The National Student Survey (NSS) has indicated over several years that not all students in UK higher education are satisfied with the feedback they receive on their assessments. However, the Open University consistently receives high scores for student satisfaction in the area of feedback and assessment. This article provides an overview of the Open University’s model of providing written feedback on student assignments, which may be useful for other institutions. The basic model is to provide students with a sandwich in which constructive criticism is presented embedded within praise for attainment. There is also a focus on general feedback that can be applied to future assessment situations, rather than detailed corrections on assignment tasks that are not necessarily repeated.
