The main purpose of the research reported in this document was to discover whether controlled experiments can be conducted on the relations between people and the complex computing systems which they use. Three increasingly complex experiments were designed to test the effect of varying delays of computer response on the number of commands issues…

These proceedings include four articles intended to familiarize librarians with many facets of operations research and how they might be applied to their institutions. The first paper provides a brief definition of operations research. The second presentation, by Ralph Shoffner, relates, in the form of concrete examples, the questions one asks…

Presents several ways that the microcomputer can be used as an aid in teaching various topics in calculus, including graphing functions, solving equations, finding limits and derivatives, and solving optimization problems. Emphasizes the use of computer software that tends to maximize the potential of computer graphics in mathematics instruction.…

Presents reviews of five computer packages: (1) "Algebra Attack" contains games and tests; (2) "Bootstrap Stats" requires learners to write programs while studying probability and statistics; (3) "Geometry and Microcomputers" contains 13 lessons on mathematics and graphics; (4) "Math Grapher" is an algebraic…

The Indian Health Service (IHS), an agency within the U.S. Department of Health and Human Services, is responsible for providing health services to American Indians and Alaska Natives living on or near federal reservations (about 60 percent of the Native population). This publication is composed primarily of data tables and graphs that describe…

Presents an activity through which students develop mathematical concepts connected to area and perimeter in a rich, real-life setting and use tables, graphs, diagrams, and spreadsheets to explore the problem, see relationships, and make and test conjectures about those relationships. Encourages algebraic thinking. (SYB)

Discussed is the process of translating situations involving changing quantities into mathematical relationships. This process, called dynamical modeling, allows students to learn new mathematics while sharpening their algebraic skills. A description of dynamical systems, problem-solving methods, a graphical analysis, and available classroom…

Describes a study of library and information science faculty done to determine the need for replacements resulting from retirements and other withdrawals. The prediction of a serious depletion of faculty resources in library schools before 2001 is based on information gathered on age, gender, experience, and retirement plans. (14 references) (EAM)

Reports the findings of a study of library and information science faculty and compares results to a previous study of social science and humanities scholars. Topics addressed include collegial research relationships, publishing, professional association activities, attitudes toward scholarly and professional literature, computer skills and uses…

The growing body of research investigating how people search for or locate information in a variety of materials is reviewed and extended. Although the nature of materials and the complexity of locating tasks varies in the seven articles, each aims to elucidate the conditions that affect search processes. (SLD)

Effectiveness in presenting information of a modified box plot and a multivariate STAR graph was compared with that of tables for a sample audience for evaluation results (133 school superintendents, 123 journalists, 100 school board members, 100 principals, 100 teachers). Individual item analysis offers guidance for designing multivariate…

Presents the case against private school choice, exploring myths and facts about public and private education. Private school choice would not increase accountability and would not bring about healthy competition for students. In addition, private schools do not outperform public schools to the extent one would expect. (SLD)

Describes an instructional unit using graphic organizers to teach about federalism in a U.S. government course. Includes models of charts and lists of appropriate student responses. (CFR)

Presents a project in which students monitor their use of trash, input and analyze information via a database and computerized graphs, and "reconstruct" extinct or endangered animals from recyclable materials. The activity was done with second-grade students over a period of three to four weeks. (PR)

This paper presents Petri net software tool P3 that is developed for training purposes of the Architecture and organization of computers (AOC) course. The P3 has the following features: graphical modeling interface, interactive simulation by single and parallel (with previous conflict resolution) transition firing, two well-known Petri net…
