Abstract
This overview will focus on the advantages of strategy instruction as well as the components and principles that underlie effective strategy use. The advantages are related to (a) modifiable and planful activities, (b) individual differences and adaptation, and (c) instructional development. Principles of effective strategy use incorporate such factors as (a) different strategy purposes, (b) component analysis, (c) strategy matching to individual students, (d) processing differences and performance similarities, (e) comparable strategy use and noncomparable performance, (f) transformational strategies, and (g) learner constraints.
