MOT new version
• Many evaluations have been made with
the old MOT
– (see papers on evaluation at:
http://www.dcs.warwick.ac.uk/~acristea/HT
ML/ftp_paper_chrono.html)
• This resulted in a new version, as
follows

MOT system components
1. An interface for creation of content
http://prolearn.dcs.warwick.ac.uk/MOT/
– Creates Conceptmaps and Lessons
2. An interface to upload adaptive strategies
http://prolearn.dcs.warwick.ac.uk:8022/aha/author/AMt/AM
t.html
– Adaptive strategies are created as text
documents in the latest version (the old interface
is incompatible)

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 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

Concept attributes in the

• Should contain ONLY domain-related
content
• So: no prerequisites, no pedagogic

Editing a domain attribute
• text input window in the left hand panel
• cut& paste any type of text you wish,

• Condition: you are the author of this

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:

Bugs & known problems
remaining in the new MOT
• If 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).
