Bloom's Taxonomy


      Bloom's Taxonomy

 What is Taxonomy?

                         Taxonomy means 'a set of classification principles', or 'structure', and Domain simply means 'category'. Taxonomy -- from Greek taxis, meaning arrangement or division, and nomos, meaning law -- is the science of classification according to a predetermined system.

 Bloom's Taxonomy:

                     In 1956, Benjamin Bloom headed a group of educational psychologists who developed a classification of levels of intellectual behavior important in learning. Bloom's Taxonomy divides educational objectives into learning domains, with the understanding that higher levels of learning are dependent on having attained prerequisite knowledge and skills at lower levels.
THE THREE DOMAINS OF LEARNING:
The committee identified three domains of educational activities or learning (Bloom, et al. 1956):
v  Cognitive domain (intellectual capability, ie., knowledge, or 'think')
v  Affective domain (feelings, emotions and behaviour, ie., attitude, or 'feel')
v  Psychomotor domain (manual and physical skills, ie., skills, or 'do')

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:-


1.knowledge:
A.knowledge of specifics
·          knowledge of terminology
·          knowledge of specific facts
B. knowledge of ways and means of dealing with specifics
·         knowledge of conventions
·         knowledge of trends and sequences
·         knowledge of classification and categories
·         knowledge of criteria
·         knowledge of methodology
C. knowledge of universal and abstractions in a field
·         knowledge of principles and generalisations
·         knowledge of theoriws and structures

2.Comprehension:

A.Translation
B.Interpretation
C.Explanation

3.Application

4.Analysis:

A.Analysis of elements
B. Analysis of relationships
C. Analysis of organisational principles

5.Synthesis:

A.    Production of unique communication
B.     Production of a plan
C.     Derivation of a set of abstract relations

6.Evaluation:

A.    Judgement in terms of internal evidence
B.     Judgement in terms of external criteria

EXPLANATIONS:

1.KNOWLEDGE:
                             It is is defined as remembering of previously learned material. This may involve the recall of a wide range of material, from specific facts to complete theories, but all that is required is the bringing to mind of the appropriate information. Knowledge represents the lowest level of learning outcomes in the cognitive domain.
  • Represents the lowest level of knowledge
  • Imparts knowledge that needs to be recalled or recognized
  • Learners are assessed on their ability to recall or recognize facts

Verbs: arrange, define, duplicate, label, list, memorize, name, order, recognize, relate, recall, repeat, reproduce state.

2,COMPREHENSION:
                      It is defined as the ability to grasp the meaning of material. This may be shown by translating material from one form to another (words to numbers), by interpreting material (explaining or summarizing), and by estimating furture trends (predicting consequences or effects). These learning outcomes go one step beyond the simple remembering of material, and represent the lowest level of understanding.

·         Imparts knowledge that needs to be assimilated in order to interpret / make a decision
·         Assumes recall of facts (Level 1) has been mastered
·         Learners are assessed on comprehension and the resulting ability to make a decision in a given situation
Verbs: classify, describe, discuss, explain, express, identify, indicate, locate, recognize, report, restate, review, select, translate.

 Application :
             It refers to the ability to use learned material in new and concrete situations. This may include the application of such things as rules, methods, concepts, principles, laws, and theories. Learning outcomes in this area require a higher level of understanding than those under comprehension.
  • Used to teach skills for application in various circumstances
  • Assumes recall of facts (Level 1) and assimilation have been mastered (Level 2)
  • Learners are assessed on their ability to apply a skill in a new situation

Verbs: apply, choose, demonstrate, dramatize, employ, illustrate, interpret, operate, practice, schedule, sketch, solve, use, write.

Analysis:
                        It refers to the ability to break down material into its component parts so that its organizational structure may be understood. This may include the identification of the parts, analysis of the relationships between parts, and recognition of the organizational principles involved. Learning outcomes here represent a higher intellectual level than comprehension and application becasue they require an understanding of both the content and the structural form of the material.
·         Used to teach analysis of a situation to arrive at a decision/compare/differentiate
·         Assumes recall of facts, assimilation, and application (Level 3) have been mastered
·         Learners are assessed on their ability to analyze, compare, differentiate, or justify

Verbs: analyze, appraise, calculate, categorize, compare, contrast, criticize, differentiate, discriminate, distinguish, examine, experiment, question, test.

