4. Registration/Login Dialogue

5. Registration/Login Dialogue
• Choose login name/password
• Sometimes students enroll into
special groups in order to
receive special treatment
strategy, or particular courses
only
• Important legal clause – saving
personal data, depending on the
country this might be subject to
changes
• Full name and email address are
optional
• Entering field of interests might
affect the adaptation of
examples in generated courses
• Specifying learning context
restricts access to the material
to those suitable for this context

6. Extended Book Concept : 3-Panel Interface
‣ Table of Contents on the left, hierarchical menu
‣ Sequence of Learning Objects in the middle panel
‣ Related concepts and other Metadata in the right panel

7. Extended Book Concept : Defining Bookmarks
Click to bookmark this page
The check box indicates a bookmark
Bookmarks show up
in a separate panel
in the dashboard

8. Left panel: Table of contents with progress indicator
Hierarchical
structure
Progress indicators
using percentages

9. Left panel: progress indicators
• Success indicators can have different modes showing different kind of progress
• If the indicator type is set to success, only correctly solved exercises contribute

10. Left panel: progress indicators

11. Left panel: progress indicators
• If the indicator type is set to success, only correctly solved exercises contribute
Exercise incorrect
No success indicated

12. Left panel: progress indicators
• If the indicator type is set to effort, then all attempts contribute, even the wrong ones
Exercise incorrect
Success indicates a
solution attempt

13. Left panel: progress indicators
• If the indicator type is set to mastery, then the success can also decrease
Exercise incorrect
Success decreases
with incorrect solutions

14. Left panel: progress indicators
• If the indicator type is set to none, then no success indicators are shown

15. Right panel: Metadata of an item
• Title and type of the Learning Object
• Authors, Editors, Date of Creation, other general Metadata
• License of the Learning Object

16. Right panel: Metadata of an item
• Languages in which the item is available
• Relations to other items

17. Right panel: Switching Language of a LO
Switching the language here will
affect the selected learning object

18. Right panel: Switching Language of an LO

19. Right panel: Social voting feature
• Distribution of votes by different users result into percentage of red and
green colors
• Public comments as well as private notes can be attached to an item
• Problems in content and system can be reported to the developers

20. Semantic Search Function

21. Semantic Search Function
Find exercises
about derivatives
Click on one
exerciseThe exercise opens
in a new tab and
can be solved

22. Adaptive Course Generation
Choose a Scenario
for the Course-
Generation

23. Choose the topic
(one or more
concepts or a
course chapter)
Adaptive Course Generation

24. Review the
summary of the
course generation
parameters
Adaptive Course Generation

25. Generated course is
adapted to the
learner
Adaptive Course Generation

26. Micro- Course generation
• Near each exercise there is a button „more about the topic“
• A micro course about the focus concepts of the exercise is generated
on click
• If the course is not adapted to the user, it always contains all the
information about the topic and its prerequisites

27. Micro- Course generation
• A generated static micro course can be very big, almost not
“mirco” any longer
• It might be better if it is adapted to the learner
• The course is then much smaller
• The learner only gets information he does not already know
• Examples in the course are adapted to the learner as well

28. Formula editor and further interactive elements
• Formula Editor enables input of mathematical formulas
• Exercises with simple answers can be solved without formula editor
• Formula editor can work with different palettes

29. Exercises types: Self Assessment
• Solve a Self-assessment exercises on the paper
• Compare your solution with the given model solution
• Estimate the correctness on own solution

30. Exercises types: multiple choice
• Single or multiple answer exercises possible
• Flag Feedback via coloring the chosen answers red or green, plus
correct/wrong symbols

31. Exercises types: fill in blank
• Use formula editor for entering answers
• Flag Feedback is presented in a form of coloring and special correct/wrong
symbols

32. Exercises with intelligent Feedback using CAS
• „Flag Feedback” (Correct/Wrong)
• Matching exact answers, as well as semantically equivalent

33. Intelligent exercises using Domain Reasoners
• „Flag Feedback” (Correct/Wrong)
• Matching various correct (expert) solution paths
• Error Feedback for typical errors via matching buggy-rules

34. Intelligent Exercises using Domain Reasoners
• Generated Next-Step hints on student’s solution path
• hints with increasing level of detail
• Generated Worked out solutions

35. Further interactive Elements
• Arbitrary external multimedia can be integrated into the system
• A web2.0-based Framework allows for communication of integrated
external content with the user model
