Three classroom organizational schemes for presenting technical information in industrial arts were compared: (1) individual achievement in a small group setting with no teacher interaction, (2) group achievement in a small group setting with no teacher interaction, and (3) individual achievement in an entire class with no teacher interaction. The…

Failure to consider errors of measurement when using partial correlation or analysis of covariance techniques can result in erroneous conclusions. Certain aspects of this problem are discussed and particular attention is given to issues raised in a recent article by Brewar, Campbell, and Crano. (Author)

Procedures for grouping students into homogeneous subsets have long interested educational researchers. The research reported in this paper is an investigation of a set of objective grouping procedures based on multivariate analysis considerations. Four multivariate functions that might serve as criteria for adequate grouping are given and…

A statistical model designed to assist elementary school principals in the process of selection educational areas which should receive additional emphasis is presented. For each educational area, the model produces an index number which represents the expected "value" per dollar spent on an instructional program appropriate for strengthening that…

Some stochastic approximation procedures are considered in relation to the problem of choosing a sequence of test questions to accurately estimate a given examinee's standing on a psychological dimension. Illustrations are given evaluating certain procedures in a specific context. (Author/CK)

This paper investigates the influences of traditional kinds of verbal and quantitative achievement and aptitude variables on high school foreign language achievement, as measured by Modern Language Association and University of Washington tests of language skills administered to entering college students. The report focuses on: (1) the sample and…

The purpose of this study was to investigate a test procedure to determine auto mechanic know-how. Participants were allowed to look at, feel, and smell a number of defective vehicle parts in order to identify the part, indicate its condition, decide why it failed, and decide on whether to reuse it or not. The test was divided into 10 categories…

Some of the more significant responses to a questionnaire on educational and occupational aspirations and expectations which was administered to a statewide sample of sophomores, juniors, and seniors in 30 rural high schools by the Department of Rural Sociology at Washington State University were presented in this report.

The purpose of this study was to examine metropolitan-nonmetropolitan and sex differences in the role models selected by Negro high school sophomores. A questionnaire was grouped-administered to 111 metropolitan males, 170 metropolitan females, 98 nonmetropolitan males, and 99 nonmetropolitan females. The results of the study indicated that sex…

Statistical procedures are presented for determining ordinal and disordinal aptitude-treatment interactions with linear and curvilinear data. The paper presents a method for testing the homogeneity of group regressions for a single aptitude and provides models for expanding this test to linear and curvilinear regression planes. Procedures are…

This paper describes several situations in which generalization of statistical results is not possible by representative sampling but which is attempted using corrections for selection of groups. The situations include hiring, admissions, differential classification, guidance, test score equating, and test score scaling. Evidence of inaccuracies…

A methodology for busing to achieve school desegregation is described. Two different approaches are proposed: a student interracial contact score and a quota method. Travel time and number of children bused are proxies for busing costs. Useful data include travel time, school capacity, and student residences for each region and level of school. A…

The quality and utility of NCEC information analysis products, including ERIC clearinghouse products, PREP reports, and EMC bibliographies, are evaluated. The chapters in this volume of the evaluation study are as follows: I. Introduction, which describes the NCEC information analysis products, issues to be addressed, study approach, and report…

An investigation was made of the relationship of achievement marks assigned by teachers to elementary grade, lower socioeconomic status boys and girls to pupils' (1) racial background, (2) sex, (3) intelligence quotient, and (4) tested achievement. Teacher marking procedures were studied. The rationale was to inquire whether or not characteristics…

The purpose of this study was to quantitatively assess 17 secondary area vocational centers in Illinois. Data were intended for use in the decision-making process relative to new programs, and were not used as a means of comparing the efficiency or effectiveness of the centers studied. Factors included in the study were the length of operation,…
