In this article, we discuss the replication of a forgotten chemical instrument in the context of undergraduate chemistry education. Together with students, we have attempted to replicate an eighteenth century "eudiometrical" procedure. Eudiometry was the practice of measuring the "goodness" of the air by looking at the volume…

NMR prediction using ChemDoodle, NMR calculation with Gaussian, and hands-on data collection using a benchtop NMR spectrometer were explored to assess their synergistic capacity in teaching NMR to organic chemistry students. Nine molecules representing functional groups commonly encountered in undergraduate organic chemistry were selected. Spectra…

Paal--Knorr reactions are a classical method for synthesizing pyrroles, using 1,4-dicarbonyl compound and amine as reactants. It has the characteristics of green chemistry, as only two molecules of water are lost. In this teaching and learning experiment, 2,5-hexanedione and 4-"tert"-butylaniline were used to synthesize…

Science educators face significant challenges in preparing learners with the skills and knowledge necessary for 21st-century functional scientific literacy. This stems from high expectations of students and a growing demand for them to apply their learning to complex issues with political, social, environmental, and economic dimensions. The…

Removing the pollutants from various wastewater is crucial to the environment, ecology, and humans. However, the pollutants are generally removed by chemical decomposition, which not only consumes a lot of energy but also produces carbon emissions. Electrochemical flocculation is effective to extract pollutant molecules and heavy ions from…

Interactive digital technologies are playing an increasingly important part in education for enhancing collaborative learning processes and improving engagement. Social annotation (SA) tools and collaborative platforms are an innovative way to involve students to give and take feedback, annotate, and brainstorm on complex topics in science,…

This paper outlines a comprehensive teaching laboratory course program that centers on titration analysis, a timeless and essential technique in analytical chemistry spanning various disciplines, such as environmental science, medicine, and industry. In these fields, titration analysis is paramount for determining the concentrations of substances…

Formative assessment is highly beneficial for student motivation and achievement, but in undergraduate courses, especially large introductory life sciences courses, it may be difficult for instructors to gather the evidence necessary for quality formative assessment. Undergraduate teaching and learning assistants (UTLAs) can help to implement…

The teaching of laboratory skills to undergraduate students is central to all experimental sciences. In this setting, students must understand the experimental procedures as well as the fundamental principle(s) being demonstrated, all while learning within a limited time. Other limiting factors include access to equipment and reagents, resulting…

Micropaleontology is a critical tool for determining the ages of geologic records, reconstructing ancient environments, and monitoring modern ecosystem health. However, most students are not exposed to micropaleontology in their college coursework. To enable non-expert instructors to integrate microfossil identification training in their…

Teaching the three-dimensional structure of saccharides has consistently been a challenging aspect of organic chemistry courses, impeding students' ability to grasp more advanced topics in biochemistry and food chemistry. In this article, we designed and developed a novel d-glucopyranose model using 3D printing technology for the first time. This…

Conflict-reducing practices during evolution instruction have been recommended to increase students' perceived compatibility between evolution and religion, increase evolution acceptance, and decrease stereotypes about religious students in science. However, the efficacy of these practices has not been demonstrated in a randomized controlled…

Traditional lab courses separate lectures from lab work, whereas integrated lab-lecture courses (also known as studio courses) combine both in a single session under one instructor. Previous studies suggest that integrated lab-lecture courses may have the potential to enhance the learning experience for introductory-level students. In this…

The scope of this preliminary study revolves around investigating the effectiveness of experiential learning in upper-year science laboratory courses in a post-pandemic era. In this study we have explored two key questions: 1. Can experiential learning facilitate independent inquiry in an upper-year undergraduate laboratory in a post-pandemic era?…

The chemical experiment in this study is specifically created for undergraduate students studying energy and the environment. The target of the experiment is for students to comprehend the deactivation mechanism of the Ce/TiO[subscript 2] catalyst by oxides of phosphorus through practical experiments and enhance their knowledge of environmental…
