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…

Angela L. Mahaffey – Journal of Chemical Education, 2023
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…

This study investigates the utilization of a lightboard in flipped classrooms for General Chemistry and examines its impact on the measurable student outcomes. The flipped classroom model has garnered attention as a potentially transformative approach to teaching and learning, particularly in science and math courses. A lightboard video can…

Choi, Yunhee; Lee, Hyunju – Asia-Pacific Science Education, 2021
This study aimed to examine the effects of a research-based SSI program on fostering students' understanding of issues and their willingness to act. Twenty-five middle school students voluntarily participated in the program on the issue of artificial food additives over 6 months. The data were collected by means of interviews with the students,…

The current study examines the progress of 8th-grade student drawings and written explanations of chemical phenomenon, subsequent to being involved in an instructional strategy that explicitly involves drawing as a supportive toll to construct scientific explanations. Additionally, the study examines the association between the representation of…

Nixon, Ryan S.; Campbell, Benjamin K. – School Science and Mathematics, 2021
Teachers make many important decisions about instruction during the process of planning. While educational researchers have extensively explored teacher planning, this research has largely neglected the ways teachers attend to subject matter while planning. We first explore ways a sample of 13 experienced secondary biology teachers attend to…

Despite advances in software development, symmetry-related topics are among the most important yet confusing concepts in crystallography training for chemistry students who routinely use small-molecule crystallography in their scientific study. The case-based learning approach is very effective in stimulating students' interests in self-exploring…

Mathayas, Nitasha; Brown, David E.; Lindgren, Robb – Journal of Research in Science Teaching, 2021
Constructing causal mechanistic explanations of observable phenomena is a key science practice that is often challenging for students as most mechanisms involve interactions of unobservable entities and activities. In this study, we examined how gesturing with a computer simulation that depicts the molecular mechanism of thermal conduction…
