Board games are specific grou...
Article
Full-text available
Adaptive e-learning systems try to improve teaching processes on Internet by providing different educational content and activities for different learners. Modern tendencies of adaptation require usage of learning styles on student grouping. Main idea of adaptive e-learning applications is to use a different pedagogical approach for each of these g...
Conference Paper
Full-text available
In last twenty years, researchers have conducted intensive research in the area of principal models, software architectures and practical system development of adaptive e-learning platforms. Brains are fascinated by great opportunities for radical improvement of the teaching process by means of applying adaptability at different levels. There are t...

With last achievements in research and practical development of adaptive hypermedia systems,ration of adaptive rules from business logic. This guarantees an ability for editing adaptive rules at run time and, thus,to manage the adaptation process in a very flexible way.they start being more and more promising for e-learning adaptable to personal le...
Conference Paper
Full-text available
In recent years, the number of adaptive applications for e-learning content delivery increased immensely. Usually, such applications have own authoring tool or use external one in order to create learning materials. However, very few authors of educational content use such systems. The reason is that the tools are rather complicated and follow mode...
Conference Paper
Full-text available
In last decade, more and more platforms for e-learning content delivery provide adaptability towards learners goals, styles and performance. Usually, such platforms rely on own authoring tool or use external one in order to create learning materials. Usually, these tools follow modern e-learning standards but are rather complicated to be used and m...
