Bloom's Taxonomy of Educational Objectives

Bloom's Taxonomy of Educational Objectives for
Knowledge-Based Goals1

Level of Expertise Description of Level Example of Measurable Student Outcome
1. Knowledge Recall, or recognition of terms, ideas, procedure, theories, etc. When is the first day of Spring?
2. Comprehension Translate, interpret, extrapolate, but not see full implications or transfer to other situations, closer to literal translation. What does the summer solstice represent?
3. Application Apply abstractions, general principles, or methods to specific concrete situations. What would Earth's seasons be like if its orbit was perfectly circular?
4. Analysis Separation of a complex idea into its constituent parts and an understanding of organization and relationship between the parts. Includes realizing the distinction between hypothesis and fact as well as between relevant and extraneous variables. Why are seasons reversed in the southern hemisphere?
5. Synthesi Creative, mental construction of ideas and concepts from multiple sources to form complex ideas into a new, integrated, and meaningful pattern subject to given constraints. If the longest day of the year is in June, why is the northern hemisphere hottest in August?
6. Evaluation To make a judgment of ideas or methods using external evidence or self-selected criteria substantiated by observations or informed rationalizations. What would be the important variables for predicting seasons on a newly discovered planet?


Bloom's Taxonomy of Educational Objectives for Skills-Based Goals

Level of Expertise Description of Level Example of Measurable Student Outcome
Perception Uses sensory cues to guide actions Some of the colored samples you see will need dilution before you take their spectra. Using only observation, how will you decide which solutions might need to be diluted?
Set Demonstrates a readiness to take action to perform the task or objective Describe how you would go about taking the absorbance spectra of a sample of pigments?
Guided Response Knows steps required to complete the task or objective Determine the density of a group of sample metals with regular and irregular shapes.
Mechanism Performs task or objective in a somewhat confident, proficient, and habitual manner Using the procedure described below, determine the quantity of copper in your unknown ore. Report its mean value and standard deviation.
Complex Overt Response Performs task or objective in a confident, proficient, and habitual manner Use titration to determine the Ka for an unknown weak acid.
Adaptation Performs task or objective as above, but can also modify actions to account for new or problematic situations You are performing titrations on a series of unknown acids and find a variety of problems with the resulting curves, e.g., only 3.0 ml of base is required for one acid while 75.0 ml is required in another. What can you do to get valid data for all the unknown acids?
Organization Creates new tasks or objectives incorporating learned ones Recall your plating and etching experiences with an aluminum substrate. Choose a different metal substrate and design a process to plate, mask, and etch so that a pattern of 4 different metals is created.


Bloom's Taxonomy of Educational Objectives for Affective Goals

Level of Expertise Description of Level Example of Measurable Student Outcome
Receiving Demonstrates a willingness to participate in the activity I'm in class I am attentive to the instructor, take notes, etc. I do not read the newspaper instead.
Responding Shows interest in the objects, phenomena, or activity by seeking it out or pursuing it for pleasure I complete my homework and participate in class discussions.
Valuing Internalizes an appreciation for (values) the objectives, phenomena, or activity I seek out information in popular media related to my class.
Organization Begins to compare different values, and resolves conflicts between them to form an internally consistent system of values Some of the ideas I've learned in my class differ from my previous beliefs. How do I resolve this?
Characterization by a Value or Value Complex Adopts a long-term value system that is "pervasive, consistent, and predictable"> I've decided to take my family on a vacation to visit some of the places I learned about in my class.
