The Laboratory for Research on the Structure of Matter (LRSM), University of Pennsylvania, was built in 1965 as part of the Advanced Research Projects Agency's (ARPA) Interdisciplinary Laboratories (IDL) program intended to foster interdisciplinary research and training in materials science. The process that led to the construction of the…

Purpose: This paper aims to explore consumer attitude towards service failure and recovery in the higher education in general and with respect to teaching, examination, library, computer lab, administration and infrastructure in particular. Design/Methodology/Approach: The data are collected from 120 students of three undergraduate colleges of…

This report is the second from the congressionally-mandated evaluation of the Regional Educational Laboratory (REL) program authorized by the Education Sciences Reform Act (P.L. 107-279). For this report, 8 (out of 24) impact study reports produced by the RELs under their 2006-2011 contracts and published by IES were rated by expert panels for…

It is shown that the well-known linear variation of p-n diode terminal voltage with temperature at different fixed forward currents allows easy and accurate determination of the semiconductor ideality factor and bandgap from only two data points. This is possible if the temperature difference required to maintain the same diode voltage drop can be…

Remote access laboratories (RALs) were first developed in 1994 in Australia and Switzerland. The main purposes of developing them are to enable students to do their experiments at their own pace, time and locations and to enable students and teaching staff to get access to facilities beyond their institutions. Currently, most of the experiments…

This laboratory experiment exposes students to the chemistry of self-healing polymers based on a Diels-Alder reaction. Students accomplish a multistep synthesis of a monomer building block and then polymerize it to form a cross-linked polymer. The healing capability of the polymer is verified by differential scanning calorimetry (DSC) experiments.…

As part of an NSF-funded Course Curriculum and Laboratory Improvement (CCLI) project that seeks, in part, to increase student exposure to scientific instrumentation, a gas chromatography experiment has been integrated into the second-semester general chemistry laboratory curriculum. The experiment uses affordable, commercially available equipment…

Used since the time of the ancient Egyptians as a method for transferring liquids from one vessel to another, the siphon is a dependable tool. Although, the act of siphoning beer from a fermentation barrel or wine from a demijohn is a skill that has been passed down from generation to generation, do we really know how the siphon works? It is…

In 1984, a teacher was successfully prosecuted by the Health and Safety Executive. The case centred around chemically prepared hydrogen that was dried by bubbling it through concentrated sulfuric(VI) acid and then passed over hot copper(II) oxide. The procedure was often carried out quantitatively to find the mass of copper in a sample of…

The formulation of a scientific prediction by students in college-level laboratories is proposed. This activity will develop the students' ability to apply abstract concepts via deductive reasoning. For instances in which a hypothesis will be tested by an experiment, students should develop a prediction that states what sort of experimental…

Thirty-six pre-university chemistry students and two chemistry teachers used flow chemistry as a technology for the synthesis of methyl orange. FutureChemistry and VU University Amsterdam cooperatively created FlowStart Remote, a device that enabled the students to remotely conduct this synthesis and in real time monitor and control the device via…

A blended approach encompassing problem-based learning (PBL) and structured inquiry was used in this laboratory exercise based on the congenital disease Osteogenesis imperfecta (OI), to introduce commonly used techniques in biomolecular analysis within a clinical context. During a series of PBL sessions students were presented with several…

General scientific literacy includes understanding the grounds on which scientific claims are based. The measurements scientists make and the data that they produce from them generally constitute these grounds. However, the nature of data generation has received relatively little attention from those interested in teaching science through inquiry.…

The Na[superscript +]-glucose cotransporter is a key transport protein that is responsible for absorbing Na[superscript +] and glucose from the luminal contents of the small intestine and reabsorption by the proximal straight tubule of the nephron. Robert K. Crane originally described the cellular model of absorption of Na[superscript +] and…

This paper describes the authors' experiences transforming a "cookbook" lab into an inquiry-based investigation and the powerful effect the inquiry-oriented lab had on our students' understanding of lenses. We found the inquiry-oriented approach led to richer interactions between students as well as a deeper conceptual…
