The issue of multiple-choice (MC) vs. created-response (CR) test-item formats was reexamined at the eighth-grade level in three subject areas: general science, American history, and arithmetic. In each subject area, alternate forms with the same item-content but differing in which items were in which format were prepared from standardized tests.…

Similarities among ethnolinguistic groups are greater than differences. It is the belief in the influence of culture and language on basic structures of thought and personality that divides groups, not the structures themselves. However, linguistic differences among ethnic groups are real. The linguistic distinctiveness of a particular ethnic…

This paper offers a preliminary analysis of the effects of a semi-segregated school system on the IQ's of its students. The basic data consist of IQ scores for fourth, sixth, and eighth grades and associated environmental data obtained from their school records. A statistical model is developed to analyze longitudinal data when both process error…

This project was designed to explore the relationship between school achievement and birth weight in a population of poverty black school children in the hope that the assumptions about environmental similarity might be approximated, and that the relatively advanced age of the subjects would allow examination of the lasting effects of birth…

This study examines the relationships between reading comprehension and listening comprehension among second graders with regard to age, reading ability, and intelligence. One form of the Gates-MacGinitie Reading Test was administered to 66 second graders to measure reading comprehension and a revised alternate form of the same test measured…

The study examined: (1) the effects of rural-urban background and social class on scholastic performance in college, and (2) the rural-urban differences in scholastic performance when controlled for social class, sex, and measured intelligence. Data originally collected by students' self-reports and administrative records for panel-designed…

Forty-eight special class educable mentally retarded (EMR) students, 9 to 12 years of age, from lower socioeconomic backgrounds were examined to determine effects of communication training and learning potential (LP) training on tasks in the Communication Test Battery (CTB) and on scores in the Raven Progressive Matrices (RPM). The Ss were…

An entire elementary school system with 60 percent white and 40 percent black children was given several ability tests administered by 12 white and eight black examiners. The tests measured verbal and nonverbal IQ, perceptual-motor cognitive development, "speed and persistence" under neutral and motivating instructions, listening attention, and…

The purpose of this study was to determine if selected mental, mathematical, reading, and personality assessments of sixth-grade pupils could predict high achievers in mathematical verbal problem solving. The subjects were 112 sixth graders, 56 classified as high achievers in mathematical verbal problem solving and 56 classified as low achievers…

The study was based on a year's work with Crow Indian children, grades 1-4, at Pryor, Montana. Five tests were given and evaluated: the Stanford-Binet Intelligence Scale, the Metropolitan Achievement Tests, the Gesell Developmental Examination, the Lowenfeld Mosaic, and 3 selected tasks from Piaget. The 21 pupils used for this study were broken…

This study was undertaken to investigate approaches fifth grade children of similar mental ability follow when writing narrative compositions, to identify procedures unique to good and poor writers, and to observe sex differences relative to quality of written expression and ability to verbalize concerning the writing process. A sample of 230…

An investigation was made to determine (1) if different reading comprehension subtests measure the same facets of comprehension, (2) what proportion of variance is accounted for in scores if verbal comprehension is partialed out, and (3) how highly group intelligence test scores correlate with comprehension tests which require immediate recall and…

ARIS is an artificial intelligence system which uses the English language to learn, understand, and communicate. The system attempts to simulate the psychoneurological processes which enable man to communicate verbally. It uses a modified stratificational grammar model and is being programed in PL/1 (a programing language) for an IBM 360/67…

SCHOLAR is a computer-assisted instruction (CAI) system which is capable of true man-computer dialog. Using a subset of English, the system is capable of generating questions, answering questions, analyzing responses, and producing subsequent actions. SCHOLAR has a data base that is a complex but well defined information structure in the form of a…

A relational data system (RDS) is one that has the capability not only to retrieve specific facts but also the ability to deduce facts that are implicit rather than explicit in the data base. The study investigated the application of RDS technology to intelligence data processing. RDS technology and the nature of intelligence data processing are…
