In this article an application of conformal mapping to aerofoil theory is studied from a geometric and calculus point of view. The problem is suitable for undergraduate teaching in terms of a project or extended piece of work, and brings together the concepts of geometric mapping, parametric equations, complex numbers and calculus. The Joukowski…

Homogeneity of variance (HOV) is a major assumption underlying the validity of many parametric tests. More importantly, it serves as the null hypothesis in substantive studies that focus on cross- or within-group dispersion. Despite a widely acknowledged need for testing HOV, very few textbooks give adequate coverage on the topic, and many HOV…

Guidelines are offered for the use of progress and outcome measures as an integral part of: (1) treatment planning and progress review; (2) clinical supervision; and (3) program management. Scales with documented reliability and validity are listed. Some sources of computer software programs for scoring are given. (Author/LMO)

Explains two microcomputer programs written in BASIC for the Apple IIe microcomputer which allow the user to evaluate the Wechsler Intelligence Scale for Children-Revised and choose recommendations to fit the individual needs of the client being tested. (MBR)

Ten different methods of using computer administered tests in college level biology are described: evaluation (or posttest), student self-evaluation, student self-remediation, class remediation, individual student remediation, pretesting, identification of problem areas, immediate feedback, group testing, and remote site testing. (Author/MBR)

There are a number of issues to consider in choosing tests, including alignment of tests and standards, the integration of tests with curriculum and instruction, the quality of the tests, and a clear definition of the purpose of the test. To address the various needs reflected by these issues, PLATO Learning, Inc., offers two curriculum-wide…

Explores various issues related to empirical validation of computer documentation. Topics discussed include developing validation test items; selecting test users; costs; benefits of testing for the writer; the role of the writer and editors; conducting the validation test; and writing revision specifications. (LRW)

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)

In the summer of 1996, the U.S. Armed Services will implement the computerized adaptive testing version of the Armed Services Vocational Aptitude Battery (CAT-ASVAB). When conversion is completed at the 65 targeted military entrance processing stations, about half the applicants will take this test version. This paper describes the efforts that…

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,…

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:…
