Describes video distribution systems as a way of giving control of all monitors in a classroom to the teacher. Examples of their use are given, including distribution in language labs and distribution from a media lab to classrooms throughout a school building; and information about five vendors is included. (LRW)

Describes the Virtual Reality and Education Lab (VREL) established at East Carolina University to study the implications of virtual reality for elementary and secondary education. Highlights include virtual reality software evaluation; hardware evaluation; computer-based curriculum objectives which could use virtual reality; and keeping current…

Presents pendulum lab results as an example for students on the write-up of experiments. (PR)

Emphasizes the importance of paying attention to how writers feel about their writing as well as what they think about it. States that textbooks deal with writers' feelings incidentally. Defines "flow" as being the opposite of writer's block. Defines "liking" and its implications for a writer's work-in-progress. Asks whether…

Includes "Managing Personality Types in the Computer Classroom" (Cocco); "External I/O Input/Output with a PC" (Fryda); "The Future of CAD/CAM Computer-Assisted Design/Computer-Assisted Manufacturing Software" (Fulton); and "Teaching Quality Assurance--A Laboratory Approach" (Wojslaw). (SK)

This photosynthesis exercise is intended for introductory college biology or botany courses. It is based on the principle that a closed suspension of algal cells may be expected to produce more dissolved oxygen with a greater photon fluence rate, but within limits of the photosynthetic capacity of the system. Describes materials and methods. (LZ)

Describes safety hazards encountered when placing squash balls into liquid nitrogen. Suggests using racquet balls, balloons, or economical Ping-Pong balls. (MVL)

Describes the development of the Science Laboratory Environment Inventory (SLEI) instrument for assessing perceptions of the psychosocial environment in science laboratory classrooms, and reports validation information for samples of senior high school students from six different countries. The SLEI assesses five dimensions of the actual and…

An inexpensive way to foster interactive, participatory learning in the language laboratory through communicative tasks is described. Problems with traditional approaches are discussed, and enthusiastic reactions from both students and teachers to the University of Maryland-College Park multimedia approach are reported. (39 references) (LB)

Describes the electrical and material characteristics of a wide variety of sensors and switches, as well as methods for connecting them to computers that are equipped with a joystick interface. Includes a BASIC computer program that facilitates automation of science experiments and storage of data gathered with simple transducers and sensors.…

Provides a step-by-step guide for a simple experiment to measure the approximate percentage of oxygen found in the air that we breathe. Includes background theory, working drawings, chemicals needed, list of supplies, experimental procedure, data evaluation method, and suggestions for extended study. (Author/JJK)

Presents recent changes in the technology, expansion of courseware, and distribution to other institutions of the interactive videodisc courseware utilized as a significant part of the undergraduate chemistry curriculum at the University of Illinois since 1986. (JJK)

Authors describe a biology course for nonmajors that appealed to student interests while retaining content integrity. The other philosophical foundations of the course were to increase student involvement and to conduct at least half of the laboratory aspect of the course at field-based locations. Details of transportation considerations,…

Describes the study of sandy beach zonations as a seashore activity for either high school or lower-level college courses in biology, ecology, or marine biology. Students first draw a profile of a beach scene and then collect specimens from the zones of the shore. In a laboratory, students identify their specimens and relate them to the beach…

Reports study of college biology laboratory course where 604 students were placed in pairs based on their scientific reasoning ability (intuitive, transitional, reflective). Results indicate no significant difference between type of partner and laboratory score or posttest reasoning score. Survey results indicate reflective partner was viewed as…
