Brandriet, Alexandra R.; Bretz, Stacey Lowery – Chemistry Education Research and Practice, 2014
This manuscript describes the relationship between students' redox understandings and confidence as measured by the Redox Concept Inventory (ROXCI) which assesses symbolic and particulate redox concepts. The ROXCI was administered to two samples of 1st- and 2nd-semester general chemistry students after the students were taught and tested on redox…

Brandriet, Alexandra R.; Bretz, Stacey Lowery – Journal of Chemical Education, 2014
This article describes the development of the Redox Concept Inventory (ROXCI) as a measure of students' understandings and confidence of both the symbolic and particulate domains of oxidation-reduction (redox) reactions. The ROXCI was created using a mixed-methods design in which the items were developed based upon themes that emerged from…

McClary, LaKeisha M.; Bretz, Stacey Lowery – International Journal of Science Education, 2012
The central goal of this study was to create a new diagnostic tool to identify organic chemistry students' alternative conceptions related to acid strength. Twenty years of research on secondary and college students' conceptions about acids and bases has shown that these important concepts are difficult for students to apply to qualitative problem…
