The chemistry laboratory is an impactful platform for introducing inquiry and developing science practice skills. We designed a short lab course to introduce incremental levels of inquiry, also to interconnect and integrate different domains of chemistry. Indigo dye was the central theme of this short course wherein students synthesized indigo,…

Acid-base titration concepts and experiments are ubiquitous, yet challenging, aspects of the general chemistry curriculum. Most general chemistry courses include at least one acid-base titration laboratory experiment, though the focus is often on determining the concentration, pK[subscript a], or molar mass of an analyte rather than on the details…

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…

Inquiry-based laboratories were implemented into a General Chemistry Laboratory sequence, and the impact of these exercises on students' experimental design skills was assessed using a four-part assessment developed for this study. This assessment contained a multiple-choice section, a section asking students to explain their reasoning behind a…

Advancements in technology have led to significant changes in the workforce and created a demand for expertise in science, technology, engineering, and mathematics (STEM). In response, curricula have evolved to emphasize essential skills such as critical thinking and communication to prepare students for STEM-based careers. To this end,…

We designed a collaborative course-based undergraduate research experience (CURE) between an Analytical Chemistry course and an Environmental Toxicology course to engage students in a research project that cannot rely on one discipline alone. This study reports on 47 students' self-reported experiences with the course outcomes and their opinions…

This project is conducted by students during the second semester of their second year in our educational institution. This project constitutes an initiation into research and allows a broadening of knowledge, a development in autonomy, organization, team work, and initiative. It helps prepare the student-engineer for an internship in industry. The…
