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…

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 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…

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…

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…

THE EFFECTIVENESS OF AN INTEREST-MOTIVATED METHOD OF INSTRUCTION IN REMEDIAL ENGLISH WAS EVALUATED. ALL STUDENTS INVOLVED IN THE PROJECT WERE PERSONS WHO HAD GRADUATED FROM HIGH SCHOOLS IN THE LOWER 40 PERCENT OF THEIR CLASSES. THEY WERE ADMITTED TO COLLEGE ON A PROBATIONARY BASIS. EIGHT GROUPS OF STUDENTS WERE INVOLVED. FOUR GROUPS WERE…

Discusses the problems that arise in test situations when some, but not all, students use electronic calculators and poses some solutions to these problems. (MLH)

Alabama's laboratory certification program ensures that water quality control and testing methods are in compliance with the Safe Water Drinking Act. (BB)

Answer changes on tests are more likely to be made on items early in a group of questions, toward the end of a test, and on difficult items. The reasons for this student behavior are examined. (Editor/JD)

Teachers can determine the content validity of standardized tests before using them. Two tests are compared to illustrate the process. (MP)

The Hand Test, a projective device involving drawings of hands in semi-ambiguous poses, has increased in popularity among clinical and school psychologists in the 15 years since its inception. Research on the test is reviewed and its merit in clinical and diverse assessment situations is discussed. (Author/JAC)

Describes the method and the options, provided with the use of the computer for scoring and analyzing tests. (GA)

The present investigation was conducted to determine if stimulus overselectivity in 19 autistic children (5 to 12 years old) is changed as a function of repeated exposure to testing. (Author/SBH)
