Writing for an Audience Who is your audience?
As for the difference between Honours/Bachelor and Masters it would depend on your university, but both have no requirement for publication quality research and are usually small tasks/ideas that are not worth the supervisors time to think about alone, or involve a lot of labor. In fact, in my school, many Honours thesis are of a higher level than the Masters, because the smart Honours students will either graduate into the work force or go straight into a PhD. The Masters students are usually those who cannot find a job and are not suited to research. However, I believe some other universities may require a mandatory Masters degree to start the PhD.
Pilot studies are tools in determining, in a preliminary fashion, the potentialities and perils of almost any research idea. For qualitative research proposals, we strongly agree with Krathwohl (1988) and Meloy (2002) that only the foolhardy begin without a pilot study that suggests how the full-blown study should be constructed. Pilot trials can sharpen the procedures, remind one of the permissions and approvals needed, assay likely costs in time, and check the feasibility of a larger study. Investment of energy in a pilot study (with advisor and committee support) can enhance the quality of a subsequent study and minimize the likelihood of unexpected delays and possible failure.
