Presents the Morris Loe Angle Trisection Approximation Method to introduce students to areas of mathematics where approximations are used when exact answers are difficult or impossible to obtain. Examines the accuracy of the method using the laws of sines and cosines and a BASIC computer program that is provided. (MDH)

Suggests energy-related activities that represent different instructional approaches and can be adapted for different age levels. Includes library research, debates, role playing, games, and mock trials. Offers questions to be used in connection with the activities. Examines the future of energy use and international inequality of use. (DK)

Presents methods for teaching two mathematical concepts that utilize visualization. The first illustrates a visual approach to developing the formula for the sum of the terms of an arithmetic sequence. The second develops the relationship between the slopes of perpendicular lines by performing a rotation of the coordinate axes and examining the…

Utilizes a computer-generated graph to solve an equation for methods using trigonometric tables or less sophisticated calculators would likely fail because of round-off errors and limitations of the instruments. Discusses how this new technology can be utilized in mathematics instruction. (MDH)

Presented is a concrete, realistic way of representing concepts of coordinate geometry. Students represent the coordinates in a living version of a five-by-five square geoboard. Procedures and examples for using this activity are included. (KR)

Discusses "Mascots and Meanings," a research activity that helps give students a concrete concept of some of the elements of a region or place. Provides a list of professional and college sports mascots. Identifies strategies that call upon students to identify the reasons for the choice of the particular mascots. (SG)

Presents a method for simulating the behavior and perceptual deficits demonstrated by patients who have undergone the split brain surgical procedure. Presents several activities in which two volunteers are required to accomplish certain tasks as one person. Suggests that these activities show how split brain patients illustrate certain lateralized…

Describes a demonstration to illustrate the importance of knowing what is supposed to be learned before studying begins. Suggests that the exercise may be used to show the basic elements of a scientific experiment. Explains that attention's effect upon memory is shown by students' tendency to remember best what they are told to remember. (DK)

This article outlines the development of a nine-week communication skills program for elementary grades using a collaborative/consultative model. The program emphasizes social skills training and the importance of using good communication skills. The article outlines program development and procedures for teaching each concept. (DB)

Explains that Canadian general education is intended to prepare students for community college, whereas advanced education is meant to ready them for university study. Offers 25 strategies for teaching on the general level. Argues that the tips can improve the teacher student relationship and make any subject more interesting and enjoyable for…

Reports that the absence of a normative training document is a central principle of the former USSR's Tallinn School of Management. Identifies five common blocks of instructional improvisation: writing a business letter; communication; taking and maintaining control; production and operation management; and product distribution. Describes some of…

Examines results of a survey documenting the current state of adolescent programs in the Montessori schools of North America. Includes information on the students, adults, and physical environment of such programs, as well as the programs' enrollment, grouping, activities, and materials. (HTH)

Explored are the distributions of residual components in two model systems. A system of components with exponentially distributed lifetimes and the two-dimensional "leaf model" in which objects fall on a plane with positions independent and normally distributed are discussed. Included are the definition, application, computations, and theorem. (KR)

The problem of determining the most energy-efficient strategy to use in approaching a traffic light that is sighted at an unknown phase in its cycle is discussed. Included are calculations, results, and conclusions. (KR)

Presented is a combinatorial problem based on the Hash House Harriers rule which states that the route of the run should not have previously been traversed by the club. Discovered is how many weeks the club can meet before the rule has to be broken. (KR)
