It is sometimes desirable to obtain an estimated total-test score for an individual who was administered only a subset of the items in a total test. The present study compared six methods, two of which utilize the content structure of items, to estimate total-test scores using 450 students in grades 3-5 and 60 items of the ll0-item Stanford Mental…

A procedural model is presented for the construction and validation of an attitude scale in vocational education; and the results of an instrumentation study using that model are discussed. The three-stage model is composed of: (1) stratification of the construct; (2) item construction and selection; and (3) item cluster analysis. In phase one,…

The evaluation model for mastery testing as proposed by Emrick (1971) represents an empirical approach to determining the most appropriate mastery criterion score that should be established in those testing situations which entail decision making relative to the continued progression or possible recycling of students in a given learning sequence.…

Latent trait test score theory is discussed primarily in terms of Birnbaum's three-parameter logistic model, and with some reference to the Rasch model. Equations and graphic illustrations are given for item characteristic curves and item information curves. An example is given for a hypothetical 20-item adaptive test, showing cumulative results…

The effect of stratified sampling of items on the estimation of test score distribution parameters by multiple matrix sampling was studied. Item difficulty and/or interitem correlations were the bases of stratification. Various item iniverses were created by computer simulation and sampled according to several plans. The results indicate that…

A general purpose computer program for the calculation of a matrix of tetrachoric correlations is described. This program was developed for use in adaptive (and other) testing research for examining the unidimensionality assumption in latent trait theory, in conjunction with available factor analysis programs. Several other potential applications,…

The study sought to define the Ethos of a classroom and its operating assumptions. The basic components of the Ethos variable are Authenticity (for individual students), Legitimacy (in terms of knowledge and societal disciplines), and Productivity (effectiveness of activities). This variable is referred to by its acronym, ALP. An international…

An important component of high quality data is the completeness of the gathered data. Complete response consists of 3 specific factors: (1) sample mortality (the loss of respondents from the initial sample); (2) item nonresponse; and (3) detail given to open-ended items. Responses to the personal interview among Mexican American migrants were…

To help teachers who must produce test items to measure instructional objectives, 54 teacher education candidates participated in an experiment where easily understood constraints on item production were manipulated. Four forms of a test item writing exercise sheet were randomly distributed, each asking for the production of eight sample test…

This device, a potential instrument for measurement of an important aspect of the worker--job relationship, was developed for use in guidance and counseling; personnel matters of business and industry; career, occupational, and vocational education; and in efforts to explore and validate the career ladders and lattices within occupational fields.…

Written by an ex-Latin teacher, short-cuts to analyzing test results for the non-mathematical teacher are provided. Discussions are given of item analysis (item analysis by a show of hands, standards for test items: success, standards for test items: discrimination, and the second stage of item analysis. The standard error is then presented (the…

Internal evidence of cultural bias, in terms of various types of item analysis, was sought in the Wonderlic Personnel Test results in large, representative samples of whites and Negroes totalling some 1,500 subjects. Essentially, the lack of any appreciable Race X Items interaction and the high interracial similarity in rank order of item…

Violations of four selected principles of writing multiple-choice items were introduced into an undergraduate religion course mid-term examination. Three of the flaws significantly increased test difficulty. KR-sub-20 values were lower for all of the tests containing the flawed items than for the "good" versions of the items but significantly so…

Four problems of data summary and analysis in the Concept Attainment Abilities Project are discussed. The problems are: (1) scoring and item analysis for items that exist in a completely crossed design; (2) determining the factorial structure of such item sets; (3) reducing the battery of 56 cognitive abilities tests administered in 1970 to…