Synthesis :
                                It refers to the ability to put parts together to form a new whole. This may involve the production of a unique communication (theme or speech), a plan of operations (research proposal), or a set of abstract relations (scheme for classifying information). Learning outcomes in this area stress creative behaviors, with major emphasis on the formulation of new patterns or structures.
·         Used to teach how to create new entities from known information/objects/facts
·         Assumes mastery of all previous cognitive levels
·         Learners are assessed on their ability to combine, summarize, organize
Verbs: arrange, assemble, collect, compose, construct, create, design, develop, formulate, manage, organize, plan, prepare, propose, set up, write.

Evaluation:
                  It is concerned with the ability to judge the value of material (statement, novel, poem, research report) for a given purpose. The judgements are to be based on definite criteria. These may be internal criteria (organization) or external criteria (relevance to the purpose) and the student may determine the criteria or be given them. Learning outcomes in this area are highest in the cognitive hierarchy because they contain elements of all the other categories, plus conscious value judgements based on clearly defined criteria.
·         Used to teach knowledge that will enable learners to make judgments
·         Considers all previous levels of knowledge
·         Learners are assessed on their ability to evaluate new entities
Verbs: appraise, argue, assess, attach, choose compare, defend estimate, judge, predict, rate, core, select, support, value, evaluate
.
 Affective Domain:

                             The affective domain includes the manner in which we deal with things emotionally,such as feelings,values,appreciation,enthusism,motivations and attitudes.

                                              Taxonomy of objectives in the affective domain proposed  by Krathwohl,Bloom &Maria(1964),is presented:-

1.      Receiving(attending):
a)      Awareness
b)      Willingness to receive
c)      Controlled or selected attention
     2.Responding:
a)      Acquiesence in responding
b)      Wiilingness to repond
c)      Satisfaction in reponse
    3.Valuing:
a)      Acceptance of a value
b)      Preference for a value
c)      Commitment
  4.Organisation:
a)      Conceptualization of a value
b)      Organisation of a value system
5.Characterization by a value:
a)      Generalised chat
b)      Characterization

This can be diagramatically presented as:-  
         




                   

EXPLANATION:

 

Receiving

                              Receiving is the lowest level of the affective domain. It is simply the awareness of feelings and emotions. It involves passively paying attention and being aware of the existence of certain ideas, material, or phenomena. Without this level, no learning can occur. If information is never received and cannot be remembered.

Examples: Listening attentively to someone, watching a movie, listening to a lecture, watching waves crash on the sand.

 Verbs: Accept,Attend,Develop,Recognize.Notice,Look,Share

 

Responding

                                   This level involves actively participating in the learning process. You are not only aware of a stimulus, but you react or respond to it in some way.

Examples: Having a conversation, participating in a group discussion, giving a presentation, complying with procedures, or following directions.

 Verbs: Complete,Comply,Cooperate,Discuss,Examine,Obey,Respond

 

Valuing

                                        Valuing is the ability to see the worth of something and express it. Valuing is concerned with the worth you attach to a particular object, phenomenon, behavior, or piece of information.This level ranges from simple acceptance to the more complex state of commitment.

Examples: Proposing a plan to improve team skills, supporting ideas to increase proficiency, or informing leaders of possible issues.

Verbs: Accept, Defend ,Devote, Pursue, Seek,Argue,Display

 Organisation:
                                  Organizing involves putting together different values, information, and ideas then relating them to already held beliefs to bring it into an internally consistent philosophy. Essentially, it is ability to prioritize one value over another and create a unique value system. The focus of this level is on comparing, relating, and assessing values to create that unique value system.

Examples: Spending more time studying then playing sports, recognizing the need for balance between work and family, or prioritizing time effectively to meet goals.

