The preparation of an ion-selective electrode for salicylate is described. The electrode incorporates an ion-pair of crystal violet and salicylate in a PVC matrix as the ion-selective membrane. Its use for the determination of acetylsalicylic acid in aspirin tablets is described. A similar experiment is described by Creager, S. E. Lawrence, K. D. Tibbets, C. R. in An Easily Constructed Salicylate-Ion-Selective Electrode for Use in the Instructional Laboratory, /. Chem. Educ. 1995, 72, 274-276. 

Significant problems have been identified in the science education literature about the laboratory/practical courses, in particular about the ineffectiveness of laboratory instruction in enhancing conceptual understanding (Hofstein, 2004 Hofstein Lunetta, 1982 2004). The type of laboratory instruction plays certainly an important role in this deficiency.

The revitalization of chemistry education has received much recent attention and taken many forms. Modes of teaching, textbooks, laboratory instruction— all aspects of the chemistry curriculum have undergone scrutiny for reform. A recent National Science Foundation report, Shaping the Future New Expectations for Undergraduate Education in Science, Mathematics, Engineering, and Technology characterizes the nature of the most successful curricular and pedagogical improvements ...

Last but not least, one of the most important, but sometimes a little bit neglected, aspects in the implementation of GLP concerns the instruction, education and training of personnel. This does not only involve technicians, laboratory workers, animal caretakers or field hands, but also - and this has to be especially emphasised - the prospective Study Directors. Only if all individuals in the test facility can be considered to be on an equivalent level of theoretical and practical knowledge with regard to the application of the GLP rules can the test facility be expected to work in a perfectly compliant way.

There has recently been considerable debate within the science and engineering communities about the effectiveness of laboratory instruction (Reid and Shah 2007, Adams 2009, Feisel and Rosa 2005). There is a general consensus that hands-on laboratory work is an essential component of undergraduate education in the sciences and engineering (Magin and Kanapathipillai 2000, Bhathal 2011) but more needs to be done to make laboratories more effective and better value for the costly equipment, dedicated technical staff, space and faculty time they require.

For some instruments, the manual may be needed with the instrument for proper operation. This is particularly true in educational laboratories. In such cases, the manufacturer vdll generally be happy to supply extra copies, or the significant parts of a manual may be copied on the office copy machine. In all cases, the original manual and instructions must be properly filed. 

First, by indulging his passionate belief in science for the people, he gave students the kind of hands-on education in chemistry that he had wanted as a young man. Before Frankland, students everywhere learned science from books most never even entered a laboratory. Working tirelessly over a period of 15 years, Frankland gradually changed that and dramatically improved the state of science education in Britain. He compiled a list of 109 experiments that students needed to understand firsthand in order to pass his examinations. He wrote a textbook that became a standard for chemistry instruction, in part because it incorporated his ideas on valency and organic structures and his newly developed notation system. 

Martin Heinrich Klaproth, a German chemist who was bom in Wemi-gerode in the Harz on December 1, 1743. When he was eight years old, the family became impoverished by a serious fire. Since there was little money left for the education of the three Klaproth boys, little Martin Heinrich earned his tuition by singing in the church choir. After receiving a little instruction in Latin at Wemigerode, he was apprenticed at the age of sixteen years to an apothecary. After five years of apprenticeship, he worked for four years in public laboratories at Quedlinburg... 

Much of the excitement over nanotechnology lies in the new science that is being discovered and the new tools that allow us to manipulate matter at the nanoscale, including individual atoms. A website has been established through a National Science Foundation-supported Materials Research Science and Engineering Center (MRSEC) at the University of Wisconsin-Madison to help move these ideas into educational and outreach venues (2). A video laboratory manual is available on the website that provides step-by-step instructions in the form of videoclips. 

An educational experiment cement rods with flax fibres The purpose of this educational experiment, which was developed in the materials science laboratory of my school, is to instruct and illustrate. Preferably simply experiments should be done to support theoretical knowledge. 

We are striving to develop a new laboratory curriculum that provides students with a short-term authentic research experience. Our research shows that achieving this goal requires excellent instructional materials, instructor understanding of the curriculum s goals, and thorough TA preparation. When these components are present, students receive an educational experience that they can really be involved in. The curriculum gives students the autonomy to decide how best to answer their research question, and their work is relevant in a much broader context than available in traditional chemistry laboratory curricula.
