Abstract
This article addresses the interrelated questions of why it is important to teach students
about the nature of interdisciplinarity and how this material might be best communicated
to students. It is important to define for students what is meant by disciplines and
interdisciplinarity. Having distinguished interdisciplinarity from the disciplinary
approach, the advantages and disadvantages of each can be discussed. It is useful to
discuss the history of both disciplines and interdisciplinarity. It is also useful to discuss
the complex relationship between interdisciplinarity and other intellectual currents:
postmodernism, unity of science, complexity analysis, feminism, and others. Critically,
students should be guided as to how interdisciplinary research might be best performed.
Some potential objections to teaching interdisciplinary research practice are addressed.

1. Introduction
This article will first address the question of why it is thought that it is important and
valuable to teach interdisciplinary research practice--ideally in one or more courses
devoted to this topic. This article addresses some potential objections to doing so before
turning to the question of how to do so. The How and Why questions are obviously
interconnected: scholars will not convince themselves of the desirability of doing
something without having some idea of how to do it. This introductory section thus closes

with brief remarks that tie the Why and How questions together by addressing also
questions of What and Why Now.
What does it mean to teach explicitly about interdisciplinary research practice? While
different programs (and texts) emphasize different topics, some key elements can be
found across most of these endeavors. Foremost, it is important to define what is meant
by disciplines and interdisciplinarity. While competing definitions exist in both cases, the
literature has advanced to a degree where an interdisciplinary scholar can readily discuss
the key elements of such definitions. In particular, the scholarship on interdisciplinarity
generally, though not always, stresses the importance of integration: the need to critique
the insights of different disciplines and to seek common ground when these insights
disagree. The insights of a discipline are the specific arguments it makes about the nature
of a particular phenomenon (a society’s income distribution, or attitude toward
punctuality, or fertility rate, or a particular work of art), or how one phenomenon
influences another. Such insights, as we shall see, need to be evaluated in the context of
the discipline’s favored theories, methods, and overall disciplinary perspective. Having
distinguished interdisciplinarity from disciplinary research, the advantages and
disadvantages of each can be discussed. I will stress a symbiotic relationship.
Here it is possible to discuss certain values inherent in the interdisciplinary approach but
not always stressed within disciplines: open-mindedness, tolerance of different points of
view, and pursuit of a conversation aimed at enhanced understanding rather than victory
for one point of view. It is useful, though less common, to discuss the history of both
disciplines and interdisciplinarity. It is also useful to discuss the complex relationship
between interdisciplinarity and other intellectual currents: postmodernism, unity of
science, complexity analysis, feminism, and others. Finally, one should address the
question of whether there is an interdisciplinary method or perhaps a set of
interdisciplinary best practices or an ideal interdisciplinary process, and what the
elements of such an interdisciplinary approach to research might be. While the notion of
interdisciplinary research practice in its broadest sense encompasses all of the above
elements, much of our attention in this article will focus on outlining an interdisciplinary
research process and how this can be communicated to students.
Why now? The literature on interdisciplinary research practice has matured in the last 2
decades. While consensus may be rare, it is much easier today to identify and understand
competing points of view on a range of issues relevant to interdisciplinary teaching and
research. There is at least consensus on some of the key questions to ask, which is, in
itself, an important step forward. Over the last decade I have regularly attended the
annual conferences of the Association for Integrative Studies (AIS), a scholarly
association devoted to the study and support of interdisciplinarity in both teaching and
research. Over that decade, a noticeable change has occurred. While most curricular
space in interdisciplinary programs is still devoted to modeling interdisciplinary research-
-that is, to discussing the process and results of particular pieces of interdisciplinary
analysis--such programs increasingly include some component that explicitly addresses
how and why interdisciplinary research should be performed. This material places in
context the many examples of interdisciplinary research provided in other courses. I

created such a course at the University of Alberta, Canada, and taught this for the first
time during the 2005-2006 academic year. This change in approach is best reflected in the
publication of the first two textbooks in the field, Augsburg (2006) and Repko (2008).
