The half-life of knowledge

Interdisciplinarity

Beyond the way knowledge is acquired, we are also grappling with working in an increasingly VUCA (volatile, uncertain, complex, and ambiguous) world. In such a context, can we continue to hold a siloed view of domain disciplines? In training law students, for example, we would be remiss not to show them basic programming, which can allow them to create customised commands to quickly and easily trawl through databases, with millions of legal records, to identify precedents.

Deep domain expertise is like a laser – a focused beam of knowledge that can cut through dense problems. However, real-world issues are increasingly multifaceted and ill-defined, often lacking a clear vulnerable spot at which a laser beam can be aimed. 

As a mental experiment, consider the challenge of introducing autonomous electric vehicles to a city. This proposition involves urban design, city planning, the law, and engineering for accessibility. We can form a multidisciplinary team of experts, where each member is a domain expert, to tackle the issue. However, in all likelihood, we will encounter misalignment between domains, simply owing to differences in problem-solving methodology, thinking models or even nomenclature.  

If we liken domain training to equipping students with specific lenses through which they can see and focus on information to solve a problem, then interdisciplinarity suggests that we should train students to operate across more than one domain. By educating them in core ideas from multiple domains and providing opportunities to apply their knowledge in authentic settings, students with interdisciplinary training can switch domain lenses as needed, solving problems using novel and unorthodox approaches that transcend domains.

To be clear, we are not advocating for dismantling deep domain training. Rather, we recognise that there is now an indisputable requisite to equip graduates with interdisciplinary knowledge and skillsets. We need both the agile lenses of interdisciplinarity as well as the deep-cutting laser of deep domain expertise. The former trains us to aim and focus the laser, while the latter allows us to cut to the heart of a problem.  

NUS strongly believes in providing interdisciplinary pathways for our students. In 2020, we created the College of Humanities and Sciences (CHS) to provide an enhanced interdisciplinary undergraduate experience for students of the Faculty of Science and the Faculty of Arts and Social Sciences. CHS undergraduates can choose between deep domain training or the flexibility of interdisciplinary training of varying breadth and depth in modules offered by both faculties. Continuing our efforts to pave more interdisciplinary pathways for students, in 2021, we merged the School of Design and Environment and the Faculty of Engineering to form the College of Design and Engineering. More recently, NUS launched NUS College, Singapore’s first honours college offering pathways to more than 50 majors across a half dozen degree programmes. The aim of NUS College, as explained by its inaugural dean, Professor Simon Chesterman, “[is to offer] broad, interdisciplinary competencies that equip students for life, along with the opportunity to dive deep into areas in which you are passionate.”

To quote Charles Dickens, “It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness.” Indeed, our experiences with the global pandemic and its effects on education over the past two years have given us the rare opportunity to engage in deep reflection and introspection. Witnessing the breakdown of resistance to adopting and adapting technology for teaching and learning during this time, we should be emboldened to re-examine and revolutionise some of our established, and perhaps outmoded, notions of how to offer higher education.
