Reed, Jessica J.; Villafan~e, Sachel M.; Raker, Jeffrey R.; Holme, Thomas A.; Murphy, Kristen L. – Journal of Chemical Education, 2017
General chemistry courses are often the foundation for the study of other science disciplines and upper-level chemistry concepts. Students who take introductory chemistry courses are more often from health and science-related fields than chemistry. As such, the content taught and assessed in general chemistry courses is envisioned as building…

Stowe, Ryan L.; Cooper, Melanie M. – Journal of Chemical Education, 2017
Organic chemistry is often promoted as a course designed to cultivate skill in scientific "ways of thinking." Expert organic chemists perceive their field as one in which plausible answers to complex questions are arrived at through analytical thought processes. They draw analogy between problem solving in organic chemistry and diagnosis…

Towns, Marcy H. – Journal of Chemical Education, 2014
Chemistry faculty members are highly skilled in obtaining, analyzing, and interpreting physical measurements, but often they are less skilled in measuring student learning. This work provides guidance for chemistry faculty from the research literature on multiple-choice item development in chemistry. Areas covered include content, stem, and…

Holme, Thomas – Journal of Chemical Education, 2014
Two different versions of "big ideas" rooted content maps have recently been published for general chemistry. As embodied in the content outline from the College Board, one of these maps is designed to guide curriculum development and testing for advanced placement (AP) chemistry. The Anchoring Concepts Content Map for general chemistry…

Raker, Jeffrey R.; Holme, Thomas A. – Journal of Chemical Education, 2013
Standardized examinations, such as those developed and disseminated by the ACS Examinations Institute, are artifacts of the teaching of a course and over time may provide a historical perspective on how curricula have changed and evolved. This study investigated changes in organic chemistry curricula across a 60-year period by evaluating 18 ACS…

Arjoon, Janelle A.; Xu, Xiaoying; Lewis, Jennifer E. – Journal of Chemical Education, 2013
Many of the instruments developed for research use by the chemistry education community are relatively new. Because psychometric evidence dictates the validity of interpretations made from test scores, gathering and reporting validity and reliability evidence is of utmost importance. Therefore, the purpose of this study was to investigate what…
