Interactive Adaptative E-Learning Framework: Tailoring Learning Paths for Diverse Students

DESCRIPTION

This paper presents a framework for interactive and adaptative e-learning, developed to cater to the diverse needs of heterogeneous student populations. Utilizing a graph-based model, the framework introduces weighted formative paths for students that consider their individual knowledge and learning rates. The system dynamically adapts learning materials, offering immediate feedback and encouraging active learning techniques. Key components include a lessons repository, tests, exercises, and interactive platforms such as chatrooms and mailing lists, aimed at enhancing user engagement and optimizing learning outcomes.

  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
