Customized learning environment
Adaptable -user profiles -courses are built
with a core and examples for each
profile -settings in each profile are saved in
user profiles -access is restricted to user
profiles -the material is presented all at once
the students is free to navigate in any
direction -notes on the learning material can be
made
Adaptive -the system learns behaviors about the
user -according to user behavior certain aspects
of the course are presented -the system adapts
to user environment computer settings, network
bandwidth -the learning material is presented
gradually, as the users advanced through tests

Tests
everyone is afraid of them
How can we help the student during the tests?

• 1. Multiple choice answers
• -we can offer hints
• -we can remove one/more answer(s)
• For each question, the score is recomputed due to
  the offered assistance.
• The student can finish successfully the test, but
  he will not get the maximum grade.
• For complex tasks (problem solving)
• -multiple tasks
• -requirements are depending on each other
• -the values computed at step k are used at step
  k1
• -errors in initial stages cancel any notable
  result
• Solution at the end of each step, the results
  are validated and the correct answers are
  provided
