Photo-oxidation is one of the main causes of oxidative deterioration in food. Understanding of the mechanisms of photo-oxidation is essential for food science students when pursuing careers in food safety and quality assurance. However, few food chemistry laboratories emphasize photo-oxidation. Thus, we develop a laboratory activity that trains…

Problem-based learning (PBL) is an acclaimed educational concept for laboratory teaching in chemistry, which significantly affects learner motivation. A central aim of PBL is to overcome educational problems with "cook-book" laboratories. For example, when students receive experimental instructions and apply the instructions similar to…

Increasing access to undergraduate research is critical in efforts to retain students pursuing careers in STEM. Alternatives to traditional research positions, such as course based undergraduate research experiences (CUREs), have played important roles in engaging more undergraduates in research. However, these opportunities are only a subset of…

For the present lab demonstration, we have developed fluorescent indicators to detect the end point in microscale redox titration of ferrous ions in permanganometry, cerimetry, and dichrometry. Microscale redox titrations were carried out effectively in micromolar(µM) concentrations and semi-microvolumes of the analytes. At the end point,…

The COVID-19 pandemic of Spring 2020 saw chemistry instructors across the globe working to deliver traditional hands-on laboratory learning within a remote learning environment. This study focused on the student perspective on remote laboratory delivery models across 13 Fall 2020 chemistry courses with students from all four years of undergraduate…

The correct use of micropipettes has been investigated in an undergraduate, introductory lab experiment intended for chemistry and biology majors. This lab experiment involves the use of micropipettes for accurately mixing, transferring, and applying a specific amount of dye to a cotton bandana. The data resulting from this experiment is a color…

A novel undergraduate analytical chemistry experiment involving the identification and quantification of linalool in essential oils was developed. The experiment uses the internal standard method with headspace solid phase microextraction (SPME) and gas chromatography--mass spectrometry (GC-MS). This method is applicable to any linalool-containing…

Formative assessment is a crucial element of teaching and learning which allows students to identify challenging course concepts and enables educators to assess the effectiveness of their teaching strategies. Web-based student response systems have gained popularity for their ability to provide instant feedback to students and instructors while…

A computational laboratory experiment is carried out to investigate the size-, geometry-, and chemistry-dependent properties of small molecules known as polycyclic aromatic hydrocarbons (PAHs) at the Facultad de Ingeniería (Universidad Nacional de La Plata, UNLP), Buenos Aires, Argentina. This computational research was adapted for upper-division…

Organic chemistry courses enroll students from many majors with diverse interests. Although instructors may strive to appeal to these interests by relating course content to real life, it is challenging to intrinsically appeal to students at the personal level, particularly in high enrollment courses like organic chemistry. When students identify…

Lecture capture videos were explored as beyond the classroom course materials in upper-level descriptive inorganic chemistry courses during Fall 2017, Fall 2018, and Fall 2020 semesters. Page views data from the learning management system (LMS) Canvas site served as a proxy for course content usage materials such as lecture capture videos. There…

A required first-year laboratory course was overhauled into a semester-long biosciences course-based undergraduate research experience (BioCURE) with a goal of enhancing learning and improving retention. Student attributes and outcomes were continually monitored by the University's Institutional Research office over a 5-year period and compared…

Quantitative metrics are widely employed to determine the probability of an applicant succeeding in a specific program of interest, ranging from undergraduate or graduate admissions to fellowships. The admissions office at the United States Military Academy at West Point uses an internal college entrance examination rank (CEER) assessment…

In order to fully appreciate the interdisciplinary nature of energy resources, there is a need to understand pertinent issues from other viewpoints besides a purely chemistry perspective. In this paper, the teaching of cost-benefit analysis (CBA) and business databases as part of CM4282: Energy Resources at the Department of Chemistry, National…

Inquiry- and context-based learning (IBL and CBL, respectively) can lead to improved student outcomes, including increased motivation and interest, the development of critical thinking skills, and improved assessment results. This study outlines the application of IBL research projects in third-year university Environmental Chemistry and…
