How/That

Knowledge can be described as either procedural skills or declarative knowledge.  A procedural skill is claimed by stating “I know how to…”, and declarative knowledge is claimed by stating “I know that… ”. Procedural skills and declarative knowledge are visible, measurable, and tacit. 

If I say, “I know how to … ride a bike”, there’s a way to demonstrate that knowledge.  If I say, “I know that … the Pythagorean Theorem will help solve this problem”, that knowledge can be demonstrated. 

One way to demonstrate what we know, is to categorise by “I know how to…” or “I know that…”.
