With the call for reformed teaching practices in STEM education, there is a need to spread effective teaching practices to classrooms. Affective drivers can lead an instructor to improve their teaching practices, but they are infrequently addressed or recognized. This case study followed one instructor through her General Chemistry course over a…

Chemistry students at community colleges often experience a lack of hands-on research opportunities, which can be a significant disadvantage when they transition to four-year universities. To address this, the Summer Chemistry Research Opportunities for Community College Students (SCROCCS) was established in 2022 by graduate students at the…

Holistic assessment is an evaluative approach in which assessors work backwards from an overall appraisal of work to determine the criteria relevant to individual student responses. One of the strongest proponents of this approach in higher education is Royce Sadler, whose theoretical contributions over recent decades provide a strong conceptual…

Multilingual learners face significant challenges when navigating the linguistic complexities of chemistry assessments. This study, employing the Equitable Framework for Classroom Assessment, identified these specific challenging features in general chemistry assessment items on the topics of limiting reactant and percent yield. Through in-depth,…

Study abroad attempts to prepare students to effectively work in a multi-national environment. This study compares students' experiences in a unit operations laboratory course offered in multiple modalities: at students' home university, and four- and eight-week study abroad. The results examine the impact of support on students' learning and…

The main purpose of this study is to reveal the opinions of science teacher candidates regarding the implementation of Discovery Learning-Based STEM Education in distance education with Applied Activities. The study was designed as a case study. Participants were first given basic chemistry education and introduced to the concepts of STEM,…

We present noncompetitive adsorption as "particles in a box with one sticky wall." We start with a general model that can be modeled as a simple ordinary differential equation (ODE). To verify the ODE students run a computer simulation. The ODE's solution imperfectly fits the simulation's data. This leads to the diffusion partial…

We report here on an exploratory study done with a sample of university students (N = 140) which sought to explore their understanding of the term 'coordination number', a concept encountered in the topic of transition metals chemistry, through a simple open-ended question. The findings show that the conceptual space related to the conceptions…

This study discusses the potential of the Jigsaw cooperative method in the teaching of organic chemistry. Such an approach was used in five classes with Brazilian secondary school students. Results indicate better learning regarding the development of knowledge about the nomenclature, application, and identification of functional groups at the…

Electron spin resonance (ESR) or electron paramagnetic resonance (EPR) spectroscopy is an incisive technique for the characterization of paramagnetic centers in inorganic, bioinorganic, and organic molecules and materials. These measurements are enabled with the help of paramagnetic species, such as organic free radicals and ions, electronically…

In this supplement to our second-year supercapacitor lab (Bringing Real-World Energy-Storage Research into a Second-Year Physical-Chemistry Lab Using a MnO[subscript 2]-Based Supercapacitor. "J. Chem. Educ." 2018, 95 (11), 2028-2033), we incorporate a color indicator as indirect evidence for the manganese oxide's pseudocapacitive…

The use of video productions in chemistry courses, though pedagogically beneficial, is not sufficient in and of itself. Students must also be willing to engage with these productions, especially when the videos are meant to be viewed prior to a class. Accordingly, we describe herein the implementation of two simple but effective strategies to…

In the laboratory experiment described here, students synthesize silver nanostructures (AgNS) with different shapes and sizes to elucidate the shape- and size-dependent optical properties of nanostructured materials. Students also develop understanding of some thermodynamic and kinetic aspects of the synthesis process through this experiment. In…

Polish universities offer a number of chemical competitions for high school students. One of oldest is the one organized by the Faculty of Chemistry of the Silesian University of Technology. For 27 years now this annual event has been an important tool for promoting the Faculty of Chemistry and admitting new students. It offers an opportunity to…

This 21-item survey administered at the end of first-semester General Chemistry asked students to estimate their average weekly use of course resources and rate how helpful they find various textbook and online homework features of their current textbook. During data collection, the General Chemistry textbook changed from a print version to one…
