Facts and Concepts

My understanding of facts: concrete information that is objective. It describes the relationships among concepts.

My understanding of concepts: It is abstract and differed according to people's perceptive. Hence, it should be define operationally according to different context.

Although facts and concepts seems to be closely related, it is in different category according to Gagne's classification. 

Facts are part of declarative knowledge whereas concepts are classified as intellectual skills, although some would argue that concepts could be declarative knowledge in some situations. 

I think it is interesting while in the readings facts are only part of declarative knowledge, along with labels and names, facts and lists, and organized discourse, it is mentioned alongside with concepts in the lecture.

Since concepts are build up from facts, is it feasible to separate them during learning design? or we should automatically incorporate learning strategies for facts while designing learning strategies for concepts?
