Provided are background information, equipment lists, and procedures for four activities for teaching aquatic ecology. Activities include "The Aquatic Food Chain Game"; "Two-Liter Aqua-Vivariums"; "A Sealed World"; and "Weaving a Web: Evaluation." (CW)

Contains articles on digestive enzymes in grasshoppers; bird and badger observation; reactions between hydrochloric acid and sodium carbonate solutions; observing the migration of ions; pupil's heating skills (Bunsen burners); photolysis experimentation; capillary kinetics; experience with trireme; connection circuits; special relativity; a…

Five articles describe improvements in instructional software designed to enhance problem solving skills. Issues addressed include problem solving software to implement curriculum goals; problem solving theory and writing theory; software for elementary and secondary school science instruction; software for mathematics instruction; and cognitive…

A model for introducing English-as-a-Second-Language learners to the language laboratory component of a modern "Language Acquisition Resource Center" (LARC) at a metropolitan university is presented. Emphasis is on audio materials, but many of the LARC suggestions are applicable to video and computerized materials as well. (Contains 16…

Indiana University's Teacher Education Laboratory replaces and supplements portions of the preservice program previously provided through field placements in area schools. This article describes the initial field test of a laboratory experience for secondary education majors. Surveys rating students' attitudes about the experience indicated…

A computer-based replacement for an electronics laboratory experiment was created and tested on second-year undergraduate students in the Department of Mechanical Engineering at the University of Southampton (England). Responses, assessed by questionnaire, showed that computer-assisted learning techniques provide a viable means for teaching…

Describes a project to develop and conduct an assessment that was congruent with the hands-on, process-oriented science education used in an Illinois school district. The approach used observations, group-teacher interactions, group performance, and data gathering and interpretation. The major components of the program are summarized. (PR)

Describes techniques and equipment which allows school microscopes to perform crossed-polarized light microscopy, reflected light microscopy, and photomicrography. Provides information on using chemicals from a high school stockroom to view crystals, viewing integrated circuits, and capturing images on film. Lists possible independent student…

Argues that educational computing is a discipline and discusses issues that need to be addressed in this discipline, including similarities with experimental psychology; networks and integrated learning systems; problem-solving software versus domain-specific software; computer labs versus classroom integration; software quality; computer equity;…

Presents experiments to measure the velocity of sound through metals and other amorphous materials. Describes the equipment used to make the measurements and the possibility of interfacing with a microcomputer. (MDH)

Describes the growth of Lac Courte Oreilles Ojibwa Community College's science and technology programs through grants which have funded new faculty positions, the construction of new science and computer facilities, 16 computers, and the implementation of long-distance learning systems. (DMM)

Describes a teaching technique that uses word processing software to automate the process of providing feedback about psychology assignments in a microcomputer-based laboratory course. Automation of the feedback process is explained, benefits to students and instructors are discussed, and student reactions are reported. (six references) (LRW)

A high school teacher created a writing center for private student peer tutorials without a teacher. Students borrowed some tutoring methods from the teacher and devised some rules and strategies of their own that led to a more socially constructive environment in which they were more enthusiastic about their writing.

A study of the relative effectiveness of an introductory activity to teach intracoronal operative preparations to dental students (n=35) found that in comparison with traditional classroom methods used with 29 students, the leadup activity resulted in more efficient instruction and improved learning. Amount of teacher supervision was also a…

The results of an in-depth analysis of the lab activities found in two popular high school biology textbooks are presented. Activities were rated against 24 task categories that parallel skills or behaviors which reflect scientific inquiry, problem-solving skills, manipulative skills, and observational skills.
