Content Literacy VS Domain Literacy

How should I define these terms? Let me start with literacy. What is literacy? Is it just having the ability to read and write? I think that it is much more.......I believe that literacy is having competence in a specified area. Music literacy is something that is acheived with much dedication and practice, but teaching music and being proficient in communicating the knowledge that I have to others is a little different. I believe that this is the difference between content knowledge (literacy) and domain knowledge (literacy). Content literacy is the ability to use reading and writing for the acquisition of new information. It identifies three principal cognitive components: general literacy skills, content specific literacy skills, and prior knowledge of content. Domain literacy is the ability to access information, manage information, develop information, evaluate information, and communicate information. Understanding the difference is what great teachers do. They can gather needed information from students, develop, manage plans and implement strategies for improvement, communicate valuable and instructional feedback, evaluate, analyze, and assess student's progress. This reminds me of the "tried and trusted" Bloom's taxonomy. Bloom's was the way to create great lesson plans way-back-when...............if it ain't broken, don't fix it!
