O International GeoGebra Institute – IGI é uma organização sem fins lucrativos que desenvolve seu trabalho juntamente com Institutos GeoGebra independentes oficializados em diferentes países. Atualmente os Institutos GeoGebra estão presentes em todos os continentes.

Os Institutos Internacionais de Geogebra (IGI) são organizações sem fins lucrativos e foram criados devido à ampla divulgação e uso do software livre GeoGebra. Em cada Instituto e em todos os continentes, professores e pesquisadores trabalham juntos para promover o ensino e a aprendizagem da Matemática apoiando e desenvolvendo as seguintes atividades:

Desenvolver materiais gratuitos para oficinas de GeoGebra;
Oferecer oficinas para professores e para futuros formadores sobre o GeoGebra;
Desenvolver e implementar novas funcionalidades do software GeoGebra;
Desenvolver um sistema de apoio on-line para professores;
Avaliar e melhorar as atividades de desenvolvimento profissional e materiais;
Projetar e implementar projetos de pesquisa com o GeoGebra e para os IGI;
Comunicações em conferências nacionais e internacionais.

Em linhas gerais os Institutos GeoGebra, por meio do software livre GeoGebra, compartilham experiências sobre capacitação para o uso do GeoGebra, oferecem suporte para o desenvolvimento de materiais por estudantes e professores para o aprimoramento da Educação Matemática, Ciência e Tecnologia, procuram promover a colaboração entre os profissionais e pesquisadores, buscando estabelecer parcerias e a formação de uma comunidade de usuários do GeoGebra.

O grupo de pesquisa Tecnologias e Meios de Expressão em Matemática (TecMEM) do Programa de Estudos Pós-Graduados em Educação Matemática da PUC/SP e o Curso de Ciência da Computação têm sob sua responsabilidade o Instituto GeoGebra de São Paulo, com sede na Faculdade de Ciências Exatas e Tecnologia da PUC-SP.
