The Revised Bloom’s Taxonomy (RBT): Improving Curriculum, Instruction, and

Assessment in an Accountability-Driven, Standards-Based World

Developed and Presented by

Dr. Lorin AndersonEdited 2008 by Bill Ellis

A FUNDAMENTAL TRUTHWe don’t see the world as it is; we see

the world through the lens through which we look at it.

Unfortunately, many educators appear to suffer from myopia. They see the trees but not the forest.

Furthermore, they believe that others see the world they way they do. To reinforce this belief they form “tribes” that include those who see things the way they do and exclude others.

The proliferation of tribes has led to a serious problem in education. In Ben Bloom’s words, we have chaos.

Taxonomies provide us with common lenses so we are able to see the world similarly and use common language to share our understanding of the world as we see it. Taxonomies are intended to break down the artificial barriers that exist between and among tribes.

The Taxonomy of Educational Objectives, Handbook 1, The Cognitive Domain, written in the early 1950s and published in 1956, was an initial attempt to produce a common framework in education.

The Common Format of Objectives

Subject Verb Object

S V O

Verb = Create (a product based on)

Subject = The student (will be able to)

Object = The principles & elements of design

The student will be able to create a product based on the principles and elements of design

The SUBJECT is the Learner or the Student.

The student (will)

The student (should)

The student (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.

• Remember

• Understand

• Evaluate

• Create• Evaluation

• Analysis

• Synthesis

• Application

• Comprehension

• Knowledge

Remember

• Retrieve relevant knowledge from long term memory

– Recognizing– Recalling

Understand• Construct meaning from instructional

messages, including oral, written and graphic communication.

– Interpreting– Exemplifying– Classifying– Summarizing– Inferring– Comparing– Explaining

Apply

•  Carry out or use a procedure in a given situation.

– Executing

– Implementing

Analyze• Break material into its constituent parts

and determine how the parts relate to one another and to an overall structure or purpose.

– Differentiating

– Organizing

– Attributing

Evaluate

• Make judgments based on criteria and standards

– Checking

– Critiquing

Create• Put elements together to form a

coherent or functional whole; reorganize elements into a new pattern or structure

– Generating

– Planning

– Producing

Each of the six cognitive process categories was divided into specific cognitive processes. Nineteen (19) specific cognitive processes were identified.

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.

Four Types of Knowledge

• Factual Knowledge

• Conceptual Knowledge

• Procedural Knowledge

• Metacognitive Knowledge

Factual Knowledge• The basic elements

students must know to be acquainted with a discipline or solve problems in it.– Knowledge of

terminology– Knowledge of specific

details and elements

Conceptual Knowledge• The interrelationships among

the basic elements within a larger structure that enable them to function together.

– Knowledge of classifications and categories

– Knowledge of principles and generalizations

– Knowledge of theories, models and structures

Procedural Knowledge• How to do something,

methods of inquiry and criteria for using skills, algorithms, techniques and methods.– Knowledge of subject-specific skills

and algorithms– Knowledge of subject-specific

techniques and methods– Knowledge of criteria for

determining when to use appropriate procedures

Metacognitive Knowledge• Knowledge of cognition in general as well

as awareness and knowledge or one’s own cognition.– Strategic knowledge– Knowledge about cognitive tasks, including

appropriate contextual and conditional knowledge

– Self-knowledgeHow did I get that answer?

Some Examples of Objectives

• The student will be able to recognize the steps of the selling process (C1).[Sports & Entertainment]

• The student will be able to explain foodborne contaminants and food allergies (B2) [Foods II]

More Examples

• The student will be able to demonstrate correct drawing procedures (C3) [Drafting]

• The student will be able to analyze transactions into debit and credit parts(B4) [Computerized Accounting]

Still More Examples

• The student will be able to critique alternative medical modalities (D5) [Medical Sciences II]

• The student will be able to create a product based on the principles and elements of design (B6) [Fundamentals of Technology]

One of the primary values of the Taxonomy Table is that it

helps us understand the intent and meaning of

objectives!

With this understanding we can plan more effective

instruction, design more valid assessments, and increase

the alignment among objectives, assessments, and

instruction are aligned.

How Is This Possible? First, objectives in the same cells of the

taxonomy table are taught in the much the same way

Second, objectives in the same cells of the taxonomy table are assessed in much the same way

Third, using a common framework to examine objectives, instruction, and assessment leads to an increase in the alignment among objectives, assessments, and instruction.
