3. Luca.botturi@lu.unisi.ch Luca Botturi – Università della Svizzera italiana Semantic Web Technologies Workshop Luxembourg, 22-23 November 2000 3 /11 e-learning Context & Goals > Corporate Training = Employees in a department = Maximize profit = Temporal and spatial independence > HE Learning Institution = Post-grad students = Maximize learning = Exploit distance (intercultural) co- operation

4. Luca.botturi@lu.unisi.ch Luca Botturi – Università della Svizzera italiana Semantic Web Technologies Workshop Luxembourg, 22-23 November 2000 4 /11 e-learning Operational Views > Teaching-Learning Process = Cognitive added-value > Collaboration = Among students = Students-Tutors = Among the teaching staff > Management = Evaluation = Quality Assessment = Content update

5. Luca.botturi@lu.unisi.ch Luca Botturi – Università della Svizzera italiana Semantic Web Technologies Workshop Luxembourg, 22-23 November 2000 5 /11 What We Would Like to Have… > Content exposition = An adaptive hypermedia application > Self assessment = An adaptive tester > Collaboration = An adaptive CSCW platform > Course production = An adaptive course editor (explanations, exercises, labs, …) > … and much more

6. Luca.botturi@lu.unisi.ch Luca Botturi – Università della Svizzera italiana Semantic Web Technologies Workshop Luxembourg, 22-23 November 2000 6 /11 … in What Form > Development Environments = … instead of course-products or teaching materials > Not too much = Edge technologies can be confusing = Provide few specific functions = Matching precise pedagogical goals > Consider both teachers and students > Facilitate Didactic Module Interchange

7. Luca.botturi@lu.unisi.ch Luca Botturi – Università della Svizzera italiana Semantic Web Technologies Workshop Luxembourg, 22-23 November 2000 7 /11 Information Modeling Issues > Content Modeling = Topics, sub-topics, concepts, … = Multimedia documents > Student profile = Identity & Category/Group = Previous knowledge = Learning habits/attitude = Interests > Teacher/Tutor/Coach Profile > […underlying pedagogical strategy]

9. Luca.botturi@lu.unisi.ch Luca Botturi – Università della Svizzera italiana Semantic Web Technologies Workshop Luxembourg, 22-23 November 2000 9 /11 User Modeling: Bayesian Nets > A statistical model for the growing knowledge of a student

10. Luca.botturi@lu.unisi.ch Luca Botturi – Università della Svizzera italiana Semantic Web Technologies Workshop Luxembourg, 22-23 November 2000 10 /11 An Example: Seaway Tracker > Test Application = Online course in Knowledge Engineering = Student collaboration with Politecnico di Milano > Adaptive Navigation and Content = Lesson Planner (Agent) trough concepts = Content selection = … i.e. personalized lessons > Tutor control = report module

11. Luca.botturi@lu.unisi.ch Luca Botturi – Università della Svizzera italiana Semantic Web Technologies Workshop Luxembourg, 22-23 November 2000 11 /11 Ongoing Projects > SWISSLING = Swiss Virtual Campus Project with 5 Universities = Graduated course in General Linguistics = Web CT > NewMinE = Swiss graduated School „New Media in Education“ = Online collaboration = Webboard

12. Luca.botturi@lu.unisi.ch Luca Botturi – Università della Svizzera italiana Semantic Web Technologies Workshop Luxembourg, 22-23 November 2000 12 /11 Conclusion > Semantics in a vertical domain = Few chosen functions = For precise pedagogical goals = In a specific context > Towards a development environment > Information modeling issues: = Content: the C-Net = User: Bayesian Networks > Thank you!
