Elica Project

• Acronym Educational Logo Interface forCreative
  Activities
• First steps Initial development supported by a
  Grant Award by Best Practices in Education
• Usage In schools and universities all over the
  world (except for Antarctica)

DALEST Project

• Acronym Developing an Active LearningEnvironment
  for STereometry
• Partners Universities of Cyprus, Southampton,
  Lisbon, Sofia, Athens N.K.M Netmasters and
  Cyprus Mathematics Teachers Association
• Co-funded by the European Union under the
  Socrates Program, MINERVA, 2005 Selection.

DALEST Objectives

• To analyze the existing stereometry curricula and
  teachers requirements
• To develop a dynamic 3D software and teaching
  scenarios for stereometry
• To provide in-service training
• To test the software and the teaching approaches
  in different schools and evaluate their
  effectiveness.

Solids with Solid Edges
Leonardo da Vincis The Divine Proportion (1509)

• The 1st illustrations of polyhedra ever in the
  form of solid edges
• Readers can see through to the structure of the
  rear surface
• Illustrations in pairs modelswith solid faces
  and solid edges
• A new form of insightful geometric illustration

Stereometry

Studying Solids

• Heads-on activities

• Traditional methods
• textbooks
• hand-made drawings
• real models

• Modern methods
• on-line textbooks
• 3D software, virtual models
• interractive, dynamic content

3D Software

DALEST/Elica Project

• DALEST Two software streams
• A monolith application Eucli3D
• A set of separate Elica applications

• Main Challenges
• Unique problems
• To rationalize use of computers
• Attractive visualization

17
Possible Elica Applications

• Ideas about 20 different applications
• New ideas are added all the time
• Ideas cover various topics
• Volumes of solids
• 3D structures and space relations
• Nets
• Art and Nature
• Four ideas implemented so far
