This study examines the potential of the ZINinNGT app, a mobile learning application designed to support hearing parents of deaf and hard-of-hearing (DHH) children in learning Dutch Sign Language. We conducted interviews with ten parents to investigate their current sign language learning experiences and to gather feedback on the ZINinNGT prototype. While results indicated that an app cannot overcome many of the challenges parents face, parents still expressed a very positive attitude towards using a sign language learning app. Feedback on the ZINinNGT prototype identified the need for enhanced usability and a desire to include quizzes and information on the handshapes of signs. Overall, feedback was very positive, indicating that a mobile app has the potential to support hearing parents by providing relevant content going beyond vocabulary level.

This paper investigates a generalized version of inquisitive semantics (Groenendijk, 2008b; Mascarenhas, 2008). A complete axiomatization of the associated logic is established. The connection with intuitionistic logic is clarified and heavily exploited.
