Thibaut, Dylan; Schroeder, Kersten – Journal of Effective Teaching in Higher Education, 2023
As COVID-19 restrictions are removed, instructors are faced with two questions: should the course be taught online, via mixed-mode, or through traditional methods, and what effect did online instruction have on students in the course in regards regarding enrolled across eight semesters of metabolism courses using traditional, mixed-mode, and…

[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] Uncertainty is an important concept in physics laboratory instruction. However, little work has examined how students reason about uncertainty beyond the introductory (intro) level. In this work we aimed to compare intro and beyond-intro…

Kreager, B. Z.; LaDue, N. D.; Shipley, T. F. – Journal of Geoscience Education, 2023
Sequence stratigraphic and Wheeler diagram interpretations require a strong combination of conceptual understanding and diagram reasoning skills. Students are generally exposed to the foundational concepts within sequence stratigraphy (relative sea level, eustasy, base level, and accommodation) in a variety of courses along their degree path,…

Mizrap Bulunuz; Betül Kuralay – Online Submission, 2023
Mole, molar mass and the Avogadro number are used constantly to measure the amount of substance in chemical changes. However, students have difficulty in understanding these concepts because they are not familiar with measuring very small amounts of matter that cannot be seen and weighed in daily life, like atoms. The mole concept was developed to…

Two-tiered assessment structures with paired content and confidence items are frequently used within chemistry assessments to stimulate and measure students' metacognition. The confidence judgment is designed to promote students' reflection on their application of content knowledge and can be characterized as calibrated or miscalibrated based on…

Corinna Mo¨nch; Silvija Markic – Journal of Chemical Education, 2023
Language, and thus scientific language, is essential for chemistry teaching and learning. To be able to successfully teach the scientific language of chemistry, the Chemish, (prospective) chemistry teachers need to possess pedagogical scientific language knowledge (PSLK).Thus, teacher preparation needs to focus explicitly on Chemish and its…

Eleven different laboratory experiments were designed and executed throughout a semester to provide a meaningful research experience for 23 undergraduate biochemistry majors at UTSA. The topic of the semester was based on the idea of exploring new aspects to enhance our understanding of how the human body uses cytochrome P450 enzymes to metabolize…

The electrolysis of water to produce hydrogen is a critical step in many green chemistry processes. The key to the efficiency of water electrolysis is the synthesis of an appropriate electrocatalyst. Three-dimensional (3D) printing is an increasingly important part of many industrial processes. In this study, we propose an efficient laboratory…

The "maker" movement is gaining widespread attention, especially in the field of laboratory education. Here we have built a low-cost, "do-it-yourself", open-source thermal conductivity cell detector (TCD) for chemical laboratory analysis, which is assembled from thermal conductivity gas sensor elements and 3D-printed flow cell…

A set of core concepts ("big ideas") integral to the discipline of physiology are important for students to understand and demonstrate their capacity to apply. We found poor alignment of learning outcomes in programs with physiology majors (or equivalent) from 17 Australian universities and the 15 core concepts developed by a team in the…

A class of 18 students attending the last year of an Italian high school was divided into groups and performed the extraction of pigments contained in hibiscus tea. Each group worked at a different temperature and carried out multiple extractions using distilled water as a solvent. By means of UV-vis spectroscopy it was possible to determine the…

Chemistry topics are ubiquitous in healthcare diagnostics as well as health professions undergraduate curricula. However, there are limited correlations between chemistry and healthcare made in textbooks or template lecture materials. For undergraduate nursing students (BSN) enrolled in a Chemistry for Health Professions course, the author (and…
