Abstract
ABSTRACT 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 good machine-internal and human-machine agreement through many-facet Rasch analysis. Learner perceptions examined through questionnaire responses indicate that the automated system occasionally generated ratings which impacted the quality of feedback at the level of individual signs for individual learners. Implications are discussed from a learning-oriented assessment perspective.
