The Revised Bloom’s Taxonomy: An Overview Lorin Anderson University of South Carolina A Fundamental Truth We don’t see the world as it is; we see the world through the lens through which we look at it. Bloom’s Taxonomy as a Framework A taxonomy of educational objectives “could do much to bring order out of chaos in the field of education. It could furnish the conceptual framework around which our descriptions of educational programs and experiences could be oriented. It could furnish a framework for the development of educational theories and research. It could furnish the scheme needed for training our teachers and for orienting them to the varied possibilities of education” (Bloom, 1949) Who were the taxonomists? Post World War II Students received course credit by passing the examinations (credit-by-examination) Quite obviously, the exams had to be based on course objectives (validity) and of sufficient length to be reliable. University Examiners Responsible for designing or helping to design end-of-course examinations They Needed a Set of Categories that Cut-Across Subject Areas “Although the objectives … may be specified in an almost unlimited number of ways, the student behaviors involved in these objectives can be represented by a relatively small number of classes. Therefore, the taxonomy is designed to be a classification of the student behaviors which represent the intended outcomes of the educational process” (p. 18). Looking Through a New Lens Evaluation Synthesis Analysis Application Comprehension Knowledge The Original Bloom’s “Bloom’sTaxonomy Taxonomy Without the Lens The student will recall the names of the parts of a flower. With the Lens The This student is a knowledge will recall the objective. names of the parts of a flower. Objectives were used to form categories; then categories were used to classify objectives. 80 % of the objectives fell into the Knowledge category The Revision Began in November 1996 Led by David Krathwohl Involved cognitive psychologists, curriculum theorists, teacher educators, and measurement and assessment specialists. Group met twice a year for four years. Draft completed in 2000; text published in 2001. Two books – soft cover for teachers and other “practitioners” and hard cover for academicians. In education, objectives are statements of what we want students to learn as a result of the instruction we provide. Standards are simply mandated objectives. The Common Format of Objectives Subject Verb S V Object O The SUBJECT is the Learner or the Student. The student (will) The student (should) The students (might) Quite often, the subject is implicit or understood. The verbs provide clues as to the cognitive process category intended by the person or persons writing the standard. Adopted from the original Bloom’s taxonomy of educational objectives, there are six cognitive process categories. Bloom • Evaluation Revised Bloom • Create • Synthesis • Evaluate • Analysis • Analyze • Application • Apply • Comprehension • Understand • Knowledge • Remember Each of the six cognitive process categories was divided into specific cognitive processes. Nineteen (19) specific cognitive processes were identified.

CREATE Generating Planning Producing Unlike the verbs, the objects of the standards are subject-specific (e.g., math, science, social studies). The objects specify the CONTENT of the standard. For several reasons, CONTENT was replaced by KNOWLEDGE. What are Differences Between Content and Knowledge? Content is subject-matter specific. If you focused on content, then, you would need as many taxonomies as there are subject matters (e.g., one for science, one for history, etc.). Content exists outside the student. A major problem, then, is how to get the content inside the student. When content gets inside the student, it becomes knowledge. This transformation of content to knowledge takes place through the cognitive processes used by the student.

CREATE Generating Planning Producing The SVO format of standards in combination with the twodimensional structure of the Taxonomy Table allows us to classify standards so we better understand their intent and meaning in terms of student learning. Additional Benefits Increase curriculum alignment Improve validity of assessments Improve quality of instruction Curriculum Alignment Assessments Objectives Curriculum Alignment Instructional Activities/ Materials Why is Alignment Important? Increases validity of assessment Increases students’ opportunity to learn Provides more accurate estimates of teaching effectiveness Permits better instructional decisions to be made Traditional Alignment What content is included in the objective? What content is included on the assessment(s)? Is the content included in the objective and/or on the assessment included in the instructional materials? If the content is the same, there is a high level of alignment.

Focus students’ attention on important facts and terms, using, among other things, study guides, colors, and verbal markers. 2. Structure the information to be remembered (e.g., outlines, diagrams, pictures). 3. Use repetition, incorporating songs and rhythmic activities (e.g., clapping, chanting, cheering). 4. Use mnemonic devices & acronyms; teach memory strategies (e.g., rehearsal, elaboration, making connections with familiar places and things). 5. Use distributed practice. Teaching Students to "Understand Conceptual Knowledge“ 1. Emphasize defining features or key characteristics; ask "what makes X, X?" 2. Give examples, non-examples, and “near” examples. 3. Teach concepts in relation to one another; show connections and relationships using visual representations and graphic organizers. 4. Use metaphors and similes. 5. Use “hands-on” activities and manipulatives; build models. Why the Revised Taxonomy? Historical link (1949 to the present) Two dimensions match the structure of all objectives: subject-verb-object. Complete “crossing” of rows with columns makes knowledge and cognitive processes equally important The use of verbs is critical since the verbs represent the cognitive processes that students use on or with the content so that learning occurs
