This work is an attempt to see how physics undergraduates view the basic ideas of general relativity when they are exposed to the topic in a standard introductory course. Since the subject is conceptually and technically difficult, we adopted a "case studies" approach, focusing in depth on about six students who had just finished a one semester…

In recent years, the failure rate on first-year mathematics modules on Physics courses at Loughborough University has given cause for concern. It was feared that failure in the first year would result in students performing poorly in future mathematics modules. Hence, a proactive support system was introduced for the mathematically less…

This paper describes an action research approach toward an implementation of a new teaching methodology (specifically active learning) in a preparatory college chemistry classroom. The initial implementation involved the use of process-orientated guided inquiry (POGIL) activities. The treatment classes with either all POGIL activities during…

Three related courses examining the connection between chemistry and art have been developed for study-abroad programs in Florence, Italy, by faculty members at Gonzaga University and Mount Saint Mary's University. These courses are described with the intent of providing a general framework for the development of chemistry and art courses in other…

Metal oxalate synthesis and pyrolysis provides an opportunity for students to (i) learn stoichiometry, (ii) experience the consequences of proper stoichiometric calculations and experimental techniques, and (iii) be introduced to the relevance of chemistry by highlighting oxalates in context, for example, usages and health effects. At our…

Laboratory experiments that focus on protein folding provide excellent opportunities for undergraduate students to learn important topics in the expanding interdisciplinary field of biophysics. Here, we describe the use of Stern-Volmer plots to determine the extent of solvent accessibility of the single tryptophan residue (trp-59) in unfolded and…

In this laboratory experiment, students obtain information about the structure of a host-guest complex from the interpretation of circular dichroism measurements. The value and sign of the induced circular dichroism (ICD) on an achiral chromophore guest when it complexes with a cyclodextrin can be related to the guest penetration and its…

The laboratory synthesis of N,N-diethyl-3-methylbenzamide (DEET) is an effective way to combine organic chemistry teaching with a student's day-to-day life outside the classroom. Interest in DEET as a mosquito repellent has been heightened because of the rise of the West Nile virus across much of North America (1). To take advantage of the…

Liquid-vapor, solid-vapor, and solid-liquid-vapor equilibria are studied for the pure substance water, using modern equipment that includes specially fabricated glass cells. Samples are evaporatively frozen initially, during which they typically supercool to -5 to -10 [degrees]C before spontaneously freezing. Vacuum pumping lowers the temperature…

This case study places the high school student as a researcher for Carbonation Creators (fictional entity), a company responsible for making the Fizzy Forcer (a device to improve carbonation in previously opened bottles of soft drinks). The company faces a class-action lawsuit claiming that the Fizzy Forcer does not retain carbonation levels in…

Although worm bins have been used by K-12 and nonformal educators for decades, there is little evidence of their use in postsecondary education. The ease of use, maintenance, affordability, portability, and diversity of scientific concepts that can be demonstrated with a worm bin make it a valuable tool in college science classrooms. The purpose…

Wood is transparent for microwaves and due to its anisotropic structure has anisotropic dielectric properties. A laboratory experiment that allows for the qualitative demonstration and quantitative measurements of linear dichroism and birefringence in the microwave region is presented. As the proposed experiments are based on the anisotropy (of…

Interdisciplinarity is rapidly becoming a norm within both the professional and academic worlds, and the ability to collaborate is becoming an essential skill for all graduates. "Chemistry Is in the News" ("CIITN") is a curriculum that aims to teach students this skill by engaging student collaborative groups in a project that…

The requirement that universities prepare students in practical competences, and assess the extent to which pre-established objectives are achieved, is generally accepted to be of growing importance. As a result, on one hand, there is an increasing volume of research related to task performance in assessment. On the other hand, there are…

The propagation in time of a wavepacket is a conceptually rich problem suitable to be studied in any introductory quantum mechanics course. This subject is covered analytically in most of the standard textbooks. Computer simulations have become a widespread pedagogical tool, easily implemented in computer labs and in classroom demonstrations.…
