MOT new version

• Many evaluations have been made with the old MOT– (see papers on evaluation at:

http://wwwis.win.tue.nl/~acristea/HTML/ftp_paper_chrono.html)

• This resulted in a new version, as follows

MOT system components

1. An interface for creation of contenthttp://prolearn.dcs.warwick.ac.uk/MOT/http://prolearn.dcs.warwick.ac.uk/MOT/

– Creates Conceptmaps and Lessons

2. An interface to upload adaptive strategieshttp://prolearn.dcs.warwick.ac.uk:8022/aha/author/AMt/AMt.htmlhttp://prolearn.dcs.warwick.ac.uk:8022/aha/author/AMt/AMt.html

– Adaptive strategies are created as text documents in the latest version (the old interface is incompatible)

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)

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

• As all maps (domain or goal and constraints) are built on the concept model paradigm, they are all concept mapsconcept maps as well

1. 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

1. 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

MOT Domain map

• Consists of a hierarchy of concepts and their attributes

Concept attributes in the Domain (Concept) map

• Should contain ONLY domain-related content

• So: no prerequisites, no pedagogic information

Uploading other files/content

Editing a domain attribute

• text input window in the left hand panel

• cut& paste any type of text you wish, – including (X)HTML/ XMLincluding (X)HTML/ XML !!

• Condition: you are the author of this domain map.

1. 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)

Note:

• The meaning of the weights & labels is given by the adaptation strategy!

Bugs & known problems remaining in the new MOT• If you use html or other tagstags 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).

• Any questions?
