The document discusses several approaches to teaching foreign languages: - The teacher-centered approach focuses on the teacher's control and students learning individually with little collaboration. - The collaborative approach emphasizes language skills, sharing understanding, teamwork and group discussions. - The learner-centered approach engages and motivates students by giving them some control over their learning and encouraging collaboration between teachers and students. - The problem-based approach involves students discovering what they need to learn by examining their existing knowledge and stating/defending positions. - The integrated approach uses multi-disciplinary teams to take on tasks in a single project.
