hey marsie,
basically, the conceptual framework is made up of four agencies - the ARTIST (which is about the creator of the artwork, who they are, what they like etc), the ARTWORK (which is more about the materials used, the suject matter, basic concept and idea), the AUDIENCE (the people the artwork was made for and who views the artwork) and the WORLD (which consists of the artists immediate and outer world and their surroundings and/or contexts - whether it be social, political, cultural or from the media.
the are four frames in art -
the SUBJECTIVE FRAME; which basically deals with the personal aspect of the artwork, emotions etc
the STRUCTURAL FRAME; which is any signs or symbols that are present in the artwork, as well as the elements of art - line, tone, composition, colour, shape, pattern, texture etc
the CULTURAL FRAME; which deals with race, gender, culture, age and social issues. it is more like a cultural indication of teh personal context of the artist or even a comment on culture as a whole
the POST-MODERN FRAME; which is mostly taking something old or something already used in an artwork and changing it in some way to become your own new artwork or even a part or aspect of your artwork. it can be an object or even a basic idea, it depends on each individual's interpretation.
the artists practice is basically what materials the artist uses, how they make the artwork - their artmaking process - and how they get from teh concept to the resolution of the artwork (from the idea to the finished product).
hope this helps - good luck!
