PDF on ERIC Download full text
Reardon, Sean F.; Kalogrides, Demetra; Ho, Andrew D. – Stanford Center for Education Policy Analysis, 2017
There is no comprehensive database of U.S. district-level test scores that is comparable across states. We describe and evaluate a method for constructing such a database. First, we estimate linear, reliability-adjusted linking transformations from state test score scales to the scale of the National Assessment of Educational Progress (NAEP). We…

Applying Informetric Characteristics of Databases to IR System File Design, Part I: Informetric Models.
Peer reviewed Peer reviewed
Wolfram, Dietmar – Information Processing and Management, 1992
Examines how informetric characteristics of information retrieval (IR) system databases can be used to help system designers decide what type of file structures would provide the best performance. The development of appropriate models describing database contents is highlighted in this first part of a two-part study. (30 references) (LRW)

Applying Informetric Characteristics of Databases to IR System File Design, Part II: Simulation Comparisons.
Peer reviewed Peer reviewed
Wolfram, Dietmar – Information Processing and Management, 1992
This second report on a two-part study on the application of informetrics to information retrieval (IR) system design used models of database contents in a factorial simulation study at the University of Western Ontario. The study explored whether different file structures were better suited for different informetric environments. (32 references)…
