The document describes a collaborative German language learning tutor called GermanTuTalk that uses a job interview scenario to teach students vocabulary, grammar rules, and conversational skills necessary for a job interview. The tutor interacts with two students and guides them in correctly forming sentences in German by correcting their responses. The system architecture of GermanTuTalk is modeled using TuTalk and includes components like a tutoring model, planner, and script to facilitate conversations between the students and tutor.
