A good literature review should critically evaluate previous research rather than simply summarise previous work.
The author needs to point out the shortcomings of the previous work in order to demonstrate that your study is worthy of further research and study.
At the end of the literature review, the writer also needs to state that your study is unique and that no literature directly addresses the issue. Explain the importance of your study and its value to the body of knowledge in your field.
Structure of a literature review
Introduction.
● Define the TOPIC, well provide an appropriate context for reviewing the literature
●Establish your rationale (placebo-literature review.)
●Explain the organisation (order) of this section.
● Explain the scope of the literature review, i.e. what is included and what is not.
For example, if you are reviewing the literature on childhood obesity. You might say something like this There are a large number of studies on obesity trends in the general population. However. Since this study focuses on childhood obesity, this literature will not be examined in detail.
Main body.
● organise and critically analyse the literature according to common themes
● Provide insights into the relationship between your chosen topic and the wider E topic area, e.g. the relationship between childhood obesity and obesity in general:
● Provide insights into the relationship between childhood obesity and obesity in general.
● Move from the general. broader perspective of the literature review to the specific focus of your research.
Conclusion.
● Summarise important aspects of the existing body of literature.
● Evaluate the current state of the literature review.
● Identify significant gaps or gaps in existing knowledge.
● Understate the scope of future research.
● Relate your research to existing knowledge.
Key points in writing a literature review.
● It is not a descriptive list.
It is not a summary of book after book, article after article.
It is not a survey of everything written about your topic.
● It must be defined by a guiding concept. That is, the problem or research objective that the paper will examine.
● It must tell the reader what knowledge and ideas have been established and developed in your field of study and outline their strengths and weaknesses .
