Osel Group’s model was inspired and conceptualized from a synthesis of diverse literature, such as sustainable education, transformative learning theories, placed-based learning, indigenous learning approaches, experiential learning, eco-literacy, curriculum theory and conceptual change in science classes. Transformative processes are necessary to change the prevalent anthropocentric eco-paradigm of western culture toward more sustainable values and behaviors. “Connecting Hearts, Empowering Minds, Sustaining Humanity” – this is a holistic approach to develop ecoliteracy introduced by Orr (1992) and expanded by Sipos, Battisti and Grimm (2008). The model shows the holistic nature of transformative experience and relates the cognitive domain (Mind) to critical reflection, the affective domain (Heart) to relational knowing and the psychomotor domain to engagement (Sustaining Humanity).
