Efforts have been made to enhance teachers' understanding and teaching of NOS and/or SI by immersing teachers into the field and lab work of scientists through intensive summer institutes. Results have been mixed and the samples have been small. This may be due to several factors: implicit strategies to learn and teach about NOS and/or SI…

When she began teaching college geology and paleontology, the author anticipated some resistance from those who believed in a 6000 year-old earth, from creationists and those who advocate intelligent design, or possibly from students who simply wished to be consistent with the family religion and still take a course involving evolution and the Big…

This article reports a high school laboratory project whose theme is the motion of a small ball on cycloidal tracks. Models were built both of a brachistochrone and of a Huygens pendulum clock whose bob is constrained to move on a cycloidal path. Photogates and a data acquisition system were employed in order to investigate experimentally the…

A classroom exercise is described to introduce enzyme kinetics in an undergraduate biochemistry or chemistry course. The exercise is a simulation in which a student acts as an enzyme that "catalyzes" the unscrewing of a nut from a bolt. With other students assisting, the student enzyme carries out reactions with bolt-nut substrates under different…

For many decades, science educators have asked, "In what ways should learning the content of traditional subjects serve as the means to more general ends, such as understanding the nature of science or the processes of scientific inquiry?" Acceptance of these ends reduces the role of disciplinary context; the "Footprints Puzzle" and Oregon's…

When a federal court in 2005 rejected an attempt by the Dover, Pennsylvania, school board to introduce intelligent design as an alternative to evolution to explain the development of life on Earth, it sparked a renaissance in involvement among scientists in K-12 science instruction. Now, some of those teaching programs, studies, and research…

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…

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…

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…

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…

The authors of this paper portray the perspective of Professor Leon Cooper, a theoretical physicist, Nobel laureate, active researcher, and physics textbook author, on teaching science and on the nature of science (NOS). The views presented emerged from an interview prepared by the authors and responded to in writing by Professor Cooper. Based on…

It was refreshing to read Hisham Ghassib's (2010) article outlining his model of scientific knowledge production. Too few scholarly writings in creative studies and gifted education deal with issues at the large-scale, panoramic level of analysis. Ghassib (2010) would not disappoint Albert Einstein who lamented that "I have little patience with…

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.…

Many textbooks dealing with general relativity do not demonstrate the derivation of forces in enough detail. The analyses presented herein demonstrate straightforward methods for computing forces by way of general relativity. Covariant divergence of the stress-energy-momentum tensor is used to derive a general expression of the force experienced…

Students--and just about everyone else--tend to have a wide range of misconceptions about microbes. This article is aimed at changing how students view microbes by engaging them in two hands-on activities that are fun and creative and align with both the National Science Education Standards (NRC 1996) and the Essential Principles of Ocean Literacy…
