Should teachers use external research to influence their practice or use their practice to answer their research questions?

Whitehead’s Living Educational Theory is a form of self-study that is focused on the researcher aiming to develop their own teaching practice. “A Living Theory researcher recognizes that there is no existing methodology that is appropriate for exploring the implications of asking, researching and answering the question, ‘How do I improve what I am doing?’” (Whitehead, J, 1979).
