Gaia · AI tutor

Gaia asks before it answers.

Gaia is a multi-agent conversational tutor developed in L2BGreen. It guides learners through real business cases, gives hints first and reveals answers only once they have stretched their own thinking.

One tutor, four agents

Gaia runs as an interaction engine. Each agent takes care of one pedagogical job.

  1. Present the case

    The case agent sets the scene: a real company, a real decision.

  2. Scaffold knowledge

    Hints and follow-up questions come before any answer.

  3. Support application

    Learners apply concepts to the case and to their own plans.

  4. Feedback on arguments

    Argumentation-aware feedback points out gaps in reasoning.

Built on

  • Case-based learning
  • Bloom's taxonomy
  • Socratic scaffolding
  • AI-supported feedback

What 25 students showed us

25+messages per week

Findings

  • Engagement stayed high, and student messages increased significantly from the first to the third case.
  • Students rated the usability and the learning materials positively.
  • Learners with less prior orientation toward green entrepreneurship talked longer with Gaia.

What we change next

  • Some found the text-only format tiring, so dialogues will become shorter and more focused.
  • Next step: multimodal interaction beyond text.

One of the most encouraging findings is that learners did not only complete the activities, but actively interacted with Gaia.