Verbs: Codify ,Discriminate,Display,Order,Organize,Systematize,Weigh

 Characterizing
                        This is the highest of the affective domain. It is about internalizing values. It means acting consistently in accordance with the set of values you have internalized and your characterization or philosophy about life. Essentially, you internalize values and let them control or guide your behavior.

Examples: You spend time with your family, you reframe from using profanity, and you make friends based on personally and not looks.

 

Verbs: Internalize,Verify,Disply,Internalize,Resolve

                                   

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.

Taxonomy of objectives in the psychomotor domain:
                                     It was Simpson(Simpson,1966) who first presented the classification of objectives in the psychomotor domain.Later it got modified by Harrow(1972) as:-

Reflex movements
                     Objectives at this level include reflexes that involve one segmental or reflexes of the spine and movements that may involve more than one segmented portion of the spine as intersegmental reflexes (e.g., involuntary muscle contraction). These movements are involuntary being either present at birth or emerging through maturation.

Baic fundamental movements
                       Objectives in this area refer to skills or movements or behaviors related to walking, running, jumping, pushing, pulling and manipulating. They are often components for more complex actions.

Perceptual abilities
                        Objectives in this area should address skills related to kinesthetic (bodily movements), visual, auditory, tactile (touch), or coordination abilities as they are related to the ability to take in information from the environment and react.


Physical abilities
                     Objectives in this area should be related to endurance, flexibility, agility, strength, reaction-response time or dexterity.

Skilled movements
                     Objectives in this area refer to skills and movements that must be learned for games, sports, dances, performances, or for the arts.

Nondiscursive communication
                    Objectives in this area refer to expressive movements through posture, gestures, facial expressions, and/or creative movements like those in mime or ballet.  These movements refer to interpretative movements that communicate meaning without the aid of verbal commands or help.

 Taxonomy of Psychomotor Objectives:
1.Imitation:
a)      Impulsion
b)      Overt repition
2.Manipulation:
a)      Following direction
b)      Selection
c)      Fixation
3.Precision:
a)      Reproduction
b)      Control
4.Articulation:
a)      Sequence
b)      Harmony
5.Naturalization:
a)      Automatization
b)      Interiorization
                                                 



Explanation:

1.    IMITATION:
                         Imitation is the lowest level of the objectives in the psychomotor domain. When the student is exposed to an observable action, he begins to make a covert imitation of the action. Imitation begins with inner rehearsal of the muscular system guided an inner push or an impulse to imitate action. Such covert behaviour appears to be the starting point in the growth of psychomotor skill.

Verbs: copy, follow, replicate, repeat, adhere

2.      MANIPULATION:

                          At this level, the student should be capable of performing an act according to instructions rather than just on basis of observation as in the case at the level of imitation. He begins to attain skill in manipulating chosen elements with sufficient practice of selected action. At the level of performance is fairly well set.

Verbs: re-create, build, perform, execute, implement

3.      PRECISION:

                          At the level of precision, the proficiency of performance reaches a higher level of reinforcement in reproducing of performance reaches a higher level of reinforcement in reproducing a given act. The student does not need a model to reproduce or to guide his/her action. He is able to increase or decrease the speed of the action and introduce several variations according to specific requirements of different situations.

Verbs: demonstrate, complete, show, perfect, calibrate, control,

4.      ARTICULATION:

                       This category behaviour emphasizes the coordination of a series of acts by establishing an appropriate sequence and accomplishing harmony or internal consistency among different acts The student becomes able to perform them in a harmonious manner with appropriate articulation in terms of time, speed and other relevant variables. He develops proficiency a number of related acts simultaneously and sequentially and thereby can produce the desired effect.

Verbs: construct, solve, combine, coordinate, integrate, adapt, develop, formulate, modify, master

5.NATURALISATION:

                    This is the highest level of behaviour in the psychomotor domain. This category refers to naturalization of the single act or a series of articulated acts. At this stage, the skill of performance attained its highest level of proficiency and the act is performed with the least expenditure of psychic energy. The student does not even know that the act is being performed, until he is obstructed or severely disturbed. In other words, the habit of performance becomes his second nature.

Verbs: design, specify, manage, invent, project-manage
