This paper critically examines the application of research into cognitive neuroscience to educational contexts. It first considers recent warnings from within the neuroscientific community itself about the limitations of current neuroscientific knowledge and the urgent need to dispel popular "neuromyths" which have become accepted in many classrooms. It also criticises the use of over-simplified neuroscience to add scientific credibility to curricular reform, as has been the case in the rationale behind the recent implementation of the Northern Ireland Revised Curriculum. The paper then draws on the philosophy of Wittgenstein to highlight a further conceptual confusion which often surrounds the application of neuroscience to education.