Augsburg and Repko speak of their intellectual debt to previous authors, notably Julie
Thompson Klein and William H. Newell--and perhaps especially to the anthology edited
by Newell (1998). Repko also draws upon some of my earlier work (particularly Szostak,
2004).
Mention should also be made of the journal, Issues in Integrative Studies, and especially
the debate regarding the nature of interdisciplinarity in the 2001 and 2002 issues of that
journal. The European literature of transdisciplinarity is introduced on the Web site of
the International Center for Transdisciplinary Research (CIRET). While the term
transdisciplinarity at one time signified an insistence on integrating beyond the academy
(an orientation also embraced by many interdisciplinarians), its meaning today is often
very similar to that of the term interdisciplinarity.
This material should, of course, be taught primarily with the aim of informing students
rather than impressing administrators:
(a) Such material provides students with an understanding of their program which will
facilitate their drawing connections between different courses in the program. This is true
both for programs in “interdisciplinary studies” itself as well as for thematically oriented
programs such as environmental and gender studies. If students never discuss how and
why interdisciplinary analysis is performed, they may have little appreciation of why they
deal with political economy in one course and social psychology in the next, and
especially how they might tie the material from these courses together.

(b) The course should help students appreciate connections not only within their
interdisciplinary major but across all of their courses. Gerald Graff has bemoaned in
various publications the ability of students to compartmentalize knowledge: to not even
recognize that their political science professor and economics professor are addressing
the same subject (aided by the use of different jargon in different disciplines), and thus
not feel any need to ask why they reach different conclusions. Graff’s (1992) advice that
we “teach the conflicts” means in practice that we must teach students to first recognize
the different insights that flow from different disciplinary (or other) perspectives and then
provide them with some tools for resolving these conflicts. This, of course, is the central
purpose of interdisciplinarity. Notably, then, a powerful case can be made that such
material should be taught to all students, a possibility that might readily be implemented
at institutions that have core courses for all students (such as the general education
requirements in the United States).
(d) The course should help students communicate the nature of interdisciplinary research
practice to various nonacademic audiences. Students need to justify and explain their
majors to parents, friends, and prospective employers. These others will often think they
know what chemistry or history is all about, but will wonder about more novel
interdisciplinary programs. Students in interdisciplinary programs thus are more likely to
be queried regarding the nature of their education. They may struggle to answer such
queries without explicit curricular content devoted to this (see Augsburg, 2006). This
learning exercise can usefully be interactive if students are asked to write brief essays on
what they expect to learn from their degree during their first or second year and also later.

3. Why Not?
A second practical problem is simply that most program curricula are already filled with
requirements. Adding a new requirement must mean giving something up (and/or
discouraging student enrollment). This should not be a problem if it is accepted that the
material recommended in this article should lie at the core of an interdisciplinary (indeed
any) education. In practice, though, practical concerns regarding what must be given up
(and the institutional politics that often lies behind such concerns) will often be expressed
as pedagogical concerns regarding what is to be added.
It is sometimes argued (and I have witnessed these arguments myself) that the suggested
material is too meta-theoretical, too far removed from the real-world problems that
interdisciplinary research usually addresses. I must confess here to being well disposed to
meta-theory. I think students in an undergraduate program need to develop some
philosophical appreciation of the limits to the validity of all the “stuff” they would have
learnt at the end of 4 years. Likewise, they also need to appreciate the nature and limits of
ethical/moral reasoning as they are continuously exposed to ethical/moral judgments
from teachers and peers. But the case here for meta-theory is even stronger: if the central
premise of an interdisciplinary program is integration then we cannot escape the
responsibility of teaching students how and why to do so.

This section suggests that concerns that it is not desirable to teach this material can often
be deconstructed into concerns that it is not possible to do so. In other words, the question
of why to teach this material cannot be separated from the question of how to do so.
