Conceptualizing researchHow do you get started/develop and idea/formulate a research plan/conceptualize and area of research?All this is really for those who wish to conduct researchFor now, Id rather focus on a framework for understanding and critiquing the research that already exists well get to the doing stage if time allows (for now, assume that the tried and tested method of asking a faculty member for a question is the best method)KNR 497FoundationsSlide 8Foundations of research
