I describe two aspects of metacognition, knowledge of cognition and re
gulation of cognition, and how they are related to domain-specific kno
wledge and cognitive abilities. I argue that metacognitive knowledge i
s multidimensional, domain-general in nature, and teachable. Four inst
ructional strategies are described for promoting the construction and
acquisition of metacognitive awareness. These include promoting genera
l awareness, improving self-knowledge and regulatory skills, and promo
ting learning environments that are conducive to the construction and
use of metacognition.