This section introduces several topics that should be addressed in a course about
interdisciplinary research practice and discusses how the literature with respect to each
might be addressed in practice. I will try to model here how instructors might introduce
students to various debates while not being shy about confessing to their own (hopefully
internally consistent) preferences with respect to each. That is, while I have my own
preferences regarding whether interdisciplinarians should seek to destroy disciplines or
build upon their insights, and pursue grand theory or more localized integration, I think it
important that students be exposed to both sides of such debates in an open-minded
manner.
One of the key characteristics of a discipline is the worldview or perspective that shapes
research and teaching in the discipline. This embraces the four elements below, but also
elements of ethics, aesthetics, and ideology (Klein, 1990; Salter & Hearn, 1996; Szostak,
2003):
Students should appreciate that disciplines evolve through time and also that there is
diversity within each one. Nevertheless, the above features are important to the
interdisciplinarian in understanding the insights generated by a discipline at a point in
time. In particular, interdisciplinarians should appreciate the interdependence among
these: disciplines choose methods that are well suited to the investigation of their favored
theories, phenomena that can readily be studied with these theories and methods, and
rules of the game that reward the application of the favored theories and methods to the
favored phenomena.
Klein and Newell have provided a definition of interdisciplinarity which has received
widespread support:
Page 6 of 16
Published by AU Press, Canada Journal of Research Practice
While I quite like their definition, I have attempted a complementary definition which
lays equal stress on each of the five characteristics of disciplines noted above (though I
should have used the word integration rather than application):
(a) Is integration essential? Klein and Newell would argue that simply adding together
disciplinary insights is just multidisciplinarity, while integrating these is necessary for
interdisciplinarity. The term transdisciplinarity used to mean integration not only within
the academy but with community groups as well, but its meaning has evolved to
approximate interdisciplinarity. Klein and Newell (1996) have suggested that integrating
within and outside the academy involve similar processes.
While Lattuca (2001, p. 23) concurs that “[m]ost scholars define the locus of
interdisciplinarity as the integration of disciplinary perspectives,” she worries that such a
conceptualization “conceals the disciplinary critiques that drive much interdisciplinary
scholarship today” (2001, p. 4). Moran (2001) likewise downplays the role of integration.
Students can and should be introduced to forms of “critical interdisciplinarity” that do not
stress integration, while recognizing that most interdisciplinary analysis is problem-based
and integrative (Salter & Hearn, 1996, p. 30).
(b) What is integration? The closest synonym is synthesis. Integration involves first an
important element of critical reflection: what are the strengths and weaknesses of
different disciplinary insights, and how might they reflect biases inherent either in
disciplinary practice or more general academic practice (or indeed limitations to human
perception and reasoning). Integration then involves finding common ground among
different disciplinary insights.
(c) What is the most important focus of integration? As Repko (2008) argues, it is the
insights generated by different disciplines that the interdisciplinarian seeks to integrate. In
order to evaluate these and find common ground, one needs to understand the theories,
methods, and phenomena in which these insights are grounded, and the overall
perspective of the discipline. One can identify, for example, the main strengths and
weaknesses of different methods and theories (Szostak, 2004). Moreover, a discipline’s
preferences with respect to phenomena, theories, and methods are important components
of its disciplinary perspective. Attempting to draw on disciplinary perspectives in
interdisciplinary research will be unnecessarily challenging if perspectives are not
defined carefully in terms of such elements.

What role should disciplines play in interdisciplinary research and teaching? The Klein
and Newell definition grounds interdisciplinary analysis in the disciplines, highlighting
the task of building upon disciplinary insights. Others take a less positive view of
disciplines and see interdisciplinarity as a revolutionary process whose goal should be the
subversion of disciplines (Carp, 2001). Naturally, they emphasize the value of interacting
with nonacademics. However, interacting with nonacademics appears to be welcomed by
all interdisciplinarians. Klein and Newell seek a compromise attitude toward disciplines
that stresses that interdisciplinarity can change disciplines.
