  1. Learning through Ad-hoc Formative Paths ICALT 2001 Vincenza Carchiolo, Alessandro Longheu, Michele Malgeri Informatics and Telecommunication Department Catania University - Italy e-mail: { car, alongheu, mm } @ diit.unict.it 6-8 August 2001, Madison, Wisconsin USA

  2. ICALT 2001 E-Learning Empowering E-L - Developed inside specific environments (e.g. industries) Developing contents to heterogeneus students, differing for knowledge, and learning rate. Need to tailor courses for each student. - Homogeneus contents to homogeneus communities Web boost - Increasing bandwidth availability - PC as enhanced terminals for web-based applications 6-8 August 2001, Madison, Wisconsin USA

  3. ICALT 2001 Goals - Encourage active learning techniques - Adjust formative (learning) path to students capabilites - Learn how to use students available time - Have an immediate feedback of each students activity 6-8 August 2001, Madison, Wisconsin USA

  4. ICALT 2001 Summary - Introduce a framework for interactive, adaptative E-learning - Graph-based lessons repository - Weighted and adaptable formative paths along the graph - Tests, exercises, chatrooms, mailing lists, contacting teacher to assure interaction - Present a prototype for E-learning in a web-based environment 6-8 August 2001, Madison, Wisconsin USA

  5. ICALT 2001 Graph-based E-learning model - 1 • Each node represents a subject matter • (one-argument lessons) • Each oriented weighted arc measures the difficulty • (time and knowledge required) • moving from one lesson to the next 6-8 August 2001, Madison, Wisconsin USA

  6. ICALT 2001 Graph-based E-learning model - 2 - Weights are managed by the teacher 6-8 August 2001, Madison, Wisconsin USA

  7. ICALT 2001 Graph-based E-learning model - 3 - The system automatically proposes to each student all possible paths existing between two arguments, according to student’s knowledge (profiling) - Paths are given in terms of both difficulty and time needed - Paths are adapted dynamically to student’s needs. 6-8 August 2001, Madison, Wisconsin USA

  8. 1 2 3 4 5 6 ICALT 2001 Graph-based E-learning model - 4 Student B Student A 6-8 August 2001, Madison, Wisconsin USA

  9. ICALT 2001 Test and Exercises - Test with multiple choice questions automatically generated (random) - Exercise with open response - Mark expressed in percentage - On-line results checking for tests, off-line for exercises - Additional files related to the question can be easily added 6-8 August 2001, Madison, Wisconsin USA

  10. ICALT 2001 System Interaction - FAQ Database on specific subject for students - Mailing lists and chatrooms for students - Database containing students profiles to adapt the system - Feedback to the student given online (tests) and offline (exercises) - Feedback to the teacher from log files to recalibrate lessons and tests 6-8 August 2001, Madison, Wisconsin USA

  11. ICALT 2001 Prototype architecture - 1 Users Web-based environment (lessons, tests and exercises, mailing lists, chatrooms…) Slides Electronic Documents My SQL Database APACHE Web Server Images PHP Module Videos 6-8 August 2001, Madison, Wisconsin USA

  12. ICALT 2001 Prototype architecture - 2 6-8 August 2001, Madison, Wisconsin USA

  13. ICALT 2001 Future works - refine the evaluation of difficulty for each lesson - enhance the prototype - testing of the system is in progress... 6-8 August 2001, Madison, Wisconsin USA

  14. ICALT 2001 Conclusions • A framework for an interactive, adaptative E-learning has been introduced. • Graph-based lessons repository to build and adapt formative paths • Tests, exercises, chatrooms, mailing lists, to assure interaction • A prototype for E-learning in a web-based environment has also been introduced E-Mail: { car, alongheu, mm } @ diit.unict.it 6-8 August 2001, Madison, Wisconsin USA
