Presents a laboratory experiment that examines the aggressive behavior of male paradise fish. Students design the experiment, collect data, and analyze and interpret the results. This activity is appropriate for biology, ecology, and animal behavior classes and allows students to be involved in the entire scientific process. (Author/NB)

This laboratory exercise affords students a hands-on experience learning about traditional dyes, fiber strength, and paper making. It is economical, simple to prepare, provides satisfactory results, and is student friendly. Dyes were extracted from plant leaves, stems, roots, and fruits. Hard-boiled eggs were place in the dyes for 15 minutes to…

This paper reports on a decade of research into the nature of interactions between writing center tutors and native speaker (NS) and non-native speaker (NNS) tutees. It explores and describes the structure of this interaction and the behaviors of NNS tutees, and of tutors when interacting with both NS and NNS tutees. It characterizes writing…

Professors have long assigned to their students works of which they were the author. The practice ranges from assigning commercially published textbooks they have written to having students buy a volume they have written and published or course packs made up of their own materials they have photocopied. Not only individual professors, but also…

The House of Science in Stockholm is a university science laboratory for physics, astronomy and biotechnology, entirely devoted to schools. The laboratory makes modern science accessible to teachers, school classes and individual students. It could serve as a model for universities and science centres that want to bridge the gap between school and…

Atmospheric optical effects can teach much about physics and especially optics. Coronae--coloured rings around the sun or moon--are large-scale consequences of diffraction, which is often thought of as only a small effect confined to the laboratory. We describe coronae, how they are formed and experiments that can be conducted on ones in the sky.…

"Cell Biology Education" calls attention each quarter to several Web sites of educational interest to the biology community. The Internet provides access to an enormous array of potential teaching materials. In this article, the authors describe one approach for using the World Wide Web to develop a new college biology laboratory exercise. As a…

Cinemicrography--the capture of moving cellular sequences through the microscope--has been influential in revealing the dynamic nature of cellular behavior. One of the more dramatic cellular events is mitosis, the division of sister chromatids into two daughter cells. Mitosis has been extensively studied in a variety of organisms, both…

This paper describes an educational package for use in tertiary level tissue engineering education. Current learning science principles and theory were employed in the design process of these educational tools. Each module started with a challenge statement designed to motivate students and consisted of laboratory exercises centered on the "How…

This article presents results of the first two years of the introduction of a critical thinking (CT) component to standard freshman astronomy lab exercises for nonmajors. The component consists of a series of probing questions folded into the exercises, plus a formal grading rubric. The grading rubric is adapted from the generalized Washington…

Understanding natural and human-induced hazards is an important part of the standards-based science curriculum. Experience, however, indicates that the topic is a difficult one for many students. We have developed an exciting investigative laboratory exercise that uses simulated food-based case studies to promote critical thinking and improve…

Lyle V. Jones served as director of the Thurstone Psychometric Laboratory and also became the Vice Chancellor and Dean of the Graduate School of the University of North Carolina (UNC). Jones has been a Research Professor at UNC since 1992. This article presents an interview with Jones wherein he talked about his career as a researcher. Jones also…

An experiment is proposed for learning the principles of radio. A simple radio receiver illustrates amplitude modulation and demodulation, the selectivity of a receiver and the features of a directional antenna. Both normal and computerized versions of the experiment are described. The computerized experiment employs the "ScienceWorkshop"…

The transition to kindergarten can be difficult for both parents and children. Teachers, administrators and community providers can help ease this process by developing effective transition programs and materials for families in anticipation of the school year. However, such resources are often time-consuming and costly. To offer a solution, a…

The stereoselective synthesis of an aryl vinyl bromide is accomplished in a rapid microscale reaction of "trans"-4-methoxycinnamic acid with N-bromosuccinimide in dichloromethane. The product is purified by dry column vacuum chromatography and its stereochemistry is determined by [superscript 1]H NMR. TLC, GC and GC-MSD can also be used. This…
