You are not the only one
to face problems
Analysing breakdowns is a good heuristic
Teachers:
Researchers:
Loss of "time habits"
Confusion between flexibility and workload
How do we count time for students?
How do we count time for teachers?
Time is our bottleneck (more than bandwidth)

Constructivism versus Learner Control
Deep versus shallow interactivity
>> Innovative situations are fragile
Example 1(TECFA Virtual Campus):
Goal: Discover common mistakes in writing
multiple choice questionnaires
This is not scientific research, just teacher experience, but raise
interesting issues
eLearning is not more fragile, but, in case of problems, adaptation is more
difficult
Example 2 (TECFA Virtual Campus):
Goal: Discover relationship between learning
theorie and families of educational software
Design choices
Immediate FB
Delayed FB
Microworld FB
