The definition of taxonomy is: 1. the science or technique of classification. 2. a classification into ordered categories: a proposed taxonomy of educational objectives. 3. Biology - the science dealing with the description, identification, naming, and classification of organisms (dictionary.com).
College instructors and K-12 educators use a framework called Bloom’s Taxonomy in their teaching. This framework came about in 1956 published by Benjamin Bloom, Max Englehart, Edward Furst, Walter Hill, and David Krathwohl. This framework consisted of six major categories: Knowledge, Comprehension, Application, Analysis, Synthesis, and Evaluation. The first, Knowledge, was necessary in order to put the other five, which deal with skills and abilities, into practice (Vanderbilt University).
A great description of Bloom’s Taxonomy is that it “is a multi-tiered model of classifying thinking according to six cognitive levels of complexity” (Forehand). It’s also been referred to as a stairway for students to climb. They start with the lower three levels and “climb to a higher level of thought” (Forehand). This movement through the levels has proven helpful with students from kindergarten through graduation.
In 2001, a group of psychologists, theorists, and researchers revised Bloom’s Taxonomy to contain a broader classification, not to be used just for educational purposes. With this new taxonomy, verbs are used to describe categories rather than nouns. These categories require you to Remember, Understand, Apply, Analyze, Evaluate, and Create.
Remembering stands for whether or not the student can recall the information given them. Understanding wants to know if the student can then explain the ideas remembered. When the student can use the information in a “new way”, it is being shown that they are applying it. When the student can “distinguish between the different parts” is means they are analyzing. Evaluating comes into play when the student can justify their analysis. If the student can create a new point of view, they are completing the last level of the taxonomy which is creating (Overbaugh, Schultz).
Bloom stated that “There is more than one type of learning” (Bloom, 1956). The three categories in Bloom’s findings are: Cognitive, which deals with mental skills, Affective, which deals with emotion and growth in feelings, and Psychomotor, which deals with physical and manual skills.
A good reason to use Bloom’s Taxonomy is “objectives”. Both the teachers and the students need to know the reason for the interchange. This helps the teachers know how to plan and design their instruction. When instructors use the taxonomy, they “can create a detailed blueprint of a student-centered learning environment that fosters critical thinking and the process of knowledge construction” (Bloom, 1984).
The categories and classifications can get a bit confusing but I do see their worth. It all does boil down to the “objectives”. If a person knows why they need to know something, it’s much easier to grasp an idea and carry through with each category of the taxonomy. If it is pictured as a ladder, it’s a bit easier to understand. You can’t skip a rung, you have to be steady on the first one and then climb upward one rung at a time until you successfully reach the top.
