Everybody is talking about RIGOR or asking, "What is rigor?" If you do any research on rigor, you will find that rigor does not mean difficulty. Instead rigor means the level of mental processing that must occur to answer a question, perform a task or generate a product. Two widely used measures of rigor are Bloom's Taxonomy and Webb's Depth of Knowledge Levels. Bloom's verbs indicate the level of performance or the level of questioning. Webb's Depth of Knowledge focuses on the complexity of standards in order to successfully complete an assessment or a task. The outcome (product) is the focus of the depth of understanding. I have created DOK posters that include a description of the level of understanding but also the questioning stems. Enjoy!
