This article aims to discuss the role of the research in Elementary and High School, considering as fundamental importance the conception of education from of the critical pedagogy. The research procedures aim to offer to the teacher a base for his/her work with the research in classroom, to offer the possibility of development of abilities to students, according the four focus: learning to make, learning to be, learning to live together and learning to learn. The article is organized from the following way: the Introduction, whose focus is the presentation of the subject "research in the school"; the sections "Research: What is it?"

In these sections, I discuss theoretical arguments that have supported the research activity in classroom; and "Some Considerations", where I focus limitations and perspectives about teachers' work when they use research in their classroom.
