The mass-approach in higher education promotes the broadening of students' number and diversity therefore the question about the young people's readiness to adapt to studies becomes more and more topical. Students who enrol in the natural science faculties of the University of Latvia (UL) are motivated and have high assessment in biology and…

The American Association for the Advancement of Science (AAAS) has outlined four themes that define science literacy; these are systems, models, constancy and change, and scale. More recently, the National Research Council has released the framework for K-12 science education that includes "Scale, Proportion, and Quantity". Scale…

Flavor plays a crucial role and is the most important aspect of foods and beverages. [Beta]-Ionone is a common flavor compound with a characteristic violet-like odor. An undergraduate flavor compounds chemistry laboratory that provides preparation and characterization of the flavor compound inclusion complex between…

College physics textbooks (algebra based) tend to shy away from topics that are usually thought to require calculus. I suspect that most students are just as happy to avoid these topics. Occasionally, I encounter students who are not so easily satisfied, and have found it useful to maintain a storehouse of non-calculus solutions for some common…

One theme that both the American Association for the Advancement of Science (AAAS) and the National Research Council (NRC) agree pervades any science course (and specifically chemistry) is scale. Despite the fact that scale concepts and skills are at the core of a student's scientific literacy, scale or the skills related to understanding quantity…

Gold is an increasingly prominent transition metal in organic synthesis. The air-stable, water-insensitive cationic gold(I) catalysts enable varieties of synthetic transformations with a simple reaction setup. However, this increased importance has not coincided with an increase in the application of gold in second-year organic chemistry courses.…

Molecular orbital diagrams are commonly taught and used for describing chemical bonding chemistry courses including courses at the college level. Misconceptions that occur when students construct and/or use these diagrams are difficult to anticipate, diminish the diagram utility, and limit student learning. In this exploratory study, a combination…

Stepped supporting tools were developed and used in the university seminar Organic Chemistry taken by nonmajor chemistry students, which supported self-regulated learning. These supporting tools were also used for accompanying homework, which included a QR code that led to additional supporting tools. The application of stepped supporting tools in…

In this experiment, students are asked to conduct a catalytic cross-metathesis experiment and compare this reaction to the Wittig reaction within the confines of green chemistry. Students synthesize stilbene from styrene using Grubbs second-generation catalyst. Products can be minimally characterized by IR spectroscopy and melting point, but using…

4-"tert"-Butylcyclohexanol is rapidly converted to 4-"tert"-butylcyclohexanone with swimming pool bleach in a homogeneous reaction at room temperature. This process introduces students to a heterocyclic compound not normally discussed in the introductory course and has significant advantages over standard procedures using…

The relationship between chemical structure and physical and chemical properties is essential to chemistry. Studies have shown that students have difficulty using structural representations to predict properties, which is not surprising because of the sequence of inferences that are required for sense-making. However, obtaining a nuanced model of…

There is a need for more courses that directly address the role business plays in the development of new products and technology. This is particularly true in the areas of green and sustainable chemistry where altruism is often not enough to overcome perceived increased cost. Chemistry of Sustainable Products is an undergraduate chemistry course…

The implementation of environmentally friendly, solvent-free mechanochemical synthesis in an undergraduate chemistry teaching laboratory is described. As a model reaction, the experiment addresses the catalytic mechanochemical synthesis of a small library of sulfonylureas, including a known active pharmaceutical ingredient, tolbutamide. The…

Citizens in all roles need to be able to construct causal explanations of scientific phenomena and engage in coherent argumentation, supported by evidence and sound reasoning. These skills are needed in many contexts, from making everyday decisions to addressing complex global issues. One goal of instruction in this area is to get past assessment…

Effectively teaching scientific reasoning requires an understanding of the challenges students face when learning these skills. We designed an assessment that measures undergraduate student abilities to form hypotheses, design experiments, and interpret data from experiments in cellular and molecular biology. The assessment uses…
