Toward an Effective Pedagogy of Climate Change: Lessons From a Physics Classroom

A major roadblock to effective climate education is the lack of radical visions (Kwauk, 2020) for engaging with climate change and related social-environmental crises in the classroom. Key aspects of the climate system: its inherent complexity and transdisciplinarity, the entanglement of social and natural systems, and the fact that it spans large scales of space and time - all present serious challenges to our modern, compartmentalized formal education systems. I present an argument for a justice-centered, inter-to-transdisciplinary conceptualization of climate change at the nexus of science, society and justice, which is designed to engage with the very features of the climate system that make it challenging. Based on pedagogical experiments in an undergraduate physics classroom for non-science majors, I identify five general barriers to teaching climate change, and formulate four dimensions of an effective climate pedagogy: the scientific-technological, the transdisciplinary, the onto-epistemological, and the psychosocial action dimensions. Within the context of a collaborative classroom culture informed by transformational learning, I describe the use of a meta-conceptual framework that, along with the issue of climate justice, seeks to realize all four dimensions of an effective climate pedagogy. This broad holistic framework is potentially adaptable to contexts and disciplines beyond undergraduate physics.

The Elephant in the Room: Why Transformative Education Must Address the Problem of Endless Exponential Economic Growth

A transformative approach to addressing complex social-environmental problems warrants reexamining our most fundamental assumptions about sustainability and progress, including the entrenched imperative for limitless economic growth. Our global resource footprint has grown in lock-step with GDP since the industrial revolution, spawning the climate and ecological crises. Faith that technology will eventually decouple resource use from GDP growth is pervasive, despite there being practically no empirical evidence of decoupling in any country. We argue that complete long-term decoupling is, in fact, well-nigh impossible for fundamental physical, mathematical, logical, pragmatic and behavioural reasons. We suggest that a crucial first step toward a transformative education is to acknowledge this incompatibility, and provide examples of where and how our arguments may be incorporated in education. More broadly, we propose that foregrounding SDG 12 with a functional definition of sustainability, and educating and upskilling students to this end, must be a necessary minimum goal of any transformative approach to sustainability education. Our aim is to provide a conceptual scaffolding around which learning frameworks may be developed to make room for diverse alternative paths to truly sustainable social-ecological cultures.

Vacuum structure of pure gauge theories on the lattice

We present results from simulations on two aspects of quark confinement in the pure gauge sector. First is the calculation of the profile of the flux tube connecting a static $q \bar{q}$ pair in $SU(2)$. By using the Michael sum rules as a constraint we give evidence that the energy density at the center of the flux tube goes to a constant as a function of quark separation. Slow variation of the width and energy density is not ruled out. Secondly in the confined phase of lattice $U(1)$ we calculate the curl of the magnetic monopole current and show that the dual London equation is satisfied and that the electric fluxoid is quantized.

London relation and fluxoid quantization for monopole currents in U(1) lattice gauge theory

We explore the analogy between quark confinement and the Meissner effect in superconductors. We measure the response of color-magnetic "supercurrents" from Dirac magnetic monopoles to the presence of a static quark-antiquark pair in four dimensional U(1) lattice gauge theory. Our results indicate that in the confined phase these currents screen the color-electric flux due to the quarks in an electric analogy of the Meisner effect. We show that U(1) lattice guage theory obeys both a dual London equation and an electric fluxoid quantization condition.
