Taxonomy means a scientific process of classifying things and arranging them into groups. Learning objectives are statements of what a learner is expected to know, understand, and/or be able to demonstrate after completion of a process of learning. In 1956, Benjamin S. Bloom (1913–1999) and a group of educational psychologists developed a hierarchy of educational objectives, which is generally referred to as Bloom’s Taxonomy, and which attempts to identify six levels within the cognitive domain, from the simplest to the most complex behavior, which includes knowledge, comprehension, application, analysis, synthesis, and evaluation. Bloom’s Taxonomy refers to a classification of the different learning objectives that educators set for learners.
