makes this task solvable. Composed learning service should give learning content which is called learning scenario for VO users on some particular topic. This scenario can consist of description, task and theory, modeling, experimentation, assessment and other tools or web services what can be used for learning. These learning objects may change frequently. The main problem is creation of composition solution which could be able to deliver last versions of learning objects for learners. The developed composition solution could be used for creation of modern e-learning systems. |
