This document provides a guide for observing, participating in, and reflecting on classroom lessons. It discusses Bloom's taxonomy of cognitive skills and how it can be used to analyze the cognitive level of questions teachers ask. The taxonomy ranges from lower levels like memory and comprehension to higher levels such as analysis, synthesis and evaluation. It also presents Sanders' adaptation of Bloom's taxonomy, which identifies 7 levels of questions from least to most complex. The document encourages observers to examine the types of questions teachers ask using these frameworks to assesswhether higher-level questions are being utilized.
