A model-testing approach for evaluating the stability of item response theory item parameter estimates (IPEs) in a pretest-posttest design is illustrated. Nineteen items from the Head Start Measures Battery were used. A moderately high degree of stability in the IPEs for 5,510 children assessed on 2 occasions was found. (TJH)

Describes the workings of computerized adaptive testing (CAT). Focuses on the key concept of information and then discusses two important components of a CAT system: the calibrated item bank and the testing algorithm. Describes a CAT that was designed for making placement decisions on the basis of two typical test administrations and notes the…

Over four weeks, 81 secondary students with learning disabilities were tested on four parallel mathematics performance assessments, each under a different condition: standard administration, teacher-read, computer-read, and computer-read with video. Results indicated that providing a reader, either human or computer, increased scores on…

Gateway tests provide a means of assuring that students in reformed precalculus and calculus courses acquire the algebraic and computational skills needed in courses following these, while allowing the focus of the course to be on the conceptual understanding intrinsic to the reformed courses. However, logistical difficulties plague the…

Nicotine replacement therapy (NRT) repeatedly has been shown to improve smoking treatment outcome. The major mechanism posited for this improvement in outcome is that NRT reduces nicotine craving and withdrawal. The authors tested this hypothesized mechanism of action using real-time data on craving and withdrawal, collected by ecological…

This article describes the translation goals, challenges, strategies, and solutions employed in the development of a computer-based, self administered, psychiatric diagnostic instrument, the Diagnostic Interview Schedule for the Deaf (D-DIS-IV) in American Sign Language (ASL) with English captions. The article analyzes the impact of the…

Educators in Europe are complaining about mishandled changes in a key English-language test and are demanding that the Educational Testing Service (ETS), which runs the examination, delay plans to introduce its new online format in March 2006 in more than 100 countries. Critics of the planned change in the Test of English as a foreign Language…

The Scan-Tron Forms Analysis Package (SFAP) is a collection of integrated programs that allow an IBM-PC (or compatible) to collect data from a Scan-Tron 1200 forms reader. In addition to the basic data acquisition capability, the SFAP has additional capabilities related to the viewing and formatting of incoming data. When used in combination with…

Concerns about Internet-based career assessments include the following: users' technical skill level, lack of screening, psychological factors, cultural bias, unprotected results, technical failures, lack of standardization, digital divide, interpretation problems, outdated tests, copyright violations, administrator qualifications, and hidden…

The use of computer-based test interpretation (CBTI) in career assessment raises numerous ethical and professional issues: How do current standards apply to Internet tests? What are appropriate and inappropriate uses of CBTI? How can it be used in career counseling? Who is qualified to use CBTI? and What are the potential benefits and problems?…

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…

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…

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…

In the past decade, researchers have attempted to develop computer-assisted learning and testing systems to help students improve their learning performance. Conventional testing systems simply provide students with a score, and do not offer sufficient information in order to improve their learning performance. It would be of more benefit to…
