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…

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…

A renewed focus on foreign language (FL) learning and speech for communication has resulted in computer-assisted language learning (CALL) software developed with Automatic Speech Recognition (ASR). ASR features for FL pronunciation (Lafford, 2004) are functional components of CALL designs used for FL teaching and learning. The ASR features…

In this article, Structural communication grid (SCG), an alternative measurement and evaluation technique, has been firstly summarised and the design, development and implementation of a computer based SCG system have been introduced. The system is then tested on a sample of 154 participants consisting of candidate students, science teachers and…

The complex nature and uncertain information in social problems required the emergence of fuzzy decision support systems in social areas. In this paper, we developed user-friendly Fuzzy Group Decision Support Systems (FGDSS) software. The software can be used for multi-purpose decision making processes. It helps the users determine the main and…
