A factor analytic study was designed to examine the factor structure of a battery of 17 tests administered to 100 students at the primary, intermediate, and advanced (grades 7-10) levels and to determine differences in factor structures for the three groups. The tests, measures of academic achievement, included the Wechsler Intelligence Scale for…

The following articles are included: (1) "Neurolinguistic Considerations on the Optimum Age for Second Language Learning" by Terence M. Walsh and Karl C. Diller; (2) "Major Variation in Language Skills Apparently under Genetic Influence (Discussed from the Viewpoint of Human Evolution)" by Brenda K. Sladen; (3) "Language Learning Strategies: Does…

The Graduate Record Examinations (GRE) bibliography provides an exhaustive list of references to studies adding to the understanding of the development, nature, and use of the test, and is divided into two sections: (1) the first section lists 125 annotated citations that contain research studies on the GRE; (2) the second section lists reviews…

OCCUPATIONAL NORMS IN TERMS OF MINIMUM QUALIFYING SCORES FOR THE APTITUDE MEASURES WHICH PREDICT JOB PERFORMANCE WERE ESTABLISHED. THE GENERAL APTITUDE TEST BATTERY AND TWO CRITERION MEASURES OF SUPERVISORY RATINGS WERE TESTED ON TWO SAMPLES, ONE CONSISTING OF 34 MALE AND 56 FEMALE CAMP COUNSELORS EMPLOYED IN NEW YORK STATE SUMMER CAMPS IN 1965,…

THE PRINCIPAL OBJECTIVES OF THIS STUDY WERE (1) TO DESCRIBE DEVELOPMENT STAGES OF STUDENTS FROM FIRST- THROUGH NINTH-GRADE LEVELS AS THEY AFFECT THE SOLUTION OF A THREE-DIMENSIONAL CLASSIFICATION PROBLEM, (2) TO UTILIZE THE INHELDER-PIAGET AND THE BRUNNER SYSTEMS OF DESCRIBING STAGES OF COGNITIVE DEVELOPMENT, AND (3) TO DETERMINE BY MULTIVARIATE…

Data were collected from the Air Training Command personnel processing files on non-prior-service accessions for male and female basic trainees entering the Air Force during the years 1970 through 1973. Data included age, Airman Qualifying Examination (AQE) aptitude indexes, years of education, race, and geographic area of enlistment. Tables show…

An Air Force systems-oriented electronics maintenance course for weapon control was developed and evaluated. A behavioral description based upon a task analysis of actual job requirements was first prepared. Based on objectives derived from these behavioral descriptions an experimental 14-week training course was developed. A group of subjects…

Since at least 1897, educational researchers have reported, with great frequency, "no significant differences" with respect to studies investigating the effects on educational outcomes of various treatments, suggesting that many educational variables are relatively impotent. A possible reason for at least many of the no-difference findings may lie…

Ways in which to determine whether the aptitude, intelligence, or achievement test is more helpful are discussed. A test's function, i.e., how the test results are used, appears to be the most logical method of discriminating between the types of tests. In educational testing, if the purpose is to evaluate the effectiveness of teaching or…

To develop General Aptitude Test Battery (GATB) norms for the occupation of photograph finisher, 59 female workers employed as photograph finishers in Wisconsin were administered all 12 tests of the GATB and the Research Questionnaire-Background during July 1969. Supervisory ratings of job proficiency were made at approximately the same time as…

Effects of item difficulty sequencing on performance and on post state anxiety were investigated using a timed mathematics aptitude test. The subjects were randomly assigned to a random, easy-to-hard, or hard-to-easy difficulty sequence group. The hard-to-easy sequence group performance was significantly lower than either the random or…

The impact of aptitude differences on learning performance is assessed. As a result of the assessment, instructional strategies are being developed to make efficient training programs for men of differing aptitude levels. Observations were that the high level group did better when left without a structured training program. The middle range was…

THIS STUDY TESTED THE HYPOTHESES THAT ONE SCHOOL IN A COLLEGE MAY BE EASIER THAN OTHERS IN THE SAME INSTITUTION, AND THAT STUDENTS IN ACADEMIC DIFFICULTY IN OTHER SCHOOLS WILL TRANSFER TO THE EASIER SCHOOL IN ORDER TO GRADUATE. THE STUDY WAS CONCERNED PRIMARILY WITH A LARGE SOUTHEASTERN COLLEGE WITH 12 SCHOOLS. DATA INCLUDED COLLEGE BOARD…

Examines the vocational aptitude patterns of males and females and Blacks and Whites. Work samples from the Micro-TOWER System of Vocational Evaluation were used to assess verbal, numerical, clerical perception, motor, and spatial aptitudes. Many differences were revealed of which counselors should be aware. (Author)

A factor analysis was performed on a set of variables (including subject characteristics, standardized tests, ratings, and work samples) used to predict work performance, or industrial rate, for 127 mentally retarded adults. (Author)
