This document discusses theoretical and conceptual frameworks in research. It defines a theory as a set of constructs, definitions, and propositions that explain phenomena. The theoretical framework comprises concepts and theories that guide a study. The conceptual framework provides the scope and range of a concept and discusses how theories combine. Important purposes of a conceptual framework include identifying the research problem and connecting variables to hypotheses. Key steps in constructing a conceptual framework involve examining keywords and variables, selecting an applicable theory, and describing the theory's relevance. Examples of conceptual frameworks include the IV-DV model and IPO model.
