| Crynodeb: | This paper examines and reflects on the explanatory resources that are used in high school physics classes for studying the topic of energy. Explanatory resources are a means of constructing and negotiating meaning. The research is an instrumental case study focusing on four years of high school physics classes on energy. The theoretical principles of sociocultural approaches and conversation analysis are taken as benchmarks for understanding how we construct and reconstruct meanings (on energy). The identification of the resources used in the process of meaning construction is of importance for understanding certain scientific phenomena addressed in the curricula. Among the resources most commonly employed to enhance explanation were definitions and the causes of phenomena. We also found that teachers’ interventions, either through verbal explanations or instructional proposals, were crucial for certain kinds of explanations and for the presence or absence of other resources associated with explanations. |
