Reflecting through the prisms of past, present ("the shape of things that are and were") and future ("the shape of things to come"), this paper discusses three challenges for sociology of education: the rise of populism and declining faith in 'experts'; inequities within and re/produced by the sociology of education; and how to enact a sociology of education that can 'make a difference' to social inequalities. The paper puts forward some ideas in support of a current and future practice of the discipline that is pluralistic and orientated towards social justice. Arguments are made for the value of public-orientated dialogue that is conducted in a range of registers and the importance of acknowledging and engaging with the 'debt' (Ladson-Billings) that is owed to minoritized communities and minoritized researchers. Finally, a case is made for a sociology of education based on the principle of service as enacted through praxis partnerships. [ABSTRACT FROM AUTHOR]
