This study examined cognitive processes and outcomes associated with student knowledge base development. Sixty-nine students from two grade 8 classes were randomly assigned to one of three groups: a knowledge base development (KBD) group, a problem-solving software group, and a control group. Those in the KBD group received relevant instruction…

This evaluation of the 1988-89 Instrumental Enrichment (IE) program in selected special education classrooms in Detroit (Michigan) found that the program was partially successful in achieving its goals. IE uses a series of paper-and-pencil exercises and follow-up discussions to increase participants' academic achievement, improve behavior, and…

As human understanding is largely metaphorical, what metaphor is, how children use it, and how they can be taught to use it more effectively are important educational concerns. A direct or indirect comparison between two apparently unlike things, metaphor consists of a topic, a vehicle of comparison, and ground--or traits--linking the topic and…

Using techniques of inference appraisal suggested by T. A. van Dijk and R. J. Sternberg, a study investigated whether by assigning particular writing tasks it would be possible to influence the way readers produce inferences about a text. Subjects, 52 ninth grade students, read especially prepared booklets and completed either a paraphrasing,…

After presenting a research review indicating that English as a second language (ESL) secondary school students need to improve their thinking skills, this paper reports on a study in which 136 analogies were developed for use as tools to teach these students to read at inferential and applied levels. The vocabulary source for the analogies was…

This paper summarizes a report designed to provide the National Science Board Commission with information about recent advances in cognitive/behavioral science relevant to mathematics, science, and technology education, as well as prospective contributions from these fields if adequate levels of support are available. Following a summary…

As part of an investigation of the effectiveness of a microcomputer-based laboratory (MBL) activity in developing students' graphing skills, this study was specifically designed to examine the differences between females and males in both performance on graphing tasks and on their attitudes to graphs and graph-based activities. Results based on a…

A 3-year study was conducted to determine the logical reasoning processes necessary to construct line graphs. Responses obtained from middle and high school science and mathematics students were classified into one of nine categories. These categories ranged from "no attempt to make a graph" to "complete graph with a statement of a…

Initially differentiating ideas of self-concept, personality, and self-esteem, this paper discusses the development of the self from infancy through adolescence. The discussion of infancy focuses on learning about bodily self and related disruptions and describes the emergence of the social and independent self. The discussion of toddlers and…

Students' abstract reasoning abilities can differ from one society to another. Students' profiles play significant roles in these differences. The aim of the study is to determine the relationship between middle school students' cognitive development levels and their profiles (age, gender, and science achievement) using the Science Cognitive…

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…

THIS STUDY INVESTIGATES THE EFFECT OF A TEACHER'S BELIEF OR CONCEPTUAL SYSTEM ON HIS TEACHING METHOD AND ON THE CLASSROOM ATMOSPHERE CREATED BY THAT TEACHING METHOD. A BELIEF SYSTEM WAS CHARACTERIZED AS EITHER CONCRETE OR ABSTRACT. A CONCRETE SYSTEM WAS REPRESENTED BY A TENDENCY FOR THE TEACHER'S INSTRUCTIONAL APPROACH TO BE MORE STRUCTURED, MORE…

An experiment was conducted on the effects of two teacher variables and student engagement on science achievement. The variables included: teacher wait-time, defined as the length of the pause preceding a teacher utterance; and questioning quality, a generic term used to describe cognitive level, clarity, and relevance of questioning. Thirteen…

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…

Two types of items used in student evaluations of college teaching were compared: high-inference items, which require considerable inferring from what is seen or heard in the classroom to labelling of teacher behavior; and moderate-inference items, such as "teacher listens carefully." Two instruments were administered to random halves of…
