This document summarizes a study that investigated how high school math teachers interpret and apply Bloom's Taxonomy of higher-order thinking skills. The study asked 32 teachers to define higher- and lower-order thinking, identify which thinking skills in Bloom's Taxonomy represent each, and create exam questions for each skill level. The results showed teachers have difficulty interpreting Bloom's Taxonomy and creating questions that assess higher-order thinking, suggesting alternatives are needed to help teachers evaluate these skills.
