In 1987, a team of three people – David Wade Chambers, David Turnbull and Helen Watson Verran – began a systematic review of cross-cultural content found in teaching materials in the History, Philosophy and Social Studies of Science. In this book, one of several publications resulting from that collaborative scholarship, Watson Verran (with the Yolgnu community at Yirrkala) and Chambers examine and compare Indigenous and European ways of understanding nature in Australia. This website is a transcription of the book.
