In the context of a course in assistive technology offered by the Departmen
t of Occupational Therapy at the University of Toronto, a practical exercis
e was conducted to better understand the physical and social barriers exper
ienced by wheelchair users. The purpose of the exercise was to sensitize st
udents to the ways in which the environment and people's attitudes can impa
ct on the lives of people who use mobility devices. Using structured field
logs, students recorded their observations of barriers experienced in diffe
rent environmental contexts over a 48-hour period in which they used a whee
lchair. Students rank-ordered each barrier in terms of perceived difficulty
on their occupational performance. This article describes the educational
exercise and students' reactions to the exercise. Implications of the educa
tional strategy and the findings that emerged will be discussed in relation
to professional education, clinical practice, and research.
