Describes an experiment in which the density of solutions of known sugar concentrations is measured. Data are then used to determine sugar content in commercial beverages. (DDR)

Suggests that writing centers should become campus leaders in the development and use of computers for writing, and should form reciprocal partnerships that require trust, commitment, and open communication. Argues that through successful collaborative projects like computer writing classrooms and online writing labs, writing centers help to shape…

Offers an overview and schema for understanding frequently used network technologies available for Online Writing Labs (OWLs)--electronic mail, gopher, World Wide Web, newsgroups, synchronous chat systems, and automated file retrieval systems. Considers ways writing centers' choices among these technologies are impacted by user access, network…

Illustrates how a three-person collaboration facilitated introduction of computer technology into a writing center. Discusses how an ongoing and constantly developing understanding between the writing center director, an instructional designer, and the technical coordinator allowed the introduction of computers to be an intentional process.…

Suggests that weekly participation in an e-mail discussion group by students in a tutor-training class led to productive dialogue concerning intersections between composition theory/research and writing center pedagogy. Argues for the value of asynchronous conferencing as a writing-to-learn methodology particularly relevant to the collaborative…

Describes the use of mobile labs for training at remote sites. Highlights one, at the St. Louis (Missouri) County Library, that trains librarians on the use of the integrated library system; the other, at the South Central Regional Library Council in Ithaca, New York, provides training in computer applications to consortium members. (LRW)

Points out that the standard bell-jar model used to illustrate breathing has some features that may lead to a misunderstanding of the mechanism of ventilation. Proposes modifications to the model. (DDR)

Examines the nature of the relationships tutors create with their clients in a writing center. Finds that asking open-ended questions, echoing each other's speech, and using qualifiers are ways tutors worked toward collaboration; and that, in a number of cases, an undue or misdirected emphasis on the collaborative approach resulted in wasting time…

Draws data from student responses to the Science Laboratory Environment Inventory (SLEI) and a curriculum analysis of the implemented laboratory tasks. Involves biology, chemistry, and physics students (N=387) in 20 classes in Tasmania, Australia. Contains 23 references. (DDR)

Presents an open-ended experiment designed to observe a range of processes and effects associated with electrolysis of an aqueous solution of copper sulfate. Lists materials and procedures. (DDR)

Reports on how science teachers might work to improve their students' use of science process skills in ways that will contribute to their meaningful learning during laboratory activities. (Author/WRM)

Studied use of the Internet by college students by determining sites selected on 6 of 70 computers in a college computer laboratory. The overwhelming use of the Internet in this open lab conformed to university acceptable-use policy, with almost no use of the computers to contact pornographic sites. (SLD)

Claims writing centers of the future will be more reliant on technology, need more second-language acquisition specialists, expand beyond the physical boundaries of a single center, and assume a more prominent role in research. (NH)

Presents a homemade, safe, effective, and inexpensive reactor vessel for ultrasonic horns with applications in microscale experiments in teaching and research laboratories. The reactor vessel is designed for an ultrasonic probe that allows reactions to be run at the microscale level at a wide range of temperatures and under inert atmosphere.…

Describes equipment used for a magnetic force experiment that is capable of producing precise results but rugged enough to withstand handling by several hundred undergraduate students per year. (WRM)
