Most, if not all, industrial technology (IT) programs have laboratories or workshops. Often equipped with modern equipment, tools, materials, and measurement and test instruments, these facilities constitute a major investment for IT programs. Improper use or over use of program facilities may result in dirty lab equipment, lost or damaged tools,…

Increasing emphasis on leadership in medical education has created a need for developing accurate evaluations of team leaders. Our study aimed to compare the accuracy of self- and peer evaluation of student leaders in the first-year Human Structure block (integrated gross anatomy, embryology, and radiology). Forty-nine first-year medical students…

THE MANY POSSIBLE VARIATIONS OF LANGUAGE LABORATORY SYSTEMS WERE DESCRIBED, AND RELATIVE ADVANTAGES AND LIMITATIONS OF EACH WERE DISCUSSED. DETAILED GUIDANCE ON PURCHASING LANGUAGE LABORATORY EQUIPMENT WAS PROVIDED THROUGH (1) DEFINITION OF HIGH-QUALITY SPEECH REPRODUCTION, (2) DISCUSSION OF TECHNICAL FACTORS WHICH AFFECT ITS ACHIEVEMENT, AND (3)…

The use of green metrics to compare three bromination laboratory procedures demonstrates the effectiveness of an incremental greening process for chemistry curricula. Due to this process, the bromination of alkenes can be introduced to students through the use of a safe, effective, modern practice.

The three-step synthesis of Geodken's macrocycle, H[subscript 2]C[subscript 22]H[subscript 22]N[subscript 4], (5,14-dihydro-6,8,15,17-tetramethyldibenzo[b,i]-[1,4,8,11] tetraazacyclotetradecahexane), in an overall yield of 65% is described. By utilizing the synthesis of the macrocycle's dichloride salt, H[subscript 2]C[subscript 22]H[subscript…

The reactivity and orientation effects of a substituent are analyzed by using HPLC to determine the competitive nitration of the benzene-toluene and benzene-fluorobenzene mixtures. The results have shown that HPLC is an excellent instrumental method to use in analyzing these mixtures.

Teacher professional development is one of the most powerful influences on student achievement, and professional learning communities can be an excellent vehicle for high-quality PD. Mindich and Lieberman examine ways to implement effective PLCs. Education research has found that collegial work is connected to teachers' professional growth and…

Given the emphasis on community engagement in higher education, academic departments need to become more involved in the community. This paper discusses a number of outreach activities undertaken by the chemistry department at Rhodes University, South Africa. The activities range from service learning to community engagement with teachers and…

From October 2003 to April 2008 a systemic reform of the Mechanical Engineering program at The City College of New York was undertaken with the goal of incorporating emerging technologies (such as nanotechnology, biotechnology, Micro-Electro-Mechanical Systems (MEMS), intelligent systems) and new teaching methodologies (such as project based…

A comprehensive survey on the Internet based virtualisation of experiments is presented, covering several individual as well as collaborative efforts in various engineering disciplines. From this survey it could be concluded that there is a pressing need to develop full-fledged remote laboratory experiments for integrated directly into engineering…

Describes an experimental procedure that can be used to determine the potential bacterial contamination of stagnant water in emergency laboratory eyewash bottles. Contains 11 references. (WRM)

Micropipetting is an important skill that plays a very active and critical role in the molecular biology laboratory. It is imperative for a person handling micropipettor to know the correct way of using it so that accurate and precise results are achieved.

Studies of protein function increasingly use multifaceted approaches that span disciplines including recombinant DNA technology, cell biology, and analytical biochemistry. These studies rely on sophisticated equipment and methodologies including confocal fluorescence microscopy, mass spectrometry, and X-ray crystallography that are beyond the…

In this article, we present an overview of a suite of light and spectroscopy education materials developed as part of Project LITE (Light Inquiry Through Experiments). We also present an analysis of how introductory college astronomy students using these Project LITE materials performed on the Light and Spectroscopy Concept Inventory (LSCI)…

Conventional physics laboratory courses generally include an emphasis on increasing students' ability to carry out data analysis according to scientific practice, in particular, those aspects that relate to measurement uncertainty. This study evaluates the efficacy of the conventional approach by analyzing the understanding of measurement of…
