Introduction and Background:
Bloom's Taxonomy
In the 1950's Benjamin Bloom developed his taxonomy of cognitive objectives, Bloom's Taxonomy. This categorized and ordered thinking skills and objectives. His taxonomy follows the thinking process.

It is a continuum from Lower Order Thinking Skills (LOTS) to Higher Order Thinking Skills (HOTS).
