This document discusses critical thinking skills for tutors. It defines critical thinking as using intelligence and knowledge to carefully explore situations and arrive at thoughtful conclusions based on evidence and reason. Tutors should model critical thinking and problem solving for students during sessions. They can get students to think critically by teaching them to ask relevant questions, examine ideas from different perspectives, and support conclusions with evidence. The document provides an example method ("GRASS") for analyzing problems and offers tips for making students independent learners after tutoring ends, such as providing step-by-step instructions for common problem types.
