This study determined the effects of two data collection techniques on response rate, response bias, response validity and respondent evaluation. Administration of a computer survey was compared to a machine readable paper survey. Cover letters were sent to 249 college sophomores who were randomly selected and proportionally stratified by intended…

This document includes 46 papers presented at the International Visual Literacy Association Conference on topics ranging from prehistoric cave paintings to technology of the future. Major sections are devoted to research and theory, education, computer technology, and phototherapy. Emphasis is on increased understanding of opportunities available…

Research has shown that wait-time (the amount of silence between teacher and student echances) is a part of an interdependent student-teacher interaction system and that the manipulation of this variable has measurable effects on teacher input variables, student outcome variables, and acquisition variables. Since the acquisition of extended…

This study investigated several aspects of a teaching experiment which focused on five seventh grade students' performance on nonroutine number theory problem-solving with a close look at the role of heuristics, concrete models, and the relationships between these variables. In the experiment, students were given a series of lessons on number…

Presents a detailed discussion of the data collected on calculator and computer use in schools in 20 countries. The document includes discussion of: (1) school policy on calculator use; (2) description of populations A (8th grade students) and B (12th grade students) in the United States; (3) uses of calculators in subjects other than mathematics;…

Mathematics curricula in Canadian schools, especially at the secondary level, have until now derived much of their content and ways of teaching largely from university mathematics and mathematicians. This feasibility study represents a first step in collecting and analyzing data from hi-tech industries, businesses and organizations. In Phase I, a…

The effects of using a microcomputer for electronic research on the achievement and attitudes of eighth-grade boys and girls (N=247) were investigated. The study analyzed three dimensions of student themes, two sets of computer achievement measures, and three attitudinal dimensions for each of three treatment groups. Results showed no unpredicted…

Discusses contributions that computers and computer networks are making to the field of medicine. Emphasizes the computer's speed in storing and retrieving data. Suggests that doctors may soon be able to use computers to advise on diagnosis and treatment. (TW)

Investigates whether elementary school students can construct operations of thought for integers and integer addition crucial for understanding elementary algebra. Two sixth graders were taught using a computer. Results included both students being able to construct mental operations for negating arbitrary integers and determining sign and…

This study compares the expectations of educators, parents, and business leaders regarding computer uses in education with their conceptions of what is actually being done. Respondents saw microcomputer use for recordkeeping, determining instructional needs, and instruction as important potential uses but felt that more should be done. (MBR)

Described is an article that describes an adaptive computer tutor for arithmetic entitled "Shopping on Mars." The purpose of the tutor is to help children develop an extensive repertoire of information techniques for performing arithmetic in everyday situations and to learn to formulate shortcuts in problem solving. Results of…

Designed to improve the long-term operational efficiency of the Montgomery County, Maryland, Public Schools (MCPS) payroll system, this study begins with an executive summary, including a set of recommendations and a chapter-by-chapter synopsis. Following an introduction to the study and a general description of the payroll system in chapters 1…

Adjunct questions were inserted after each of 12 computer-animated graphics sequences shown to 160 eighth-grade science students. These sequences presented two relationships in a purely spatial fashion. Four randomly assigned treatment groups received questions targeting one of the two relationships (temperature or molecular motion) over all or…

This paper discusses skills science teachers need to effectively use computing in their teaching and describes how pre- and in-service science teachers can acquire computing skills. These skills can be grouped under three headings: (1) computer as a tutor for students (such as using drill and tutorial programs to bolster achievement); (2) computer…

Discusses some of the contributions that high-speed computing is making to the study of science. Emphasizes the use of computers in exploring complicated systems without the simplification required in traditional methods of observation and experimentation. Provides examples of computer assisted investigations in astronomy and physics. (TW)
