The aim of this
study is to develop a conceptual understanding scale on Insufficiencies of
Classical Physics concerning Quantum Physics Courses. In the first stage, 36
items were developed, depending on the target behaviours and the scale was
transformed into 33 items with the opinion of two expert academicians. The draft
scale was then applied to 139 (40 male 99 female) pre-service teachers from the
departments of Science Education and Physics Education at a state university.
Following the item analysis efforts, final version of the scale with a total
number of 20 items, has been obtained. The Cronbach Alpha reliability
coefficient of the final scale was found to be 0,78.
