When I had to write mine I looked at endless samples and examples of research proposals. Pity I forgot to pay close attention to what my supervisor really expected! It's so important to have regular meetings and check your work is going along the right lines, from the start.
Some of the sources where you may find examples of research proposals to give you an idea on how to develop your research proposal in an effective manner are given below:
An Example of a Research Proposal - University of Hull
Authored by international scholars of qualitative nursing research, the book elucidates the theoretical rationale for using phenomenology, describes its components, and delineates a plan to conduct studies that includes appropriate methods, ethical considerations, and potential pitfalls. The book provides guidance for writing a research proposal that justifies the importance or potential impact of a study and describes how to conduct interviews that best elicit information. It focuses on achieving rigor in phenomenological research in regard to accuracy and replicability, and discusses different types of data collection and analysis and when to use them. Each chapter provides objectives, competencies, review questions, critical thinking exercises, and links to web resources. Appendices include a list of qualitative research journals, textbooks, and other resources for more in-depth study as well as examples of research proposals and interviewing techniques. The book will be of value to novice and experienced nurse researchers, graduate teachers and students, in-service educators and students, and nursing research staff at health care institutions.
