Examples of the presentation and solution of variations on a common projectile trajectory problem are presented. (BB)

Advance organizers may fail to promote learning even though they are approximately related to the main learning experience and internally meaningful and logical. If they are to optimize the likelihood that new materials will be readily and properly subsumed, they must also be constructed to conform to the cognitive preparedness and scholastic…

Pascal's triangle can be used as early as grades five and six to teach children to recognize mathematical patterns. Children can be guided to discover patterns or sequences of numbers if they begin with pictures or physical objects which they can manipulate and count. (Author/BB)

The introduction of prime numbers in the intermediate grades should be handled with care or the concept will appear arbitrary, artificial, and unreal to the pupils. The approach suggested here is in the form of a game-like activity. A knowledge of multiplication and factors is a prerequisite. (BB)

A look at science education in the next 25 years. Some of the factors and variables that may affect science programs are: a rapidly changing society, technological advances, the nature of the science teaching population, enrollment patterns in the student population, and new advances in the application of learning theory and teaching techniques.…

Games proved effective as an activity for reinforcing mathematical skills when used with five-year-old children in an open-area public kindergarten. (Author/BB)

SI units of work, force, and energy are identified. (BB)

This activity, for grades 7-12, requires students to lay out an arena for training horses. To do this the students compute the sum of metric linear measures, compute the circumference of circles and semi-circles, and use the Pythagorean Theorem. (BB)

The objective were to explore some of the ways in which the calculator can be used and to determine the effects. Areas covered are: computation, mathematics readiness, problem solving, and discovery learning. (MP)

Research results of several studies are used as a basis for suggesting some guidelines for teaching measurement concepts. Prerequisite concepts and skills are given emphasis. (MP)

The data show that biology teachers spend relatively little time on diseases of the cardiovascular system. Approximately one period per year is spent on each of eight given cardiovascular disease risk factors. (MP)

Discussed is literature related to sex differences in mathematical ability. Three causes for such differences are explored: biological, cultural pressures, and the process of sex-role identification. (MP)

The elementary school science curriculum program, Science Curriculum Improvement Study (SCIS), was investigated to determine effects upon students' attitudes toward science and perception of the science instruction. The data show favorable results. (MP)

General education mathematics for the undergraduate is discussed in terms of the general philosophy and attitude and how these can affect the learning situation. (MP)

A collection of errors in the physical sciences which occurred in communication media is reported. (MP)
