Hua-hua Chang
Professor
My current research focuses on both theoretical development and applications of item response theory (IRT). These include computer-based assessment, automated test assembly (ATA), differential item functioning (DIF), cognitive diagnostic measurement, and patients reported outcome. Today one of the main challenges in Educational Measurement is to develop theories and methods for the new mode of large scale implementation of computerized assessment. More recently I have been concentrating on developing item selection methods for computerized adaptive testing (CAT). Several new methods have been developed, such as the a-stratified method, the global information method, and the constraint weighted information (CWI) method.more information...
Kiel Christianson
Associate Professor
Kiel Christianson's research focuses on language comprehension and production. Specifically, he's interested in how people arrive at interpretations of language input, especially when those interpretations are not consistent with the input (i.e., misinterpretations) but still might be "good enough" for normal communication. This research is being extended to non-native speakers, aphasic speakers, and specialized content areas, such as math/physics word problems (STEM). He is also conducting research in bilingual sentence processing and production, visual word recognition and reading, and psycholinguistics in several other languages.more information...
Gary Cziko
Professor Emeritus
My past research has focused on first and second language acquisition, language assessment, bilingual education, research methods, and the application of evolutionary theory and perceptual control theory to understanding human behavior, learning and education. I am currently focusing my research activities on what I call Autonomous Technology-Assisted Language Learning (ATALL). ATALL involves using and developing technology, in particular Internet media and communication tools, to enhance education in foreign-languages and cultures.more information...
