Student engagement in evidence-based argumentation plays a central role in science education. These skills can be developed when identifying organic molecules from the spectroscopic data. Molecular structural analysis fosters deep procedural knowledge, as it involves (i) flexibly applying a set of procedures to extract information from spectra,…

A qualitative sugar identification laboratory was adapted from a hands-on experiment to a virtual "choose your own adventure" experience where students select virtual experiments to conduct on samples of known and unknown carbohydrates. Students select positive and negative controls for each qualitative test and compare results from the…

A problem-solving experiment is a learning activity that uses experimental design to solve an authentic problem. It combines two evidence-based teaching strategies: problem-based learning and inquiry-based learning. The use of problem-based learning and scientific inquiry as an effective pedagogical tool in the science classroom has been well…

Ultraviolet (UV)-visible (Vis) spectroscopy is widely used in all modern laboratories as a routine method of analysis. The monitoring of chemical reactions in an aqueous solution involving a gas product is a demanding task but particularly for oscillatory reactions which are obtainable in a narrow concentration range. In this work, the…

In case-based learning, students develop and apply course knowledge to solve tangible and "real life" problems. This practice can enhance student motivation and engagement in the analytical laboratory. In this application of case-based learning students analyze commercially available oils for CBD content. In the state of Texas anyone can…

Herein we propose the implementation of an "escape room" activity to reinforce chemistry-related concepts for students of the Bachelor of Arts and Fashion. In this work, a combined online and offline activity is developed, easily adaptable to different environments. The online activity consists of 5 blocks of multiple-quiz questions…

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…

The quest in the "Mirror Mirror on the Wall, Which Chiral Drug Is the Fairest of Them All?" escape room activity was to find an enantiomer drug that cures a "sleeping sickness". Based loosely on the story of Snow White, first-year pharmacy student pairs had 50 min to solve gamified stereochemistry quizzes (tasks 1-4), collect…

Written examinations for laboratory courses fall short in testing students' technical skills, problem-solving abilities, and execution of experimental design. This has led to practical examinations growing in popularity, but examples for senior-level students remain scarce. Senior organic chemistry students are gearing toward independence to…

An undergraduate-level Computational Chemistry project was incorporated initially into a Physical Chemistry course and then into the laboratory curriculum in the subsequent application. Before the introduction of the project, the lectures covered quantum chemistry, spectroscopy, and kinetics while simultaneously including computational chemistry…

Transforming the chemistry curriculum to an interdisciplinary perspective is essential for preparing students to meet interdisciplinary career demands and to brace themselves for the challenges of complex environmental and health issues. The study introduces four interdisciplinary electrochemistry STEM-lab activities as an alternative to the…

An online virtual escape-room game was created using the Google Forms survey app for an undergraduate chemistry lab class. Zoom video conferencing service was used to make the activity a collaborative learning experience. The theme was an escape from an abandoned chocolate factory, and the students solved problems to move to the next section or…

Summative lab assessments probe student mastery over concepts, but conventional ones often result in decreased student engagement and confidence. If conventional summative lab assessments are replaced by accessible gamified evaluations, such as online escape rooms, this leads to improved student engagement and confidence. In this work, we adapted…

Scientists understand that no result is more important than the welfare of the investigators and the people around them. Safety culture is an integral part of industrial and academic jobs; however, safety training has only recently been added to chemistry classroom and laboratories. Chemistry laboratories expose workers to a variety of hazards,…

Based on quantitative survey data collected from an inquiry-based general chemistry laboratory course, the current study used marginal models to evaluate changes in students' teamwork and problem-solving skills, attitudes to teamwork, and willingness to explore new issues before and after the course. The results suggest that introductory-level…
