Introduction To Revised Bloom's Taxonomy

               Bloom's taxonomy is a way of distinguishing the fundamental questions within the education system. Bloom's taxonomy refers to a classification of the different objectives that educators set for students (learning objectives). It divides educational objectives into three "domains": cognitive, affective, and psychomotor. Within the domains, learning at the higher levels is dependent on having attained prerequisite knowledge and skills at lower levels. A goal of Bloom's taxonomy is to motivate educators to focus on all three domains, creating a more holistic form of education.

The Three Domains of Learning

The committee identified three domains of educational activities or learning (Bloom, et al. 1956):

1. Cognitive: mental skills (knowledge)
2. Affective: growth in feelings or emotional areas (attitude or self)
3. Psychomotor: manual or physical skills (skills)

• 
  

                While the committee produced an elaborate compilation for the cognitive and affective domains, they omitted the psychomotor domain. Their explanation for this oversight was that they have little experience in teaching manual skills within the college level. However, there have been at least three psychomotor models created by other researchers.

                Their compilation divides the three domains into subdivisions, starting from the simplest cognitive process or behavior to the most complex. The divisions outlined are not absolutes and there are other systems or hierarchies that have been devised, such as the Structure of Observed Learning Outcome (SOLO). However, Bloom's taxonomy is easily understood and is probably the most widely applied one in use today.

A.      Cognitive Domain

                The cognitive domain involves knowledge and the development of intellectual skills (Bloom, 1956). This includes the recall or recognition of specific facts, procedural patterns, and concepts that serve in the development of intellectual abilities and skills. There are six major categories of cognitive an processes, starting from the simplest to the most complex:

• ·         Knowledge
• ·         Comprehension
• ·         Application
• ·         Analysis
• ·         Synthesis
• ·         Evaluation

                The categories can be thought of as degrees of difficulties. That is, the first ones must normally be mastered before the next one can take place.

                Lorin Anderson, a former student of Bloom, and David Krathwohl revisited the cognitive domain in the mid-nineties and made some changes, with perhaps the three most prominent ones being (Anderson, Krathwohl, Airasian, Cruikshank, Mayer, Pintrich, Raths, Wittrock, 2000):

• ·         changing the names in the six categories from noun to verb forms
• ·         rearranging them as shown in the chart below
• ·         creating a processes and levels of knowledge matrix

The chart shown below compares the original taxonomy with the revised one:

                This new taxonomy reflects a more active form of thinking and is perhaps more accurate. Now, the one below here is the revised table of cognitive domain:

                Bloom's Revised Taxonomy not only improved the usability of it by using action words, but added a cognitive and knowledge matrix.

                While Bloom's original cognitive taxonomy did mention three levels of knowledge or products that could be processed, they were not discussed very much and remained one-dimensional:

• ·         Factual - The basic elements students must know to be acquainted with a discipline or solve problems.
• ·         Conceptual – The interrelationships among the basic elements within a larger structure that enable them to function together.
• ·         Procedural - How to do something, methods of inquiry, and criteria for using skills, algorithms, techniques, and methods.

                In Krathwohl and Anderson's revised version, the authors combine the cognitive processes with the above three levels of knowledge to form a matrix. In addition, they added another level of knowledge - metacognition:

• ·         Metacognitive – Knowledge of cognition in general, as well as awareness and knowledge of one’s own cognition.

                When the cognitive and knowledge dimensions are arranged in a matrix, as shown below, it makes a nice performance aid for creating performance objectives:

The Cognitive Dimension

The Knowledge Dimension	Remember	Understand	Apply	Analyze	Evaluate	Create
Factual
Conceptual
Procedural
Metacognitive

However, others have identified five contents or artifacts (Clark, Chopeta, 2004; Clark, Mayer, 2007):

• ·         Facts - Specific and unique data or instance.
• ·         Concepts - A class of items, words, or ideas that are known by a common name, includes multiple specific examples, shares common features. There are two types of concepts: concrete and abstract.
• ·         Processes - A flow of events or activities that describe how things work rather than how to do things. There are normally two types: business processes that describe work flows and technical processes that describe how things work in equipment or nature. They may be thought of as the big picture, of how something works.
• ·         Procedures - A series of step-by-step actions and decisions that result in the achievement of a task. There are two types of actions: linear and branched.
• ·         Principles - Guidelines, rules, and parameters that govern. It includes not only what should be done, but also what should not be done. Principles allow one to make predictions and draw implications. Given an effect, one can infer the cause of a phenomena. Principles are the basic building blocks of causal models or theoretical models (theories).

