This report presents statistical analyses of data derived from the first year's use of the Instructional Assessment System. Included are: means, standard deviations, and several reliability estimates for each item within each form; inter-item correlations; and correlations of items with non-evaluative variables. Among the major results discussed…

The relationship between occupational status projections and subsequent occupational attainment is analyzed through a comparison of the occupational aspirations and expectations of 614 tenth grade students in 1966, and their occupational status attainment in 1972. Aspirations, expectations, and attainment were the variables measured, using the…

Papers and discussants' comments from a symposium on issues concerning infants' reactions to strangers are presented. Researchers agreed that there is a developmental shift in infant behavior at 7 to 9 months of age when the infant becomes more cautious in approaching strangers. However, investigators hypothesize that the presence of the mother,…

This study empirically determined the optimizing weight to be applied to the Wrongs Total Score in scoring rubrics of the general form = R - kW, where S is the Score, R the Rights Total, k the weight and W the Wrongs Total, if reliability is to be maximized. As is well known, the traditional formula score rests on a theoretical framework which is…

Of 391 living participants in the 10-year-old Academic Administration Internship Program (AAIP), 320 or 82 percent completed the questionnaire, which became the basis of this evaluation study. Survey data were used to determine the current status of the AAIP alumni and fellows, the usefulness of the AAIP experience in their careers, the national…

The Mastery-Learning test model is extended. Methods for estimating prior probabilities are described. The use of an adjustment matrix to transform a probability of mastery measure and empirical methods for estimating adjustment matrix parameters are derived. Adjustment matrices are interpreted as indicators of instructional effectiveness and as…

The Rasch item analysis model is supposed to yield norm-free estimates of ability and easiness values, but there are several possible interpretations of the nature and extent of such norm-freeness. One such interpretation was that to involve the scores of one single experimental group of testees which were embedded in four differently skewed…

The three objectives of this study were: (1) To investigate the changes in different teaching behaviors effected by different instructions alone, training alone and the interaction between them when they are combined; (2) To reveal the structure of interrelations among classroom activities, classified according to two category observation systems,…

This report summarizes test performance for 771,031 students tested on Armed Services Vocational Aptitude Battery (ASVAB) Form 2 during school year 1973-74, with separate normative tables provided by sub-test, aptitude composite, grade, sex and geographic region. New data are provided for ninth grade and post-high school students. Information…

The project focuses on two loosely-related hypotheses regarding a contradiction existing in the results of previous research on the relationship between labor force participation and unemployment. This contradiction is the persistent tendency of the estimated effect of unemployment on labor force participation--and hence estimates of "hidden…

The Instructional Improvement Questionnaire (IIQ) is a student rating form designed to provide evaluative feedback to instructors about their teaching. The IIQ was first developed at Southern Illinois University at Carbondale in 1969 and revised in 1972. The documents included here describe the development of the IIQ and research associated with…

Curriculum innovation and research in the dental medicine field is addressed as a major area of concern to those faced with pressures to provide more efficient and effective health care services. A survey was undertaken to determine (1) the type of training and background desired and (2) recruitment procedures and employment prospects for persons…

The academic performance during Fall 1972 of regular admits, scholarship award winners, and disadvantaged students admitted under the exceptions admissions policy at the University of Maryland Baltimore County is analyzed. Comparisons are made of the effect of tutorial assistance provided by the UMBC Learning Resources Center upon the grade point…

Assessment exercises (items) in three different formats--multiple-choice with an "I don't know" (IDK) option, multiple-choice without the IDK, and open-ended--were placed at the beginning, middle and end of 45-minute assessment packages (instruments). A balanced incomplete blocks analysis of variance was computed to determine the biasing…

This project is concerned with the development and implementation of some new statistical techniques that will facilitate a continuing input of information about the student to the instructional manager so that individualization of instruction can be managed effectively. The source of this informational input is typically a short…
