The users' preference is an important role on the proposed CoD adaptation system, which is a subject concept depends on individual's understanding and perception.
But what he mainly seems to have in mind is that it is always in some sense up to us to decide how many and which characteristic marks to build into any given subject concept, and therefore how many and which judgments in which that subject concept features will count as analytic or as synthetic.
In both the Preamble to the Prolegomena to Any Future Metaphysics and the B-Introduction to the Critique of Pure Reason, Kant introduces the analytic/synthetic distinction, which distinguishes between judgments the predicates of which belong to or are contained in the subject concept and judgments the predicates of which are connected to but go beyond the subject concept, respectively.
However, Moore's characterization of a proposition as a complex of concepts was largely in keeping with traditional Aristotelian logic in which all judgments were thought to involve a subject concept, copula and predicate concept.
He follows this with an explanation of how such non-empirical judgments can yet be synthetic, that is, how they can serve to synthesize a subject and predicate concept rather than merely explicate or analyze a subject concept into its constituent logical parts.
In other words, to synthesize is in general to combine several representations into a single (more) complex representation, and to judge is specifically to combine concepts into a judgment — that is, to join a subject concept to a predicate concept by means of the copula, as in "the body is heavy" or "the house is four-sided".
In an analytic proposition, the predicate concept is contained in its subject concept; in a synthetic proposition, the predicate concept is not contained in its subject concept.
This fits the definition of the intended curriculum in which mathematics and science are seen as an interdisciplinary mix in which connections between these disciplines are placed while the subject specific concepts remain recognizable (Lederman and Niess [1997]).
Both these benefits of social tagging when applied to LORs aim to enrich the LO descriptions with information potentially useful to teachers either in terms of the content of the LO (e.g., subject domain concepts described by the LO) or in terms of how the LO can be used in teaching and learning (e.g., teachers' experiences from using the LO in their teaching practice).
Instead of monitoring hallways, teachers are available in labs for students who want help with a particular subject or concept.
