The problem of forecasting monthly demands for library network services is considered in terms of using forecasts as inputs to policy analysis models, and in terms of using forecasts to aid in the making of budgeting and staffing decisions. Box-Jenkins time-series methodology, adaptive filtering, and regression approaches are examined and compared…

The Vocational Instruction, Training and Assessment (VITA) Project conducted a study to determine whether a battery of tests used with a sample of handicapped students enrolled in vocational education program(s) could aid in predicting success in vocational training. Procedures, instruments, and student samples were selected to provide data on (1)…

Items from a widely used standardized reading achievement test were rated by trained judges according to the degree to which they required an understanding of hierarchical classification. Two subtests were constructed from subsets of items that were identified by their extreme ratings. Subtest A was judged to require classification operations from…

This study investigates the relationship between auditory and visual acuity and the learning of first grade reading and spelling. It was the aim of this study (1) to clarify the relationship between auditory and visual perception; (2) to investigate the ability of subjects to read and spell when, and if, differences exist in the perceptual…

The forty minute Remote Associates Test (RAT) is designed to measure individual differences in an ability considered to be fundamental to the creative thinking process. It is based on a strictly associative interpretation of this process, an interpretation which envisions the process as one of seeing relationships between seemingly mutually remote…

The two-phase study compared two methods of adapting self-instructional materials to individual differences among learners. The methods were compared with each other and with a control condition involving only minimal adaptation. The first adaptation procedure was based on subjects' performances on a learning task in Phase I of the study; the…

This study was designed to: (1) investigate the relationships between internal-external (I-E) locus of control and academic achievement for boys and girls over a nine-month period and (2) to determine whether the moderate ability of I-E scores to predict academic achievement is due to the moderate reliabilities of the I-E measures. A total of 279…

This paper presents an empirical analysis of the real internal rate of return to the old age insurance (OAI) portion of the old age, survivors, and disability insurance (OASDI) program for worker-only beneficiaries retiring between 1967 and 1970. Section I reviews the analytical background for this study. The issues concern alternative measures of…

Investigations about attitudes toward mathematics carried out in the past decade were revised. The instruments used to measure attitudes toward mathematics were analysed as well as the attitudes toward different aspects of mathematics, their relation with other school subjects and their stability through time. Opinions about the influence of…

Since problems associated with the statistical methodology of educational research are becoming increasingly important, this paper examines a subset of problems associated with the analysis and interpretation of aggregated data. Two major questions arise: (1) if a researcher knows the level (e.g., individual, teacher/classroom, school, school…

The primary use of the Tests of General Educational Development (GED) is to appraise the educational development of adults who have not completed their formal high school education. The significance of these tests for higher education lies in their extensive use in admission of non-high-school-graduate adults to college. This study has three major…

This paper deals with two fundamental problems that are embedded in the evaluation of school practices: (1) attributing value to outcome measures, and (2) attributing outcomes to particular practices. Ways of generating evidence regarding the value of an outcome are discussed, particularly longitudinal research that clarifies the causal relations…

The prediction of creativity is an intricate and difficult problem for which there is no currently accepted method of solution. At least two conceptually discernable types of creativity are identifiable in research on the topic. The first type conceives creativity to be a trait which is distributed across the population in a fashion analogous to…

Studies pertaining to community growth have dealt with the community's territorial expansion, economy, government's functions, and institutions. Since researchers usually use the dimension that they have been taught (economists use economic measures, and social scientists use sociological measures), two problems have resulted: (1) How should…

A longitudinal study was undertaken to determine whether measures that are readily available in most school districts, administered in kindergarten by classroom teachers, could predict reading achievement as measured by standardized tests in grades 1 through 4. The subjects were 553 children in the kindergarten class of 1964-65 in Ithaca, New…
