2a(1). Start with your research problem
You have done this already, for the last Task. A clear, specific research problem gives you several ways of focusing your literature search: you have a better idea of what you are looking for and you have a list of keywords to use in searching. Students who go back to look for more bibliography at the end of the semester are always surprised at how much easier it is to find relevant studies – that’s because they understand the research problem so much better.
Your formulation of the research problem specified the parts of your research problem. Use your Process, Sub-process, Factor1, Factor2, Population, and Materials use as keywords in searching. But don't start with your keywords yet! Read the other sections on planning and the sections on finding publications, first.
It is very important to note that doing a literature search will usually make you reformulate or modify your initial research problem and sometimes even change it completely. That’s normal.
