Methods
A phenomenographical approach was chosen for the
study, which includes two research perspectives: the first
order perspective, which is the description of the world
as it is and the second order perspective, which is the
description of the world as it is experienced [27]. The
second order perspective is emphasised in phenomenography
and interviews are the most common way of collecting
data. The method was developed in the 1970s by
Marton and his co-workers, and originates from an empirical
educational framework. The focus is on how
people experience and perceive a given phenomenon
and not on the phenomenon itself. The interest lies in the variety of ways humans have of understanding the
world around them [27].
Individual interviews present different conceptions
which form categories of description in an analysis. The
categories of description represent a collective level of
the various conceptions [27,28].
