This article results from a thesis for a master's degree developed in the Graduate Program in Science Teaching (PPGEC). The study aims to analyze the formulation and resolution of problems (FRP) from a question involving the concepts of volume and capacity by high school graduates. The research is based on the Theory of Conceptual Fields, highlighting the types of situations that provide meaning to the concepts of volume and capacity (measurement, comparison, and production) and the schemes mobilized by the students in FRP. The research was conducted in a School of Marine Apprentices (EAM) located in the metropolitan region of Recife in Pernambuco, Brazil. In total, 61 students participated, distributed in three groups. Each student was asked to formulate and solve a problem based on the question: How many glasses of juice does the modern jacubeira provide more than the ancient jacubeira? The analysis criteria were guided by the identification of the types of situations, action rules, and operational invariants of the problems formulated and solved by the students. Concerning the type of activity for FRP, several students used a question different from the one proposed. Most students formed problems around measurement situations (related to the transformation of measurement units and operationalization of measures) and comparison situations. The students attributed measures for the object dimensions (jacubeira) that were inconsistent with reality, that is, too large for this type of object, which reveals their difficulty in estimating length, capacity, and volume. |
