Sažetak
In this study, we investigated students' understanding of concepts related to the microscopic model of gas. We thoroughly reviewed the relevant literature and conducted think-alouds with students by asking them to answer open-ended questions about kinetic- molecular theory of gases. Thereafter, we transformed the open-ended questions into multiple-choice questions, whereby distractors were based on the results of the think-alouds. Thus, we obtained a set of 22 questions which constitutes our current version of the Kinetic Molecular Theory of Gases Concept Inventory. The inventory has been administered to 250 students from different universities in Croatia, and its content validity has been investigated trough physics teacher surveys. The results of our study not only corroborate the existence of some already known student misconceptions, but also reveal new insights about a great spectrum of students' misconceptions that had not been reported in earlier research (e.g. misconceptions about intermolecular potential energy and molecular velocity distribution). Moreover, we identified similar distribution of students' responses accross the surveyed student groups, despite the fact that they had been enrolled in different curricular environments.
