Student Difficulties with Quantum Mechanics Formalism

TL;DR

This paper investigates common student misconceptions in quantum mechanics, focusing on their struggles with the formalism, including space distinctions, the Schrödinger equation, and measurement concepts, based on surveys and interviews.

Contribution

It identifies specific student difficulties with quantum formalism through empirical data, providing insights for targeted instruction improvements.

Findings

Students confuse physical space and Hilbert space.

Students struggle with the time-independent Schrödinger equation.

Students have misconceptions about quantum measurements.

Abstract

We discuss student difficulties in distinguishing between the physical space and Hilbert space and difficulties related to the Time-independent Schroedinger equation and measurements in quantum mechanics. These difficulties were identified by administering written surveys and by conducting individual interviews with students.
