Optimising student learning is an important goal of Christian education. It is suggested the strongest contribution teachers can make to improving student learning is to adopt a research-evidence based teaching system (The Gonski 2.0 Review, cited in Ballantyne, 2018a). In particular: Pedagogical practices must be contemporary and evidence-based, and teachers must have the resources and expertise to update their methods to those practices proven effective by current research. … Crucially, schools need to help teachers seize any opportunity to work collaboratively and review their own teaching practices.
