This review examines the evolution of tertiary undergraduate chemistry teaching from 2019 to 2023, including in response to the global pandemic's impact on teaching and learning methods and whether those adaptations have persisted. The authors assessed the current educational landscape against standards set by leading accreditation bodies, the…

This study investigated the association between students' perceptions of digital accessibility and competence, self-efficacy for self-directed learning (SDL) and their self-rated final grades in the virtual laboratory course during the COVID-19 outbreak. Data were collected from 217 engineering students enrolled in four virtual undergraduate…

Past research has growingly shown importance of teacher candidates' ability to connect theory and practice for applying what they have acquired in coursework into practice. This study examined 23 mathematics teacher candidates' (TCs) ability to link coursework and online mathematics teaching field experiences in a mathematics teacher education…

The laboratory protocol presented here takes about 3 hours to perform and investigates protein and lipid interactions. Students first purify His6-tagged human apolipoprotein A-I (apoA-I) with Ni-NTA affinity resin in a simple batch protocol and prepare multilamellar vesicles (MLV) from pre-dried phospholipid films. When apoA-I is added to the MLV,…

Manu Prakash, the developer of the foldscope microscope reported on in this paper, stated that it is important to use tools that can support open-ended inquiry in the classroom, without dumbing down those tools. Scientific equipment in the school laboratory is often very expensive and only available to those who can afford it. "Frugal…

The mission of most writing centers is to cultivate effective and independent writers. However, in sessions with students from culturally and linguistically diverse backgrounds, tutors tend to make direct edits on their writing products despite writing center policies that discourage such practices and encourage process-oriented writing…

This theoretical paper defines and explores the concepts of transductive links and transductive chains, as part of the theoretical framework of social semiotics. Social semiotics stems from the multimodal framework, which provides a theoretical perspective, constructs, and a language to describe a shift of semiotic material within or between…

Enzyme-Linked Immunosorbent Assay (ELISA) is a versatile and widely used technique to detect and quantify small molecules in various clinical and analytical applications. It is also an effective tool for demonstrating the specificity between antibody and antigen to students across diverse disciplines. However, undergraduate laboratories often face…

Data collected in many biology laboratory classes are on ratio or interval scales where the size interval between adjacent units on the scale is constant, which is a critical requirement for analysis with parametric statistics such as t-tests or analysis of variance. In other cases, such as ratings of disease or behavior, data are collected on…

The recent COVID-19 pandemic has led to widespread lock-down strategies that force universities to perform all educational activities remotely. In this context, laboratory lessons pose a significant challenge. Here, I present an on-line tool that simulates the kinetics of chemical reactions. Enzymatic mechanisms can be easily modeled and followed…

The science laboratory is a politically entrenched space where complex power relations interplay while social agents learn about the rules and routines to ensure safety, precision and reproducibility in research work. This paper presents a case study of two Singaporean students undergoing apprenticeship in a 3-year school-based School Scientist…

A simple apparatus consisting of a plastic syringe coupled with a U-tube has been constructed. This setup is filled with water to trap air in one arm of the U-tube. A change in the volume of the enclosed air causes a change in its pressure that is indicated by the difference in the water levels. Boyle's law is shown by a linear relation between…

Properly made solutions are critical to the scientific method. However, in various laboratories and collaborative environments, we have noticed a lack of proper technique for making solutions. Instead of measuring the moles of solute then filling up to the needed volume with solvent, we observed many individuals would measure the moles of solute…

Simulation training has become increasingly relevant in the educational curriculum of surgical trainees. The types of simulation models used, goals of simulation training, and an objective assessment of its utility and effectiveness are highly variable. The role and effectiveness of cadaveric simulation in cardiothoracic surgical training has not…

Instructive, inexpensive, and environmentally friendly laboratory syntheses of two highly luminescent copper(I) complexes CuI(PPh[subcript 3])[subscript 2](py[superscript R]) (py[superscript R] = pyridine, 4-cyanopyridine) are described for second-year/upper-division undergraduate inorganic chemistry students. Both complexes exhibit bright…
