Thinking skills are often divided into higher order thinking skills (HOTS) and lower order thinking skills (LOTS). Lower order thinking skills include remembering, understanding and applying. Generally speaking, LOTS involve focussing on and absorbing information, and less manipulation of information than HOTS do. (See Higher Order Thinking Skills). The division of thinking skills into HOTS and LOTS was made initially in the late 1940s by a committee of educators in Boston, Mass. chaired by Benjamin Bloom and colleagues. This taxonomy (known as Bloom’s Taxonomy) has been revised several times.
"‘Tell me what you did in the holidays’ or ‘Describe your family’ are typical ELT LOTS questions. An example of a HOTS question might be ‘What do you think of that film’?’ or ‘Compare your town with London’. You don’t need to think so hard for LOTS answers and the language you need to use is often simpler."
