This document discusses the importance of questioning as a means of cross-border communication and collaboration. It presents three techniques for working with questions - creative questioning, map of questions, and positional questioning - which can help groups clarify interests, discuss differences, and self-organize. The document argues that the ability to raise and discuss meaningful questions should become a core modern skill, but it is currently lacking in education. It proposes integrating questioning techniques into project-based learning to help develop this skill.
