Hermanns, Jolanda; Keller, David – Journal of Chemical Education, 2021
In this paper, we describe a study on tasks following the construct of school-related content knowledge. We know from previous studies that such tasks were rated by the preservice chemistry teachers as important for their future profession. Those studies were conducted in a traditional course on organic chemistry which was organized around…

Lang, Vanessa; Eckert, Christine; Perels, Franziska; Kay, Christopher W. M.; Seibert, Johann – Education Sciences, 2021
Models are essential in science and therefore in scientific literacy. Therefore, pupils need to attain competency in the appropriate use of models. This so-called model--methodical competence distinguishes between model competence (the conceptual part) and modelling competence (the procedural part), wherefrom a definition follows a general…

Sansom, Rebecca L.; Clinton-Lisell, Virginia; Fischer, Lane – Journal of Chemical Education, 2021
General chemistry is a gateway course for most STEM majors, so student success is a priority for chemistry faculty. Providing quality information resources for students, including textbooks, is one way that instructors can support student learning. However, these resources can be prohibitively expensive for some students, causing them to opt out…

Duerden, Amanda; Moon, Nicole; Grubbs, G. S., II – Journal of Chemical Education, 2021
Few laboratory exercises exist that introduce undergraduate students to both the concepts and instrumentation used in rotational spectroscopy. Because of this gap in undergraduate laboratory training, a teaching laboratory for the pure rotational spectroscopy of benzonitrile has been developed and reported. Owing to benzonitrile's recent discovery…

For some professionally, vocationally, or technically oriented careers, curricula delivered in higher education establishments may focus on teaching material related to a single discipline. By contrast, multidisciplinary, interdisciplinary, and transdisciplinary teaching(MITT) results in improved affective and cognitive learning and critical…

Bopegedera, A. M. R. P. – Journal of Chemical Education, 2021
"Chemistry in the Public Library" is an outreach event that has fostered a continuing, long-standing partnership between The Evergreen State College in Olympia, Washington (a public, liberal arts college), the Olympia Timberland Regional Library (the local public library), and the community. It started as a National Chemistry Week event…

Quin~ones, Rosalynn; Moreno, Sara; Shoup, Deben; Klein, Mieke; Westfall, Tamara D.; Damai, Aakriti – Journal of Chemical Education, 2021
With the advancements in broad-spectrum sunscreens and the recent bans on benzene-based sunscreens due to their environmental toxicity, there has been a push toward broad-spectrum sunscreens containing in organic active ingredients. In this study, a procedure was developed to analyze the particle size and size distribution of inorganic active…

Busby, Brittany D.; Harshman, Jordan – Chemistry Education Research and Practice, 2021
The goal of graduate education has consistently been to produce independent scientists who can advance the knowledge of their fields, which has led to a series of staple elements in graduate components (i.e. research, courses, seminars, etc.) However, criticisms of graduate education in chemistry have been raised, stating that the current…

Gupte, Trisha; Watts, Field M.; Schmidt-McCormack, Jennifer A.; Zaimi, Ina; Gere, Anne Ruggles; Shultz, Ginger V. – Chemistry Education Research and Practice, 2021
Teaching organic chemistry requires supporting learning strategies that meaningfully engage students with the challenging concepts and advanced problem-solving skills needed to be successful. Such meaningful learning experiences should encourage students to actively choose to incorporate new concepts into their existing knowledge frameworks by…

Reid, Scott A.; MacBride, Laura; Nobile, Llanie; Fiedler, Adam T.; Gardinier, James R. – Chemistry Education Research and Practice, 2021
General chemistry courses are key gateways for many Science, Technology, Engineering, and Mathematics (STEM) majors. Here, we report on the implementation and evaluation of an adaptive, ALEKS-based online preparatory module (PM) for general chemistry. The module was made available in Summer 2018 at no cost to all students entering any section of…

Akinyemi, Olutosin Solomon; Mavhunga, Elizabeth – Chemistry Education Research and Practice, 2021
This paper reports on the relationship between the pre-service teachers' enacted Topic Specific Pedagogical Content Knowledge (eTSPCK) observable in the classroom teaching of Organic Chemistry and learner achievement in the topic. The study employed a mixed-methods research design with a sample of 17 pre-service teachers (PSTs). The PSTs were…

Zhang, Hongyang; Wink, Donald J. – Journal of Chemical Education, 2021
This paper uses evidence-centered assessment design (ECD) to structure and analyze a laboratory activity where students collect and represent titration curve data to determine acid strength in terms of molarity and dissociation constant. Following principles of multidimensional learning, the activity prompts students to demonstrate knowledge of…

Donnelly, Julie; Winkelmann, Kurt – Journal of Chemical Education, 2021
Students' negative perceptions of physical chemistry courses are well-known and are likely impacting their learning and performance in this upper-division course for majors. The syllabus can be the first interaction students have with a course and instructor and can be central to the expectations student set for the learning experience. While…
