This collection of research papers considers extensions of the Rasch model. In Chapter 1, K. C. Cheung explains how measurement and testing in the classroom can be made more meaningful, particularly through the use of Rasch family item response models. In Chapter 2, K. W. Koon and K. C. Cheung apply the Rasch model in constructing a part-whole…

The purpose of this study was to investgate the role of self-efficacy expectations in understanding gender differences in the election of college computer science courses. Participants were 368 undergraduate students (males=104, females=264) enrolled in a course fulfilling a general education requirement at a large urban university. A two-page…

This publication is the third in a series of biennial reports in which academic resources in science and engineering are analyzed. It is based primarily on findings from four National Science Foundation surveys that collect information on academic research and development (R&D) expenditures, federal obligations, employment of scientists and…

Six studies discussed in this paper compared error-specific or model-based remediation (MBR) with reteaching in algebra. MBR points out, and highlights as incorrect, errors specific to the student's solution before reteaching the correct procedures. Reteaching shows the student the correct procedure without addressing specific errors. Three of…

This paper provides an overview of the four major aspects of the PIXIE Intelligent Tutoring System: the field work undertaken to determine how teachers diagnose and remediate in introductory algebra; the set of experiments run to determine the relative effectiveness of Model-Based-Remediation (MBR) and Reteaching; systems work carried out to…

These proceedings include four papers that examine four different models of the engineering labor market, namely, those of: (1) the American Electronics Association ("Technical Employment Projections, 1983-1987" by Pat Hill Hubbard); (2) the Bureau of Labor Statistics ("Future Labor-Market Conditions for Engineers" by Ronald E.…

Developed from presentations given at a 3-day invitational meeting of 31 leading online catalog designers from both public and private sectors in North America, these papers provide information about online catalogs--their present form, their use, and the questions that need to be considered in their future refinement. All of the papers in this…

It is pointed out that there is a desperate need for engineering and computer science doctoral faculty, a need recognized by various schools of science and engineering and by the Federal government. Although the National Science Foundation and other agencies do not see a shortage of college faculty in the other sciences, faculty in some of these…

This report is the 30th in a series that covers research and development (R&D) as shown in successive Presidential budgets. The Federal budget for 1982 was unusual in the extent to which it was subjected to change, reflecting the new administration's philosophy to reduce Federal spending. R&D funding data reflect the first series of 1981…

This publication is a source book of detailed statistical information on science and engineering (S/E) degree production for the period 1950-1980. Data used in the report cover earned degrees in the aggregate United States, which includes the 50 states, District of Columbia, and its outlying areas (American Samoa, Canal Zone, Guam, Northern…

Part I of this report consists of the American Association for the Advancement of Science overview of research and development (R&D) in the fiscal year (FY) 1985 budget and its associated policy issues, together with special analyses of several important topics, such as funding for basic research. A set of overview tables is included. Part II…

Interest in the Planning, Programming, Budgeting System (PPBS) has waned over the last five years for several reasons. Early rhetoric about PPBS obscured its true character and promised more than it could deliver. Initially, few had the competencies needed to implement it. It is often wrongly believed to be solely a budgeting system. Finally,…

The purpose of this document is to increase the educator's awareness of the present situation in computers in the school. Although the study was directed at computers in the secondary mathematics curriculum, of necessity much of the material dealt with broader aspects of the computer in all secondary curricula. The first section of this report…

The report describes a large-scale computerized system for Selective Dissemination of Information (SDI) developed over the past five years at the U.S. Army Electronics Command to serve its technical personnel. The system, which uses as its document base the current accessions of the Defense Documentation Center, was developed in three phases: (1)…

The Central Atlantic Regional Educational Laboratory (CAREL) Center for Educational Diagnosis and Learning is a model based on a cybernetic approach for the development of educational programs designed to personalize the student's instructional experiences and humanize his daily living. The CAREL Project has set three major objectives and 12…
