The type of processing-resource allocation (TOPRA) model predicts that the semantic processing of new second language (L2) words can impede the learning of their forms while structural processing can promote it. Using this framework, the present study examined the effects of processing type (semantic, structural, control), exposure frequency (one…

Language learners are underserved if there are unlearned meanings of a word that they think they have already learned. For example, "circle" as a noun is well known, whereas its use as a verb is not. For artificial-intelligence-based support systems for learning vocabulary, assessing each learner's knowledge of such atypical but common…

One of the most critical steps in the test development process is defining the construct, or the knowledge, skills, or abilities, to be assessed. This foundational step provides the basis for initial assumptions about the meaning of test scores and serves as a reference for subsequent validity research. In this paper, we describe the purpose of…
