The document discusses Bloom's Taxonomy, which is a framework for classifying educational goals and objectives into levels of complexity and specificity. It identifies three domains: cognitive, affective, and psychomotor. The cognitive domain deals with mental skills and knowledge. It was further broken down into six levels moving from basic recall to more complex skills of evaluation. The affective domain addresses growth in feelings and attitudes. The psychomotor domain involves physical skills and manual tasks. Later work expanded on Bloom's Taxonomy, especially in the psychomotor domain.
