A new system of order analysis, developed by Takeya and called Item Relations Structure Analysis (IRSA), was described and used for examining the structural relations among a set of 24 items on the addition and subtraction of fractions. A diagraph showing 16 chains of items that had discernibly common features was generated by this method, and…

Twelve research reports related to mathematics education are abstracted and analyzed. Three of the reports deal with aspects of learning theory, two with student characteristics, and one each with calculators, problem solving, secondary mathematics curriculum changes in Australia, sex differences, teaching methods, and tutoring strategies. The…

These teacher developed case studies taken from the business world are presented to help secondary students develop an understanding of economics and of the decision-making process. The studies describe real business situations. All historical and current facts are provided, and students must analyze the data and make business decisions. Teacher…

The involvement of process consultants can ease the development of strategies for increasing school effectiveness. The process consultant does not function as an expert in education, but facilitates development of an effective planning team consisting of the principal and four or five faculty members. The consultant first determines whether the…

This study was conducted to identify types of interactions associated with social influence among school children at three grade levels. Social influence was defined in terms of the ways in which a child attempted to convince other group members to adopt his or her opinions about the appearance of three different inkblots. Eighteen kindergarten,…

A work-scheduling model for Corrections Officers at State Correctional Institutions is described. This is a real-life model that was developed to deal with a problem of unacceptably large expenditures for overtime work by state prison guards. The problem involves more than 200 constraints and more than 800 variables. It is felt the model can be…

Models of the motion of an object through space are discussed. The material begins with the simplest view possible in which gravity is the only force examined. Discussion progresses to an examination of the drag force, which is the resistive air force of the wind. Suggestions for further improvements are made at the conclusion of the presentation.…

These modules view aspects of computer use in the problem-solving process, and introduce techniques and ideas that are applicable to other modes of problem solving. The first unit looks at algorithms, flowchart language, and problem-solving steps that apply this knowledge. The second unit describes ways in which computer iteration may be used…

The material looks at: 1) Choosing a Clinical Test; 2) Evaluation of Diagnostic Tests; 3) Multi-Disease and Multi-Test Analysis; and 4) Medical Decision Analysis. It is felt users will be able to: 1) calculate the predictive value of a positive or negative test result in model clinical situations; 2) estimate the sensitivity and specificity…

This document consists of four units. The first of these views calculus applications to work, area, and distance problems. It is designed to help students gain experience in: 1) computing limits of Riemann sums; 2) computing definite integrals; and 3) solving elementary area, distance, and work problems by integration. The second module views…

The author contends that families are uniquely constituted to bestow the gifts of caring, courage, and problem solving ability upon children. Clinical and epistemological insights as well as research evidence concerning child development and family relationships are presented as sources of information which will aid families to bestow these gifts.…

The learning of word problems in mathematics is viewed as particularly difficult. The first paper in this report takes into consideration the semantic aspects of problems, by viewing the difficulties that children have solving two-step multiplication problems. An initial study was carried out with 36 children between the ages of nine and fourteen…

This K-12 social studies curriculum guide was developed to provide local schools in South Dakota with a point of departure for their own curriculum development. There are five sections to the guide. Section one, "Social Studies Standards of Excellence," discusses shared decision making and commitment, community support for the social studies,…

It is often assumed that old age is a time of numerous losses, irritants, and stress. Although researchers have examined the interrelationship of stress, health, and happiness in old age, stress is usually operationalized as a response to major life events; however, stress can also be operationalized as a response to the everyday experiences of…
