holistic yet tangible - Embracing the Challenge of Complexity for Education for Sustainable Development

UNESCO defines education for sustainable development (ESD) as addressing a broad range of issues, from natural resources and HIV/AIDS to poverty reduction, requiring a stance that is subtle yet clear and holistic yet tangible. The text argues that ESD can respond to complexity either by simplifying and narrowing issues or, more viably, by retaining breadth while unifying epistemologies. It proposes an ecosemiotic view of human–nature knowledge relations and a pragmatic approach for making value judgments to guide curricula.

“holistic yet tangible”: Embracing the Challenge of Complexity for Education for Sustainable Development Patrick Hanley Harvard University The possibility of a sustainability transition becomes actual when mediated by and through ecosemiotics. Max Oelschlaeger (in Noth and Kull, 2001, p. 232) Abstract UNESCO defines education for sustainable development (ESD) as covering a broad range of issues from natural resources and HIV/AIDS to poverty reduction. ESD thus becomes a term that must be subtle yet clear, holistic yet tangible. One option for ESD, in dealing with this complexity, is to simplify its content and narrow the issues it addresses. Another more viable option for ESD is to retain a broad range of issues and related domains of knowledge while unifying the range of epistemologies it employs. The challenge then is to agree on an epistemology that is inclusive of all domains of knowledge while being practical for education initiatives in the field. This article will examine the utility of an ecosemiotic conception of the epistemological relationship between humans and nature (how we conceive of how we come to knowledge about nature), and a pragmatic method of making value judgments in helping ESD meet the challenges of complexity Introduction UNESCO’s Draft International Implementation Scheme for the United Nations Decade of Education for Sustainable Development recognizes the need for education for sustainable development (ESD) to cover a broad range of issues from natural resources, HIV/AIDS to poverty reduction (UNESCO, 2004, p. 5) . Covering such a range of issues will require a wide range of fields of knowledge, from the physical and social sciences to religion and local mythology. It is written in UNESCO’s Draft International Implementation Scheme: No aspect of life is left untouched by the pursuit of sustainable development, just as development that is increasingly sustainable will have an impact in every part of life. Complexity and interconnectedness mean that ESD must convey messages that are subtle yet clear, holistic yet tangible, multi-dimensional yet direct (UNESCO, 2004, p. 13) . ESD curricula cannot concentrate only on one dimension, such as science in exclusion of religious beliefs, or global knowledge in exclusion of local knowledge, or vice versa. To succeed, ESD cannot afford to ignore, consciously or sub-consciously, any aspect of human culture no matter how“superfluous” or how“outright false” others may consider them (Patton, 1996, p. 82) . But by aiming to be multi-dimensional and holistic, ESD risks being too cumbersome to work fluidly in the field and risks not being clear, tangible and direct. © 2005 Current Issues in Comparative Education, Teachers College, Columbia University, ALL RIGHTS RESERVED Current Issues in Comparative Education, Vol. 7(2) 85 Patrick Hanley One option for ESD is to simplify its content and narrow the issues it addresses, but this would undermine the far-ranging goals of sustainable development. ESD needs to work with the complexity of human culture, rather than try to confront it or tame it. Another option is for ESD to retain a broad range of issues and related domains of knowledge while unifying the range of epistemologies it employs. A difficulty with a wide range of domains of knowledge is the difference in theories of knowledge and meaning-making inherent in each domain. The challenge is to develop epistemologies that are inclusive of all domains of knowledge while being practical for the creation of curricula in the field. Curricula are based implicitly or explicitly on theories of how we gain knowledge about the world and how to make judgments about meaning or value. The exact theories of knowledge and value judgment on which an education initiative is based will have a strong influence on what is taught and what is learned. To begin a dialogue this article will offer one perspective on the utility of an ecosemiotic conception of the ep

FAQs

Why does UNESCO’s broad definition of ESD make clarity and subtlety both necessary?

Because UNESCO’s ESD spans many issues, the article argues ESD must communicate messages that are subtle yet clear and holistic yet tangible to handle complexity and interconnectedness.

What does the article suggest as the more viable approach to ESD curriculum design?

It recommends retaining a broad range of issues and related knowledge domains while unifying the epistemologies used, rather than simplifying content and narrowing issues.

How does the article connect ecosemiotics to ESD’s educational challenge?

It proposes examining an ecosemiotic conception of how humans relate to nature in forming knowledge, and then using a pragmatic method for making value judgments so ESD can address complexity in education initiatives.
