Book excerpt: Through a range of unconventional genres, representations of data, and dialogic, reflective narratives alongside more traditional academic genres, this book engages with contexts of decoloniality and border thinking in the Global South. It addresses processes of knowledge production and participation in the highly divided and unequal schooling and higher education system in South Africa, and highlights the consequences of the monolingual myth in post-colonial education, demonstrating opportunities for learning provided by translanguaging. It explores both embodied, multimodal and multilingual instances of knowledge-making in teaching and teacher education that take place outside but alongside formal classroom, lecture and seminar modes, and the positionality and learning experiences of teacher educators in science, literacy and language across the curriculum. The book is not only transdisciplinary but also captures the learning that takes place beyond the borders of disciplines and formal classroom spaces.
