Marston, Paul T., Borich, Gary D. – 1977
The four main approaches to measuring treatment effects in schools; raw gain, residual gain, covariance, and true scores; were compared. A simulation study showed true score analysis produced a large number of Type-I errors. When corrected for this error, this method showed the least power of the four. This outcome was clearly the result of the…

Staskey, Paul J., Ed. – 1980
Proceedings of the 1980 annual forum of the Association for Institutional Research (AIR) on the topics of meeting the challenges of the eighties by redirecting resources for renewal are presented. Contents include the following addresses: "Planning: An Adaptive Process," by Barbara S. Uehling; "Catastrophe Models in…

Wolfle, Lee M. – 1979
Structural equation models incorporating unmeasured variables make possible the rigorous testing of theories previously difficult to test adequately because of fallible measures of the theoretic variables. This paper first discusses a simple causal model; incorporating a single unmeasured variable for the purpose of exposition. A substantive…

Griffiths, Alan K.; Cornish, Alan G. – 1978
This paper reviews methods which have been used to identify and validate learning hierarchies. Specifically, three methods which reflect the notion of a relatively inviolate sequence are discussed and compared. Two of the psychometric methods compare pairs of skills, the ordering-theoretic method (Bart and Krus) and the test of inclusion (White…

Sagaria, Sabato D.; Di Vesta, Francis J. – 1978
The relationship between placement of adjunct questions in instructional material and incidental and intentional learning was investigated. A total of 150 undergraduate students assigned to five experimental groups studied ten paragraphs with questions interspersed at different locations in the text. Performance on incidental items was…

Boxall, Ron; And Others – 1979
This paper is designed to provide teachers with more guidance on how to help students become proficient in the recall of basic number facts. Activities and practices are placed in a sequence designed to aid all instructors. The learning of number facts is divided into three stages: (1) the development of basic number facts; (2) establishing number…

Weiss, David J., Ed. – 1980
This report is the Proceedings of the third conference of its type. Included are 23 of the 25 papers presented at the conference, discussion of these papers by invited discussants, and symposium papers by a group of leaders in adaptive testing and latent trait test theory research and applications. The papers are organized into the following…

Haebara, Tomokazu – 1980
This study develops a weighted least squares method for transforming a logistic scale in such a way that the estimates of ability parameters on the tranformed scale are as comparable as possible with those on another scale. This scale tranformation process is referred to as equating of scales. Equating is an important procedure in studies…

Haladyna, Tom; Roid, Gale – 1980
The problems associated with misclassifying students when pass-fail decisions are based on test scores are discussed. One protection against misclassification is to set a confidence interval around the cutting score. Those whose scores fall above the interval are passed; those whose scores fall below the interval are failed; and those whose scores…

Echternacht, Gary – 1979
The role that measurement error plays in the regression effect is discussed with particular reference to the RMC models for evaluating the effects of Elementary Secondary Education Act Title I programs. The norm referenced evaluation model assumes a theory of growth where the relative ranking of students remains the same from pretest to posttest…

Wilcox, Rand R. – 1979
Mastery tests are analyzed in terms of the number of skills to be mastered and the number of items per skill, in order that correct decisions of mastery or nonmastery will be made to a desired degree of probability. It is assumed that a random sample of skills will be selected for measurement, that each skill will be measured by the same number of…

Folsom, Ralph E., Jr. – 1975
This memorandum demonstrates a variance components methodology for partitioning the overall design effect (D) for a ratio mean into stratification (S), unequal weighting (W), and clustering (C) effects, so that D = WSC. In section 2, a sample selection scheme modeled after the National Longitudinal Study of the High School Class of 1972 (NKS)…

Koch, William R.; Reckase, Mark D. – 1979
Tailored testing procedures for achievement testing were applied in a situation that failed to meet some of the specifications generally considered to be necessary for tailored testing. Discrepancies from the appropriate conditions included the use of small samples for calibrating items, and the use of an item pool that was not designed to be…

National Advisory Commission on Libraries, Washington, DC. – 1967
Both an analysis of the sources of cost trends in libraries and the relationship of the prospective role of automation in library operations to the causes of cost trends and the predicted shortage of trained librarians are examined in the study of the economic structure of the library. Issues investigated are those particularly relating to current…

Peaker, Gilbert F. – 1975
This is one of nine volumes describing the results of extensive research carried out by the International Association for the Evaluation of Educational Achievement (IEA) over a seven-year period. The overall aim of this extensive empirical study is to relate student competence to instructional, economic, and social factors which account for…
