Terms in this set (26)Classical Theory An abstract generalization that systematically explains relationships among phenomena. Descriptive Theory A theory that thoroughly
describes a phenomenon, based on rich observations of it. Grand Theory A theory that attempts to explain large aspects of human experiences. Middle-range Theory
A theory that focuses on a specific aspect of human experience (e.g., stress) Conceptual Models Deal with abstractions, assembled in a coherent scheme Framework brief explanation of a theory or those portions of a theory to be tested in a study. Theoretical Framework A theoretical framework can be viewed as the frame of a house, it is the foundation for a research study. A theoretical framework provides a rationale for predictions about the relationships among variables of a research study. It provides a context for examining a problem. Scientific Theory based on scientific inquiry. For ex, how o2 works in the body. Substantive Theory found in qualitative studies. Start to build about a certain phenomenon. Tentative Theory Begin to build on based on certain propositions Theory a set of interrelated concepts, definitions, and propositions that represent a systematic view of phenomena for the purpose of explaining and making predictions about phenomena. The overall purpose of a theory is to make scientific findings meaningful and generalizable. A theory not only guides the what of natural
phenomena but also the "why" of this occurrence. A theory is an organizing statement about abstract concepts that gives them meaning in relation to the real world. A theory represents the researcher's "best effort" to explain phenomena.

What is theoretical framework quizlet?theoretical framework. - introduces and describes the theory that explains why the research problem under study exists. - a set of interrelated concepts that symbolically represents and convey a mental image of a phenomenon.
What is the purpose of a theoretical framework in a dissertation?The theoretical framework is the “blueprint” for the entire dissertation inquiry. It serves as the guide on which to build and support your study, and also provides the structure to define how you will philosophically, epistemologically, methodologically, and analytically approach the dissertation as a whole.