Thus, the new matrix would look similar to this:

The Cognitive Dimension

The Knowledge Dimension	Remember	Understand	Apply	Analyze	Evaluate	Create
Facts
Concepts
Processes
Procedures
Principles
Metacognitive

An example matrix that has been filled in might look something like this:

The Knowledge Dimension	Remember	Understand	Apply	Analyze	Evaluate	Create
Facts	list	paraphrase	classify	outline	rank	categorize
Concepts	recall	explains	demonstrate	contrast	criticize	modify
Processes	outline	estimate	produce	diagram	defend	design
Procedures	reproduce	give an example	relate	identify	critique	plan
Principles	state	converts	solve	differentiates	conclude	revise
Metacognitive	proper use	interpret	discover	infer	predict	actualize

B.      Affective Domain

                The affective domain is one of three domains in Bloom's Taxonomy, with the other two being the cognitive and psychomotor (Bloom, et al., 1956). For an overview of the three domains, see the introduction.

                The affective domain (Krathwohl, Bloom, Masia, 1973) includes the manner in which we deal with things emotionally, such as feelings, values, appreciation, enthusiasms, motivations, and attitudes. The five major categories are listed from the simplest behavior to the most complex:

Category	Example and Key Words (verbs)
Receiving Phenomena: Awareness, willingness to hear, selected attention.	Examples: Listen to others with respect. Listen for and remember the name of newly introduced people. Key Words: acknowledge, asks, attentive, courteous, dutiful, follows, gives, listens, understands
Responds to Phenomena: Active participation on the part of the learners. Attend and react to a particular phenomenon. Learning outcomes may emphasize compliance in responding, willingness to respond, or satisfaction in responding (motivation).	Examples: Participates in class discussions. Gives a presentation. Questions new ideals, concepts, models, etc. in order to fully understand them. Know the safety rules and practice them. Key Words: answers, assists, aids, complies, conforms, discusses, greets, helps, labels, performs, presents, tells
Valuing: The worth or value a person attaches to a particular object, phenomenon, or behavior. This ranges from simple acceptance to the more complex state of commitment. Valuing is based on the internalization of a set of specified values, while clues to these values are expressed in the learner's overt behavior and are often identifiable.	Examples: Demonstrates belief in the democratic process. Is sensitive towards individual and cultural differences (value diversity). Shows the ability to solve problems. Proposes a plan to social improvement and follows through with commitment. Informs management on matters that one feels strongly about. Key Words: appreciates, cherish, treasure, demonstrates, initiates, invites, joins, justifies, proposes, respect, shares
Organization: Organizes values into priorities by contrasting different values, resolving conflicts between them, and creating an unique value system. The emphasis is on comparing, relating, and synthesizing values.	Examples: Recognizes the need for balance between freedom and responsible behavior. Explains the role of systematic planning in solving problems. Accepts professional ethical standards. Creates a life plan in harmony with abilities, interests, and beliefs. Prioritizes time effectively to meet the needs of the organization, family, and self. Key Words: compares, relates, synthesizes
Internalizes Values(characterization): Has a value system that controls their behavior. The behavior is pervasive, consistent, predictable, and most important characteristic of the learner. Instructional objectives are concerned with the student's general patterns of adjustment (personal, social, emotional).	Examples: Shows self-reliance when working independently. Cooperates in group activities (displays teamwork). Uses an objective approach in problem solving. Displays a professional commitment to ethical  practice on a daily basis. Revises judgments and changes behavior in light of new evidence. Values people for what they are, not how they look. Key Words: acts, discriminates, displays, influences, modifies, performs, qualifies, questions, revises, serves, solves, verifies

C.      Psychomotor Domain

                The psychomotor domain (Simpson, 1972) includes physical movement, coordination, and use of the motor-skill areas. Development of these skills requires practice and is measured in terms of speed, precision, distance, procedures, or techniques in execution. Thus, psychomotor skills rage from manual tasks, such as digging a ditch or washing a car, to more complex tasks, such as operating a complex piece of machinery or dancing.

