A time- and cost-effective strategy aimed at increasing awareness of diversity, equity, inclusion, respect (DEIR), safety, and other issues within a typical graduate program is described. Using a brief portion of time (up to [approximately]10 min) at the commencement of each weekly departmental colloquium event, graduate students under faculty…

Recently I took a walk through the physics demonstration room at Kenyon College, where I first started teaching in 1964. On an upper shelf was the little home-built apparatus in Fig. 1. This was used for one of two short single-concept films that I made in the 1970s. Both "The Magnus Effect" and "Optical Barrier Penetration"…

A solenoid is a coil wound many times on a cylinder of length greater than its diameter. Solenoids are mainly used as electromagnets, because a magnetic field is formed when current flows through a solenoid. The solenoid described in secondary school and university textbooks is a single-layered solenoid. Further, textbooks and papers focusing on…

The purpose of this study was to assess and describe the status of program evaluation within the National Science Foundation's (NSF) Research Experiences for Undergraduates (REU) sites. The National Science Foundation's REU program supports thousands of undergraduates annually in hands-on, immersive research experiences under the mentorship of…

An undergraduate laboratory experiment has been developed for the synthesis of a reactive cross-linker that is useful in various highly visual demonstrations of organic reactivity, click chemistry, and biobased polymer synthesis. A triazolinedione-based cross-linker, which is known as a useful reagent for click chemistry, can be obtained from…

Advances in the field of Mind, Brain, and Education (MBE) have been limited by a fundamental separation between university-based neuroscience laboratories and school communities, constraining the field's ability to collaboratively devise research studies germane to child development. This commentary explores the assertion that the persistent…

This study focuses on students who are registered for the University of Pretoria's academic development programme, the Four-year Programme (FYP). The programme was introduced as a gateway for students who are under-prepared but have the potential to succeed. This programme helps them to then continue their studies in mainstream science programmes.…

Removing the pollutants from various wastewater is crucial to the environment, ecology, and humans. However, the pollutants are generally removed by chemical decomposition, which not only consumes a lot of energy but also produces carbon emissions. Electrochemical flocculation is effective to extract pollutant molecules and heavy ions from…

This dissertation consists of two distinct bodies of work. The first leverages a unique aspect of fire ant biology to investigate a potential role for a supergene in genetic assimilation. A supergene refers to a chromosome structural rearrangement, such as an inversion, that regulates the production of an alternative phenotype within a species. In…

Undergraduate STEM students have limited opportunities to apply course-acquired knowledge in the community. Experiential learning opportunities that connect students with community partners offer one impactful way to apply course learning to communities within and beyond the university. While studies have established the value of experiential…

This qualitative study delves into the intricate landscape of general chemistry students' study strategy decision-making processes, examining the guiding factors that shape their choices. Past work in chemistry education has shown that students' study behaviors are dynamic in nature. Employing self-regulation theory, the study aims to provide a…

Background: Achievement goal theory is a popular motivational theory within education and psychology, with several review papers summarizing the extensive work done in these fields. Although reviews exist in these specific fields, none exists within science, technology, engineering, and mathematics (STEM) education. This is a considerable gap in…

In analytical chemistry, discussing different method sand techniques of analysis is essential to promote critical thinking and reasoning. Analytical courses in the chemist, pharmacist, and biochemist curricula represent the opportunity to study concepts such as experimental design, sampling, development, and optimization of protocols, data…

The education science (or pedagogy based on scientific principles) of the learning of spectroscopy analysis in terms of critical thinking was examined in a community college setting with high school outreach and senor college transfer students enrolling in courses and/or projects. The most important discovery of science in the 20th Century was the…
