The document discusses the benefits of using pairwork and groupwork in the communicative classroom. It argues that these activities 1) motivate students by providing meaningful face-to-face interactions that resemble real-world communication, 2) increase opportunities for language practice as students can interact in smaller groups, and 3) allow students to monitor their understanding and be understood by interacting with classmates. Additional benefits include helping build understanding as students can discuss with peers and giving students more freedom in a learner-centered approach. Potential disadvantages are that the teacher may not see all student participation and shy students could feel frustrated, but providing a relaxing atmosphere can help address this.
