Ecological, interdisciplinary, and interconnected laboratory lessons focusing on magneticism: (1) producing electric power; (2) magnetics and magneticism; (3) electomagnetism (2 parts); and turbines (2 parts). Lessons, designed as precursor for students to make choices in electricity production, use a directed inquiry approach. (MCO)

Discusses the functioning of campus children's centers in the college community. Communities that are an integral part of of the center's functioning are identified as sponsors, producers, and consumers. The conditions under which they establish relationships are common geographic location, values and interests, history, and tasks. (SH)

Two motifs of the Prehensive Leadership Model (PLM) are applied to efforts to solve problems related to stepchild status and low morale that are typical of campus child care centers. The importance of the PLM distinction between general and special leadership is discussed. (SH)

Describes two classroom experiments that investigated the effects of using projected-display computers: the first compared teaching a course using a projected display with teaching the course in a computer lab; and the second compared using a computer and projected display with standard lectures. Effects on test scores are discussed. (three…

Provides an update and expansion of an earlier "Delphi Study" which predicted changes that might occur resulting from the impact of technology on the teaching of writing. Provides comments based on recent research. Discusses two books that focus specifically on technology and writing. (MG)

Describes use in Appalachia of "Writing to Read," IBM-developed computer-assisted phonetic literacy program for first graders. Describes program's premise, history, and technology. Program uses phonetics, emphasizing student expression over spelling and punctuation. Describes establishment and use of literacy laboratories in West…

Contends that, by teaching economics as a laboratory science, using computers, students can be helped to think like economists. Describes computer laboratory exercises and a new economics curriculum being implemented at Denison University (Ohio). (DB)

This article describes a program providing a school district's most able high school students with advanced laboratory experience through access to facilities in an area university. Subjects studied include electronics, nutrition, and microbiology. Professors working with the students are interviewed and other experts comment on this approach. (PB)

The use of an olfactory acid-base indicator in titrations for visually impaired students is discussed. Potential olfactory indicators include eugenol, thymol, vanillin, and thiophenol. Titrations performed with each indicator with eugenol proved to be successful. (KR)

Describes relatively simple and inexpensive experiments for demonstrating the immune response to honeybee venom in the American cockroach, "Periplaneta americana." (PR)

Provides instructions for teachers and students to culture protozoans for use in science laboratories. Sections include setting up a culture area, basic culture media, amoeba culture technique, powdered milk-wheat-rice medium, alfalfa medium, and uses of the protozoa in the laboratory. (PR)

Describes a technique to isolate unsheared bacterial DNA and subject it to restriction endonuclease enzyme digestion. (MDH)

Describes the development and implementation of state-of-the-art hardware and software for New Jersey's Kean University ESL Program, aimed at transforming the program into a model for computer-assisted interactive language learning. Discusses changes in students' language skills including production of more written language, frequent global…

Recommends the use of constructivist-based strategies to engage students who are not interested in science using traditional methods. Focuses on the application of these strategies in a laboratory experience exploring gas laws. (DDR)

Details a project in which students assess the health of two seemingly different streams by conducting chemical and biological tests. Focuses on student and teacher use of a watershed educational project in Tennessee. (DDR)
