The purpose of this study was to benchmark the types of Socratic questioning that were occurring in a Socrates Café, an online discussion forum, in a graduate-level diversity course in teacher education. The Universal Intellectual Standards were used to analyze Socratic questioning. Results suggested that the nine Universal Intellectual Standards provided an exceptional deductive framework for understanding the types and frequencies of Socratic questioning occurring in the Socrates Café. The benefits of using a Socrates Cafe discussion for instruction to scaffold critical thinking are discussed and implications for teacher education are considered.
