Highlights the importance of considering the hazards, precautions, and emergency procedures pertinent to the safe handling of chemicals before introducing students to the laboratory. Discusses safety hazards depending on the chemical's properties including flammability, corrosivity, toxicity, and reactivity; eye protection; and physical hazards.…

Positions writing centers in the painful paradoxes of literacy work and strips away the belief in innocence to make scholar-teachers more aware of the ways that literacy practices reproduce the social order and regulate access and subjectivity. Uses two stories about writing center students to illustrate the ways writing centers are inadvertently…

Describes an apparatus for crystal growth that was designed to study growth kinetics of small crystals from solutions and to obtain crystals of various substances. Describes the use of the apparatus in laboratory practical experiments in the field of crystal growth physics within the course "Solid State Physics". (JRH)

Presents an inquiry analysis tool and adaptation principles to help teachers evaluate and adapt laboratory instructional materials to be more inquiry-oriented. Based on the National Research Council's (NRC) essential features of inquiry. (NB)

Presents a laboratory experiment demonstrating the binding of calcium/calmodulin to calmodulin kinase II, which is important in the metabolic and physiological activities of the cell. Uses SDS polyacrylamide gel electrophoresis (PAGE). (YDS)

Describes the design and construction of a safe student quantitative conductivity apparatus. Discusses experimental results. (JRH)

Describes an apparatus that is stable and accurate enough for quantitative conductivity experiments but maintains the simplicity of construction and use as well as low cost. Discusses principles and implementation and the performance of the assembled apparatus. (JRH)

Reports on a survey that focuses on the content coverage of general chemistry courses for science and engineering majors, both in the classroom and in the laboratory, as reported by leading U.S. colleges and universities. Findings indicate relatively minor changes in content since a previous study conducted in 1986. Discusses shifts in content…

Modular laboratories provide technology education students with valuable experiences, but they are not the total solution. Technology education can aid problem solving, technological literacy, and school-wide curriculum integration, but not within the limits of the modular environment. (JOW)

Describes a lab activity in which yeast is used as a model system for human digestion. Uses Smith fermentation tubes to measure carbon dioxide released from fermentation. (Author/KHR)

If education is to meet the challenged posed by the U.S. productivity crisis and the large number of computer-assisted design (CAD) workstations forecast as necessary in the future, schools must integrate CAD into the drafting curriculum and become aggressive in providing CAD training. Teachers need to maintain close contact with local industries…

Argues that the meanings that writing center staff members assign to the words "tutor" and "tutee" run directly counter to the common meanings for the terms. Suggests replacing "tutor" with "writing assistant,""writing consultant," or "writing fellow." Suggests replacing "tutoring" with "discussion" or "consulting." Suggests replacing the term…

Argues that one productive approach to writing tutorials is to conceive them as performances and to encourage tutors to analyze them in this way. Analyzes tape-recorded narratives from tutors about conference experiences, which raise questions about the very nature of peer tutoring and help tutors clarify their roles. (SR)

Of 168 high school students, 107 were taught a horticulture unit that included a greenhouse laboratory experience, 61 received the unit without the lab. Lab experience resulted in significantly higher knowledge scores but made no significant difference in postexperiment attitudes. (SK)

Sketches a series of design decisions made at Utica College for a computer-supported writing facility, and their implications for the facility. Urges departments in similar situations to first of all establish instructional and operational goals to guide subsequent decisions, and suggests such goals. (SR)
