Editor's Notes
HISTORY – The Original Bloom’s Taxonomy Taxonomy of Cognitive Objectives: Handbook I, The Cognitive Domain 1950s - developed by Benjamin Bloom and fellow university examiners (about 50 people) The name “Bloom’s Taxonomy” came from the senior editor -- being Benjamin Bloom Means of expressing qualitatively different kinds of intellectual skills and abilities Was adapted for classroom use as a planning tool Provides a way to organize thinking skills into six levels, from the most basic to the more complex levels of thinking Was hypothesized to be a cumulative hierarchy; that is, each lower level was believed necessary to move to the next level
Changes were based on 50+ years of history of using original Taxonomy and research on learning conducted by cognitive psychologists There are eight authors of the revised Taxonomy; the two editors were Lorin Anderson and David Krathwohl (who was one of the editors of the original Taxonomy) The names of six major categories were changed from noun to verb forms. The word knowledge was inappropriate to describe a category of thinking and was replaced with the word remember instead. Comprehension and synthesis were retitled to understand and create respectively, in order to better reflect the nature of the thinking defined in each category. Create was moved to the highest, that is, most complex, category The revised Taxonomy is not a cumulative hierachy
The single dimension of the original Taxonomy has been replaced by two dimensions. As a cognitive process category, Knowledge was a replaced by Remember. Then, as a separate Knowledge Dimension, knowledge was “unpacked” (as we shall see later).
The two dimensions are part of a grid where the cognitive process dimension is spread horizontally across the top and the knowledge dimension is spread vertically.
Let’s take a closer look at the Cognitive Process Dimension.
Review each verb going through the revised Taxonomy’s definition and the corresponding verbs in each category.
Review each verb going through the revised Taxomony’s definition and the corresponding verbs in each category.

Now, let’s turn our attention to the Knowledge Dimension.
There are four types of knowledge.
Recipes have two parts, a top part and a bottom part. The top part includes the ingredients. The bottom part describes what the cook is supposed to do with the ingredients. In the terminology of the revised Taxonomy, the top part contains the basis for Factual Knowledge (the details) while the bottom part contains the basis for Procedural Knowledge (the steps to follow). More advanced cooks may bring Conceptual Knowledge to the recipe; others may involve Metacognitive Knowledge in the preparation of the Hot Artichoke Dip.
Review information on Factual Knowledge. Review recipe to illustrate Factual Knowledge.
Review information on Conceptual Knowledge; use recipe to talk about how Conceptual Knowledge differs from Factual Knowledge. Finding a package that says Parmesan cheese because the recipe calls for Parmesan cheese is an example of Factual Knowledge. Knowing where Parmesan cheese fits into the general category of “cheeses” is an example of Conceptual Knowledge. With Conceptual Knowledge, you can make proper substitutions of ingredients. With Conceptual Knowledge, for example, you can determine whether it is possible to substitute Salad Dressing for Mayonnaise.
Review information on procedural knowledge, using the steps in the recipe to illustrate the composition of procedural knowledge. Emphasize the sequential nature of procedures. Sometimes “next,” “then,” and “now” are used instead of 1, 2, 3, and so on.
Review the information on metacognitive knowledge; unlike the other types of knowledge which derive primarily from the subject matter being taught, metacognitive knowledge derives primarily from individual students. Indicate how metacognitive knowledge allow cooks to make recipes “their own.” They make strategic modifications in the procedural knowledge. They know which recipes are difficult for them and which are easy. They know what recipes are their “signature dishes.”
So this is the way the entire Taxonomy Table looks. REVIEW ONE MORE TIME: CHANGING EMPHASIS Two dimensional Verb represents the cognitive process dimension Noun represents the knowledge dimension Twenty-four cells that are all important and necessary for well-rounded understanding Authentic tool for curriculum planning, instructional delivery and assessment Allows for examination of alignment objectives, instruction, and assessment Not a cumulative hierarchy – lower levels are NOT necessary for advancement through levels
Get participants’ answers and then emphasize flexibility. In problem solving, for example, the cognitive processes can be used in any order.
