In this reply to Elon Langbeheim's response to an article recently published in this journal, authors Smith and Villarreal identify several types of general chemistry students' misconceptions concerning the concept of particle position during physical change. They focus their response on one of the misconceptions identified as such: Given a solid sample of a substance, some students did not think that a selected particle would move far from its original position throughout the reversible physical changes of melting and dissolving. Smith and Villarreal conducted pilot studies in which they tested and refined their data collection instruments. The original data collection instruments used in the first pilot study are presented in Fig. 1 and 2. These data collection instruments were refined to their final form in the published study (Smith and Villarreal, 2015), and the authors stand by the soundness of the interpretation of their results in the published work.
