Learning to construct scientific explanations: an analysis of everyday life in the Science classroom

Abstract

This paper analyzes how 8th graders proposed and revised explanations for a phenomenon in Science lessons. Guided by Ethnography in Education, we gathered data from observations of the daily life of these lessons and analyzed connections between texts, contexts and events. The results indicate the teacher’s role on the provisional and uncertain character given to scientific explanations; the use of discussions - sometimes in groups, sometimes with the whole class - as a resource through which students validated (or not) their explanations; and the interpretations given by students to the relationships between data and explanations under construction. These resources shaped the practices of proposing/reviewing explanations, which were evidenced by changes in explanatory proposals throughout events. The study offers contributions to the research area of Science Education and implications for pedagogical practice.
