Bloom's Taxonomy was created in 1956 under the leadership of educational psychologist Dr. Benjamin Bloom in order to promote higher forms of thinking in education, such as analyzing and evaluating concepts, processes, procedures, and principles, rather than just remembering facts (rote learning). It is most often used when designing lesson objectives, learning goals, and instructional activities. Bloom et al. (1956) identified three domains of educational activities or learning:
Since the work was produced by higher education, the words tend to be a little bigger than what would be normally used. Domains may be thought of as categories. Instructional designers, trainers, and educators often refer to these three categories as KSA (Knowledge [cognitive], Skills [psychomotor], and Attitudes [affective]). This taxonomy of learning behaviors may be thought of as “the goals of the learning process.” That is, after a learning episode, the learner should have acquired a new skill, knowledge, and/or attitude.
While Bloom et al. (1956) 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.
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 levels of cognitive processes, starting from the simplest to the most complex. The levels can be thought of as degrees of difficulties. That is, the first ones must normally be mastered before the next one can take place.

This new taxonomy reflects a more active form of thinking and is perhaps more accurate. The new version of Bloom's Taxonomy with examples and keywords is shown in Figure 10.3.

Cognitive Processes and Levels of Knowledge Matrix
Bloom's Revised Taxonomy not only improved the usability of it by using action words, but added a Cognitive Process Dimension and Knowledge Dimension Matrix (Figure 10.4). 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:
In Krathwohl and Anderson's (2001) 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:
When the cognitive and knowledge dimensions are arranged in a matrix, as shown below, it makes a nice performance aid for creating performance objectives (Figure 10.4).

The psychomotor domain (Simpson, 1972) (Figure 10.7) 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.
Figure 10.7 Levels of Psychomotor Domain
The seven major levels (Figure 10.8) are listed from the simplest behavior to the most complex (Simpson, 1972):
Figure 10.8 Levels of Psychomotor Domain with Examples and Key Words by Simpson (1972)
Levels |
Examples 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: Detect 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. Adjust heat of stove to correct temperature by smell and taste of food. Adjust 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: Know and act upon a sequence of steps in a manufacturing process. Recognize one's abilities and limitations. Show 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 include imitation, trial, and error. Adequacy of performance is achieved by practicing. |
Examples: Perform a mathematical equation as demonstrated. Follow instructions to build a model. Respond hand-signals of instructor while learning to operate a forklift. Key Words: copies, traces, follows, reacts, reproduces, 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 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: Maneuver a car into a tight parallel parking spot. Operate a computer quickly and accurately. Display 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: Respond effectively to unexpected experiences. Modify instruction to meet the needs of the learners. Perform a task with a machine, which 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: The creating of new movement patterns to fit a particular situation or specific problem. Learning outcomes emphasize creativity based upon highly developed skills. |
Examples: Construct a new theory. Develop a new and comprehensive training programming. Create a new gymnastic routine. Key Words: arranges, builds, combines, composes, constructs, creates, designs, initiate, makes, originates |
Bloom et al. (1956) did not produce a compilation for the psychomotor domain model, but others have. The one discussed above is by Simpson (1972) (Figure 10.8). There are two other popular versions by Dave (1970) (Figure 10.9) and Harrow (1972) (Figure 10.10):
Figure 10.9 Levels of Psychomotor Domain with Examples and Key Words by Dave (1970)

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. Following 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.” Performing a skill or task without assistance. Demonstrating a task to a beginner. Key Words: calibrate, demonstrate, master, perfection |
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 of performance until it become second-nature or natural, without needing to think much about it. |
Examples: Maneuvering a car into a tight parallel parking spot. Operating a computer quickly and accurately. Displaying competence while playing the piano. Michael Jordan playing basketball or Nancy Lopez hitting a golf ball. Key Words: create, design, develop, invent, manage, naturally |

