Renolds (2007) takes us through the journey of translating an idea to a potential scientific knowledge. The purpose of scientific knowledge includes providing typology of objects of study, prediction of future events, explanation of past events, sense of understanding of causes of events, and the potential for control of events. In order to achieve the above purpose, a researcher makes claims or ‘theories’ by extracting statements from a conceptual model describing characteristics or concepts of object of study. Conceptualization could take the form of Kuhn paradigms (i.e. views that radically depart from held beliefs), paradigms (i.e. views that represent dramatic new orientation), or paradigm variations. Concepts are essential ingredients of theoretical statements and their definition must be acceptable to relevant scientists. Not necessary as in some social science studies, it is important that concepts or surrogate concepts in statements be quantifiable either at nominal, ordinal, interval, or ratio level.
Statements might describe an existence of a phenomenon (i.e. existence statements) or relationships between concepts (i.e. relational statements) in theoretical, operational, or concrete abstraction level. Theoretical statements (which more abstract than operational and concrete statements) form the most important element of a scientific body of knowledge.
These statements could be laws (i.e. ‘real truth’), axioms (i.e. basic statements), propositions (i.e. statements derived from axioms), or hypothesis (i.e. untested statements). Hypothesis statements might be derived from variations of laws, axioms, propositions, or all. They must be falsify by testing them against real life or empirical data. Concepts in hypotheses "must be measurable using appropriate operational definitions in a concrete setting" (Renolds, (2007), p. 80).
When measuring concepts in human and social science phenomenon, it is important to measure phenomenon unobstructed by avoiding ‘fight-back’ or ‘learning’ effect, to maintain objective or value-free orientation by stating any bias upfront, and to uphold ethical codes of research.
I appreciate Renolds’s theory construction primer. I will reread it but here are my questions:
(1) Renolds talks about not making scientific contribution if the object of study is situated in temporal or spatial context (Reynolds, 2007, p.12 & 13). He exempts those that are significant enough and categorizes them as historical explanations. These historical explanations are accepted if they reinforce an underlying general principle being applied. How about case studies situated in temporal or spatial context with no apparent support or test of explicit general principles?
(2) Is it acceptable at this level to make claims that tend to explain associations but do not explicitly indicate independent and dependent variables (Reynolds, 2007, p.70 & 71)?
