– display recommended items (content)

– display recommended authors (users)

MOT 2.0 Design Questionnaire

• 30 3rd year students ( web programming)

• Who/Where/What questions

• Compared our design with students’ answers

Results

• Consistent association between the teachers and the students

• All users are authors• Collaboration is based on rating,

tagging and content feedback.• The privileges are defined at the level of

the lesson and the link in the goal model.
