Tracy, Charles; Cunningham, Elizabeth – Education in Science, 2014
This article reports on a plea directed to schools in England that changed status to an "academy" and thus lost their Local Authority Radiation Protection Adviser (RPA) service. These schools have been encouraged to do all that they can to hang on to their sources (radioactive equipment used in classroom experiments to investigate…

Gross, Deborah S.; Van Ryswyk, Hal – Journal of Chemical Education, 2014
Electrospray ionization mass spectrometry (ESI-MS) is a powerful tool for examining the charge of proteins in solution. The charge can be manipulated through choice of solvent and pH. Furthermore, solution-accessible, protonated lysine side chains can be specifically tagged with 18-crown-6 ether to form noncovalent adducts. Chemical derivatization…

Girault, Isabelle; d'Ham, Cédric – Journal of Science Education and Technology, 2014
When solving a scientific problem through experimentation, students may have the responsibility to design the experiment. When students work in a conventional condition, with paper and pencil, the designed procedures stay at a very general level. There is a need for additional scaffolds to help the students perform this complex task. We propose a…

De, Subhranil – Physics Education, 2014
The familiar system involving a uniform ladder sliding against a vertical wall and a horizontal floor is considered again. The floor is taken to be smooth and the wall to be possibly rough--a situation where no matter how large the static friction coefficient between the ladder and the wall, the ladder cannot lean at rest and must slide down.…

Widdicombe, A. T.; Ravindrarajah, P.; Sapelkin, A.; Phillips, A. E.; Dunstan, D.; Dove, M. T.; Brazhkin, V. V.; Trachenko, K. – Physics Education, 2014
The slow flow of a viscous liquid is a thought-provoking experiment that challenges students, academics and the public to think about some fundamental questions in modern science. In the Queensland demonstration--the world's longest-running experiment, which has earned the Ig Nobel prize--one drop of pitch takes about ten years to fall, leading to…

Ivanov, Dragia; Nikolov, Stefan; Petrova, Hristina – Physics Education, 2014
In this paper we present three different methods for testing Bernoulli's law that are different from the standard "tube with varying cross-section." They are all applicable to high-school level physics education, with varying levels of theoretical and experimental complexity, depending on students' skills, and may even be…

Castet, Frédéric; Méreau, Raphaël; Liotard, Daniel – Journal of Chemical Education, 2014
In this computational experiment, students use advanced quantum chemistry tools to simulate the photochromic reaction mechanism in naphthopyran derivatives. The first part aims to make students familiar with excited-state reaction mechanisms and addresses the photoisomerization of the benzopyran molecule by means of semiempirical quantum chemical…

Carroll, Christopher W.; Keller, Lani C. – Biochemistry and Molecular Biology Education, 2014
This adaptable graduate laboratory course on protein purification offers students the opportunity to explore a wide range of techniques while allowing the instructor the freedom to incorporate their own personal research interests. The course design involves two sequential purification schemes performed in a single semester. The first part…

Saxena, Sachin; Satsangee, Soami P. – Journal of Chemical Education, 2014
Remote access to real experiments is crucial for distance learners to experience the sciences. The exploitation of technology for this purpose is advantageous in global teaching and in exchange of ideas on a single front irrespective of distance barriers. Implementation of the distance method leads to cost-effective integrated-e-learning where…

Miller, W. R.; Lowman, M. D.; McCord, E., Jr.; Tripp, R. L.; Glenny, D. A.; Volpini, A. T. – European Journal of Educational Sciences, 2014
We conducted research to quantify tardigrade (water bear) density, diversity, and distribution in temperate forest canopies, and to promote opportunity for undergraduates with mobility limitations as field researchers. This ecology project was funded by the National Science Foundation (NSF) Research Experiences for Undergraduates (REU) program to…

Paul A. E. Piunno; Adrian Zetina; Norman Chu; Anthony J. Tavares; M. Omair Noor; Eleonora Petryayeva; Uvaraj Uddayasankar; Andrew Veglio – Journal of Chemical Education, 2014
An advanced analytical chemistry undergraduate laboratory module on microfluidics that spans 4 weeks (4 h per week) is presented. The laboratory module focuses on comprehensive experiential learning of microfluidic device fabrication and the core characteristics of microfluidic devices as they pertain to fluid flow and the manipulation of samples.…

Passante, Gina; Emigh, Paul J.; Shaffer, Peter S. – Physical Review Special Topics - Physics Education Research, 2015
Superposition gives rise to the probabilistic nature of quantum mechanics and is therefore one of the concepts at the heart of quantum mechanics. Although we have found that many students can successfully use the idea of superposition to calculate the probabilities of different measurement outcomes, they are often unable to identify the…

Rajala, Jonathan W.; Evans, Edward A.; Chase, George G. – Chemical Engineering Education, 2015
Third year chemical engineering undergraduate students at The University of Akron designed and fabricated a heat exchanger for a stirred tank as part of a Chemical Engineering Laboratory course. The heat exchanger portion of this course was three weeks of the fifteen week long semester. Students applied concepts of scale-up and dimensional…

Chacko, Priya; Appelbaum, Sarah; Kim, Heejoo; Zhao, Jinhui; Montclare, Jin Kim – Journal of Technology and Science Education, 2015
Students have access to the Internet at their fingertips via e-tablets and smart phones. However, the STEM fields are struggling to remain relevant in students' lives outside the classroom. In an effort to improve high school science curricula and to keep students engaged in the classroom, we developed a technology-rich bioengineering summer…
