HIGH SCHOOL CHEMISTRY UNIT TESTS AND A PRETEST DESIGNED TO PREDICT STUDENT SUCCESS ON A STATE CHEMISTRY EXAMINATION WERE CONSTRUCTED. HIGH SCHOOL SCIENCE TEACHERS AND UNIVERSITY SCIENCE EDUCATORS USED BLOOM'S TAXONOMY OF EDUCATIONAL OBJECTIVES TO CLASSIFY TEST QUESTIONS ACCORDING TO THE DEGREE THAT THEY INVOLVED RECALL, COMPREHENSION, APPLICATION,…

This instructional program is designed to be used with grade 10 students for 4 to 5 weeks to help students to predict what will happen in a given energy situation. It is designed to lead students to an understanding of their personal energy use, to a realization of the moral nature of the assumptions underlying energy decisions, and to a belief…

Describes a survey of 19 British high schools that revealed the students' low level of understanding of ionic chemical equations. (MLH)

Presents data on the readability of periodicals and textbooks commonly used by students studying school agriculture. (GS)

Provides tables and graphs that give a complete and simple picture of the relationships of image distance, object distance, and magnification in all formations of images by simple lenses and mirrors. (CP)

Describes some science apparatus: included are a gene kit to demonstrate aspects of population genetics and selection, an electronic thermometer for use in the field of environmental studies, an astrobrella to use in astronomy classes, and crystal display models of different substances for chemistry classes. (GA)

Presents a summary of letters presented at the Australian Academy of Science annual symposium. (SL)

Presents part eight of a continuing series on the exponential function in which, given the current population of the Earth and assuming a constant growth rate of 1.9 percent backward looks at world population are made. (SL)

Discusses seven different teaching methods for presenting secondary level chemistry. (SL)

Describes selected activities from the Technology-People-Environment (TPE) curriculum designed to improve the technological literacy of secondary school students. (SL)

Described is a novel approach to the teaching of projectile motion of sixth form level. Students are asked to use an analogue circuit to observe projectile motion and to graph the experimental results. Using knowledge of basic dynamics, students are asked to explain the shape of the curves theoretically. (Author/MA)

Describes chemistry programs in four Australian secondary schools. (CP)

Discusses the technique of utilizing "silent" demonstrations, demonstrations with a minimal of instructor initiated information, for teaching secondary level chemistry. (SL)

Describes an "environmental biology" syllabus offered to third year students at Ounsdale Comprehensive School. Six project areas are described: an individual investigation, a plant project, human biology, rural science, habitat surveys, interdependence. (CS)

Discusses limitations and corrections to be made in physics experiments involving the investigations of drag and terminal velocity on spheres falling through a liquid in accordance with Stokes' law. (SL)
