  A good amount of research has explored the use of wearables for educational
or learning purposes. We have now reached a point when much literature can be
found on that topic, but few attempts have been made to make sense of that
literature from a holistic perspective. This paper presents a systematic review
of the literature on wearables for learning. Literature was sourced from
conferences and journals pertaining to technology and education, and through an
ad hoc search. Our review focuses on identifying the ways that wearables have
been used to support learning and provides perspectives on that issue from a
historical dimension, and with regards to the types of wearables used, the
populations targeted, and the settings addressed. Seven different ways of how
wearables have been used to support learning were identified. We propose a
framework identifying five main components that have been addressed in existing
research on how wearables can support learning and present our interpretations
of unaddressed research directions based on our review results.
