This document consists of two modules. The first studies a variety of multicandidate voting systems, including approval, Borda, and cumulative voting, using a model which takes account of a voter's intensity of preference for candidates. The voter's optimal strategy is investigated for each voting system using decision criteria under uncertainty…

This document consists of two modules. The first of these views applications of algebra and elementary calculus to curve fitting. The user is provided with information on how to: 1) construct scatter diagrams; 2) choose an appropriate function to fit specific data; 3) understand the underlying theory of least squares; 4) use a computer program to…

Award winning projects in K-12 and college level economics are described in this publication. There are two major sections. Section I describes winning projects for 1979-80. A senior research seminar in economics offered undergraduate students a chance to build inexpensive, simplified forecasting models of the U.S. economy. Each student develops…

The reflections of two social scientists regarding an inservice education program for elementary school teachers were the basis of their approach to inservice programs: Teachers need to have analytical and inquiry skills that will allow them to read research reports and listen to inservice presentations, digest the information, and then apply what…

The results of an investigation of the development of children's knowledge of addition and subtraction concepts before they start school are detailed. The purpose of the study was to test the predictions of the three-stage model about the distinctions between the last two stages. Twenty-four children participated in the investigation. None of…

The Netherlands has an effective training system for secondary school administrators, in spite of an outwardly complex and compartmentalized education system. Nearly one-third of the schools are Roman Catholic, one-third Protestant, and one-third run by municipalities and by private boards. There is increasing emphasis on the growing complexity of…

The proposed research will thoroughly document the experiences of a small number of fifth grade children in an elementary school computer laboratory using LOGO, an advanced computer language designed for children. This documentation of a LOGO learning experience will offer specific information about the use of current advanced educational…

This document focuses on the use of a computer and the LOGO programing language by an eight-year-old boy. The stepping of variables, which is the development and incrementally changing of one of several variables, is an idea that is followed in one child's mind as he effectively directs himself in a freely-chosen problem-solving situation. The…

Presented are ways to teach pupils the concept of "sphere" with a methodology far removed from memorization of a formal definition of the concept. The material illustrates an approach to teaching that focuses on open exploration of ideas with children. Many experiments and starting points for exploration are suggested. This document has…

Problems were presented to 13 university students in which letters were to be added or subtracted (e.g., B + D = ? or F - ? = D). After each problem, each subject gave a retrospective protocol indicating the way in which the problem was solved. Models of performance by each subject in each experimental session shared major properties; choices by…

This compilation of reprinted activities is organized into five sections around the following topics: computational skills, calculators, geometry, measurement, and problem solving. The "Activities" section has been a regular feature of the Mathematics Teacher since 1972, and space limitations prohibited the inclusion of all previously published…

Of all the uncertain problems which curriculum theorists encounter, teaching curriculum to graduate students is among the most problematic. On the one hand is the mass of knowledge and concepts about curriculum. On the other hand is the student who, more often than not, has limited experience in putting abstract ideas to practical use. If the…

This paper describes a program providing support, education, and skill-building within a self-help format for the children of aged parents. The selection of the 18 initial program members, each with relatives living either in their homes, in a nearby location, or in nursing homes is reviewed. The 90-minute group sessions which met weekly for 8…

This paper presents a problem-focused needs assessment process for use by student affairs personnel. A comprehen- sive perspective of the needs assessment process is recommended, which views needs assessment as a necessary step in program planning, implementation and debriefing. Five types of needs assessment are identified and explained: (1)…

This report describes a study of two small-to-middle-sized midwestern school districts, each observed for about one year. The aim was to clarify the nature of the organizational form of school systems and to examine the organizational processes, using qualitative rather than quantitative methods. Two central concerns of the study were to explore…
