Document Summary
Sources of research ideas: two approaches to theory, deductive processes. Involved reasoning from the general to the particular. Begins with specifics and uses these to generate general: inductive processes principles. Move from observation to theory: wallace inductive and deductive approaches are not in either/or opposition, but rather are better seen as opposite sides of the same coin. Wallace"s wheel infinite process that encompasses both deductive and inductive methods. Offers an important representation of the scientific process: deductive sources of research ideas, theory as a source of research ideas. A theory is essentially a set of concepts and a delineation of their interrelationships that, taken together, purport to explain a phenomenon or set of phenomena. An important dimension on which theories vary is in their prospective comprehensiveness. Good theories are useful devices because they help coordinate research b providing a research focus and by implying hypotheses that can be tested empirically.
