Discusses computerized testing and certification and proposes three levels of certification testing, each one corresponding to a different notion of competent performance, from basic knowledge to expert performance. Declarative and procedural knowledge are defined; performance-based tests are discussed; and testing for problem-solving ability is…

Discusses problems of diagnosing and repairing infeasible linear-programming models in computerized test assembly. Demonstrates that it is possible to localize the causes of infeasibility, although this is not always easy. (SLD)

Responds to an article on computerized adaptive second language (L2) testing, expressing concerns about the appropriateness of such tests for informing language educators about the language skills of L2 learners and users and fulfilling the intended purposes and achieving the desired consequences of language test use.The authors of the original…

Suggests that because of the nonlinear relationship between item usage and item security, the problems of test security posed by continuous administration of standardized tests cannot be resolved merely by increasing the size of the item pool. Offers alternative strategies to overcome these problems, distributing test items so as to avoid the…

Reviewed methods of estimating theta suitable for computerized adaptive testing (CAT) and discussed the differences between Fisher and Kullback-Leibler information criteria for selecting items. Examined the accuracy of different CAT algorithms using samples from the National Assessment of Educational Progress. Results show when correcting for…

Proposed a refinement, based on the stratification of items developed by D. Weiss (1973), of the computerized adaptive testing item selection procedure of H. Chang and Z. Ying (1999). Simulation studies using an item bank from the Graduate Record Examination show the benefits of the new procedure. (SLD)

Discusses the potential positive and negative effects computer-based testing could have on validity, reviews the literature on validation perspectives in computer-based testing, and suggests ways to evaluate the contributions of computer-based testing to more valid measurement practices. (SLD)

This study examined the utility of Web-based quizzing. We assigned 3 classes to a no-quiz, in-class quiz, or Web-based quiz condition. Midsemester results demonstrated a positive effect for in-class quizzing but not Web-based quizzing. After several adjustments in quiz presentation and duration, the Web-based group increased exam performance to a…

In addition to its precision superiority over nonadaptive tests, another known advantage of computerized adaptive tests (CATs) is that they can be offered on a continuous basis. This is advantageous to examinees in terms of flexibility of test scheduling, as well as advantageous to schools and other testing centers in terms of both space and…

Researchers at Emory University and the University of North Carolina at Chapel Hill are seeking an answer to whether the Internet can help save the life of a suicidal student. A study conducted at both colleges gauged the effectiveness of anonymous online depression-screening questionnaires and results indicate that the surveys helped counselors…

Assessing the language development of bilingual children can be a challenge--too often, children in the complex process of learning both Spanish and English are under- or over-diagnosed with language disorders. SLPs can change that with "SALT 2010 Bilingual S/E Version" for grades K-3, the first tool to comprehensively assess children's language…

Formative assessment has recently become a focus of renewed research as state and federal policy-makers realize that summative assessments have reached a point of diminishing returns as a tool for increasing student achievement. Consequently, supporters of large-scale testing programs are now beginning to consider the potential of formative…

In recent years, the Educational Testing System organisation has developed two models of the computer-based Test of English as a Foreign Language (TOEFL). However, the computerization of the test has shown a number of problems according to the testees' origin. This paper suggests some of these problems after conducting short interviews with four…

The use of web-based software and course management systems for the delivery of online assessments in the chemistry classroom is becoming more common. IMMEX software, like other web-based software, can be used for delivering assessments and providing feedback, but differs in that it offers additional features designed to give insights and promote…

The work aims to improve the assessment of creative problem-solving in science education by employing language technologies and computational-statistical machine learning methods to grade students' natural language responses automatically. To evaluate constructs like creative problem-solving with validity, open-ended questions that elicit…
