Enhancing English Composition Studies Through Multimedia Tutoring System: A Marking-Based Approach

This system focuses on creating hypermedia presentations for educational use, specifically for correcting English composition. It enables students to submit writing, uses speech instructions, and allows for synchronized presentation and random access features. The system also includes spatial correlations such as free-form handwriting and tele-pointer movements, along with temporal correlations for smoother interaction. Experimental results include speech turn clustering, random visual event access, and undo functionality. A user study conducted in Spring 2006 showed favorable reactions to the system's usefulness and design, indicating its potential for practical applications.

Presentation Transcript

  1. WMA: A Marking-Based Synchronized Multimedia Tutoring System for English Composition Studies By Herng-Yow Chen and Kuo-Yu Liu Presented by Brett Lilley

  2. Evolution of the Web • Hypertext: • Document with hyperlinks to other documents • Content-based • Hypermedia: • Hypertext with graphics, audio, video • Time-based

  3. Problem Statement Creation of hypermedia presentations for educational use. Focus on correcting English Composition

  4. Creating Hypermedia • Authoring • Media Correlation • Publishing • Integration

  5. Better Educational Solution – Presentation Recording • eClass • Authoring on the Fly

  6. Web-Based Multimedia Annotation (WMA) System • Enable students to submit writing via the Web • Capture speech instructions • Capture the navigation events • Hot Keys • Mouse Operations • Ensure synchronized presentation with automatic navigation features • Enable random access throughout the hypermedia document

  7. Inter-Media Relationships

  8. System Architecture

  9. Temporal Correlation • Discrete Media • Navigation Events • Continuous Media • Speech • Random Access Between the Two

  10. Spatial Correlation

  11. Spatial Correlation: Free-Form Handwriting

  12. Spatial Correlation: Free-Form Handwriting Problem

  13. Adaptable Handwriting Presentation

  14. Spatial Correlation: Tele-Pointer • Discussion Clues • Capturing/Storing Issues

  15. Tele-Pointer Movement Interpolation • Interpolation Smoothing Algorithm • Number of Interpolated Pointers • Distance Interval • Timestamp and Positions • Time Interval - Crucial

  16. Content Correlation – Undo And Random Access

  17. Speech-Event Binding

  18. Undo Facilitation • Timestamps of events do not match speech stream timestamps • Recording is contiguous – cannot delete on-the-fly • Delete during speech-event binding

  19. Experimental Results:Clustering Speech Turns

  20. Experimental Results: Random Visual Event Access

  21. Experimental Results:Undo Functionality • Compare Against Manually-Created Speech Segments • 71% Match – Lower than Random Access

  22. Experimental Results:Tele-Pointer Interpolation • Interviewed 20 Students • >80 ms = Decreased Fluidity and Sickness • 50 ms Used in WMA

  23. Experimental Results: User Study • When: Spring 2006 • Where: Computer Science and Information Engineering at Chi Nan University • Who: 2 instructors, 27 Ph.D. students, 25 graduate students

  24. Survey Results • Favorable reactions to perceived usefulness of WMA • Integration of emerging technologies for learning is attractive to students • Favorable reaction to design and features.

  25. Pre- and Post-Test Results

  26. Conclusion • Overall system evaluation is good for practical applications • Learners get what they put in • Improvements can be made by customizing the Speech-Event Binding process
