- Abstract
We analyze the responses of first and third-year students of secondary school to a problem-situation on the Stern- Gerlach experiment, presented to introduce the concepts of: state of a physical system and linear superposition of states and others, during a course about principles of quantum mechanics. Also, the course was related to other problemsituations that will not be discussed in this paper. Part of the students was evaluated through a test, at the end of one of the classes; and all of them through a written examination at the end of the course. We used the Meaningful Learning Theory of Ausubel and the Conceptual Fields Theory of Vergnaud, as theoretical framework, and for to design the course and to analyze the collected data. It was possible to verify (according to the assessment scale adopted) a lack of homogeneity between the groups of students, indicating that their understanding of concepts occurred in different ways. Nevertheless, more than half of them showed an adequate response to the proposed questions; only one of the groups presenting a statistically significant difference, according to Student's t-test results.