The seven major categories are listed from the simplest behavior to the most complex:

Category	Example and Key Words (verbs)
Perception (awareness): The ability to use sensory cues to guide motor activity.  This ranges from sensory stimulation, through cue selection, to translation.	Examples:  Detects non-verbal communication cues. Estimate where a ball will land after it is thrown and then moving to the correct location to catch the ball. Adjusts heat of stove to correct temperature by smell and taste of food. Adjusts the height of the forks on a forklift by comparing where the forks are in relation to the pallet. Key Words: chooses, describes, detects, differentiates, distinguishes, identifies, isolates, relates, selects.
Set: Readiness to act. It includes mental, physical, and emotional sets. These three sets are dispositions that predetermine a person's response to different situations (sometimes called mindsets).	Examples:  Knows and acts upon a sequence of steps in a manufacturing process. Recognize one's abilities and limitations. Shows desire to learn a new process (motivation). NOTE: This subdivision of Psychomotor is closely related with the “Responding to phenomena” subdivision of the Affective domain. Key Words: begins, displays, explains, moves, proceeds, reacts, shows, states, volunteers.
Guided Response: The early stages in learning a complex skill that includes imitation and trial and error. Adequacy of performance is achieved by practicing.	Examples:  Performs a mathematical equation as demonstrated. Follows instructions to build a model. Responds hand-signals of instructor while learning to operate a forklift. Key Words: copies, traces, follows, react, reproduce, responds
Mechanism (basic proficiency): This is the intermediate stage in learning a complex skill. Learned responses have become habitual and the movements can be performed with some confidence and proficiency.	Examples:  Use a personal computer. Repair a leaking faucet. Drive a car. Key Words: assembles, calibrates, constructs, dismantles, displays, fastens, fixes, grinds, heats, manipulates, measures, mends, mixes, organizes, sketches.
Complex Overt Response (Expert): The skillful performance of motor acts that involve complex movement patterns. Proficiency is indicated by a quick, accurate, and highly coordinated performance, requiring a minimum of energy. This category includes performing without hesitation, and automatic performance. For example, players are often utter sounds of satisfaction or expletives as soon as they hit a tennis ball or throw a football, because they can tell by the feel of the act what the result will produce.	Examples:  Maneuvers a car into a tight parallel parking spot. Operates a computer quickly and accurately. Displays competence while playing the piano. Key Words: assembles, builds, calibrates, constructs, dismantles, displays, fastens, fixes, grinds, heats, manipulates, measures, mends, mixes, organizes, sketches. NOTE: The Key Words are the same as Mechanism, but will have adverbs or adjectives that indicate that the performance is quicker, better, more accurate, etc.
Adaptation: Skills are well developed and the individual can modify movement patterns to fit special requirements.	Examples:  Responds effectively to unexpected experiences.  Modifies instruction to meet the needs of the learners. Perform a task with a machine that it was not originally intended to do (machine is not damaged and there is no danger in performing the new task). Key Words: adapts, alters, changes, rearranges, reorganizes, revises, varies.
Origination: Creating new movement patterns to fit a particular situation or specific problem. Learning outcomes emphasize creativity based upon highly developed skills.	Examples:  Constructs a new theory. Develops a new and comprehensive training programming. Creates a new gymnastic routine. Key Words: arranges, builds, combines, composes, constructs, creates, designs, initiate, makes, originates.

                As mentioned earlier, the committee did not produce a compilation for the psychomotor domain model, but others have. The one discussed above is by Simpson (1972). There are two other popular versions by Dave (1970) and Harrow (1972):

Dave (1975):

Category	Example and Key Words (verbs)
Imitation — Observing and patterning behavior after someone else. Performance may be of low quality.	Examples: Copying a work of art. Performing a skill while observing a demonstrator. Key Words: copy, follow, mimic, repeat, replicate, reproduce, trace
Manipulation — Being able to perform certain actions by memory or following instructions.	Examples: Being able to perform a skill on one's own after taking lessons or reading about it. Follows instructions to build a model. Key Words: act, build, execute, perform
Precision — Refining, becoming more exact. Performing a skill within a high degree of precision	Examples:  Working and reworking something, so it will be “just right.” Perform a skill or task without assistance. Demonstrate a task to a beginner. Key Words: calibrate, demonstrate, master, perfectionism
Articulation — Coordinating and adapting a series of actions to achieve harmony and internal consistency.	Examples: Combining a series of skills to produce a video that involves music, drama, color, sound, etc. Combining a series of skills or activities to meet a novel requirement. Key Words: adapt, constructs, combine, creates, customize, modifies, formulate
Naturalization — Mastering a high level performance until it become second-nature or natural, without needing to think much about it.	Examples:  Maneuvers a car into a tight parallel parking spot. Operates a computer quickly and accurately. Displays competence while playing the piano. Michael Jordan playing basketball or Nancy Lopez hitting a golf ball. Key Words: create, design, develop, invent, manage, naturally

Harrow (1972):

Category	Example and Key Words (verbs)
Reflex Movements — Reactions that are not learned, such as a involuntary reaction	Examples:  instinctive response Key Words: react, respond
