Also from Freeman (1813), "...the learning of the letters in their detached situation, is a dry, tedious, discouraging process. But learning them, in learning words, is, it is presumed, much more tolerable. Indeed, the difference resembles that which is experienced by two travellers engaged in a toilsome journey, one of whom is amused with a variety of objects that attract his notice, and thus beguile the tediousness of the way; while the other sees no beauty in the surrounding scenery, but is perpetually poring over his present toil, and the disheartening distance that separates him from the end of his journey. We always like to observe too, that we are making a progress; and this animates us, in encountering difficulties. On the other hand, if we seem to make no advances, we are in great danger of abandoning our pursuit." (pg. 17)
A conceptual framework of learning on which domain-specific, individualized, theories of learning can be constructed.
