Experiments involving electrochemical cells are of great pedagogical value for learners of introductory chemistry. This paper discusses an improved experimental kit made from a 24-well cell culture plate and a 3D-printed scaffold. The current design focuses not only on the accuracy of the result but also on the intuitiveness of the wiring work and…

Over the course of the COVID-19 pandemic, school students suffered from a reduction in opportunities to connect with higher education institutions, meet scientific role models in person, discuss scientific career options, and carry out hands-on practical laboratory activities. Current Chemistry Investigators (CCI) is a successful…

A comparative study on the performance and on the perception of two groups of students involved in a peer review activity on the writing of chemical laboratory reports is reported. The first group participated in a compulsory activity, while the second one participated on a voluntary basis. This study was aimed at determining whether the overall…

Teaching through experiments has always been an indispensable teaching method in chemistry and other STEM disciplines. Letting more students have access to experiments at the frontier of scientific research is essential to stimulating students' interest in chemistry. With the advancement of computer technology, virtual simulation experiments…

The perception of 3D features from 2D representations depend on their number of salient features, recognizable canonical axes, and orientations. Informed by form-perception literature, we proposed a hexagonal prism as an external reference frame to identify positions of elements in relation to each other and the observer when studying Diels-Alder…

Alternative teaching methodologies are required for grade-9 students diagnosed with difficulties learning chemistry. This study examines the progress made in learning atomic structure by 11 Spanish Students Diagnosed with Learning Difficulties (SDLD, experimental group), including those with poor academic performance, specific learning…

To facilitate the chemistry education community in locating and evaluating published assessment instruments, the Chemistry Instrument Review and Assessment Library (CHIRAL) encompasses a number of resources. First and foremost, CHIRAL contains a catalog of over 500 assessment instruments that is easily searchable, allowing for the identification…

The COVID-19 outbreak represented a remarkable challenge in universities and colleges since it forced the transition from a face-to-face model in classrooms and laboratories to a remote, online model using computers, tablets, and cell phones. In Mexico and other Latin American countries, the return to educational activities was a slow-paced…

The aroma volatile compounds in tomatoes are strongly linked to taste and flavor. Commercial tomato varieties, however, generally lack flavor. Tomato breeding programs have therefore started to focus on increasing the flavor-enhancing volatiles, which can be more easily altered than the sugar content. Analytical efforts that identify key flavor…

The COVID-19 pandemic has highlighted many challenges undergraduate students face including their ability to manage stress. Poor stress management can contribute to poor academic performance and health outcomes; better wellness habits and stress reduction go hand-in-hand, as improved wellness habits reduce overall stress and expand positive stress…

Course-based Undergraduate Research Experiences (CUREs) are a pedagogical model where a traditional undergraduate course is transformed into a research-intensive course, offering an alternative pathway to research for undergraduate students. Given the novel learning context of CUREs, there is a need to understand the learning that occurs and the…

A Maker-oriented experimental course in general chemistry has been created by using digital tools, such as a computer, a pressure sensor, and data processing software, in combination with a new multiple expansion method and laboratory equipment to determine the vapor pressure precisely. In this Maker chemistry experiment, the pressure sensor…

This report offers technical guidance and encouragement for any instructor or department looking to produce valuable, high-quality Lightboard teaching videos under space and budget constraints. Lightboards were introduced in a chemical education setting around 2015 as a presentation setup that allowed the presenter to speak face-to-face to their…

Given the growing prevalence of computational methods in chemistry, it is essential that undergraduate curricula introduce students to these approaches. One such area is the application of machine learning (ML) techniques to chemistry. Here we describe a new activity that applies ML regression analysis to the common physical chemistry laboratory…

Chemistry education research demonstrates the value of open-ended writing tasks, such as writing-to-learn (WTL) assignments, for supporting students' learning with topics including reasoning about reaction mechanisms. The emergence of generative artificial intelligence (AI)technology, such as chatbots ChatGPT and Bard, raises concerns regarding…
