A novel approach is described using primary literature manuscripts for the final examination of an upper level undergraduate course in virology. This innovative technique was applied as an alternative to a core comprehensive final examination. A recent primary literature paper in virology was assigned several weeks before the end of the semester.…

We describe a series of three experiments in which students develop a model system for measuring the LC50 of household substances, using grass seed as the model organism. Students use statistical methods to compare two samples (using chi-square and Student's "t"-tests), conduct a two-level multifactor experiment to look at multiple…

A relatively large number of organic and inorganic chemistry reagents are air- or moisture-sensitive, and undergraduate students should be trained in their use. When handling such reagents, it is important to select the correct syringe and to use that syringe correctly. We have found that the best syringe for use in an undergraduate setting is a…

The concept of black body is of primary importance in studying the energy transfer of thermal electromagnetic radiation at all wavelengths. Several physical bodies like incandescent lamps, electric heaters, stoves, the sun and the other stars, microwave background radiation, etc., are considered to be black bodies as their radiation spectra fits…

RAMP is an acronym for the process "recognize hazards, assess risk, minimize risk, and prepare for emergencies". This paper describes these four steps in the context of undergraduate instruction about chemical health and safety.

World-class science requires inspiration, so how can we spark creativity in the modern university environment? Creativity does not come automatically: in the modern age, factors from electronic devices to time pressure can stifle creative thought. Yet, to solve the major problems of the future, it will be essential to stimulate creativity in…

In undergraduate chemistry curricula that include computational modeling, students may gain first-hand experience in both introductory and advanced applications of this technique. However, although students can be exposed to the predictive power of computational work, its capabilities are often limited to determining the intrinsic properties of…

All students deserve access to effective, equitable physics education. Postsecondary faculty have been shown to be unprepared to support students with disabilities in their classes, and popular, research-based introductory physics curricula do not adequately plan for variations in learners' needs, abilities, and interests. It is urgent to address…

This research draws on Legitimation Code Theory (LCT) to understand the epistemic dimension of the higher education classroom discourse of a professor who is well evaluated by his students. In expository science classroom discourse, concepts are loaded with different meanings, a process that is called "condensation of meanings" in LCT,…

Students often struggle to make interdisciplinary connections and cite a lack of opportunity to make such connections. To address this issue, we are developing activities aligned with the framework of three-dimensional learning that provide students with opportunities to make connections between chemistry concepts and biological phenomena. Here,…

In this paper, the main purpose is to describe the development and use of three flowcharts for identifying types of isomers and naming coordination compounds. The first flowchart is designed to help students identify the type of isomers between the two coordination compounds. The second one is is designed to identify the type of stereoisomerism.…

This paper deals with the advantages and disadvantages to both the faculty member and to the students of using the answer-until-correct multiple-choice test format for a class specifically designed for non-STEM majors, who need a breath of knowledge science course. Comments from students are given about why they prefer answer-until-correct…

High-performance liquid chromatography is one of the primary techniques covered in the undergraduate analytical chemistry curriculum. This technology report describes the use of a portable capillary-scale instrument that can provide similar performance to a benchtop instrument but generates less solvent waste and enables operation in nonlaboratory…

In answer to calls for research about professional change, this study addressed the question: What is involved in college science faculty readiness for change in instructional practice? The setting was a professional development experience in oceanography/marine science and paleoclimatology among 32 faculty from 2- and 4-year colleges. Ten of the…

Oxygen reduction reaction (ORR),as a multielectron electrode reaction, is an important electrochemical reaction in the field of electrochemical energy storage systems. Herein, a new advanced electrochemical laboratory experiment is designed for undergraduates to master the preparation of oxygen reduction catalytic electrode. Students can use…
