Language for success in curricular and extracurricular contexts shows a range and complexity beyond the scope of most secondary school ESL programs in Canadian schools. The subject-specific language structure, rhetoric, and vocabulary for secondary level geography, history, and science are used as examples. (MSE)

National Association for Research in Science Teaching (NARST) members (N=101) responded to a 1979 survey, listing 398 statements of needed research. Three categories of needed research emerged as the greatest concern of these NARST members: instructional strategy, learning, and student/teacher attitudes. (Author/JN)

Outlines a variety of laboratory procedures, demonstrations, and classroom materials including a technique for estimating speed of electromagnetic waves; a support for multipin components when soldering; use of dynometer to measure force; bending light; using a microcomputer to measure and produce voltage; force-distance curves; and two games.

Describes equipment, activities, and experiments useful in chemistry instruction, including among others, a rapid method to determine available chlorine in bleach, simple flame testing apparatus, and a simple apparatus demonstrating the technique of flash photolysis. (SK)

Describes equipment, activities, and experiments useful in physics instruction, including among others, a list of articles relating to physics topics, computer interface that makes a computer cost effective, use of a guitar in vibrating string experiments, and photoelectric aids to the measurement of distance, speed, velocity, and acceleration.…

Despite rising enrollments, college biology education has until recently lagged behind other science disciplines in reforming undergraduate instruction. However, new approaches are emerging, including introductory classes that focus more on concepts, laboratory assignments that are increasingly sophisticated, and more in-depth curricula for…

Provides seven fully developed library media activities that are designed for use with specific curriculum units in mathematics, reading and language arts, science, and social studies for elementary and secondary education. Library media skills, objectives, grade levels, resources, instructional roles, evaluation, and follow-up are described for…

Describes how a unit on drinking water from the Association for Science Education's (ASE) project, Science across Europe, is used as the basis for incorporating assessable key skills into GNVQ Science assignments. Provides examples of worksheets and data analysis. (DDR)

This article reports on an interactional ethnographic study of three professional-development conversations on the participation of students with special needs in guided inquiry science instruction. It focuses on how teachers' thinking about the use of small-group work changed over the course of the conversations and led to modifications in…

Evaluates two Apple II interfacing packages designed to measure pH: (1) "Experiments in Chemistry" by HRM Software and (2) "Voltage Plotter III" by Vernier Software. Provides characteristics and screen dumps of each package. Reports both systems are suitable for high school or beginning college laboratories. (MVL)
