Qualitative comparative analysis (QCA) is an empirical research method that has gained some popularity in the social sciences. At the same time, the literature has long been convinced that QCA is prone to committing causal fallacies when confronted with non-causal data. More specifically, beyond a certain case-to-factor ratio, the method is…

Much has been written about the importance of "writing with discipline" in order to increase the readability and, hence, the publishability of manuscripts submitted to journals for consideration for publication. More specifically, empirical evidence has been provided that links American Psychological Association (APA) errors, citation…

This study reports on the development, validation, and administration of a 48-item multiple-choice test to assess students' representational fluency of linear functions in a physics context (1D kinematics) and a mathematics context. The test includes three external representations: graphs, tables, and formulas, which result in six possible…

Sprego is programming with spreadsheet functions. The present paper provides introductory Sprego examples which have so far only been available in Hungarian. Spreadsheet environments offer both a programming tool which best serves beginner and end-user programmers' interest, and an approach which lightens the burden of coding and language details.…

This revised data file includes corrections that were provided to NCES as a result of a special collection effort designed to address data quality issues found in the 1a release of this file. In May 2012, NCES became aware of data errors for key data items for several schools on the published version of the SY 2009-10 school file; in some cases…

The 2012 edition of the "Digest of Education Statistics" is the 48th in a series of publications initiated in 1962. The "Digest" has been issued annually except for combined editions for the years 1977-78, 1983-84, and 1985-86. Its primary purpose is to provide a compilation of statistical information covering the broad field…

The 2011 edition of the "Digest of Education Statistics" is the 47th in a series of publications initiated in 1962. The "Digest" has been issued annually except for combined editions for the years 1977-78, 1983-84, and 1985-86. Its primary purpose is to provide a compilation of statistical information covering the broad field…

Evidence is given to indicate that Lawley's formulas for the standard errors of maximum likelihood loading estimates do not produce exact asymptotic results. A small modification is derived which appears to eliminate this difficulty. (Author)

Citations of 23 old papers in physics and physical chemistry were studied in 978 papers in which they appeared in 1974-1975. Using a new typology of reasons for citing the papers, it was determined that in about 60 percent of the cases, the papers are still being actively used. (Author/MBR)

Reports results of a study that examined Library of Congress topical subject headings and subdivisions in a large bibliographic database. Creation of a new machine-readable authority file of topical subdivisions and enhancements to the existing subject authority file are recommended to assist in assignment and validation of subdivided headings.…

A study examined the error rate of the "University of California Union Catalog Supplement," a 47 volume, computer produced book catalog of the materials cataloged by the nine University of California campuses during the years 1963-67. The study attempted not only to determine the rate and nature of errors, but also to develop a…

Investigated were the relationships among confidence judgments, latencies, and memory-trace strength." (Authors/MB)

This study was designed to replicate and extend Roberts' (1968) efforts at classifying computational errors. 198 elementary school students were administered an 84-item arithmetic computation test. Eight types of errors were described which led to several tentative generalizations. (Editor/RK)

Purpose of this study was to provide an analysis of errors performed on a sight-reading test administered to four college freshman piano classes at the end of their first semester of instruction. (Author)
