Two sampling designs were compared for the planned 1978 national longitudinal survey of high school seniors with respect to statistical efficiency and cost. The 1972 survey used a stratified two-stage sample of high schools and seniors within schools. In order to minimize interviewer travel costs, an alternate sampling design was proposed,…

An experimental solar heating system heats five modular classrooms at the Fauquier County High School in Warrenton, Virginia. The present report covers the operation, maintenance, and modifications to the system over the 1974-75 and 1975-76 heating seasons. The solar system has shown the capability of providing essentially 100 percent of the…

This report covers a two-year and seven-month solar space heating and cooling experiment conducted at the Timonium Elementary School, Timonium, Maryland. The system was designed to provide a minimum of 50 percent of the energy required during the heating season and to determine the feasibility of using solar energy to power absorption-type…

This report documents the performance and conclusions of a 13-month period of monitoring the performance of the experimental solar heating and cooling system installed in the George A. Towns Elementary School, Atlanta, Georgia. The objectives of the project were to (1) make a significant contribution to solar design, technology, and acceptability;…

The average design effects for statistics estimated from the base-year National Longitudinal Study data are presented. Attempts to partition the effects into those due to stratification, clustering, and unequal weighting are discussed. The expected increases in subpopulation sample sizes due to oversampling are calculated and compared with the…

This guide is concerned with productivity measurement and improvement in mental health centers, and focuses on the relationship between service outputs and available clinical staff, i.e., staff productivity. Staff productivity measures are described as useful in identifying existing levels of productivity, making comparisons to determine the…

First-, third- and fifth-grade children participated in a study of information seeking, using a "Twenty Questions" procedure with a hierarchical array of pictures. Economy of inquiry increased with grade but was unaffected by practice, replaying a game, or observing a model. Age differences in types of questions reflected differences in…

Two methods of item selection were used to select sets of 40 items from a 50-item verbal analogies test, and the resulting item sets were compared for relative efficiency. The BICAL program was used to select the 40 items having the best mean square fit to the one parameter logistic (Rasch) model. The LOGIST program was used to select the 40 items…

Ninety-six male and female college students participated in an experiment designed to examine the feasibility of isolating the critical attributes in a given instructional example as an error correction mechanism for the purpose of improving instructional effectiveness and efficiency. Results indicated that although students with the critical…

The four purposes of this study were: (1) To compare two versions of a tailored testing model similar to one suggested by Kalisch (1974); (2) To identify levels of the variables within the two versions, which produce an efficient tailored testing procedures; (3) To compare, within each version, the results obtained when employing relatively small…

Two tailored testing models, specifying procedures by which the correctness of examinees' responses to a fixed number of test items are predicted by presenting as few items as possible to the examinee, were compared for their efficiency. The models differ in that one requires reconsideration of each prediction whenever additional information is…

This report describes the activities and recommendations of a study team that attempted to reform the Korean educational system to increase its efficiency and make it more responsive to the nation's needs. Using a systems approach, the study team collected historical, cultural, and educational data, including demographic reports, economic…

This book examines the advantages and disadvantages of various methods of financing education and discusses the basic issues related to increasing efficiency in education. Section 1 offers a short history of educational finance and discusses many of the traditional approaches to financing education. Section 2 presents methods for distributing…

The report provides additional amplification for the concepts, purposes, techniques, and procedures of economic analysis. It also focuses on and discusses potential difficulties one is likely to encounter in doing an economic analysis. The key elements of the process are discussed in detail: (1) establishing and defining objectives, (2)…

The first section of this report defines and discusses the concept of productivity in education, reviews methods used to identify community college outputs and conversion factors, and reviews possible approaches to productivity management. The second section describes the step-by-step procedure used by the Dallas County Community College District…
