This qualitative study explored a mathematics workshop for parents and the impact on a parent’s mathematical content knowledge in rational numbers, perceptions of current instructional practices, and parental beliefs in supporting their children in learning mathematics. A 6-week parent workshop on rational numbers was offered in a rural middle school. Data sources included interviews and workshop audio transcriptions. This study concluded that a mathematics workshop supports parents in developing a conceptual understanding of rational numbers and rational number operations. Furthermore, parents recognized the importance of discourse, representation, and justification for building conceptual understanding in mathematics. Parents, who participated in the workshops, were more open to the use of standards based instructional practices for developing conceptual understanding. Parental engagement in mathematics should include discourse at home to help students justify and explain their thinking. Questions related to the teaching of non-standard procedures without building a conceptual understanding hindered many parents from completely accepting new instructional practices.

The relevance of this research is justified by the importance of the work with observation and generalization of patterns, identified by researchers like Mason (1996), Lee (1996) and Vale and Pimentel (2005) as a resource to students express algebraic thinking and create algebraic expressions, giving meaning to the use of symbols. The methodological procedures to prepare the roadmap for research, analyze and implement the protocols were based in the stages of the Didactics Engineering, described by Artigue (1996). The analysis about the present resolutions in the protocols and the recordings that were made during the interviews indicate that these kind of activities are little worked in the workshops Experiences Mathematics, because teachers who give these lessons, know little about why and how work these kind of activities / Com o objetivo de verificar como atividades que envolvem observação e generalização de padrões são exploradas por professores que ministram aulas nas oficinas Experiências Matemáticas das Escolas de Tempo Integral, foi realizada uma pesquisa qualitativa, utilizando-se de entrevistas semi-estruturadas com cinco professores destas oficinas. A relevância desta pesquisa se justifica pela importância do trabalho com observação e generalização de padrões, apontado por pesquisadores como Mason (1996), Lee (1996) e Vale e Pimentel (2005) como recurso para que alunos manifestem o pensamento algébrico e criem expressões algébricas, dando sentido à utilização dos símbolos. Os procedimentos metodológicos para elaborar o roteiro de pesquisa, aplicar e analisar os protocolos foram baseados nas fases da Engenharia Didática, descrita por Artigue (1996). As análises das entrevistas indicam que atividades que envolvem observação e generalização de padrões são pouco trabalhadas nas oficinas Experiências Matemáticas porque os professores de matemática que ministram estas oficinas desconhecem o objetivo principal do trabalho com esse tipo de atividade e conseqüentemente seu beneficio para os alunos
