Benjamin Bloom was an American educational psychologist best known for creating the Bloom's Taxonomy, a framework that classifies educational goals and objectives. Developed in 1956, this taxonomy helps educators design curriculum and assess student learning by categorizing cognitive skills into levels, from basic knowledge to higher-order thinking. Bloom's work emphasized the importance of critical thinking and problem-solving in education. His research has influenced teaching methods and assessment practices worldwide, making it easier for teachers to evaluate student progress and adapt their instruction to meet diverse learning needs.
