Literature Review

2.1 Why is a review of literature important?

LITERATURE REVIEW

Literature review is a thorough investigation and assessment of the literature in researcher’s given subject or chosen topic area. It puts together the state of the art with respect to the subject or topic the researcher is writing about. It provides the researcher with the information on what other researchers conducted in relation to the topic or study area being investigated so that he/she would be able to have better understanding of the topic and be in a position to explain the findings. Literature review can work in both new topic, that is an original topic that was never reviewed and existing topic. To support this, Toroco (2016:409) says that, “most integrative literature reviews address two general kinds of topics – mature topic or new emerging topics. This is because social and behavioral science topics vary along an age continuum from old to new. Because features of a literature review differ depending on the maturity of the topic reviewed”.

Literature review is a base for a researcher to develop problem statement based on his or her knowledge about the chosen area of study, personal experience about the topic in question as well as the supporting documents that is available literature. According to STUDY MATERIAL (), when a researcher is about to start a particular study it makes sense for him/her to know what other researchers around the world have been with respect to the same topic”. In this way the researcher will be able to provide answers to the formulated question.

By identified the problem in the study through literature review shows that the researcher would be able to state the question in such a way that the solution to the problems would be understood by the audience.In that way literature review gives direction to for both theory and method thereby improving the quality and usefulness of the research being conducted.The researcher while reviewing the study should bear in mind that the study is done to convince the people that are in a position to implement the conclusion the study may come up with.

Considering the third party and convince them about the discrepancy or what lacks to the existing or previous study

THE OBJECTIVES/GOALS/PURPOSES OF A LITERATURE REVIEW

According to the STUDY MATERIAL (35) the purpose of literature review is to share the findings of the research with others and in that way, add to the existing body of scientific knowledge. That is to establish what are the already existing studies, how those relate to each other, to what extend the existing study have been investigated and then develop new study.Thus research contributes to the understanding of the world around us”. To add more on this Toroco (2016:411) identified five goals and purposes of integrative literature review and those are: (a) review, update and critique the literature review; (b) conduct meta-analysis of the literature review(c) review critique, and synthesize the literature (d) conceptualize the topic reviewed in the literature (e) answer a specific question about the topic reviewed in the literature.

Literature review improve the value and quality of knowledge on the study being reviewed and it can be shown by providing critical analysis on how well the study is presented in already existing study. Toroco (2016:411) called this purpose a “review, update and critique of the literature. According to him literature reviews are expected to enhance knowledge on the topic beyond what is contained in the original literature sources……critical analysis of the literature identifies its strengths and weaknesses as well as any deficiencies or contradictions among literature review.

Find out what information already exist in the field of research

It is imprtant that before taking any step of reseach to review the field, this show the researcher does not only know the work in his or her field he/she knows how to access information around it
