Content Vs Domain

     Content reading is the ability to read and comprehend material of a particular subject area such as science, social studies or math. No prior knowledge is required and the reader can gain knowledge and understand the facts/information stated in the text.
     Domain reading is the process of the actual reading activity itself, the function of reading. Prior knowledge is necessary in order to comprehend the text.

     Content knowledge is the ability of a teacher to know content area or "core" of the subject matter and be able to instruct the content. It is the "how to" of teaching so that students can best learn the concept of a particular area. The most useful way of representing subject  content to enable students to better comprehend requires an "unpacking" or taking apart of the ideas, such as with problem solving in math. 
     Domain knowledge is the knowledge base about a specific field of interest based on trends, terminology, experience and expertise. It is the general, global knowledge about all areas of life and is critical for success.
