W., (2000) indicates. The products that emerge give a summary of the progress, give directions and act as place makers. They comprise of vestiges of theories but in the real sense they are not theories on their own. The analysis of theory development done by researchers that is done through the use of graphical methods is among the most effective ways of making a quick comparison on various frameworks that have been peer-reviewed. The use of graphical models is also simple and compelling since it guides the process of theory development since its features for representing and constituting theories are meant to exemplify the actual qualities of the ideal theory. The graphical model is a natural way of lending itself towards the development of conceptualizations which are both systematic and complete. The production of a literature review is something that many researchers do not do right. Researchers can not produce good research if they are not able to understand the work that has been previously done in the same field. Lack of this prior understanding makes the researcher be disadvantaged. Therefore, doing literature review requires a good theory development since it is going to be based on work that has been done before.

Role played by theories in research articles

A good theoretical model in research articles has various characteristics. Theories have to give a meaning, they should also enable people understand and make an interpretation of data. The theories give a specification of the important variables and give a reason for this. They also give an explanation and description of relationships which give a link to the variables. They also identify the existing boundary conditions under which variables are supposed to or not supposed to be related. Theories also help in the identification and definition of problems, give a prescription of solving the problem and lead to the facilitation of the problem responses. They also allow the generalization that goes beyond the sample that is immediate and at the same time make it possible to make predictions. Any research article that is written...

When it comes to reading, good theory leads to the development of a sense of illumination and discovery. Good theory leads to creation of clear and coherent world processes through the simplification and structuring their understanding. Basically in research articles theories can be used in designing of research questions, give a guide for the selection of data which is relevant, interpretation of data and finally give propositions to explanations of causes which that are underlying or have an influence on the phenomena that has been observed.
Conclusion

Theory development is very important in any research article .this means that any research that is done should always encompass the development of theory if researchers want to successfully carry out the research. This should hence be embraced by all researchers and be part and parcel of every research article.
