Resumo

No âmbito da reforma curricular que integra elementos da álgebra inicial, realizou-se um estudo qualitativo com estudantes do quarto e do sexto ano do ensino fundamental na Costa Rica, no período pós-pandemia. Os estudantes responderam a um questionário escrito que incluía uma tarefa de generalização fundamentada na relação funcional . Os objetivos do estudo centraram-se na análise, descrição e contraste (entre níveis escolares) das representações de generalização e das estruturas de relações funcionais manifestadas pelos estudantes. Os resultados, de uma única sessão de trabalho, evidenciam que apenas metade dos participantes conseguiu generalizar. Foram utilizadas diferentes formas de representação (predominantemente a verbal), com variações relevantes de acordo com o ano escolar. No sexto ano, um número maior de estudantes representou corretamente a estrutura e demonstrou maior consistência em seu uso. Identificaram-se ainda outros recursos na expressão da generalização, como exemplos genéricos e representações associadas à indeterminação.
