Revised blooms taxonomy

Bloom’s Taxonomy – New Version

In 1956, Benjamin Bloom headed a group of educational psychologists who developed a classification system for levels of cognitive skills and learning behavior. The classification system they created is often referred to as Bloom’s Taxonomy. The word taxonomy means classifications or structures. Bloom’s Taxonomy classifies thinking according to six cognitive levels of complexity

Knowledge
Comprehension
Application
Analysis
Synthesis
Evaluation


The categories are ordered from simple to complex and from concrete to abstract. The classification is often referenced as a progressive climb to a higher level of thinking with the highest level being “evaluation.”


The basic or lowest level in the taxonomy deals with simple knowledge acquisition. At this level, people simply memorize, recall, list, and repeat information. The cognitive complexity grows at every level. At the highest levels, people are able to build a mental structure from diverse elements and are able to put parts together to form a whole, as well as make judgments about the value of ideas

Bloom’s Taxonomy Revised

During the 1990’s, Lorin Anderson and a group of cognitive psychologists updated the taxonomy. The revisions they made appear fairly minor, however, they do have significant impact on how people use the taxonomy. The changes can be divided into three categories: terminology, structure, and emphasis.

Changes to Terminology

The first thing most people recognize is the different terminology. The revised version changes the names of each of the six levels. For example, the lowest level of the original, “knowledge” was renamed and classified as “remembering.” It is also important to note the change from nouns to verbs to describe the different levels of the taxonomy. The names of the major cognitive process categories were changed to indicate action because thinking implies active engagements. Knowledge is an outcome or product of thinking, it is not a form of thinking. Consequently, since the word “knowledge” inaccurately described a category of thinking, it was replaced with the verb “remembering.”

Changes to Structure

The top two levels are essentially swapped from the old to the new version. This revised taxonomy moves the “evaluation” stage down a level and the highest element becomes “creating.” At the second to the highest level of the revised version, people defend, support, justify and evaluate their opinion on this information. And at the highest level, people generate new ideas, create a new product, or construct a new point of view. This change was made because the taxonomy is viewed as a hierarchy reflecting increasing complexity of thinking, and creative thinking (creating level) is considered a more complex form of thinking than critical thinking (evaluating level). A person can evaluate information without being creative, but creative thinking requires some level of evaluation or critical thinking (i.e. you need to evaluate the effectiveness of your new idea).

Changes in Emphasis

The revision emphasizes the use of taxonomy as a tool for alignment of curriculum planning, instructional delivery, and assessment. Additionally, the revision is aimed at a broader audience. The original taxonomy was viewed as a tool best applied in the younger grades at school. The revised version is more universal and easily applicable at elementary, secondary, as well as adult training.


The new terms are defined as:

Levels Description
Remembering Retrieving, recognizing, and recalling relevant knowledge from long-term memory. This level is simply remembering or recalling previous learned information.
Understanding Constructing meaning from oral, written, and graphic messages through interpreting, exemplifying, classifying, summarizing, inferring, comparing, and explaining.   This is essentially demonstrating understanding of information by explaining ideas or concepts.
Applying Carrying out or using a procedure through executing, or implementing. Basically, this is using the information in another familiar situation.
Analyzing Breaking material into constituent parts, determining how the parts relate to one another and to an overall structure or purpose through differentiating, organizing, and attributing.
Evaluating Making judgments based on criteria and standards through checking and critiquing. This includes justifying a decision or course of action.
Creating Putting elements together to form a coherent or functional whole; reorganizing elements into a new pattern or structure through generating, planning, or producing. This includes generating new ideas, products, or ways of viewing things.

Applying the Revised Version of Bloom’s Taxonomy

Just like the original taxonomy, the revised version provides a valuable framework for teachers, trainers, and instructional designers to use to focus on higher order thinking. By providing a hierarchy of thinking, both version can help in developing performance tasks, creating questions, or constructing problems.
