This brief module is designed primarily for students who will be developing questionnaires for their own research. It provides a series of tips and briefly explains how they can guide a student in designing an effective questionnaire. This resource has been created within the Open Educational Resources project "Evaluating the Practice of Opening up Resources for Learning and Teaching in the Social Sciences" [C-SAP OER], undertaken by the Subject Centre for Sociology, Anthropology and Politics based at University of Birmingham, for further information see here: http://www.c-sap.bham.ac.uk/subject_areas/elearning/oer/default.htm. The project is part of UK-wide Open Educational Resources programme [UKOER]. Within the programme, JISC (Joint Information Systems Committee) and the Higher Education Academy are collaborating with the aim of enabling higher education institutions, consortia and individuals to share learning materials freely online. The programme supports universities and colleges in exploring processes and policies, intellectual property rights, cultural issues, technical requirements and data management issues.
