Compares students' perceptions of laboratory classes in chemistry and biology using the Science Laboratory Environment Inventory (SLEI). Results indicate significant differences on the subscales of "integration" and "open-endedness." Suggests that the SLEI can be considered as a sensitive tool to measure students' perceptions…

Discusses how experiments can offer students different points of view on the mathematical concepts presented in class and bring these concepts to life. Presents an experiment that demonstrates the interaction between mathematics and fluid dynamics. (Author/ASK)

Provides an overview--especially for administrators, developers, and tutors new to electronic tutoring environments--of issues and considerations unique to online tutoring that training programs need to address. Discusses three aspects of online tutoring: appreciating text-only environments, developing procedures for responding online, and…

Reports and analyzes the consequences of a university's abolishing any required writing course, using the case of the Director of Writing at Portland State University. Discusses effects on assessment, funding, service, and staff and staffing needs. (SR)

Describes a laboratory activity investigating important concepts in microbiology and ecology in which students design and carry out their own experiments and learn about microorganisms. Points out that all microorganisms are not dangerous and studies the relationship between Methylobacterium and plants. (YDS)

Presents an activity in which students perform a classic experiment designed by two Nobel Laureates to study mutation and scientific reasoning. (ASK)

Explores factors that can explain the rapid evolution of the water sciences. Discusses the investment in measuring systems that allow characterizations of water properties and the expansion of mathematical and systemic approaches to the interpretation of data. Contains 23 references. (DDR)

Describes a laboratory employed in undergraduate teaching that uses fruit flies to test student-selected compounds for their ability to cause mutations. Requires no prior experience with fruit flies, incorporates a student design component, and employs both rigorous controls and statistical analyses. (DDR)

A study examined the relationship between the creative thinking of 114 13 to 14-year-old females and scientific problem-solving ability. The students did well in the "preliminary trialing" stage and were more proficient in "interpreting" and "performing" process skills. The other three components, "communication,""planning," and "reflecting,"…

Presents findings of the images of science drawn upon in laboratory work by upper secondary and university students in academic streams with a science focus. Questions required students to comment on laboratory investigations carried out by research scientists or science students. Shows that students' reasoning has an epistemological and an…

Discusses collaboratories, defined as Internet-mediated science in which scientists are connected to each other, to instruments, and to data, independent of time and location. Explores past and current collaboratory efforts, including K-12 collaboratories, to identify factors that predict success and failure, and assesses directions for future…

Presents a demonstration that is a safe blend of two other vivid and memorable demonstrations. Combines two exothermic reactions involving granulated sugar to devise a reaction that produces a small amount of smoke and a growing column of black carbon. (DDR)

Discusses the biology of magnetobacteria and describes how they can be used in an empirical test of natural selection that takes three to four weeks. Contains 11 references. (WRM)

Describes the construction of a conductivity meter that includes a timer and a readout display that provides semiquantitative information. The meter can be made into a hand-held or lecture hall (demonstration) version. (WRM)

Presents guidelines for equipping physics labs with components from each of four technology-use categories: (1) computer interfacing; (2) modeling; (3) simulations; and (4) research-reference-presentation. Includes references to useful websites discussing educational technology. (WRM)
