This paper defines Bayesian network models and examines their applications to IRT-based cognitive diagnostic modeling. These models are especially suited to building inference engines designed to be synchronous with the finer grained student models that arise in skills diagnostic assessment. Aspects of the theory and use of Bayesian network models…

Computer adaptive testing is the study of scoring tests and questions based on assumptions concerning the mathematical relationship between examinees' ability and the examinees' responses. Adaptive student tests, which are based on item response theory (IRT), have many advantages over conventional tests. We use the least square method, a…

Technology today offers many new opportunities for innovation in educational assessment through rich new assessment tasks and potentially powerful scoring, reporting and real-time feedback mechanisms. One potential limitation for realizing the benefits of computer-based assessment in both instructional assessment and large scale testing comes in…

Automated Essay Scoring (AES) is defined as the computer technology that evaluates and scores the written prose (Shermis & Barrera, 2002; Shermis & Burstein, 2003; Shermis, Raymat, & Barrera, 2003). AES systems are mainly used to overcome time, cost, reliability, and generalizability issues in writing assessment (Bereiter, 2003; Burstein,…

E-rater[R] has been used by the Educational Testing Service for automated essay scoring since 1999. This paper describes a new version of e-rater (V.2) that is different from other automated essay scoring systems in several important respects. The main innovations of e-rater V.2 are a small, intuitive, and meaningful set of features used for…

This manual is intended to provide Illinois school districts with guidance in developing learning assessment plans and using testing materials as part of the school improvement program mandated by the 1985 educational reform legislation for Illinois. Designed primarily to be a series of "how to" booklets, the manual is divided into six…

According to the Committee on the Foundations of Educational Assessment, traditional educational assessment does a reasonable job of measuring knowledge of basic facts, procedures and proficiency of an area of the curriculum. However, the traditional approach fails to capture the breadth and richness of knowledge and cognition. Such a concern…

This article describes the placement testing program, the use of microcomputer software for scoring and analyzing test results, and the integration of the computerized test results into a comprehensive microcomputer-based student information system at the University of California, Irvine (UCI). UCI offers placement tests in five academic fields:…

Innovations, ETS's corporate magazine, provides information on educational assessment for educators, school leaders, researchers and policymakers around the world. Each issue of Innovations focuses on a particular theme in assessment. This issue reports on how new technologies in classrooms around the world are enhancing teaching, learning and…
