Abstract— Laboratory work is a well-accepted component of
science and engineering programs. One emerging trend has been
the increasing utilisation of remotely accessed laboratories, where
the students can remotely monitor and/or control physical
apparatus, typically across the internet. This supports greater
flexibility of access for students as well as the possibility of
sharing of facilities between institutions. One additional benefit is
greater flexibility in designing the learning context within which
the laboratory can be positioned. As the interaction is computer
mediated, it becomes simpler to modify this interface and hence
change the laboratory context.
Research has shown that context can have a significant effect
on learning outcomes, students’ retention of information,
engagement with learning and on knowledge transfer from one
domain to another (see, for example, [1],[2]). Despite this there
has been little consideration given to understanding contextual
information provided in laboratories in general and remote
laboratories in particular.
In this paper we report on an analysis of contextual
information provided within remote laboratories. Consideration
is given to the ways in which the contextual information provides
a connection between the real-world concepts being explored and
the laboratory as a proxy for those concepts. The analysis shows
that there is a diverse range of approaches and representational
forms and suggests a new taxonomy that may be useful in
describing the context found in laboratory activities for future
analysis and design.

I. INTRODUCTION
All learning occurs within a context, irrespective of
whether that context has been actively constructed or is an
incidental or unintended consequence of either the learning
activity or the learner’s history. The nature of the context and
how this context relates to the concepts being learnt has been
widely shown to have an effect on learning outcomes [3], [4].
Whilst this effect has been studied in a number of disciplines
and over a range of different types of learning activities, we are
specifically interested in how context can be used in laboratory
activities – an area in which there has been relatively little
written.
In previous work [5] it was argued that the provision within
laboratory experimentation of an explicit domain context that
can clarify the relationship between the experimental apparatus
and a real-world situation which it can represent, could
potentially support improved learning outcomes. In particular,
this is based on the development of a clearer understanding of
the relationships between the aspects of reality being
investigated, the laboratory apparatus that is acting as a proxy
for that reality and the conceptual model that describes some
aspect of that reality.
Contextual elements that aim to clarify these relationships
between the laboratory, its underlying model and the real world
(including, importantly, where the relationships break down)
are present in many laboratory activities but often their
inclusion is done without systematic consideration of the
design of these elements.
In order to begin reasoning about context in laboratories it
would be beneficial to analyse existing laboratory activities to
determine the different forms and functions that exist in the
contextual elements of a range of laboratories. This would
support the development of a framework that can be used to
analyse and subsequently strengthen contextual aspects of
existing laboratories as well as design contexts for new
laboratories in such a way as to support laboratory learning
outcomes.
Remotely accessed laboratories which, by necessity, have
computer mediated interfaces, have provided educators with
the opportunity to modify lab interfaces and supply contextual
information in new formats (as opposed to laboratory notes and
instruction). The literature presents a number of learning
activities using remote labs that have been enhanced in such a
way to support learning outcomes, however few of these
specially look at the nature of the context provided [6]. Remote
laboratories provide a suitably varied range of contextualisation
to begin this analysis.
In this paper we look at the types of contextual elements
that are relevant to laboratories, and the ways in which these
might be classified. We begin by analysing existing literature
to determine how context is currently described, with a
particular emphasis on considering science education.
Focusing on domain context, the ideas are then applied to a
diverse range of remote laboratories in order to develop a
