3
The MOT AM

• Represents an implementation of the AM layer in
  LAOS

4
LAOS

• based on AHAM
• supporting adaptive hypermedia authoring
• five layers
• Domain Model (DM)
• Goal and constraints Model (GM)
• User Model (UM)
• Adaptation Model (AM)
• Presentation Model (PM)

MOT UM Role

• The user model in MOT is supposed to
• connect all other models with eachother (DM, GM,
  UM, PM)
• is the only specification of the dynamics of the
  adaptive hypermedia

7
Please note!

• Course 7 gives more details on the AM in MOT,
  these are just some extra information

8
Reminder extra explanations

• The (sub-)lessons in the lesson (GM) model are
  grouped in lesson groups
• This is why the parent of a lesson is the
  (unique) group to which this lesson belongs
• In the current implementation, the child points
  to the (set of) children of all groups at the
  current level

Revisiting the child-parent relation in a strategy

• initialization (
• while true (
• PM.GM.Concept.show false
• )
• '\Neural Networks II\Neural Networks
  I\title'.show true
• )
• implementation (
• if (UM.GM.Concept.access true)
  (GM.Concept.child.parent.order lt 9)
• then (
• PM.GM.Concept.child.show true
• )
• if (UM.GM.Concept.access true)
  (GM.Concept.parent.parent.child.child.parent.order
  GM.Concept.parent.order1) then (
• PM.GM.Concept.parent.parent.child.child.show
  true
• )
• )

• Lets look at these two IFs separately

14

• if (UM.GM.Concept.access true)
  (GM.Concept.child.parent.order lt 9)
• then
• (
• PM.GM.Concept.child.show true
• )

15
If a concept from a lesson (GM) was accessed ..

• if (UM.GM.Concept.access true)
  (GM.Concept.child.parent.order lt 9)
• then
• (
• PM.GM.Concept.child.show true
• )

16
.. and if there exists 1-more group(s) of
concepts at the same level with the accessed
concept

• if (UM.GM.Concept.access true)
  (GM.Concept.child.parent.order lt 9)
• then
• (
• PM.GM.Concept.child.show true
• )

17
.. and if the order of these groups of concepts
are smaller than 9 ..

• if (UM.GM.Concept.access true)
  (GM.Concept.child.parent.order lt 9)
• then
• (
• PM.GM.Concept.child.show true
• )

18
.. then show all the children of these groups of
concepts

• if (UM.GM.Concept.access true)
  (GM.Concept.child.parent.order lt 9)
• then
• (
• PM.GM.Concept.child.show true
• )

• if (UM.GM.Concept.access true)
  (GM.Concept.parent.parent.child.child.parent.order
  GM.Concept.parent.order1)
• then
• (
• PM.GM.Concept.parent.parent.child.child.show
  true
• )

21
If a concept in a lesson (GM) was accessed ..

• if (UM.GM.Concept.access true)
  (GM.Concept.parent.parent.child.child.parent.order
  GM.Concept.parent.order1)
• then
• (
• PM.GM.Concept.parent.parent.child.child.show
  true
• )

22
.. and if there exists a group concept with a one
step higher order than that of the parent of the
current concept ..

• if (UM.GM.Concept.access true)
  (GM.Concept.parent.parent.child.child.parent.order
  GM.Concept.parent.order1)
• then
• (
• PM.GM.Concept.parent.parent.child.child.show
  true
• )

23
.. then show the children of that parent concept.

• if (UM.GM.Concept.access true)
  (GM.Concept.parent.parent.child.child.parent.order
  GM.Concept.parent.order1)
• then
• (
• PM.GM.Concept.parent.parent.child.child.show
  true
• )

24
In other words

• Show (display to the user) all the sub-concepts
  of the following group

Final notes

• These were examples of strategies that you will
  edit in any text editor
• you will need to create such strategies for your
  project, as stated in the project file
• The results of your created AM maps you will have
  to demonstrate and explain at the final project
  presentation
• You will also get a questionnaire about this
  process
