Abstract Title: 3rd year university physics students’ reasoning on physical information encoded in quantum state at a point in time
Abstract: Learning quantum mechanics (QM) entails adopting a new reference frame for the physical interpretation of the world. The quantum perspective is intrinsically connected with math, which becomes a sort of referent for physical meaning, requiring the employment of new formal structures and a new interpretation of familiar ones. Different approaches in teaching QM evidenced that students struggle to draw qualitative inferences from quantitative tools. Within a research conducted in the framework of the Model of Educational Reconstruction, a 15-item questionnaire was administered to 40 physics students of three Italian universities. Semi-structured interviews were scheduled on a subset of students. Results concerning the transposition of experimental outcomes in quantum state formalism and its physical interpretation show that students mostly focus on square modulus in order to reason on physical information encoded in the state, thus neglecting phase and reconstructing the state by means of one measurement.
