This article presents the current status and new perspectives on the Struct
ural Learning Theory (SLT). Special consideration is given to how SLT has b
een influenced by recent research in software engineering, and the range of
possibilities it opens for instructional research and practice in the twen
ty-first century. Starting with fundamental precepts of the instructional p
rocess, a generalization of the SLT is proposed that offers an integrated,
parsimonious, operational and predictive (as well as explanatory) account o
f competence, cognition and behavior potentially from birth onward, and the
ir implications for instruction. Supporting examples and experimental resea
rch are cited in context.
