It notes that learning languages facilitates learning other skills, helps students understand other cultures, breaks down language barriers, and widens career opportunities. Learning languages is important because it adds diversity, builds on a globalized world, and allows collaboration and connectivity. The document also provides an example history lesson on World War I where students are split into groups representing different countries involved in the war.
