Book excerpt: The methodological explorations offered in this book (and indeed the book series) enable considerations of how research practices have profound implications for the purpose and nature of education. Methodological complexity and context specificity, along with a need to ensure research participant consideration, are revealed through thirteen chapters. These considerations continue to change the landscape of educational research, particularly in the areas of mathematics, health and environmental education research. The authors featured in this volume think critically about education research design and practice as part of a considered and robust discussion of education research theory and practice that will inform and shape education systems in the future. Chapters explore co-design with teachers, researching for system change, the ethics of ‘netnography’, principles and practices of literature review, and post-qualitative inquiry, with overviews and practices, arts-based and interdisciplinary methodologies, self-study and auto-ethnography.
