Invited Tutorial, Madrid, Spain April 2008 Changes Look and feel Naming Click distance Confirmation for deletes. Uploading of files other than in text (text, HTML, XML) format (e.g., pictures or videos, slides)

Invited Tutorial, Madrid, Spain April 2008 Naming The LAOS naming conventions are respected more carefully a clear separation is made between the name ‘map’ denoting an instance, and the name ‘model’ denoting the schema concept mapsAs all maps (domain or goal and constraints) are built on the concept model paradigm, they are all concept maps as well

Invited Tutorial, Madrid, Spain April Content creation in MOT Domain Concept maps: –Are called as in LAOS, domain maps –They still keep the name ‘Concept maps’ for ‘backward compatibility’ – they have the same structure of concepts with attributes –Represent the domain model (e.g., of the course) –Book-like hierarchical structures –Contain the links to the actual resources (via attributes) –Allow also non-hierarchical links (relatedness links) –Order of concepts or attributes of (almost) no importance

Invited Tutorial, Madrid, Spain April Content creation in MOT Goal maps: –Are the ‘Goal and constraints maps’ from LAOS –The previous name, ‘Lessons’, also appears, for ‘backward compatibility’ –They are obviously also Concept maps (with attributes) –Represent the goal and constraints model e.g., represent the pedagogical view on the course –A filtered (ordered, weighted and labeled) version of the domain maps, with pointers to the original content

Invited Tutorial, Madrid, Spain April Content creation in MOT: Goal maps* Represent the Goal and Constraint maps (thus instances) of the model with the same name in the LAOS model: goal and constraints model They still keep the name ‘lessons’ for backward compatibility, and also because MOT is primarily aimed at the educational domain (unlike the LAOS model, which is more generic) –E.g., lessons represent the pedagogical view on the course Concept maps (with attributes) A filtered (ordered, weighted and labeled) version of the domain maps, with pointers to the original content –The order is interpreted as order in which the contents (concepts) should be seen –The labels give qualitative information about the contents –The weights give quantitative information about the contents –Weights and labels are only allowed for groups of concepts connected with an OR, to inform about the comparative desirability of the list of concepts. (if concepts are connected with an AND, they should be interpreted as equally desirable)

Invited Tutorial, Madrid, Spain April 2008 Changing weights & labels for sub-lessons

Invited Tutorial, Madrid, Spain April 2008 Note: The meaning of the weights & labels is given by the adaptation strategy!

Invited Tutorial, Madrid, Spain April 2008 Bugs & known problems remaining in the new MOT tagsIf you use html or other tags with MOT, then the lesson view might behave irregularly (because the teacher view truncates the text). The solution is NOT to have html tags in the first 30 characters of the text (or to close them within the first 30 chars).
