It is no secret that secondary school writing centers offer many benefits to the schools and students they serve. However, one benefit that is unfortunately often overlooked is the opportunity for the writing center to serve as a connecting point for students, tutors, faculty, and staff to collaborate with writing centers at the college and…

The development, implementation, evolution, and evaluation of a research-based laboratory course which was created as an alternative to more traditional laboratory instruction is described. The course was able to engage the students in devising and executing their own experiments, the satisfaction of determining the outcomes of those experiments,…

In a culture or society with high collectivism, contingent orientation and constrained autonomy are the prominent characteristics of adolescents' self-construal. This article examined whether Taiwanese adolescents' contingency and autonomy were associated with their prevalent preferences for buffet consumption. Findings in a panel survey indicated…

The analytical system to teach the subtleties of assaying alpha-dicarbonyl compounds in wine is described. Spectrophotometry is determined to be minimally useful in the experiment where the GC-MS (methyglyoxal) method proved to be ideal to confirm that the compounds analyzed in the wine samples were indeed the glyoxals based on the formation of…

Scorpionate-type ligands and the original polypyrazolylborates are easy to synthesize, have good stability, and are quite user-friendly. Their thallium(I) salts are readily soluble in organic solvents that permits their use in organic media, or in two-phase aquo-organic solvent mixtures.

As blended language learning environments evolve within tertiary foreign language institutions, issues of power with regards to the privileging of electronic technologies come to the fore. Blended learning, or the principled mix of online and classroom-based activities, challenges the practices of traditional CALL and face-to-face teaching within…

Invited as a paper from E-Learn 2009 This study compared two programmes developed as a learning tool for students to practise basic laboratory procedures. One was a Flash simulation programme, the other a Second Life virtual reality programme. A cohort of 93 bioscience students participated in the between trial. A control group was used to…

This military-developed text contains the first section of a four-part course to train environmental support specialists. Covered in the individual course blocks are basic mathematics necessary to the study of waste processing and water analysis as well as waste and waste processing and water and water analysis (basic chemistry, air forced water…

A law passed by a state legislature requires that students in industrial arts shops and science laboratories must wear eye protective devices. Explanatory material presents the text of the bill and guidelines for implementation, including--(1) types of eye hazards, (2) types of protective devices, (3) administrating eye safety equipment, (4)…

As networking systems have become more complex and expensive, hands-on experiments based on networking simulation have become essential for teaching the key computer networking topics to students. The simulation approach is the most cost effective and highly useful because it provides a virtual environment for an assortment of desirable features…

A simple experiment to study thermionic emission, the Richardson-Dushman equation and the energy distribution function of thermionic electrons emitted from a hot cathode using a triode vacuum tube is described. It is pointed out that such a distribution function is directly proportional to the first derivative of the Edison anode current with…

Solid-liquid and liquid-liquid mixing experiments have been developed to provide students with a practical experience on suspension and emulsification processes. The laboratory focuses on the characterization of the process efficiency, specifically the influence of the main operating parameters and the effect of the impeller type. (Contains 2…

An undergraduate laboratory was designed for undergraduate students to make long persistent light emitting diode (LED) indicators using phosphors. Blue LEDs, which emit at 465 nm, were characterized and used as an excitation source. Long persistent phosphors, SrAl[subscript 2]O[subscript 4]:Eu[superscript 2+],Dy[superscript 3+] (green) and…

This paper proposes a different experimental setup compared with the traditional ones, in order to determine the acceleration of gravity, which is carried out by using a fluid at a constant rotation. A computerized rotational system--by using a data acquisition system with specific software, a power amplifier and a rotary motion sensor--is…

A course linking chemistry and archaeology was designed to introduce scientific principles and applications to students with little or no science background. The course could provide students an opportunity to explore the role of the sciences in archaeology and to discover the relationship between materials and the culture that produce them.
