This article, based on research conducted by the National Foundation for Educational Research (NFER) for the UK branch of the European Space Education Resource Office (ESERO-UK), also known as the UK Space Education Office, sets out how one school has taken a highly collaborative approach to delivering this course, working alongside university and industry partners to develop an interactive and varied curriculum for a group of female students.
