This article examines students' ability to use the balance model to solve for unknowns. A teaching experiment was conducted in four Year 3 classrooms. This experiment focused on exploring the application of the balance model as an analogue for representing equations and solving for unknowns. The teaching experiment promoted a shift by students…

The authors describe one high school teacher's attempt to change her mathematics teaching in ways that are consistent with the National Council of Teachers of Mathematics'"Standards" documents. One of the coauthors is the teacher who teaches in a professional development school; the other, a researcher, conducted regular observations in…

The "componential" theory of intelligence explains intelligence in terms of three types of component processes that make up intelligent performance. The first of these, "metacomponents," are the higher-order or executive processes that one uses to plan what one is going to do, monitor what one is doing, and evaluate what one…

College attendance patterns, areas of study, and abilities of Asian Americans are considered. Asian Americans pursue higher education at somewhat higher rates than average, and the rate is increasing. They concentrate in business, the physical sciences, and engineering in greater than expected numbers in comparison with the general student…

A study investigated the reason for the high performance of bilingual children on a syllogistic reasoning task. Thirty-nine Puerto Rican Spanish-English bilingual children in grades 3 through 6 were asked to solve problems in both languages. Response times were recorded, and the subjects were asked to justify their answers to assess to what extent…

This paper attempts to fill some of the gaps in the literature (on reflective teaching), delving further into the meaning and functions of reflection. First, it considers the origins of the term and some aspects of its development. It then analyzes and critiques some of the current notions of reflection. Beginning the process of a more rigorous…

A model for the development of scientific reasoning in adolescents was formulated largely upon the basis of Piagetian theory. Included as potential determinants of scientific reasoning were: experience; age; locus of control; field dependence-independence (FID); rigidity/flexibility; intelligence quotient (IQ); and sex. Causal relationships…

This 10-day study compared the effects of alternative ways of using microcomputer simulations on the achievement and attitudes of sixth- and seventh-grade science students (N=173). Nine classes were randomly assigned to one of four treatments: (1) microcomputer simulations; (2) laboratory activities; (3) a combination of simulation and laboratory…

In the first section a sketch of a tense logic is presented and a mechanism is suggested for including aspects of the tense logic into the Grammar (theory of language). Specifically, several grammatical structures are shown to incorporate temporal features. A semantic projection mechanism is utilized to amalgamate the temporal features in elements…

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…

The purpose of this pilot study was to provide data from which tentative conclusions could be made about adults and their ability to handle literary abstractions. A sample of 93 inmates (all male, 26 Negro, 67 white) at Sumter Correctional Institution was randomly chosen and asked to verbalize their reactions to four comic strips and to write…

Curriculum guides for four social studies instruction modules at the secondary level are included in this document. The general format for each twelve week course includes a diagram of concept relationships, prefatory remarks, and an outline of concepts coordinated with activities and instructional resources. The first module, Geographic Patterns,…

Performance in concrete and abstract tasks is examined systematically by varying the degree of abstractness of problem-solving and concept formation tasks. Four forms of a problem solving test were constructed. Each form of the test presented problem situations through four different modes: verbal stories, picture-book, color slides,…

Designed for a social studies program stressing the inquiry method, this packet of sample test questions uses a thematic rather that a topical approach. The four thematic categories are geography, religion and philosophy, cultural characteristics and relationships, and socialization. Four levels of the thinking process are identified and questions…

The major results and conclusions of a program of research concerned primarily with the relationship of cognitive abilities to learning are summarized. The major purpose of this research was to develop theorems of instruction related to the interaction of task variables and individual difference variables and to develop them in a manner relevant…