One obvious element of common ground here is that both points of view recognize
important limitations to disciplinary analysis. They differ only in the degree to which
they find value in disciplines. There can be an empirical resolution to this difference: one
can apply agreed-upon procedures of interdisciplinary analysis in order to critique
disciplinary insights, and evaluate how useful these insights might be in specific cases.
The words disciplinary and interdisciplinary can give rise to the mistaken idea that
interdisciplinarity is an optional add-on to the core operation of disciplinary scholarship. I
think the symbiotic view will be better served by using different words, specialized and
integrative, to refer to the two types of scholarship, hinting at the potential contribution
from each.
There are two important historical facts that students of interdisciplinarity should note.
The first of these is that disciplines themselves are relatively new. To be sure, different
fields of research and teaching have long existed. The ancient Greek academies already
distinguished among several subjects: music, grammar, arithmetic, and so forth. But
Page 8 of 16
Published by AU Press, Canada Journal of Research Practice
disciplines as defined above, with consensus on theory, method, subject matter, general
outlook, and publication and hiring practices, simply did not exist until the eighteenth or
nineteenth centuries. The German research universities were important in establishing
departments which tended to hire only professors with degrees in that discipline. Still,
late in the nineteenth century, Max Weber, one of the leading figures in modern
sociology, would spend much of his career occupying a chair in economics. Specialized
academic journals came gradually to supplant more general publications. Disciplines
began perpetuating themselves through their institutionalization in departments and
journals. Turner (2000) argues that most characteristics of disciplines flow from the
reality of departments hiring only scholars with PhDs in those disciplines.
It is sometimes said that writers such as Aristotle, Hume, or Adam Smith were
interdisciplinary. These writers can be more correctly thought of as pre-disciplinary. They
roamed across a landscape where disciplinary boundaries had not yet hardened. The
appeal of “great books programs” (i.e., educational programs based on a curriculum of
selected material from a list of “great books”--such a list is maintained by The Great
Books Foundation) reflects in large part the wide-ranging contemplations of such writers.
But they did not face the challenges faced by today’s interdisciplinarians, who must
confront a set of disciplinary discourses.
The second useful historical fact involves interdisciplinarity itself. Necessarily, this must
be newer than disciplines. One can identify concerns with the narrowness of disciplines
as soon as disciplines emerge. Interdisciplinarity has ebbed and flowed in popularity over
the last century or so. This ebb and flow might lead pessimists to predict that the present
interest in interdisciplinarity will inevitably dissipate. The symbiotic perspective outlined
above leads us to understand these ebbs and flows in terms of a conflict between the
desirability of interdisciplinarity and the difficulty of pursuing interdisciplinary research
or teaching successfully. Previous incarnations of interdisciplinarity, including the
interwar blossoming of the “unity of science” movement, tended to stress a search for
unifying grand theories. Today’s interdisciplinarity usually stresses instead integration
across different theories: the goal for most scholars is no longer one big theory but a large
number of theories each casting light on different (and overlapping) facets of the world in
which we live. This arguably is a much more achievable goal.

Published by AU Press, Canada Journal of Research Practice
Many interdisciplinarians would worry that we cannot have both shared process and
revolutionary imagination. An important task of subsection 4.5 is to argue otherwise. In
other words, I will suggest that we can best think outside the box if we know what the
interdisciplinary box looks like.
When I have taught interdisciplinary research practice myself, I have devoted much class
time to postmodernism in particular, since interdisciplinarity, especially in the
humanities, is often compared with or even confused with postmodernism.
Postmodernism comprises a set of critiques of the contemporary academy and its
discipline-based organization. Thus it is hardly surprising that many postmodern critiques
resonate with interdisciplinarians; particularly concerns about scholarly biases, suspicion
of overarching meta-narratives, and the celebration of diverse points of view. But
interdisciplinarity must in the end hinge on a belief that we can, through integration,
achieve understandings that are in important ways more comprehensive and less biased
than disciplinary insights--and some versions of postmodernism would doubt such a
possibility. The very possibility of adding to the body of human understanding needs to
be defended against the more extreme version of postmodern thought (Szostak, 2006).
