The effectiveness of audiotutorial and teacher-directed inquiry in promoting school achievement was explored. High school biology students from two dissimilar populations were administered ten Piagetian-styled tasks to determine the student's operational level. Analysis of data on operational level and age determined that inner-city students…

This study examined the relationships between cognitive development, language acquisition, and socioeconomic class, as manifested in children's written language. Four classes of sixth-grade students participated in the investigation, a control class and an experimental class from each of two socioeconomic environments (low and high). The treatment…

The study compared the level of development observed in the imaginative play of young children with the level of development revealed in conservation an classification tasks. The sample included 40 children, with one 5/6-year old group of 20 children (10 boys, 10 girls), and two six/seven-year old groups of 20 children (14 boys, 6 girls). The…

It was hypothesized that children, like adults, cognize social groups by applying social schemata. Their facility with social schemata was predicted to be a function of their level of cognitive development. When children were asked to complete partial social structures, formal and concrete operational, but not preoperational children, readily…

The conference papers in this collection emphasize the theoretical significance of their authors' work in the areas of mathematical and cognitive psychology. Major topics considered include facilitation of problem solving; psychological differences among problem isomorphs; the process of understanding in problem solving; processing information for…

Developing learning-teaching procedures is only possible if one knows the internal processes to be formed. Two 'psycho-logical' models and activity algorithms for foreign language teaching are discussed. Construction of such operational models for grammatical action has a high diagnostic value for research and development in FL teaching. See FL…

In one experiment, children from 5 to 10 years of age played with puppets and responded to questions concerning the acquisition of one particular linguistic structure by children; in another series of experiments, both children and adults responded to questions regarding nonsense words in differentiating contexts--the focus of the discussion…

Research findings related to the development of language, abstract reasoning, and problem solving-skills by children from three to eight years old are integrated by consideration of classroom implications. Individual differences, the teacher-child relationship, and other topics are also discussed in this context. (SD)

After a discussion on planning instruction, a series of activities designed to develop pre-number and number concepts are presented. Activities are arranged by difficulty within sections devoted to classifying, comparing, ordering, measuring, organizing data, distinguishing shape and size, recognizing patterns, number awareness, and counting.

This study examined the factors influencing the choice of the conjunctions "and" or "but" in joining two clauses of a compound sentence. Subjects were students at first-, fourth-, seventh-, and tenth-grade and adult levels. (Author/ED)

Examines themes evident in children's and mother's definitions of illness to determine how views of illness develop. Subjects were 264 children (ages 6 to 12-11) and their mothers. Two issues were considered: (a) patterned similarity in illness definitions, and (b) developmental changes in illness concepts. (ED)

Children in grades 1, 3, and 5 and college students were given a variety of judgment tasks contrasting the comparison of quantity with the comparison of proportions to determine whether the understanding of proportions develops before formal operations. Results indicated that the comprehension of abstract relations requires formal operations.…

Experiments by Russian educators on teaching algebra in elementary grades are summarized by the author. The algebra taught consisted of generalized solutions to concrete problems that are usually presented with fixed numerical values. (JP)

Cites research indicating competence is necessary condition of mental health. Defines cognitive competence as crucial form of mastery, attempts to show how it develops and illustrates how mental health depends on this capacity. Sketches out four conditions which psychological education curriculums can provide for facilitating students' acquisition…
