From Steve Wheeler:
The most effective teachers are those who not only innovate in their practice, but also know how to justify their actions through the application of appropriate theory. Praxis is the contextualisation of theory within action. It can, and should pervade every aspect of our professional practice and identity as an educator. It’s time to stop thinking about theory and practice as separate concepts. It’s time teachers began to meld the two together, so that thinking and action – theory and practice – combine to enable us to create, develop and maintain the best possible learning environments for our students. That’s how important praxis is.
