Week:3- Blooms' Taxonomy
* Blooms
Taxonomy:
Blooms’Taxonomy is ‘a classification of learning objectives’ within education proposed in 1956 by a committee of education by
Benjamin Bloom. It means of expressing qualitatively different kinds of
thinking. Who also edited the first volume of the standard text, Taxonomy of
educational objectives: the classification of educational goals. It refers to a
classification of the different objectives that educators set for students
learning objectives.
Blooms’ Taxonomy divides educational objectives into
three “domains”:
1) Cognitive,
2) Affective, 3) Psychomotor.
Sometimes
loosely described as knowing/head, feeling/heart and doing/heads.A goal of
Blooms’ Taxonomy is to motivate educators to focus on all three domains,
creating a more holistic form of education. ‘’Taxonomy ‘simply means
“classification”, so the well known taxonomy of learning objectives is an
attempt to classify forms and levels of learning. It identifies three “domains”
of learning, each of which is organized as a series of level or pre-requisites.
It is suggested that one can’t effectively- or ought not to try to- address
higher levels until those below them have been covered. Thus in the Cognitive
domain, training for technicians may cover knowledge, comprehension and
application, but not concern itself with analysis and above, whereas full professional training may be expected to
include this and synthesis and evaluation as well.
· * Cognitive:
The most used of the domains, refers to knowledge
structures. It can be viewed as a sequence of progressive contextualization of
the material. (Based on Bloom, 1956).

(Anderson and Krathwohl, 2001) (Revised taxonomy of the
cognitive domain following
(Significant modification) Anderson and Krathwohl, 2001)
Skills in the cognitive domain revolve around
knowledge, comprehension, Application, Analysis, Synthesis, and Evaluation.

* Criticism of the Taxonomy:
As Morshead pointed out on the publication of the
second volume, the classification wasn’t a properly constructed taxonomy, as it
lacked a systematic rationale of construction. This was subsequent acknowledge
in the discussion of the original taxonomy by Krathwohl in the revision of the
taxonomy and the taxonomy reestablished on more systematic lines. It is
generally considered that the taxonomy played in systematizing a field was more
important than any perceived lack of rigor in its construction.
Some critiques of Blooms Taxonomy admit the
existence of these six categories, but question the existence of a sequential,
hierarchical link. Also the revised edition of Blooms Taxonomy has moved
Synthesis in higher order than Evaluation. Some consider the three lowest
levels as hierarchically ordered, but the three higher levels as parallel.
There say that it is sometimes better to move to Application before introducing
concepts. This thinking would seem to relate to the method of Problem based
learning.

Taxonomy of Educational Objectives:-
At the
present time it is sufficient to state that instructional objectives are
concrete statements of the goals toward which instruction is directed. They
play an important role in the process of learning and instruction.
When developing instructional objectives, providing
instruction, and evaluating student performance, it is important to keep in
mind that there are different levels or outcomes of learning. Distinguishing
among different levels and outcomes of learning is important. If teachers are
unaware of different levels of learning, they are likely to focus on one level
to the detriment of others. For example, a teacher may teach a vast amount of
factual information but never get around to teaching students to apply and
synthesize this information. Or a teacher may teach higher level thinking
skills without realizing that these skills require the prior learning of basic
skills that must be integrated into these higher order skills.
In addition, it is not unusual to see
a teacher who wants her students to learn higher order thinking skills give
examinations that require only lower level skills. Under such circumstances, the
students are likely to put their efforts into the lower order skills. Skills at
different levels must be taught (and tested) in different ways; and therefore
it is important for teachers and other instructional designers to take into
account the different levels and outcomes of instruction.
Bloom's (1956) Taxonomy of
Educational Objectives is the most renowned description of the levels
of cognitive performance. The levels of the Taxonomy and
examples of activities at each level are given in Table 3.3. The levels of this
taxonomy are considered to be hierarchical. That is, learners must master lower
level objectives first before they can build on them to reach higher level
objectives.
· * Bloom's
Taxonomy of Educational Objectives:-
1.
Knowledge (Remembering previously learned material)
Educational
Psychology: Give the definition of punishment.
Mathematics:
State the formula for the area of a circle.
English
/ Language Arts: Recite a poem.
2.
Comprehension (Grasping the meaning of material)
Educational
Psychology: Paraphrase in your own words the definition of punishment; answer
questions about the meaning of punishment.
Mathematics:
Given the mathematical formula for the area of a circle, paraphrase it using
your own words.
English
/ Language Arts: Explain what a poem means.
3.
Application (Using information in concrete situations)
Educational
Psychology: Given an anecdote describing a teaching situation, identify
examples of punishment.
Mathematics:
Compute the area of actual circles.
English
/ Language Arts: Identify examples of metaphors in a poem.
4.
Analysis (Breaking down material into parts)
Educational
Psychology: Given an anecdote describing a teaching situation, identify the psychological
strategies intentionally or accidentally employed.
Mathematics:
Given a math word problem, determine the strategies that would be necessary to
solve it.
English
/ Language Arts: Given a poem, identify the specific poetic strategies employed
in it.
5.
Synthesis (Putting parts together into a whole)
Educational
Psychology: Apply the strategies learned in educational psychology in an
organized manner to solve an educational problem.
Mathematics:
Apply and integrate several different strategies to solve a mathematical
problem.
English
/ Language Arts: Write an essay or a poem.
6.
Evaluation (Judging the value of a product for a given purpose, using definite
criteria)
Educational
Psychology: Observe another teacher (or yourself) and determine the quality of
the teaching performance in terms of the teacher's appropriate application of
principles of educational psychology.
Mathematics:
When you have finished solving a problem (or when a peer has done so) determine
the degree to which that problem was solved as efficiently as possible.
English
/ Language Arts: Analyze your own or a peer's essay in terms of the principles
of composition discussed during the semester.
*Concusion:-
Bloom's
Taxonomy need not be applied exclusively after course goals have been defined. Indeed,
Bloom's Taxonomy and the words associated with its different categories can
help in the goals-defining process itself. Thus, Bloom's Taxonomy can be used
in an iterative fashion to first state and then refine course goals. Bloom's
Taxonomy can finally be used to identify which classroom assessment techniques
are most appropriate for measuring these goals.
