This webinar by TEFLorg addresses teaching mixed-ability English as a Foreign Language (EFL) classes. The presenter, a teacher trainer with extensive experience, discusses the common causes of mixed-ability classes (e.g., business needs, insufficient level testing), and the challenges they pose (e.g., maintaining engagement, managing classroom dynamics). Solutions offered include differentiated instruction, peer learning, varied activities, and flexible grouping, emphasizing the importance of frequent rotation and individual assessment rather than class-wide comparisons. Technology and graded readers are also suggested as helpful resources.
