Print: Our self-study workbooks (called 'Study Units') are the main teaching vehicle for an Open University course. Their unique features include a clear structure to take students step-by-step through to specific learning tasks, easily digestible modules, each with clear learning objectives and self-assessment questions and activities with model answers, to engage the student in active learning. We also include details of our co-published books within the 'Print' category. Co-published books are created by The Open University and commercial publishers, for sale to audiences worldwide.
