Describes the construction of a wave generator used to review the algebraic relationships of wave motion. Students calculate and measure the weight needed to create tension to generate standing waves at the first eight harmonics. (MDH)

This document proves that the F statistic can be obtained by squaring t-test values, or that equivalent t-test values may be obtained by extracting the positive square roots of F values. Proof to varying degrees of completeness and accessibility has been given by other scholars, but generally these prior statements, particularly those available to…

A study of possible modifications to the Chapter 1 formula examined whether such change might better target the federal funds to the needs of low-achieving students in high poverty areas. The study used data from a national evaluation of Chapter 1. The data underwent a multiple regression analysis focusing on the relationship between low…

"Item models" (LaDuca, Staples, Templeton, & Holzman, 1986) are classes from which it is possible to generate/produce items that are equivalent/isomorphic to other items from the same model (e.g., Bejar, 1996; Bejar, 2002). They have the potential to produce large number of high-quality items at reduced cost. This paper introduces…

This book is designed for those interested in the teaching of mathematics, in both first language and second language contexts, and is based on 15 years' teaching experience in Africa and Asia. The book is designed to present the main issues of language in mathematics teaching, and is therefore not a highly technical work. Chapters included are:…

Computer Algebra Systems (CAS) are computer systems for the exact solution of problems in symbolic form. The newspaper is designed to serve as a conduit for information and ideas on the use of CAS in education, especially in lower division college and university courses. Articles included are about CAS programs in several colleges, experiences…

Formed by the Connecticut legislature to monitor the state's educational aid plan, the Educational Equity Study Committee in this report joins with the state Board of Education in recommending amendments to Connecticut's 1979 school finance reform law, involving changes in the state's Minimum Expenditure Requirement (MER) plan and Guaranteed Tax…

As a response to the concerns associated with the allocation of state resources to institutions of higher education, several states have developed budget formulas to derive estimates of the institutional financial requirements. Formulas, however, were developed during a period of rapid growth, and might be unresponsive to institutional needs…

A research project is described that concerns "temporal adjustment" as one form of a non-wage adjustment in the academic labor market. Receipt of the doctorate, the number and length of post-doctoral fellowships, and the achievement of tenure are temporal factors in academic careers. The change in timing of these factors is a form of…

Designed for educational planners and decision makers, this report reviews the principles and methods of demography. The first section discusses demographic rates and measures, including a basic demographic equation, crude rates, cohort measures, parity progression ratio, and life tables. The next three sections examine three demographic factors…

The increase in tuition and expenditures at Montgomery College were analyzed through the use of the Higher Education Price Index (HEPI) based upon 1967 dollars. This index gives an indication of the effect of inflation upon a given amount of goods and services. Application of the HEPI to Montgomery College data since 1967 reveals that tuition for…

The relationship between departmental activities and the need for nonacademic staff and operating funds was analyzed using regression analysis. Support costs were broken into task categories and related to certain basic variables describing the composition and activity of the unit (e.g., number of staff and teaching load). The results were linked…

Eight different methods are reviewed for determining whether two or more tests are equivalent measures. These methods vary in restrictiveness from the Wilks-Votaw test of compound symmetry (which requires that all means, variances, and covariances are equal), to Joreskog's theory of congeneric tests (which requires only that the tests are measures…

Presents a quantitative method developed at Stanford University that allows administrators to accurately assess the future capital requirements necessary for renewal and replacement of campus buildings. (MLF)

Patterns of government financing of universities and institutional finance in the United Kingdom were studied. Formulas used in allocating resources for administration, services, salaries, maintenance, facilities, and equipment are reported in some detail, and funding patterns are illustrated in charts. (MSE)
