This module on statistics consists of 18 worksheets that cover such topics as sample spaces, mean, median, mode, taking samples, posting results, analyzing data, and graphing. The last four worksheets require the students to work with samples and use these to compare people's responses. A computer dating service is one result of this work.…

The scoring scheme of the National Assessment of Educational Progress (NAEP) is studied, as well as techniques for estimating its reliability. NAEP data are collected on students of age 13 in the fall, age 9 in the winter, and age 17 in the spring. The scoring task, involving hand scoring of open-ended items, may vary between 25,000 responses to…

This guide presents a classroom problem solving model designed to help teachers conduct their own classroom research. It suggests developing a procedure for identifying the instructional problems influencing reading achievement. The model is presented in steps that can be used independently or in concert with other steps. Practice activities are…

The development of content analysis instruments sensitive to the instructional, social, and value-laden content of a television series, was necessary because of formative evaluation needs to establish the congruity of the actual program content with the intended content and to assess the hidden curriculum. Because issues ranged widely, four…

Intended as a reference for the convenience of students in sampling, this monograph attempts to express relevant, introductory mathematics and probability in the context of sample surveys. Although some proofs are presented, the emphasis is more on exposition of mathematical language and concepts than on the mathematics per se and rigorous proofs.…

This report is intended to provide government managers with some perspective on the nature and implications of sample surveys, their likely costs, and what can be expected from them. The authors discuss sample surveys less from the technical side than from the perspective of the officials who will make management decisions about an overall survey.…

This report presents the findings of a research study, conducted by the College of the Mainland (COM) as a subcontractor for Project FOLLOW-UP, designed to test the accuracy of random sampling and to measure non-response bias in mail surveys. In 1975, a computer-generated random sample of 500 students was drawn from a population of 1,256 students…

The literature on criterion referenced testing is full of discussions concerning whether classical measurement techniques are appropriate, whether variance is necessary, whether new indices of reliability are needed, and the like. What appears to be lacking, however, is a clear and simple discussion of why the problems occur. This paper suggests…

Georgia's Needs Assessment Package, which has many sample forms, includes a procedure which helps to identify short-range and long-range educational needs. This procedure utilizes community participation which broadens the decision-making base and serves to legitimatize actual decisions. It utilizes the opinions of professional educators,…

The study, prompted by a concern for the ineffectiveness of prison education programs to improve the educational level of inmates, was conducted for the purpose of investigating the effects of short term or extended tasks and financial incentives on the educational activity and achievement of the young prison inmates. The sample consisted of…

This study examines a set of hypotheses relating obsolescence to career patterns, professional activities, and certain aspects of the organizational climate in an attempt to discern the dynamics of obsolescence among graduate engineers in the United States. Based on a sample, two measures of technical obsolescence were used. One involved the…

The paper reviews the research on design and operation of research libraries sponsored by the Purdue University Libraries and the Purdue School of Industrial Engineering. The use of mathematical models in library operations research is discussed. Among the mathematical methods discussed are marginal analysis or cost minimization, computer…

The purpose of this study was to estimate the reliability of various measures of writing behavior using 500-word samples instead of 1000-word samples. The themes of 135 eighth graders on narrative and expository topics were collected for 6 weeks, one theme per week. Samples of at least 1000 words were obtained from each student, and the criteria…

Classroom Teacher Support System (CTSS) is a prototype system for computer-assisted construction and scoring of tests, using questions from a central data bank. The computer programs for CTSS were developed by International Business Machines Corporation for study in the Los Angeles City Unified School District in 1969 and 1970. In order to provide…

Incorporated in the media evaluation model developed by the Computer Based Project (Syracuse, N.Y.) is a procedure whereby independent samples are used to obtain baseline responses to cognitive question items. Items from two films are intermixed and presented after showing only one of the films; thus, the sample audience responds to questions from…
