An Integrated Approach to Introducing Biofuels, Flash Point, and Vapor Pressure Concepts into an Introductory College Chemistry Lab
Peer reviewed Peer reviewed
Direct linkDirect link
Hoffman, Adam R.; Britton, Stephanie L.; Cadwell, Katie D.; Walz, Kenneth A. – Journal of Chemical Education, 2011
Students explore the fundamental chemical concepts of vapor pressure and flash point in a real-world technical context, while gaining insight into the contemporary societal issue of biofuels. Lab activities were developed using a closed-cup instrument to measure the flash point of various biodiesel samples. Pre- and post-tests revealed that the…

Rowland-Goldsmith, Melissa – Biochemistry and Molecular Biology Education, 2009
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…

Hasrati, Mostafa; Hashemi, Reza – Quality in Higher Education, 2011
While research is abundant on quality assurance in higher education, very little has been done to study informal learning in general and its relation to quality assurance in particular. Reporting on a study of informal learning among PhD students in natural sciences in an Iranian university, this article is an attempt to address this issue.…

Stamatelos, G. M.; Stamatelos, A. M. – European Journal of Engineering Education, 2009
An academic legislative reform of the public university sector was recently initiated in Greece (since 2005). It was designed to respond to the requirements of convergence to a common frame of the European Space of Higher Education. This reform found significant resistance from university personnel and students, resulting in a very slow degree of…

Introducing Quality Control in the Chemistry Teaching Laboratory Using Control Charts
Peer reviewed Peer reviewed
Direct linkDirect link
Schazmann, Benjamin; Regan, Fiona; Ross, Mary; Diamond, Dermot; Paull, Brett – Journal of Chemical Education, 2009
Quality control (QC) measures are less prevalent in teaching laboratories than commercial settings possibly owing to a lack of commercial incentives or teaching resources. This article focuses on the use of QC assessment in the analytical techniques of high performance liquid chromatography (HPLC) and ultraviolet-visible spectroscopy (UV-vis) at…

Science Laboratories and Indoor Air Quality in Schools. Technical Bulletin.
Jacobs, Bruce W. – 1994
Some of the issues surrounding the indoor air quality (IAQ) problems presented by science labs are discussed. Described are possible contaminants in labs, such as chemicals and biological organisms, and ways to lessen accidents arising from these sources are suggested. Some of the factors contributing to comfort, such as temperature levels, are…
