From faculty member Dominic Smith‘s’ 2009 residency lecture, “Varieties of Movement: Plot and Beyond in Fiction”:

I prefer to use the term plot dynamic rather plot type to convey the notion that plot is best understood as a fluent tendency, a unifying force, rather than an absolute category. Like light it can be more than one thing at once, container and type as well as force and energy.

Dominic is the author of Bright and Distant Shores: A Novel(2011, Washington Square Press).  This lecture is available for purchase from the MFA Program website.
