Graduate education has long focused on depth in the disciplines. Academic disciplines have provided a system for organizing scholarship through academically accepted set of methodologies, professional journals and professional societies. Disciplines tend to have a critical mass of scholars and educate students in the cultural norms of the discipline. They have served and will continue to serve higher education well but more is needed.
With strong disciplinary foundations, we must now move and actively embrace and engage more in interdisciplinary graduate education. Due in part to the inherent complexity of nature and society, very interesting and challenging research questions can be found at the interface between and among disciplines – these will require an interdisciplinary perspective. This leads scholars and graduate students to explore problems and research questions that are not confined to a single discipline and require collaborative endeavors. National agencies (e.g. NSF, NIH) have called for more interdisciplinary efforts and provided funding opportunities such as the Integrative Graduate Education and Research Training (IGERT) programs.
This brings me to the topic of depth or breadth and beyond. Arguments are frequently put forward that graduate education should focus on depth of knowledge and thus, we must maintain a disciplinary focus and focus on the disciplines. Along with this argument, it is often acknowledged that although interdisciplinary graduate education does provide valued breadth, it lacks the depth. I’ve worked with interdisciplinary graduate education for the past 20 years and would argue that interdisciplinary research not only requires but can achieve both depth and breadth as well as integration for success.
In my recent musings about interdisciplinary graduate education and research, I have come to visualize those with the depth of training and education in the discipline as I-educated individuals, those with the depth and breadth of training and education plus the ability to work across disciplinary lines at T-educated individuals, and those individuals with breadth and depth of education and training in more than one discipline and the ability to integrate knowledge across disciplines as Pi (π)-educated individuals. Through this lens, knowledge seems to be grounded in and emanate from the disciplines and then integrated across boundaries. These are the scholars and scientists who will be able to serve as the adaptive innovators of and for the 21st century.
