Activity: "Reliability Case Clinic" (Group - 60 mins). Task: Divide into groups of 4. Each group is assigned a different type of reliability (e.g., Inter-rater Reliability). They must find a real-world educational example where this reliability type is critical (e.g., scoring an oral presentation), explain how it is ensured, and propose a strategy to improve it. Use a shared Google Slide deck (one slide per group) to compile findings. (Group work: 45 mins. Quick group share: 15 mins).
