How can we identify authentic reading material that matches the learner's proficiency and fosters their language development? Traditionally, this involves assigning a one-dimensional label to the text that identifies the grade or proficiency level of the learners that the text is intended for. Such an approach is inadequate given that both the…

Chatbots, whose potential for language learning have caused controversy among Second Language Acquisition (SLA) researchers (Atwell, 1999; Fryer & Carpenter, 2006; Fryer & Nakao, 2009; Parker, 2005, Coniam, 2014; Jia, 2004; Chantarotwong, 2005) are intelligent conversational systems stimulating human interlocutors with voice or text. In…

We present an intelligent tutoring system that lets students of Chinese learn words and grammatical constructions. It relies on a Bayesian, linguistically motivated cognitive model that represents the learner's knowledge. This model is dynamically updated given observations about the learner's behaviour in the exercises, and employed at runtime to…

Vocabulary plays an important part in second language learning and there are many existing techniques to facilitate word acquisition. One of these methods is code-switching, or mixing the vocabulary of two languages in one sentence. In this paper the authors propose an experimental system for computer-assisted English vocabulary learning in…

This article discusses design and usability issues pertaining to context-sensitive "help" in computer-assisted language learning (CALL). As part of the discussion, we present a study in which we examined the effects of three independent factors on student usage of context-sensitive "help": feedback, exercise type, and language proficiency. Forty…

Investigates the effectiveness of two types of computer feedback: one is traditional computer feedback that indicates only missing or unexpected words in the learner's response, and the other is intelligent computer feedback that provides further information about the nature of the errors in the form of metalinguistic rules.
