ab: Summary: When quantum theory caused a paradigm shift in physics, it
introduced difficulties in both learning and teaching of physics.
Because of its abstract, counter-intuitive and mathematical structure,
students have difficulty in learning this theory, and instructors have
difficulty in teaching the concepts of the theory. This case study
investigates students’ comprehension of some fundamental concepts
which are based on quantum mechanical postulates. The data of the study
were collected by forty minute semistructured interviews with two
pre-service physics teachers conducted separately. In this study,
qualitative analysis of pre-service physics teachers’ dynamics of
understanding showed that (1) students have insufficient conceptions
that influence their descriptions and discriminations, (2) students’
comprehension is indefinite, that means, they contain correct and wrong
ideas simultaneously, influencing the students’ use of different
concepts interchangeably and making explanations and discriminations by
intuitive reasoning, and (3) some of the conceptions of students are
totally unscientific. In addition, students’ comprehension lets only
one way translation from mathematical to verbal.
