Adaptive comparative judgment (ACJ) has been widely used to evaluate classroom artifacts with reliability and validity. In the ACJ experience we examined, students were provided a pair of images related to backpack design. For each pair, students were required to select which image could help them ideate better. Then, they were prompted to provide…

Research on first language (L1) attrition typically focuses on immigrant populations in their second language (L2) environment, yet we know comparably little about L1 attrition in the L1 setting. This study used two lexical tasks to test L1 attrition, a time-sensitive word decision task and a video retelling. Chinese teachers of English vs.…

This study provides an empirical approach to utilizing an Artificial Intelligence (AI)-based system for identifying students' university choice factors that impact their matriculation decision. We created an AI-based chatbot that gathered both qualitative and quantitative data from nearly 1200 participants worldwide. The entire human-AI…

This paper investigates the role of interpreters in addressing cultural differences in the context of a cross-cultural collaborative teacher professional development project. Based on positioning theory, this study employed interpreter-mediated interactions and interviews to reveal the complex roles that interpreters played when interpreting…

As with all learners, English learners (ELs) require more than basic reading and writing skills to successfully engage with rigorous academic content, progress through school, and be fully prepared for postsecondary education and careers. ELs must be able to access grade-level content while simultaneously developing proficiency and autonomy in…

We explore the effectiveness of a simple algorithm for adaptively deciding whether to further decompose a step in a line of reasoning during tutorial dialogue. We compare two versions of a tutorial dialogue system, Rimac: one that always decomposes a step to its simplest sub-steps and one that adaptively decides to decompose a step based on a…

Usage-based approaches to second language acquisition put a premium on the linguistic input that learners receive and predict that any sequences of words that learners encounter frequently will experience a processing advantage. The current study explores the processing of high-frequency sequences of words known as 'lexical bundles' in beginner…

Purpose: This study investigated the relative utility of linguistic and nonlinguistic processing speed tasks as predictors of language impairment (LI) in children across 2 time points. Method: Linguistic and nonlinguistic reaction time data, obtained from 131 children (89 children with typical development [TD] and 42 children with LI; 74 boys and…
