"...we need a domain theory to explain what is easy, what is somewhere between
easy and hard, and what is hard. When we understand these things, we can measure, give
meaningful feedback, and can teach people who desire to do so how to rapidly progress from
lower to higher levels in either type of domain. These lead to the construction of learning maps
that reflect progress up the domain scales, or reveal standing on a map of individual difference
variables." (Bunderson, 2003, p. unknown --- pdf available online at http://www.edumetrics.org/papers/How_to_build_a_Domain_Theor.pdf)
