How can we evaluate the quality of learning experiences?

Among other things, Bloom’s taxonomy allows us to categorize learning experiences. Bloom’s work was revised somewhat by Anderson a bit later, and it’s that revised edition I’ll describe here.

A taxonomy is a way of arranging things, and the revised Bloom’s taxonomy has two dimensions for categorization, the knowledge dimension and the cognitive dimension. Here they are in tables with examples.

Knowledge Dimension

Level Example
Factual knowledge Crude oil can be made into gasoline
Conceptual knowledge Crude oil is a mixture of many different hydrocarbons including gasoline.
Procedural knowledge Mixtures of chemicals in general can be separated through distillation, including gasoline from crude oil.
Metacognitive knowledge Determining if a chemical mixture can be separated with distillation is possible through internet searches or experimentation with different temperatures.

Cognitive Dimension

Level Example
Remember Crude oil can be made into gasoline
Understand Draw diagram showing how gasoline is extracted from gasoline
Apply Set up alcohol distillation in test tubes
Analyze Given a set of 20 liquids, determine which are mixtures separable by distillation
Evaluate Compare your methods to those of your classmates
Create Try to make brandy by distilling wine (not quite kid friendly.. :D)
