Curricular changes continue at United States medical schools and directors of gross anatomy, microscopic anatomy, neuroscience/neuroanatomy, and embryology courses continue to adjust and modify their offerings. Developing and supplying data related to current trends in anatomical sciences education is important if informed decisions are going to…

Purpose: New teaching concepts in IS are highly relevant to deliver practical skills to IS students, as demanded by business practice. There are different approaches for providing knowledge. The authors differentiate between teacher-centered and learner-centered approaches when designing new IS courses. The latter is characterized by creating…

Many aquatic organisms survive by filter feeding from the surrounding water and capturing food particles. We developed a laboratory exercise that allows students to measure the effects of filtering by fresh water mussels on water turbidity. Mussels were acquired from Wards Scientific and exposed to a solution of baker's yeast. Over a period of one…

This experiment enlightens students on the use of environmental indicators and inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and demonstrates the ability of these monitoring tools to measure metal deposition in environmental samples (both as a result of lab-simulated and real events). In this two-part study, the initial…

In this paper we suggest a simple technique for validating the Goldstein-Wehner law for a stratified positive column of dc glow discharge while studying the properties of gas discharges in an undergraduate laboratory. To accomplish this a simple device with a pre-vacuum mechanical pump, dc source and gas pressure gauge is required. Experiments may…

Introduced to study components of ionized gas, the mass spectrometer has evolved into a highly accurate device now used in many undergraduate and research laboratories. Unfortunately, despite their importance in the formation of future scientists, mass spectrometers remain beyond the financial reach of many high schools and colleges. As a result,…

Many studies that evaluate the introduction of technology in the classroom focus on student performance and student evaluations. This study focuses on instructor evaluation of the introduction of virtual microscopy into an undergraduate anatomy class. Semi-structured interviews were conducted with graduate teaching assistants (TA) and analyzed…

Liquid-free cryogenic devices are acquiring importance in basic science and engineering. But they can also lead to improvements in teaching low temperature and solid-state physics to graduate students and specialists. Most of the devices are relatively expensive, but small-sized equipment is slowly becoming available. Here, we have designed…

Biological systems and living processes involve a complex interplay of biochemicals and macromolecular structures that can be challenging for undergraduate students to comprehend and, thus, misconceptions abound. Protein synthesis, or translation, is an example of a biological process for which students often hold many misconceptions. This article…

An undergraduate biochemistry laboratory experiment is described that will teach students the practical and theoretical considerations for measuring the equilibrium dissociation constant (K[subscript D]) for a protein/DNA interaction using electrophoretic mobility shift assays (EMSAs). An EMSA monitors the migration of DNA through a native gel;…

Objective: The authors evaluated the time course of the treatment effect of Osmotic-Release Oral System methylphenidate (OROS[R] MPH) HCl (Concerta[R], Raritan, NJ) CII in children with ADHD. Method: Data were combined from two double-blind, randomized, placebo-controlled, cross-over, analog classroom studies in children (9-12 years) with ADHD.…

While most scientists agree that laboratory work is an important part of introductory science courses, there is scant evidence for the relationship between laboratory work and student learning, particularly at the college level. This work reports the quantitative component of a mixed-methods study of the effect of cooperative problem-based…

Many quantum mechanical models are discussed as part of the undergraduate physical chemistry course to help students understand the connection between eigenvalue expressions and spectroscopy. Typical examples covered include the particle in a box, the harmonic oscillator, the rigid rotor, and the hydrogen atom. This article demonstrates that…

An approximate formula for the period of pendulum motion beyond the small amplitude regime is obtained based on physical arguments. Two different schemes of different accuracy are developed: in the first less accurate scheme, emphasis is given on the non-quadratic form of the potential in connection to isochronism, and a specific form of a generic…

The University of British Columbia (UBC) recently celebrated the opening of its Centre for Interactive Research on Sustainability (CIRS), a living laboratory for researchers to teach, test, and study the long-term impact of sustainable practices and technologies. Featuring advanced building controls, sensing technology, and management software…
