1、Developing the theoretical and conceptual frameworkJ199 lecture,R.E.KhanTheoryTheories are constructed in order to explain,predict and master phenomena(e.g.relationships,events,or the behavior).In many instances we are constructing models of reality.A theory makes generalizations about observations

2、and consists of an interrelated,coherent set of ideas and models.Formulating the Theoretical FrameworkThe theoretical framework of the study is a structure that can hold or support a theory of a research work.It presents the theory which explains why the problem under study exists.Thus,the theoretic

3、al framework is but a theory that serves as a basis for conducting research.Formulating the Theoretical FrameworkPurpose:It helps the researcher see clearly the variables of the study;It can provide him with a general framework for data analysis;It is essential in preparing a research proposal using

4、 descriptive and experimental methods.For example:Media Organization,Selection,and Production.McQuails theory on media as an institution takes into account all forces that affect medias performance.(After:Littlejohn,1992)Basic theory 1Thesis examines the gatekeeping,news selection and reportage of w

9、mework,the researcher has to develop the conceptual framework of the study.A concept is an image or symbolic representation of an abstract idea.Chinn and Kramer(1999)define a concept as a“complex mental formulation of experience”.While the theoretical framework is the theory on which the study is ba

10、sed,the conceptual framework is the operationalization of the theory.Conceptual frameworkIt is the researchers own position on the problem and gives direction to the study.It may be an adaptation of a model used in a previous study,with modifications to suit the inquiry.Aside from showing the direct

11、ion of the study,through the conceptual framework,the researcher can be able to show the relationships of the different constructs that he wants to investigate.Conceptual Framework.News values,and the pressures and constraints shape the newspapers and television newscasts.The result of this relation

15、h problem through the proposed framework.Research design depends on the nature of the data to analyzed.Quantitative data when your thesis problem requires numerical measurements of traits,trends,characteristics or attributes of the subject matter;Analysis leads researcher to:depict what is typical a

16、nd atypical among the data;show the degree of difference or relationship between two or more variables;determine the likelihood that the findings are real for the population as opposed to having occurred only by chance in the sample.Qualitative data when your thesis problem focuses on the meanings,perceptions,symbols or description of the subject matter.Analysis leads researcher to:observe behaviors,situations,interactions and environments;scrutinize these observations for patterns and categories;answer research questions based on what can be deduced from the findings.
