Benjamin Bloom and his Taxonomy
Benjamin Bloom is recognised as the the leader in the pursuit of defining educational objectives early this century. Developing a classification system (a taxonomy) of educational objectives, Bloom divided his findings into three domains;
Bloom listed six basic objectives within the COGNITIVE domain:
1. Knowledge – remembering or recognising something previously encountered without necessarily understanding, using, or changing it.
2. Comprehension – understanding the material being communicated without necessarily relating it to anything else.
3. Application – using general concept to solve a particular problem.
4. Analysis – breaking something down into parts.
5. Synthesis – creating something new by combining different ideas.
6. Evaluation – judging the value of materials or methods as they might be applied in a particular situation.
Bloom listed five basic objectives in the AFFECTIVE domain:
1. Receiving – being aware of or attending to something in the environment.
2. Responding – showing some new behaviour as a result of experience.
3. Valuing – showing some definite involvement or commitment.
4. Organisation – integrating a new value into one’s general set of values, giving it some ranking among one’s general priorities.
5. Characterisation by value – acting consistently with the new value.
Bloom listed six basic objectives in the PSYCHOMOTOR domain:
1. Reflex movements – actions that occur involuntarily in response to some stimulus.
2. Basic fundamental movements – innate movement patterns formed from a combination of reflex movements.
3. Perceptual abilities – translation of stimuli received through the senses into appropriate movements.
4. Physical abilities – basic movements and abilities that are essential to the development of more highly skilled movements.
5. Skilled movements – more complex movements requiring a certain degree of efficiency.
6. Non-discursive movements – ability to communicate through body movement.
The above information is taken solely from
Woolfolk, A.E. Educational Psychology Fourth Edition
(New Jersey, USA: Prentice Hall, 1990)
The following is an example of how Bloom’s Taxonomy may be implemented into a working curriculum unit
– (in this instance a “Science” unit)
Taken from Joseph, J. and Brown, K Authentic Assessment Workshop 1998
Theme – Ecology Systems (Ecosystems)
Knowledge – define, identify, list, locate, recall
Simple – What is an ecosystem?
Extended – Define an ecosystem and list the varieties that are found in South Australia.
Comprehension – compare, summarise, explain, convert
Simple – List the different parts of the ecosystem and explain what they do.
Extended – Compare a marine ecosystem with one from another area of our state.
Application – apply, calculate, practice, demonstrate
Simple – using a diagram, show how the water cycle operates in an ecosystem.
Extended – Demonstrate what happens when humans interfere with the water cycle.
Analysis – analyse, contrast, deduce, differentiate, distinguish, infer
Simple – Contrast the natural water cycle with that used by our community
Extended – Examine an ecosystem that has been damaged by human interference. Avoided how?
Synthesis – compose, create, design, formulate, produce, rearrange
Simple – Identify an unspoilt ecosystem and design a way of preserving it.
Extended – How would preserving our local ecosystems enhance our environment?
Evaluation – appraise, assess, critique, judge, support
Simple – It it reasonable that people pollute our water
ways? Defend your answer.
Extended – Assess the impact of pollution in our local waterways.
Relating Bloom’s Taxonomy to Special Needs
Using the six levels of Bloom’s Taxonomy to plan questions and activities provides the scope for student negotiation and the opportunity to differentiate the curriculum for some students in accordance with their interests, abilities and specific learning needs.
Applying Bloom’s Taxonomy is a WHOLE class exercise and is inclusive of both mainstream and special need children.
Teachers choosing to use the taxonomy in this way may structure learning experiences so that :-
* All students work through the Knowledge and Comprehension stage, then select one activity from each of the other levels
* All students work through the Knowledge and Comprehension stage and then select activities from any other levels
* Some work through the knowledge and comprehension stage and others work at higher levels. (This is particularly relevant for Gifted and Talented children).
* All students work from any level
* Some activities are tagged as essential – some as optional
* Select a thinking process as a focus – e.g. Analysis (where instruction is being provided in that process)
* Some work through Knowledge and Comprehension stage, then write down their own activity at their own preferred level
* Students write their own activity/questions from the taxonomy. (Engaging the students in this activity serves as a useful lead-in to the negotiated student project to follow.)
Teaching using Bloom’s Taxonomy
1.Knowledge (finding out)
a. Use- records, films, videos, models, events, media, diagrams, books…
b. observed behaviour- ask match, discover, locate, observe, listen.
2. Comprehension (understanding)
a. Use- trends, consequences, tables, cartoons….
b. observed behaviour- chart, associate, contrast, interpret, compare.
3. Application (making use of the knowledge)
a. use- collection, diary, photographs, sculpture, stitchery, illustration.
b. observed behaviour- list, construct, teach, paint, manipulate, report.
4. Analysis questions (taking apart the known)
a. use- graph, survey, diagram, chart, questionnaire, report….
b. observed behaviour- classify, categorise, dissect, advertise, survey.
5. Synthesis (putting things together in another way)
a. use- article, radio show, video, puppet show, inventions, poetry, short story…
b. observed behaviour- combine, invent, compose, hypothesis, create, produce, write.
6. Evaluation (judging outcomes)
a. use- letters, group with discussion panel, court trial, survey, self-evaluation, value, allusions…
b. observed behaviour- judge, debate, evaluating, editorialise, recommend
Bloom in Practice
Below is an example of how Bloom’s Taxonomy can be used in the classroom.
I will actually be using this myself during my final practicum and each section of Bloom’s taxonomy will be listed on a separate poster, displayed in the classroom, that will detail the two learning foci, namely – Food Advertising and Nutrition
This is part of an eight-week unit in the key learning of the Arts, that will focus mainly on the Media influence on our eating and dietary habit
Students will be choosing activities from the posters as part of a point system they need to fulfil in this unit.
The low-order thinking tasks, (that is, Knowledge, Comprehension, and Application) will earn 1, 2 and 3 points respectively, while the high-order thinking tasks will earn 5 for Analysis and Evaluation and 6 for Synthesis.
(It is quite possible to use a different combination of points, depending on the task difficulty assigned)
(Factual answers, Recall and Recognition)

Describe what the advertisers use in the Hungry Jacks advertisement to sell their products.

Write a one page example of how you would teach about the new food guide. Include your resources.
What would you ask shoppers in a supermarket if you were doing a survey of what food they eat? (10 questions)
(Break into parts to examine more closely)
