  We introduce a novel category of GC-agents capable of functioning as both
teachers and learners. Leveraging action-based demonstrations and
language-based instructions, these agents enhance communication efficiency. We
investigate the incorporation of pedagogy and pragmatism, essential elements in
human communication and goal achievement, enhancing the agents' teaching and
learning capabilities. Furthermore, we explore the impact of combining
communication modes (action and language) on learning outcomes, highlighting
the benefits of a multi-modal approach.
