A series of outdoor activities is provided in which measurement and geometry are used to describe phenomena in the environment. (SD)

Seventeen studies of self-paced instruction in algebra, geometry, trigonometry, and college mathematics courses are reviewed. In general these studies did not find the individualized programs to be superior to theregular instruction with which they were compared. (SD)

A program in which Spanish-speaking high school students were taught basic number skills is described. The program was individualized, and used a variety of activities and materials. (SD)

Students collected and organized data concerning noise levels of various school activities. They reported that the activities were interesting and relevant. (SD)

Five activity lessons are proposed to present applications of probability and to exhibit its use in conjunction with statistics as a major decision-making and problem-solving tool. (MP)

An "inference can" is described, with two games that allow students to observe and predict events, define population, and draw samples. (MP)

Contained in this column are articles discussing the following topics: cross-number puzzles, an intuitive development of pi, a three-column proof format, and an easily constructed kit to be used in acquainting students with the wrapping function used in introducing circular functions. (MP)

This report on the Pennsylvania statewide assessment program answers two questions: (1) what are minimum competencies?; and (2) for whom are competencies really minimal? (Author/MP)

The construction of tables of numbers is discussed as a learning activity that involves work in such things as reciprocals, calculators, formulas, patterns, discovery, prime numbers, and other types of numbers. (MP)

A problem from number theory is used to illustrate the use of the computer and programable calculators in solving problems. Programs are included. (MP)

Students use a series of isosceles right triangles constructed on a geoboard to discover patterns and form generalizations. (MP)

Thirty-five secondary school children were interviewed on a one-to-one basis using questions which involved concepts considered as basic to the notion of ratio. One implication of the study is that a doubling ability is no indication of the ability to tackle other ratio questions. (MN)

This discussion focuses on the problem computer users have in coding basic, traditional algebraic expressions into simple, all-on-one-line expressions as result of their heavy dependence on juxtaposition notation. (MN)

The construction of a measurement device to determine elevation is described. Activities for use with the device for upper elementary and secondary students are included. (CP)

No significant interaction was found between two instructional treatments and two aptitude variables in this study, but they did find four disordinal interactions, two using one predictor variable and two using two predictor variables. (MN)
