Outline

• Context

• Learning by writing hyperbooks

• Libraries of hyperbooks

• Extension

• Learning by conceptualizing

• Assess concept understanding

Context: Hyperbook writing

Objectives

• Learning by writing hypertexts

• Transverse view of the course

• Show relationships between concepts

• Not in the classroom presentation order Blended learning

• Classroom lectures +

Next Step

• Let the student create their own conceptual structures

• Evaluate how students understand the concepts of a course

ED-MEDIA 2005 University of Geneva - CUI - ISI

Concept map creation

Former results

• deeper understanding of the topic

• students are more active

• lack the possibility to explain a concept in words

• resulting maps are usually of poor quality

With Hyperbooks

Simplify and enhance students’ expression

• create concepts and semantic links

• create “old-style” textual chunks with their own words

• connect formal and informal expressions

Facilitate the comparison between conceptual

structures

ED-MEDIA 2005 University of Geneva - CUI - ISI

Process - conceptualizing & writing

Groups of students create their hyperbooks

ED-MEDIA 2005 University of Geneva - CUI - ISI

Process - comparison

Reference hyperbook

Comparing Conceptual Structures

Difficult problem

• Different terms for the same concept

• Several "correct" solutions

• Different modeling competencies Comparison technique based on

• conceptual structure (terms, and relationships)

• and attached text fragments

Output: Similarity links between concepts of different hyperbooks

(7)

ED-MEDIA 2005 University of Geneva - CUI - ISI

Process - discussion

Integration

Annotation

ED-MEDIA 2005 University of Geneva - CUI - ISI

Discussion phase

Interconnected hyperbooks

=> a global navigation space

View other perspectives on the same concepts Attach remarks, positions, arguments to notes

Summary of the process

• Brief introduction to conceptual structures

• Groups create their hyperbooks

• Comparison with a reference hyperbook

• Integration, discussion, improvement

(8)

ED-MEDIA 2005 University of Geneva - CUI - ISI

Conclusion

• Assessment through hyperbook writing

• Based on concept comparison/mapping

• Using existing hyperbook software

• First experiment

• "Semantic web" course, Oct. 2005 (master)
