This is the second edition of a curriculum guide for secondary school mathematics. It is one of a series intended to serve as a model for Alaskan school districts as they develop and review their curriculum documents. Listed are topics and concepts, learning outcomes and objectives, and sample learning activities. The learning activities are…

This paper briefly demonstrates a few of the possibilities of a systematic application of robustness theory, concentrating on the estimation of ability when the true item response model does and does not fit the data. The definition of the maximum likelihood estimator (MLE) of ability is briefly reviewed. After introducing the notion of…

Traditionally, the errors-in-variables problem is concerned with the point estimation of the slope of the true scores regression line when the regressor is measured with error, and when no specification error is present. In this paper, the errors-in-variables problem is extended to include specification error. Least squares procedures provide a…

Given that comparative/contrastive arguments can be displayed separately in a text (one complete argument followed by another, or O-organization) or in an integrated way (with the various aspects interleaved, or A-organization), a study compared a third arrangement--a graphic format, or G-organization--that presented the two descriptions side by…

This study addressed the question of whether teachers' judgments differ according to the frequency of data collection on student performance and the type of trend. The study also investigated whether teachers' judgments, based on different types of graphs (ascending, descending, flat, or variable), vary with the frequency of data collection. A set…

Twenty-eight engineering students were presented with complex spatial problems to investigate the effects of spatial aptitude and strategy selection on problem solving. Aptitude was determined by spatial aptitude test scores and strategy was determined by verbal reports and latency measures. It was found that aptitude determined the efficiency…

Utah's Minimum School Finance Program provides for the funding of several component programs. This document reports on these component programs, describing their characteristics and objectives and displaying graphically the recent statistical data revealing their extensiveness, their costs, and trends in their utilization. The report first…

Data collected by the Association of Research Libraries (ARL) in a survey of salaries of library professionals for the fiscal years 1975-76 are analyzed. Tables and graphs display: (1) personnel distribution by salary level, 1974-76; (2) analysis of salaries at ARL university libraries, 1969-1976, comparing salary indices to consumer price…

School finance cases are relying increasingly on data analysis to show inequities. Such cases are based on the assumption that some state school finance systems are failing to achieve fiscal and educational equality. Data analysis can be used to show such things as the use of wealth as the primary determinant of a certain school district's…

Working from the premise that for any given periodical title there is some frequency of use at which it becomes cheaper for a library to acquire the publication than to borrow it, this report presents a mathematical model for estimating the costs of options associated with acquiring periodicals. Cost elements included in the model are initial…

This outline is for a pre-algebra course designed to prepare students for algebra or to satisfy a one-year mathematics requirement. A key purpose is to present a practical mathematical experience. A detailed outline is given with a suggested time allotment for each chapter. A discussion of each topic follows with teaching suggestions and examples.…

This module is primarily designed to focus on two main areas: graphing and map reading. Graphing entails the use of bar, line, and circle graphs, the x and y axes, the coordinate plane, and ordered pairs. Map reading includes conversion tables, approximations, devising scales, and learning to refold a folding map. (Author/MK)

This study attempted to determine the relationship between average daily attendance (ADA) and costs in 72 Illinois high schools having only one attendance center. Costs included administrative, instructional, and operational costs. The schools were divided into three populations, namely all those under 5,000 ADA, those less than 2,000 ADA, and…

Results of some of the Modern Language Association (MLA) Cooperative Foreign Language Tests, administered to students of Spanish, German, and French in grades 9-12 in the Pennsbury School District of Pennsylvania are compared with the national norms. Although most of the comparison is set up in tablees a summary of the analysis is included.…

In a series of three independent studies that focused on the classic sources of curriculum (the learner, society, and subject matter), data were gathered that might bear on the choices facing the curriculum developer. Learner data tentatively revealed what characteristics of pictures affected the deployment of third-grade children's visual…
