Self-efficacy is one's belief in one's capacity to organize and execute a course of action and serves as a motivating factor, since people tend to seek opportunities in areas where they feel efficacious and avoid areas where they believe they might fail (Bandura, 1997). Furthermore, as language learners' feelings of efficacy increase, so does the…

This paper provides a summary of a novel and integrated way to think about the item response models (most often used in measurement applications in social science areas such as psychology, education, and especially testing of various kinds) from the viewpoint of the statistical theory of generalized linear and nonlinear mixed models. In addition,…

The popularity of intelligent tutoring systems (ITSs) is increasing rapidly. In order to make learning environments more efficient, researchers have been exploring the possibility of an automatic adaptation of the learning environment to the learner or the context. One of the possible adaptation techniques is adaptive item sequencing by matching…

Based on the observation that scale-level methods are sometimes exclusively used to investigate measurement invariance for test translation, describes results of a simulation study investigating whether item-level differential item functioning (DIF) manifests itself in scale-level analyses such as single and multigroup factor analyses and per…

In this article, I describe a practical application of the Roussos and Stout (1996) multidimensional analysis framework for interpreting group performance differences on an ESL reading proficiency test. Although a variety of statistical methods have been developed for flagging test items that function differentially for equal ability examinees…

This article describes the development and validation of a listening questionnaire designed to assess second language (L2) listeners' metacognitive awareness and perceived use of strategies while listening to oral texts. The process of instrument development and validation is described, along with a review of the relevant literature related to…

Investigates the performance of students from different language backgrounds, using data from a computer-adaptive Japanese grammar test developed as a placement tool. Findings indicate item difficulties to be quite different for each group of candidates and imply that when candidates are from a different background from that of the trial…
