DeCarlo, Lawrence T. – ETS Research Report Series, 2008
Rater behavior in essay grading can be viewed as a signal-detection task, in that raters attempt to discriminate between latent classes of essays, with the latent classes being defined by a scoring rubric. The present report examines basic aspects of an approach to constructed-response (CR) scoring via a latent-class signal-detection model. The…

Green, Bert F. – 2002
Maximum likelihood and Bayesian estimates of proficiency, typically used in adaptive testing, use item weights that depend on test taker proficiency to estimate test taker proficiency. In this study, several methods were explored through computer simulation using fixed item weights, which depend mainly on the items difficulty. The simpler scores…

Chung, Gregory K. W. K.; Herl, Howard E.; Klein, Davina C. D.; O'Neil, Harold F., Jr.; Schacter, John – 1997
This report examines issues in the scale-up of assessment software from the Center for Research on Evaluation, Standards, and Student Testing (CRESST). "Scale-up" is used in a metaphorical sense, meaning adding new assessment tools to CRESST's assessment software. During the past several years, CRESST has been developing and evaluating a…

Bennett, Randy Elliot; Persky, Hilary; Weiss, Andrew R.; Jenkins, Frank – National Center for Education Statistics, 2007
The Problem Solving in Technology-Rich Environments (TRE) study was designed to demonstrate and explore innovative use of computers for developing, administering, scoring, and analyzing the results of National Assessment of Educational Progress (NAEP) assessments. Two scenarios (Search and Simulation) were created for measuring problem solving…

Chung, Gregory K. W. K.; Baker, Eva L. – 1997
This report documents the technology initiatives of the Center for Research on Evaluation, Standards, and Student Testing (CRESST) in two broad areas: (1) using technology to improve the quality, utility, and feasibility of existing measures; and (2) using technology to design and develop new assessments and measurement approaches available…
