Substantial progress has been made toward applying technology enhanced conversation-based assessments (CBAs) to measure the English-language proficiency of English learners (ELs). CBAs are conversation-based systems that use conversations among computer-animated agents and a test taker. We expanded the design and capability of prior…

In experiments with univalent target stimuli, task-switching costs can be eliminated if participants are unaware of the task rules and apply cue-target-response associations. However, in experiments with bivalent target stimuli, participants show task-switching costs. Participants may exhibit switch costs even when no task rules are provided in…

We investigated how young language learners process their responses on and perceive a computer-mediated, timed speaking test. Twenty 8-, 9-, and 10-year-old non-native English-speaking children (NNSs) and eight same-aged, native English-speaking children (NSs) completed seven computerized sample TOEFL® Primary™ speaking test tasks. We investigated…

Automated writing evaluation (AWE) systems can provide immediate computer-generated quantitative assessments and qualitative diagnostic feedback on an enormous number of submitted essays. However, limited research attention has been paid to locally designed AWE systems used in English as a foreign language (EFL) classroom contexts. This study…
