Transdisciplinary Approach to Language Study argues that scientific research should aim to help find solutions to the real-life problems of real people. It promotes a new model of constructivist knowledge creation in the area of language study, based on concepts of complexity theory with a strong transdisciplinary aspect. The study focuses on examples of scientific approaches and research methods in the study of language and society which foster a dialogue among academic communities, policy makers and interested non-scientific communities of practice. The book argues this is necessary in order to come up with long-term, sustainable solutions which may ultimately lead to a more equal distribution of social power in our societies.
