Resumo
Resumo: O objetivo central do presente trabalho foi investigar se a combinação de uma seqüência didática utilizando o Princípio de Cavalieri e a utilização de um software de geometria dinâmica pode contribuir para o desenvolvimento do raciocínio espacial no ensino médio. Os sujeitos da pesquisa eram 70 alunos do período noturno de uma escola técnica, sendo que 39 deles tiveram aulas num laboratório de informática e 31 tiveram aulas clássicas de geometria espacial. Para análise dos resultados foram utilizados testes de raciocínio da bateria BPR- 5, um teste de conhecimento geométrico sobre o tema escolhido e as notas das provas com o conteúdo proposto. Os resultados mostraram um melhor desempenho entre os alunos que utilizaram a ferramenta computacional.