Non-discursive Communication: Effective use body language, such as gestures and facial expressions. |
Examples: Expressing one's self by using movements and gestures Key Words: arrange, compose, interpretation |
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). 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 levels are listed from the simplest behavior to the most complex (Figure 10.11 & Figure 10.12):
Figure 10.11 Levels of Affective Domain
Figure 10.12 Levels of Affective Domain with Examples and Key Words
Levels |
Examples 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: acknowledges, asks, follows, gives, listens, understands |
Responding 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: Participate in class discussions. Give a presentation. Question 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: Demonstrate belief in the democratic process. Is sensitive towards individual and cultural differences (value diversity). Show the ability to solve problems. Propose a plan to social improvement and follows through with commitment. Inform management on matters that one feels strongly about. Key Words: appreciates, cherishes, treasures, demonstrates, initiates, invites, joins, justifies, proposes, respects, shares |
Organizing: The organizing of values into priorities by contrasting different values, resolving conflicts between them, and creating a unique value system. The emphasis is on comparing, relating, and synthesizing values. |
Examples: Recognize the need for balance between freedom and responsible behavior. Explain the role of systematic planning in solving problems. Accept professional ethical standards. Create a life plan in harmony with abilities, interests, and beliefs. Prioritize time effectively to meet the needs of the organization, family, and self. Key Words: compares, relates, synthesizes |
Internalizing Values (characterization): Having 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: Show self-reliance when working independently. Cooperate in group activities (display teamwork). Use an objective approach in problem solving. Display a professional commitment to ethical practice on a daily basis. Revise judgments and change behavior in light of new evidence. Value people for what they are, not how they look. Key Words: acts, discriminates, displays, influences, modifies, performs, qualifies, questions, revises, serves, solves, verifies |
Educational Implications (Clark, 2015d)
Learning or instructional strategies determine the approach for achieving the learning objectives and are included in the pre-instructional activities, information presentation, learner activities, testing, and follow-through. The strategies are usually tied to the needs and interests of students to enhance learning and are based on many types of learning styles (Ekwensi, Moranski, &Townsend-Sweet, 2006). Thus the learning objectives point you towards the instructional strategies, while the instructional strategies will point you to the medium that will deliver or assist the delivery of the instruction, such as elearning, self-study, classroom learning and instructional activities, etc.
The Instructional Strategy Selection Chart (Figure 10.13) shown below is a general guideline for selecting the teaching and learning strategy. It is based on Bloom's Taxonomy (Learning Domains). The matrix generally runs from the passive learning methods (top rows) to the more active participation methods (bottom rows). Bloom's Taxonomy (the right three columns) runs from top to bottom, with the lower level behaviors being on top and the higher behaviors being on the bottom. That is, there is a direct correlation in learning:

Figure 10.13. The chart above does not cover all possibilities, but most activities should fit in. For example, self-study could fall under reading, audio visual, and/or activities, depending upon the type of learning environment and activities teachers design.
Criticisms of Bloom’s Taxonomy
As Morshead (1965) pointed out on the publication of the second volume, the classification was not a properly constructed taxonomy, as it lacked a systemic rationale of construction. This was subsequently acknowledged in the discussion of the original taxonomy in its 2000 revision (Anderson & Krathwohl, 2001), and the taxonomy was reestablished on more systematic lines. It is generally considered that the role the taxonomy played in systematizing a field was more important than any perceived lack of rigor in its construction.
Some critiques of the taxonomy's cognitive domain admit the existence of six categories of cognitive domain but question the existence of a sequential, hierarchical link (Paul, 1993). Often, educators view the taxonomy as a hierarchy and may mistakenly dismiss the lowest levels as unworthy of teaching (Flannery, 2007; Lawler, 2016). The learning of the lower levels enables the building of skills in the higher levels of the taxonomy, and in some fields, the most important skills are in the lower levels, such as identification of species of plants and animals in the field of natural history (Flannery, 2007; Lawler, 2016). Instructional scaffolding of higher-level skills from lower-level skills is an application of Vygotskian constructivism (Keene, Colvin, & Sissons, 2010; Vygotsky, 1978).
Some consider the three lowest levels as hierarchically ordered, but the three higher levels as parallel (Anderson & Krathwohl, 2001). Others say that it is sometimes better to move to Application before introducing concepts (Tomei, 2010, p.66). The idea is to create a learning environment where the real world context comes first and the theory second to promote the student's grasp of the phenomenon, concept or event. This thinking would seem to relate to the method of problem-based learning.
Furthermore, the distinction between the categories can be seen as artificial since any given cognitive task may entail a number of processes. It could even be argued that any attempt to nicely categorize cognitive processes into clean, cut-and-dried classifications undermines the holistic, highly connective and interrelated nature of cognition (Fadul, 2009). This is a criticism that can be directed at taxonomies of mental processes in general.
