The document discusses the key elements and differences between the whole language approach and traditional approach to teaching grammar. According to the whole language approach, extension activities should allow for creative self-expression, not just fill-in-the-blank worksheets. They can include information gap activities, role-plays, games, projects, and simulations. Language learning is viewed as a thinking process where teachers design cognitively demanding activities that encourage students to hypothesize, predict, take risks, and self-correct. In contrast, the traditional approach sequences tasks simply to complexly and has more teacher-directed explanation and mastery of each step before moving to the next.
