The validity of a spatial visualization test for selecting candidate engineering students was assessed. The test was administered to 300 out of the 318 students enrolled during the winter quarter of 1989 in the Engineering Graphics 110 course at a major state university. Developmental steps undertaken to enhance the theoretical basis and validity…

This collection of abstracts is part of a continuing series providing information on recent doctoral dissertations. The 26 titles deal with a variety of topics, including the following: (1) individual differences in the use of comprehension strategies; (2) field dependence-independence and text comprehension; (3) automaticity of word…

This report describes the construction and testing of two "psychological" learning models for the purpose of computer recognition of human speech over the telephone. One of the two models was found to be superior in all tests. A regression analysis yielded a 92.3% recognition rate for 14 subjects ranging in age from 6 to 13 years. Tests…

The purpose of this study was to investigate the organization of associations among college-aged women's perceptions of individual and family-level separation-individuation difficulties and two subtypes of depressive vulnerability proposed by Blatt. One type is focused on achievement and issues of self-worth; the other type is focused on…

Described is a learning activity that requires students to observe, read, and interpret graphs and organize and describe data. Included are the grade level, materials, objectives, prerequisites, directions, answers to questions, and copies of handouts. (KR)

Described is a method for drawing periodic tile patterns using LOGO. Squares, triangles, hexagons, shape filling, and random tile laying are included. These activities incorporate problem solving, programing methods, and the geometry of angles and polygons. (KR)

This article describes a way in which the computer can be used by students in exploring patterns and solving problems associated with number theory. BASIC programs are described, along with classroom questions and procedures that aid in implementation. (Author/KR)

Discusses the use of computer visualization to motivate and support mathematical dialogues. Describes the "Scientific Visualization Software Suite," a set of public domain visualization tools from the National Center for Supercomputing Applications. (Author/MDH)

Perceptual units are involved in the reading process in a particular way. Reading starts with patterns of visual perception visual stimuli in combination with either previously learned information or a strategy for selectively attending to part of the stimuli. Whether the visual pattern selected for deeper information processing is a letter, a…

Aspects of problem-solving measured here are delay of gratification, field-dependence independence, and the relection-impulsivity dimension. The following hypotheses are proposed (1) Those subjects who score high on externality will not delay gratification as those who score low, but they will score lower on measures on field-independence than…

Research developments in cognitive psychology, and their implications for teaching and learning at the level of professional education, are summarized. Areas discussed include organization of long-term memory, influences on storage and retrieval from memory, problem solving and transfer/use of analogy, concept formation/categorization/pattern…

Discussed are ways in which students can generalize both quadratic or cubic situations. Generalizations are produced using the factor method, repeated linear generalizations, means of the mean, and through the use of differences. (KR)

Described are activities that use a hundred chart to improve student abilities to recognize and describe number patterns, to use variables, to make and informally prove conjectures, and to communicate mathematical ideas to classmates. Included are the directions, four reproducible student sheets, the answers, and extensions. (KR)

Presented is an activity that explores the relationship between the size of a rectangle and the number of squares intersected by a diagonal. Students incorporate pattern recognition and the concept of the greatest common divisor in solving the problem. A sample worksheet is provided. (MDH)

Electronic language corpora, and their attendant computer software, are proving increasingly influential in language teaching as sources of language descriptions and pedagogical materials. However, few teachers are clear about their nature or their relevance to language teaching. This paper defines corpora and their types, discusses their…
