Argues that, although expert systems--which are supposed to give users all the advantages of consulting with human experts--can be useful for medical diagnosis, where tests tend to be reliable, they can be hazardous in such areas as psychological testing, where test reliability is difficult to measure. (MBR)

Comments on Kerwin et al.'s article on Covariance Structure analysis (LISREL). Concerns include assumptions about requirements for causal inferences, psychometric properties of measurement scales, validity of the indicators of each latent variable, completeness of the structural model, linearity of the latent variables, and the joint distribution…

Presents the Reading Estimate Program, which follows the same procedure as the Raygor Estimate for determining readability. (CRH)

Attempts to distill a growing technical literature on repeated-measures analysis of variance into a few simple principles for selecting an analytic technique. Argues that researchers ought not opt for a general analysis strategy when current computer technology makes it possible to select the optimal analysis technique for a given data set. (RH)

Discussion of user-friendly documentation focuses on problems with computer hardware and software documentation, and other forms of instructional manuals, that are poorly written and do not keep the needs of the users in mind. Topics highlighted include target audience analysis and validation and indexes. (LRW)

Discusses ethical and professional issues in psychology regarding computer-assisted therapy (CAT). Topics addressed include an explanation of CAT; whether CAT is psychotherapy; software, including independent use, validation of effectiveness, and restricted access; clinician resistance; client acceptance; the impact on ethical standards; and a…

Describes what a computer-adaptive test (CAT) is, examines its roots, and points out some of the challenges this approach to assessment presents. (Author/VWL)

Evaluates the Computer-Based Assessment Instrument (CRAI) as a test for reading proficiency. Notes strengths of CRAI, including its use as a quick assessment of silent reading comprehension level, and the problems with readability and content specific words lists and the lack of scoring features. (JC)

Provides a framework for understanding the concept of validity and how it applies to simulation research. Extant tests of validity are discussed in terms of this framework, and a general schema for testing validity is proposed. (MBR)

Discusses the possible limitations and the advantages of computer-assisted language testing and several test variables which are of concern in determining test validity. The concept of computer-adaptive testing and its relationship to these variables is described. (SED)
