The SL-ReDu Environment for Self-monitoring and Objective Learner Assessment in Greek Sign Language.

Here we discuss the design and implementation features of a platform aiming to provide two distinct modules for self-monitoring and objective assessment of learners of the Greek Sign Language (GSL) as L2. The platform is designed according to user needs of both learners and instructors. It incorporates the educational content of the A0 and A1 levels of CEFR. The platform provides a user-friendly environment that guarantees improvement of learner’s skills, objectivity in learner assessment and enhanced SL knowledge grading. Active learner language production is assessed via an innovative SL recognition engine, while standard multimedia-based drills assess learners’ comprehension skills.
