Bloom’s cognitive taxonomy (1956) is a multilayered model of classifying thinking according to six cognitive levels of learning propounded by Mr.Bloom. It is also referred as a stairway to learning. The concept is aligned with process of ingraining the thinking patterns of a learner. In other words the objective of bloom was to classify the thinking behaviors that were believed to be important in the process of learning.
Bloom’s taxonomy is a classification of learning objectives within education proposed in 1956 by a committee of educators chaired byBenjamin Bloom, who also edited the first volume of the standard text, Taxonomy of educational objectives: the classification of educational goals (1956), although named after Bloom, the publication followed a series of conferences from 1949 to 1953, which were designed to improve communication between educators on the design of curricula and examinations[i].
It was initially segregated into three domains:
· The Cognitive– knowledge based domain
· The Affective- attitudinal based domain
· The Psychomotor– skill based domain which is also known as KSA (knowledge, skills and attitude) or ASK (Attitude, skills and Knowledge)
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, which are listed in order below, starting from the simplest behavior to the most complex. The categories can be thought of as degrees of difficulties. That is, the first ones must normally be mastered before the next ones can take place.