Other important intellectual currents, such as feminism, complexity research, and the
unity of science movement, share many of the postmodern concerns. However, some
versions of these pursue some grand theory that will explain much or all of human
existence, instead of reflecting the postmodern suspicion of meta-narratives. As noted
above, most interdisciplinarians no longer pursue grand theory. This important distinction
should also be brought out in courses on interdisciplinarity.
The textbook by Repko (2008) builds on works such as Newell (2007) and Szostak
(2002) to develop guidelines for how students should perform interdisciplinary research.
Students should in general follow the same research guidelines as scholars, though they
will most often not be able to devote as much time to each step in the research process.
These guidelines should be flexible because the interdisciplinary research process cannot
be “disciplined” but must embrace multiple perspectives (Newell, 2007, p. 247).
Moreover, the guidelines must be iterative: researchers will almost certainly want to
revisit earlier steps while performing later steps.
Page 10 of 16
Published by AU Press, Canada Journal of Research Practice
The next step(s) must involve the gathering of relevant disciplinary insights. How does
the researcher know where to look? There are two complementary strategies. One is to
reflect on the nature of different disciplines and identify those that are likely to have
something to say about the issue of concern. The second is to ask what phenomena,
theories, or methods are implicated, and then ask which disciplines study each
phenomenon identified and/or apply each theory or method. Szostak (2004) develops
exhaustive classifications of phenomena, theory types, and methods to facilitate the latter
approach: in the absence of these it is all too easy to be seduced by disciplinary emphasis
on a subset of relevant theories, methods, or phenomena. Repko (2008) identifies the key
elements of disciplines in terms of these and other classifications. One challenge the
interdisciplinary researcher will face is that library catalogues are organized by
disciplines, and different terms are used in different disciplines to refer to the same
phenomenon, theory, or method. I have argued elsewhere that library classifications both
could and should be interdisciplinary in orientation, classifying works in terms of
universal classifications of phenomena, theories, and methods (Szostak, 2004, chap. 7,
2007, in press). An issue of Library Trends in 1996 (Volume 45, Number 2, themed issue
on “Navigating among the disciplines: The library and interdisciplinary inquiry”),
contains several ideas on how libraries can adapt the existing knowledge taxonomies and
classification schemes to facilitate interdisciplinary scholarship. Claudio Gnoli and
colleagues have begun to develop a classification scheme for this purpose: Integrative
Level Classification (ILC).
It is often noted that we live in an age of information explosion. Even disciplines cannot
hope to acquaint students with the full range of disciplinary research. In such an
environment, education should not focus on the transmission of a set of facts. Rather,
education should stress skills such as asking the right question, knowing where to find
information, and knowing how to utilize it. The interdisciplinary process involves such
skills, and is thus particularly well suited to the needs of contemporary students.
Page 11 of 16
Published by AU Press, Canada Journal of Research Practice
Having gathered the relevant disciplinary insights, the interdisciplinary researcher must
then critically examine the same, exercising critical thinking skills such as distinguishing
assumptions from arguments and evidence from assertions. In this respect,
interdisciplinarity differs from those elements of postmodernism which mistrust critical
thinking on the ground that all opinions are equally valid (Halperin, 1997, p. 6).
Interdisciplinary research can draw upon several unique strategies for critique:
(a) Asking how an insight might have been shaped by a particular disciplinary
perspective
(b) Asking how an insight might have been shaped by the theories and methods used by
the discipline
(c) Asking how the insight might have been different had the discipline in question
examined a wider set of phenomena
(d) Asking whether the insights from one discipline would point to possible weaknesses
in the insights from another discipline
(e) Asking whether some understanding from outside the academy would point to
possible weaknesses in a disciplinary insight
This process of critical inquiry responds to a complaint made by Katzer and Crouch:
“rarely are students taught how to evaluate what they need to read” (Katzer & Crouch,
1998, p. 3). It is also worth stressing here that evaluation can generally proceed without
requiring that the researcher be expert in the discipline in question (Newell, 2007).
