International GeoGebra Institute (IGI)

• for the majority of teachers it is insufficient
  to only provide free software
• Training and collegial support enhances their
  willingness to integrate technology into their
  teaching
• ? Teachers need a support system and professional
  development
• ? International GeoGebra Institute (IGI)

Goals

• The International GeoGebra Institute
• Teacher Training and Supportprovides free
  workshops and materials for teachers and future
  GeoGebra trainers to create and support a
  self-sustaining community of users
• Research and Developmentcontinues to enhance
  GeoGebras capabilities and ease-of-use, based on
  research
• We look for any kind of collaboration from
  interested people
