This study was built on the hypothesis that linguistic cues distinguish the speech of the poor and the ethnically different. Eight samples of connected interview discourse were taken from a two-by-two-by-two matrix of sex, race and social status. The samples were played to groups of elementary, secondary and college students who rated each voice…

This study sought to test the interpretation that high test anxiety subjects performed more poorly on difficult material because they divided their attention between personally relevant and task relevant concerns to a greater degree than did low anxiety individuals. It was reasoned that such division of attention ought to require more time for…

The purpose of this study was to arrive at a criterion for grade prediction for college freshmen enrolling in a non-laboratory biological science course. The independent variables employed (selected on the basis of availability from previous academic performance) were: (1) high school overall grade point average (GPA), (2) high school science…

The sign test is perhaps the simplest nonparametric procedure comparable to the commonly used parametric t-test. This test is easily applied which makes it useful preliminary analysis and for the analysis of data of passing interest. A large variety of its applications to education research, usually not found in the standard textbooks, is included…

The major thrust of this issue of "Impact" is "New Therapies." Dr. William Glasser comments on his "reality therapy" and Robert Carkhuff discusses his "systematic eclectic approach to helping." This issue also contains articles about an indictment of the Strong Vocational Interest Blank in regard to women. Other departments contain ideas,…

Two experiments investigated the acquisition of course material under conditions of repeated testing. In Experiment I, with limited study intervals, acquisition increased over trials of study followed by testing. In addition, adjunct information about the content of the test item pool also increased performance. In Experiment II, with student…

Sixteen kindergarten and 28 first-grade children were tested on two-choice discrimination problems. A prompt light indicated the positive (rewarded) object P on all training trials, and these were followed by a single nonprompted test trial during which a new object (X) replaced either P (X-N problems) or N (P-X problems) or neither (P-N control…

Test development efforts for constructing 35 of the tests included in a battery of 56 tests of possible cognitive abilities are described. Data were collected on 172 boys and 210 girls who had just completed the fifth grade. Item and total score statistics obtained for the 56 tests in the total battery are presented and discussed.

The area investigated in the present study is the comparison of the permutation t-test with Student's t-test and the Mann-Whitney U-test. The comparison was made for small samples for three distributions, including a normal distribution, a uniform distribution, and a skewed distribution. The properties of each test compared were the probability of…

The purpose of the simulated maintenance task environment is to provide a means for training and job performance testing of the flight line weapon control systems mechanic/technician for the F-111A aircraft. It provides practice in flight line equipment checkout, troubleshooting, and removal and replacement of line replaceable units in the…

One approach to the problem of analyzing classroom interaction by use of a Markoff chain is presented. The two sections of the paper present (1) a discusion of Hoel's test of order of a Markoff chain, and a Likelihood Ratio Criterion (LRC) for a two-dependent Markoff chain is given, and (2) a discussion of possible adjustments of Darwin's LRC with…

A description is given of a general method for studying partitions. The main focus is with the analysis of relationships among several different partitions of the same items for the explorations as well as confirmation of structural relationships. A partition is defined as a set of mutually exclusive clusters of items; however, this paper deals…

This is a methodological study that suggests a taxometric technique for objective classification of yeasts. It makes use of the minres method of factor analysis and groups strains of yeast according to their factor profiles. The similarities are judged in the higher-dimensional space determined by the factor analysis, but otherwise rely on the…

Recommendations of an Ad Hoc Advisory Committee relating to standardized testing in a state educational system are presented. The paper first discusses the concepts of measurement, evaluation, and standardized testing. Then follows discussions of Test Development, Qualifications of Test Users, General Use of Tests, The Use of Standardized Tests…

The primary purpose of this study was to evaluate the effectiveness of the university level multi-disciplinary course in the environment on bringing about heightened awareness of environmental events as reported in the mass media. A second, related study sought to determine whether particular values characteristically associated with the various…