Finally, some common ground needs to be achieved that would integrate the insights of
various disciplines. This calls for creativity, intuition, and inspiration. As the history of
science suggests, scientific breakthroughs usually reflect creative integration within a
well-prepared mind (see, for example, Root-Bernstein, 1989). However, it would be
extremely dangerous to identify interdisciplinary research with such sorts of
“revolutionary” insights. As should be clear by now, interdisciplinary research can
proceed as “normal science.” While it can and should set the stage for creative insight, we
should not hold every research project, and certainly not every interdisciplinary term
paper, to the standard of revolutionary insight. To carefully identify appropriate
disciplinary insights and to critique these carefully is valuable interdisciplinary work, and
can be built upon in a cumulative fashion by later researchers. The process of finding
common ground can utilize the following strategies:
(a) One can first ask to what extent seeming differences in disciplinary perspective are
apparent rather than real: differences in terminology may mean that different disciplines
are not actually talking about the same causal process even when they appear to be. The
interdisciplinarian can often redefine concepts, or extend a concept from one discipline to
the subject matter of another.
Page 12 of 16
Published by AU Press, Canada Journal of Research Practice
(b) When concepts from different disciplines disagree, these can often be placed on a
continuum or within a classification: the tendency of economists to stress rationality and
of sociologists to stress irrationality can be handled by referring to the degree of
rationality that individuals might display in specific situations (Newell, 2007).
(c) An attempt can be made to overcome some of the remaining differences by making
possible alterations to the disciplinary assumptions.
(d) Finally, different disciplines might shed light on different aspects of the question at
hand. An interdisciplinary understanding will generally contain a combination of
understandings of the relationships between pairs of phenomena as well as of any
emergent properties in the system of phenomena under study.
The interdisciplinarian should then reflect on the results of their research, contemplating
the biases that might have crept into their own work. They should seek to identify ways in
which their integrative understanding might be tested. And finally they should
communicate their results in a format that is accessible to multiple audiences. This
involves appreciating both the knowledge bases of different audiences and their interests:
the results should be connected to issues that different audiences (including those
working within disciplines) already care about.
Of course, the above discussion is highly abbreviated. Much more advice on how to
perform interdisciplinary research can be given--without disciplining the
interdisciplinarian. Yet it must equally be stressed that this advice can be given within a
limited amount of curricular time. One (or maybe two) course(s) in a program can cover
all of the material suggested in this article. Ideally this material will then be reinforced in
other courses as instructors refer to it, and as papers and capstone projects are both
shaped by and evaluated with respect to it. But for the most part interdisciplinary
programs should find that this material is easily integrated into existing curricula.
As noted just above, the material referred to in this article should be reinforced
throughout the student’s education and used in the creation and evaluation of student
papers and projects. Interdisciplinary programs can then be evaluated in large part in
terms of how well students have mastered interdisciplinary research practice and how
well they apply this to questions relevant to the program. Wolfe and Haynes (2003 and
elsewhere) outline how various interdisciplinary skills can be identified in student papers.
Since life itself is an interdisciplinary adventure, student mastery of interdisciplinary
research practice will prepare students well for life. Programs that can illustrate success
in interdisciplinary skill acquisition not only serve their students but the broader mission
of universities to prepare students for life in a complex world.

5. Concluding Remarks
It is both possible and desirable to teach students about interdisciplinarity: what it is, how
it should be done, and how it relates to disciplines and other intellectual currents. The
questions of How and Why (and of What and Why Now) are interconnected: those who
doubt the feasibility will also often doubt the value of teaching such material. This article
has thus treated them together, and also pointed to a body of literature that can be drawn
upon in the teaching and learning of interdisciplinary research practice.
