This study is a review of works focusing on interlocutions between Freire's and Vygotsky's thinking on school education. It aims at eliciting and clarifying the main elements explored in such connections. In methodological terms, this research is a review of records of education and science education events. Through discoursive textual analysis, we have studied language, knowledge conception and mediation as connections between Freire's and Vygotsky's ideas. We have observed that the identified studies do not provide the needed attention to problematization, an essential category for Freire, and they barely explore the conceptual signification based on Vygotsky. Considering the necessary changes in science teaching, these categories may contribute to elementary students' involvement and learning level.
