Résumé

Para treinar futuros matemáticos precisam ser confrontados com tarefas que devem agir como tal. No trabalho descrito neste artigo, um grupo de alunos têm de enfrentar uma nova definição para eles: o conceito de número feliz, devem extrair informação que permita um entendimento para gerar exemplos que atendem à definição, para identificar non-exemplos e encontrar organizadores não genéricos para a construção de espaços de exemplos e, eventualmente, resolver uma situação em que estes números estão envolvidos. As interações en el grupo foram registradas e analisadas utilizando o modelo RBC-C (Schwarz, Dreyfus & Hershkowitz, 2009) para documentar a forma como o processo ocorreu. Os resultados mostram que, apesar de alguns erros que eles mesmos estão conscientes, os alunos estão entusiasmados com a tarefa e começa a ir além do que está sendo proposto.
