This study explored the relationships between English language proficiency and performance in online, asynchronous science courses. Each participant completed a Language Background Questionnaire (LBQ) to indicate if English was not their native language, thus categorizing them as an English Language Learner (ELL). The Combined English Language…

Project-based learning (PBL) has been found to deepen learning and develop employability skills for students through active engagement with the learning materials. Foundation, first and second year Biomedical Science students at the University of Sussex were introduced to a PBL exercise. Each class had an approximate student to staff ratio of…

Large enrollments in undergraduate courses pose several teaching and learning challenges that impact students' learning experience and performance. Implementing co-learning activities in tutorials of large courses can help mitigate these challenges and improve the learning environment. One type of collaborative learning activity that has become…

In the field of education, ChatGPT has become a topic of debate for its usefulness as a learning tool. This article focuses on non-science majors' (n = 29) perceptions of a ChatGPT enabled final exam, where, prior to the exam, students wrote papers on science and sustainability and, during the final exam, students were asked to compare their paper…

Upper-division undergraduate students are introduced to polymer processing using material extrusion fused filament fabrication 3D printing to make poly(lactic acid) (PLA) mechanical testing specimens. Computer aided design and slicing software packages are used to demonstrate the process of preparing 3D computer models for printing. Following the…

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…
