The social instances in an experimental chemistry class in the 9th year of elementary school

Abstract

This paper seeks to present and discuss the social instances of knowledge in an experimental class, whose theme was "The corals and the physical and chemical processes", taught in a class of the ninth grade of elementary school in a school in São Bento do Sul, Santa Catarina. The research focused on the analysis of social instances in the classroom with the objective of formal instruction on the stages of two experiments called "The recycling of chalk" and "The reaction of vinegar with chalk". The construction and justification of knowledge were carried out by the teacher with the use of audiovisual resources and the presentation of communicative strategies aimed at teaching and interaction with the whole class. Discursive segments of the teacher were selected and grouped into three subcategories: production, communication and knowledge evaluation. The six discursive episodes investigated were chosen based on the identification of segments in which there was a greater degree of interaction between the teacher and the students. The results obtained presented qualitative and quantitative character and contribute to understand the social instances prioritized in the classroom, the process of construction and evaluation of knowledge, besides the ways and strategies of orientation and support of the teacher in relation to the learning processes of the class.
