Describes an activity designed for secondary school students that explains the global carbon cycle and the production of CO2 through soil respiration. (YDS)

Presents laboratory experiments to demonstrate the pH properties of different buffer solutions. (YDS)

Presents a tobacco haploid experiment in which students learn the cytogenetic technique of metaphase analysis of chromosomes and experience the basic principles of haploidy, diploidy, and polyploidy. (YDS)

Presents a mystery based on the well-known characters, Sherlock Holmes and Dr. Watson. Emphasizes qualitative inorganic analysis, laboratory observations, and oxidation-reduction processes. (Author/YDS)

Presents a science activity on consumer chemistry in which students explore artificial flavors that are commonly used in foods, such as isoamyl acetate and methyl salicylate. Includes instructor information and a student worksheet. (YDS)

Discusses work the authors did together addressing racial diversity in a writing center. Foregrounds their differences as well as their mutual vision, creating a bumpy ride for readers and interfering with modernist expectation of oherence, yet exposing the seams they think their readers need to see in order to understand how the fabrics of their…

Tests the hypothesis that, because it uses tri-dimensional sensory pathways which show a higher rate of neural activity than uni- or bi-dimensionals, lab-activity-based instruction is a more effective teaching strategy for learning science than verbal-based instruction. Applies manipulative teaching strategies that use visual, somatosensory, and…

Introduces a molecular biology course designed for environmental engineering majors using 16S ribosomal ribonucleic acid-targeted technology that allows students to identify and study microorganisms in bioreactor environments. (Contains 17 references.) (YDS)

Dicusses the effects of using laboratory assistants for disabled students' learning in the chemistry laboratory. Presents two case studies and general strategies for approaching laboratory experiences for disabled students. (KHR)

Discusses small-group apprenticeships (SGAs) as a method for introducing cell culture techniques to high school participants. Teaches cell culture practices and introduces advance imaging techniques to solve various biomedical engineering problems. Clarifies and illuminates the value of small-group laboratory apprenticeships. (Author/KHR)

Shares observations about the philosophy and services secondary level writing centers can provide. Suggests secondary writing centers provide miniclinics, study skills information, opportunities for instructors to work with the center staff, and effective writing to learn activities. Suggests that writing center personnel become involved in…

Suggests that the ideal relationship between the writing center and an English department's writing program is almost symbiotic, each benefiting the other and both forwarding writing as a powerful tool for writing. Describes the writing centers at Montana State University and University of Nevada, Reno. (RS)

Debate continues as to whether exercise training accelerates the growth of coronary collateral vessels. Animal research has produced positive results, but human studies have been disappointing, largely because of problems in experimental design and methodology. (IAH)

Discussion of software security in university computer laboratories focuses on the causes of computer viruses. Possible ways to detect an infected disk are described; strategies for professors, students, and computer personnel to eradicate the spread of a computer virus are proposed; and two resources for further information are given. (LRW)

Reviews the medical laboratory career ladder. Indicates that because of the shortage of health care workers, there is a need to reassess the other avenue of career development, namely experience. (JOW) (This file contains 41 resumes, CS739175 to CS739215.)
