A new lecture/laboratory course to offer advanced biochemical training for undergraduate and early graduate students has been developed in the Department of Chemistry at the University of Nebraska at Omaha. This unique course offers students an opportunity to work hands-on with modern instrumentation not normally found in a predominately…

Science instruction literature provides us with goals for laboratory instruction and guidelines for designing and implementing science labs in the post-secondary setting. How well are we doing in our attempt to provide a meaningful and positive learning experience for our students? This paper describes the results of a study to determine whether…

For the past several years, a team in the Department of Electrical Engineering (EE), National Chung Cheng University, Taiwan, has been establishing a pedagogical approach to embody embedded systems in the context of robotics. To alleviate the burden on students in the robotics curriculum in their junior and senior years, a training platform on…

Purpose: This paper aims to report on a pilot research project designed to explore if new mobile augmented reality (AR) technologies have the potential to enhance the learning of clinical skills in the lab. Design/methodology/approach: An exploratory action-research-based pilot study was undertaken to explore an initial proof-of-concept design in…

Pre-laboratory work has been shown to be an effective investment at undergraduate level in chemistry at the University of Bristol. A Dynamic Laboratory Manual (DLM) has been developed to allow undergraduate students to rehearse practicals using virtual experiments, video clips and a range of assessment support. The DLM has been shown to be highly…

DNA microarray is an ordered grid containing known sequences of DNA, which represent many of the genes in a particular organism. Each DNA sequence is unique to a specific gene. This technology enables the researcher to screen many genes from cells or tissue grown in different conditions. We developed an undergraduate lecture and laboratory…

We present a new, low-cost method of building an all copper heat-pipe oven that increases the practicality of this device in advanced undergraduate instructional labs. The construction parts are available at local hardware and plumbing supply stores, and the assembly techniques employed are simple and require no machining. (Contains 1 footnote, 3…

Euler's formula for the buckling of an elastic column is widely used in engineering design. However, only a handful of engineers will be familiar with Euler's classic paper "De Curvis Elasticis" in which the formula is derived. In addition to the Euler Buckling Formula, "De Curvis Elasticis" classifies all the bent configurations of elastic rod--a…

The power distributions of nearly all major countries have accepted three-phase distribution as a standard. With increasing power requirements of instrumentation today even a small physics laboratory requires a three-phase supply. While physics students are given an introduction to this in passing, no experimental work is done with three-phase…

Bacteria are ubiquitous in our world. From our homes, to our work environment, to our own bodies, bacteria are the omnipresent although often unobserved companions to human life. Physicists are typically untroubled professionally by the presence of these bacteria, as their study usually falls safely outside the realm of our typical domain. In the…

Phosphorylation of proteins by protein kinases is an important mechanism in the regulation of protein activity. Among hundreds of protein kinases present in human cells, PKA, the first kinase discovered, belongs to the most important and best characterized group of these enzymes. The author presents an experiment that analyzes the "in vitro"…

The synthesis and analysis of a copper hydroxy nitrate provides an exposure to a simple ionic synthesis, qualitative analysis of copper and nitrate, two gravimetric analyses (copper and nitrate), one volumetric analysis (hydroxide), and a colorimetric analysis (copper). The results allow the student to determine the identity of the double salt and…

Activity-based collisional analysis is developed for introductory physics and astronomy laboratory experiments. Crushable floral foam is used to investigate the physics of projectiles undergoing completely inelastic collisions with a low-density solid forming impact craters. Simple drop experiments enable determination of the average acceleration,…

Technology was integrated into service-learning activities to create an interactive teaching method for undergraduate students at a large research institution. Chemistry students at the University of Central Florida partnered with high school students at Crooms Academy of Information Technology in interactive service learning projects. The…

Live organisms versus digital video of the organisms were used to challenge students' naive ideas and misconceptions about blood, the heart, and circulatory patterns. Three faculty members taught 259 grade 10 biology students in a California high school with students from diverse ethnolinguistic groups who were divided into 5 classes using…
