This is based on Worley's central arguments that there are two different kinds of open and closed questions: grammatical and conceptual.
He argues that educational practitioners should be aiming for questions that are "grammatically closed, but conceptually open".
Teachers who develop an Open Questioning Mindset listen openly for the cognitive content of student's contributions and looks for ways to use what is given for learning opportunities, whether right, wrong, relevant or apparently irrelevant.
OQM encourages a style of pedagogy that values genuine enquiry in the classroom.
It provides teachers with the tools to move beyond what Worley calls 'guess what's in my head' teaching, that relies on closed and leading questions.
