Although robots' social behaviors are known for their capacity to facilitate learner-robot interaction for language learning, their application and effect have not been adequately explored. This study reviewed 59 empirical articles to examine the contexts and application of various social behaviors of robots for language learning, and conducted a…

Although automated spoken language assessment is rapidly growing, such systems have not been widely developed for signed languages. This study provides validity evidence for an automated web application that was developed to assess and give feedback on handshape and hand movement of L2 learners' Swiss German Sign Language signs. The study shows…

This study explores whether middle-school students can exploit explicitly addressed crosslinguistic lexical similarities between German and English to learn vocabulary more efficiently. Across six weeks, 260 Swiss German learners of English as a foreign language (17 classes) completed three vocabulary learning tests (T1, T2 and T3). Additionally,…

Sign languages present particular challenges to language assessors in relation to variation in signs, weakly defined citation forms, and a general lack of standard-setting work even in long-established measures of productive sign proficiency. The present article addresses and explores these issues via a mixed-methods study of a human-rated…

Taking a contextual approach to research on language learner beliefs, this longitudinal study of 49 Swiss university students learning Danish as a foreign language investigates how and why the participants change their beliefs over time. At the beginning of the three-semester language course, the participants believe that form-focussed approaches…

The main goal of this paper is to analyze how the age factor behaves as an alleged individual difference (ID) variable in SLA by focusing on the influence that the learning context exerts on the dynamics of age of onset (AO). The results of several long-term classroom studies on age effects will be presented, in which I have empirically analyzed…

This study was designed to investigate the effects of age of onset and type of instruction on ultimate EFL attainment at the end of the period of normal schooling in Switzerland, measured in terms of written fluency, complexity, morphosyntactic accuracy, vocabulary size, and listening skills. Data were gathered from four groups of 18-year-old…
