Benjamin S. Bloom was born on 21 February 1913 in Lansford, Pennsylvania, and
died on 13 September 1999. He received a bachelor’s and master’s degree from Pennsylvania State University in 1935 and a Ph.D. in Education from the University of Chicago in March 1942. One of Bloom’s great talents was having a nose for what is significant. His most important initial work focused on what might be called ‘the operationalization of educational
objectives’.Taxonomy of 3 educational objectives: Handbook 1, the cognitive domain (Bloom et al., 1956), a publicationthat has been used throughout the world to assist in the preparation of evaluation materials.
The cognitive taxonomy is predicated on the idea that cognitive operations can be
ordered into six increasingly complex levels. What is taxonomic about the taxonomy is that
each subsequent level depends upon the student’s ability to perform at the level or levels that precede it. For example, the ability to evaluate—the highest level in the cognitive
taxonomy—is predicated on the assumption that for the student to be able to evaluate, he or she would need to have the necessary information, understand the information he or she had, be able to apply it, be able to analyse it, synthesize it and then eventually evaluate it. The taxonomy was no mere classification scheme. It was an effort to hierarchically order cognitive processes.
One of the consequences of the categories in the taxonomy is that they not only serve
as means through which evaluation tasks could be formulated, but also provide a framework for the formulation of the objectives themselves. Bloom was interested in providing a useful practical tool that was congruent with what was understood at that time about the features of the higher mental processes. 1
First of all, I would like to know some important aspects about an important person which I am going to talk about, I love reading, I love biographies and history. A little contribution for a cultural panorama.
