Examined longitudinally were the rate and proportion by grade level of the cognitive development of 202 13- to 16-year-old educable mentally handicapped students. A 20-item written test composed of eight problem solving and 12 cognitive development items representing the concrete I, concrete II, and formal I operations levels of Piagetian theory,…

This paper discusses bilingualism from the point of view of language universals, including Fillmore's case grammar, McCawley's "anywhere rules" for lexical insertions and Slobin's operating principles in first language acquisition. It is assumed that first and second language learning is essentially the same, regardless of age. Whereas…

An attempt is made in the present paper to resolve inconsistencies between the results of recent studies which have reported that bilingualism is associated with positive cognitive consequences and earlier studies which suggested that bilingualism might adversely affect cognitive and scholastic progress. Because recent studies involved balanced…

Previous studies have reported that disadvantaged children tend to loose the skills and abilities they had acquired in special and/or intervention programs when they are placed in education settings which do not support their needs. Since the 1970 census data tended to indicate that the pupil composition of the schools had changed, it became…

This study tested certain implied predictions regarding conceptual learning at each of four sequential levels of development: concrete level, identity level, classificatory level, and formal level. For this purpose, scaled batteries to assess the level of conceptual development of children, kindergarten through high school, were constructed and a…

Cognitive effects in children's learning of altruistic behavior were tested with an adaptation of Aronfreed's test design and machine. Children in grades 1-4 were presented with a machine with 2 levers. One lever, when pressed, released bubble gum, and the other turned on a light. For two of the three groups the experimenter exclaimed delightedly…

Empirical longitudinal evidence is presented regarding the positive relationship between test scores and the amount of time students participate in preschool and kindergarten classes. This positive relationship exists independent of a wide range of teaching styles, materials, and methodologies. Findings are based on four years of observations with…

The perceptual-developmental research of Kagan and Witkin elicited this study of cognitive style. The work of these two researchers leads to the conclusion that differences between graphic expressions of children of the same age reflect differences in the children's mode of information processing. Specifically, this study sought to test the…

Analysis of 65 children over a 4-year period on tests of operational and causal thinking offers support for Piaget's notion of stage progression. In kindergarten and grade one, the majority of children in this longitudinal study were between preoperational and the achievement stage of operational thought. By grade two, the majority had attained…

The objective of this study was to develop and evaluate two procedures for providing preschool education for rural 4-year-olds by using a mobile laboratory. The project used "readimobiles" to determine the effectiveness of a structured, psycholinguistically-based preschool curriculum on black, disadvantaged children. There were three…

This manual evaluates and describes an educational day care model after 1 year of development. The model was designed for 3- and 5-year-old disadvantaged youngsters who exhibit low scores on intelligence, linguistic, and perceptual tests. Model objectives were based on the following criteria: (1) effectiveness of the curriculum with children, (2)…

Fifteen bilingual and 15 monolingual Head Start children, ranging in age from 4 to 6, were administered three types of tasks: (1) object constancy task: subject was shown a common object, a transformation was done on the object, e.g., crushing a paper cup, and then that object plus an identical pre-transformed object, were shown to the subject and…

Changing educational practices require changes in our theories and techniques of evaluation. Three forces of change are: (1) The emphasis on cognitive development in the disciplines; (2) the continuity of education over the span of life; and (3) the adaptation of instruction to individual requirements. These influences dictate a form to which…

Noting the need for action to alleviate the illitaracy which handicaps half of the world's population and 11 percent of America's, it was emphasized (1) that the problem is particularly intense in urban schools where failure rates and nonreaders run from two-thirds to 50 times higher than in other schools; (2) that the percentage of retarded…

Five factors should be considered in understanding the value of children's literature in the elementary school curriculum, as both an aesthetic and utilitarian experience. Children's literature is significant (1) as an information supplement in science, art, social studies, mathematics, and other curriculum subjects; (2) as a vital part of the…
