The feasibility of using current software, such as PC-Duo, PCAnywhere or LabVIEW, in training students in instrumental analysis from a remote location is investigated. Findings show that creation of online features is crucial to the use and learning by students and the development of a suitable Web site, which provides an easy-to-use interface to…

The Model Science Lab, a constructivist approach to teaching, strengthens urban science teachers' teaching practice. The retention rate of Houston science teachers who took part in the program was found to be very high and the cost of the Model Science Lab has proven less expensive per student than most other professional development options.

An experimental exercise on analytical proficiency studies in collaborative trials is proposed. This practical provides students in advanced undergraduate courses in chemistry, pharmacy, and biochemistry, with the opportunity to improve their quality assurance skills. It involves an environmental analysis, determining the concentration of a…

A laboratory exercise used in the senior biochemistry course at the University of Winnipeg for three years is discussed. It combines liquid chromatography and absorbance spectroscopy and also allows the students to produce a quantitative result within a single three-hour period.

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.

Green chemistry is the utilization of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Some of the philosophical questions and practical decisions that have guided the greening of the organic chemistry laboratory at Hendrix College in…

The potassium salt is an easy product to synthesize in an introductory course on inorganic chemistry and the students are required to prepare this product in order to improve their laboratory skills and as an introduction to the synthesis of coordination compounds. The complex potassium tris (oxalato) ferrate (III) is used to illustrate the…

A novel method to investigate the pollen diets of hoverflies is described. The method dispenses with the need for dissection skills or the use of hazardous chemicals thus making it particularly useful for school, college or undergraduate projects and for amateurs. It utilises the properties of the indigestible pollen coat, or exine, which enables…

One easy way to reduce the number of accidents in the lab is to go "green." Green chemistry, or sustainable chemistry, emerged about a decade ago, but the concept has been practiced for centuries by indigenous people of many continents. The basic principles of green chemistry are that you should use only what you need and recycle what you can.…

In 1993 two of the authors of this article published a survey of introductory biology laboratory instruction in colleges and universities of the U.S. in order to document the status of laboratory instruction, and in particular, the use of inquiry based instruction. In this article, the authors present a survey that examined the changes that may…

Most biology students have the opportunity to look at protozoa under the microscopes or keep mealworms in a bowl. They may manipulate the heart rate of "Daphnia" or calculate the respiration of plants. They may even grow corn in the spring or keep fish and a small rodent or two. But once the class hamster grows testy from being awakened every…

The author discusses mentoring and training strategies that enhance adjunct faculty members' teaching effectiveness in undergraduate science laboratories and foster a sense of common enterprise within the institutional environment. These strategies include the preparation of an "Adjunct Faculty Handbook", mentoring and peer-support programs, and…

First-year physics students at the Technical University of Budapest carry out a wide range of measurements in the Basic Level Physics Teaching Laboratory. One of the most exciting experiments is the investigation of a chaotic double pendulum by a V-scope, a powerful three-dimensional motion tracking system. After a brief introduction to the…

Computer-based tools that enable students to collect, display and analyse data in real time have catalysed the design of a laboratory curriculum that allows students to master a coherent body of physics concepts while acquiring traditional laboratory skills. This paper describes "RealTime Physics", a sequenced introductory laboratory curriculum…

This paper describes a project undertaken as an interdisciplinary effort among four science departments, two disabilities services offices, and special education personnel to investigate the use and success of assistive technology devices as well as other equipment modifications in an attempt to transform science laboratories into environments…
