A four-year longitudinal study of concept attainment and uses of concepts, as specified by the Conceptual Learning and Development Model, is described. Data collected during the first two years were based upon the assessment of the concept, equilateral triangle. The assessment battery was administered to 351 children (grades K, 3, 6, and 9) in…

In order to determine the cognitive development of Navajo children in terms of Piagetian conservation of number, mass, and continuous quantity, 168 Navajo children at seven different age levels from 5 to adult were presented with a series of three conservation tasks. The tasks consisted of a standard object and an equivalent object that could be…

In a test the presence or absence of a "structure" in the individual's cognitive processes of formal operations thinking, 61 fourth, fifth, and sixth grade students were administered three tasks supposedly requiring such a method of thinking. The three tasks were (1) a problem solving task (PS), (2) a chemistry task requiring a certain combination…

An experiment in teaching logic to fifth graders using a children's story is reported. Part one of the report develops the experiment's rationale. A lack of reasoning ability among children is perceived and several causes are suggested -- among them a reliance on reading, math, and science as vehicles for reasoning, emphasis on problem solving…

In order to investigate the hypothesis that the conceptualization of sequence precedes that of simultaneity in child development, and to explore the use of elicited imitation in studying lexical acquisition, 32 subjects between 3 and 5 years of age were asked to verbally imitate a list of sentences. The constructions combined simple and reverse…

This research studied the effects of abstract-reasoning ability, degree of bidialectism, and grade level on listening comprehension tasks presented in both Standard English and Black English and on oral reading and oral-reading comprehension tasks presented in Standard English, Black English standard orthography, and Black English nonstandard…

This educational research project is designed to assess an elementary student's quality of reasoning in relation to map skills and to determine spatial concept abilities. 21 activities are designed to test sense of proportion, scale, dimension, accurate relationship, and abstract thinking. The related topographical map, a Map-Study Scoring Key,…

Evaluation results are reported for the Southwest Educational Development Laboratory's Thinking and Reasoning Program, designed to develop analytic thinking and problem-solving skills in young children in multicultural classroom settings. Results are based on a pilot test of the program conducted during the 1974-75 school year. Mastery activities,…

This article presents 10 practical teaching procedures to encourage students to develop formal reasoning skills. A twelfth-grade English course is used as an example. Procedures include pretesting, sequencing instruction, providing students with concrete experiences, discussing reasoning patterns and forms of argumentation, assigning argumentative…

Analyzes the art criticism of nine university art education students writing about the work of Robert Rauschenberg. Identifies the students' use or nonuse of thematic unity, intertextuality, opposition, and description. These thinking strategies are primarily found in the works of three professional art critics. (MJP)

Examines operations of generalization, identification, discrimination, and synthesis in mathematical concept development from early childhood to late adolescence according to Vygotsky's theory of development. (MDH)

Developmental changes in self-perceptions were studied in children and adolescents in grades 4, 6, 8, 10, and 12. The responses of subjects to the question Who am I? were analyzed by means of a 30-category scoring system. Children described themselves in terms of their physical appearance and their behavior, while adolescents referred to their…

Describes a study which was designed to determine the effect of a 25-hour introductory qualitative analysis course on high school students' understanding of formal concepts related to electrolytes. Suggests that introductory concrete experiences better prepare students to deal with more formal abstract concepts. (TW)

Examines content and problem effects of formal thought in 13-year-olds (N=120). Three controlling variables tasks with different content and two question-type tests (analysis and controlling questions) were administered. Findings, among others, indicate that content and problem effects contribute to variance on formal reasoning problems.…

Defines a generalization as "a descriptive statement of broad application indicating a relationship between two or more concepts." Argues that successful teaching about generalizations can only occur when students understand the relationship between concepts and facts. Discusses four issues and four approaches related to teaching…
