Conducting a literature review is a mean sof demonstrating an authors knowledge about a particularly field of study including vocabulary theories, key variables and phenomena and its methods and history.
Gall (1996) finds that Literature Reviews plays a part in:
- Delimiting the research problem
- Seek new lines of enquiry
- Avoiding fruitless approach
- Gaining Methodogical insights
- Identifying Recommendations for Future Research.
- Seeking Support for ground theory.
Literature Reviews also provide opportunities to distinguish betwen what has been done and what needs to be done. Without establishing what the previous research has been undertaken, it is impossible to establish how future research will enhance that research undertaken previous.
Literature Reviews are a means of analysing and synthesizing previous study into an area and more than just a bibliography of previous research. Literature Reviews provide the opportunity to summarise the literature and drawing conclusions on this.
Cooper’s Taxomony of a Literature Review:
Literature Reviews can be classified according to these categories:
- Focus.
- Goal
- Perspective
- Coverage
- Organization
- Audience.
Focus:
Two main outcomes exist: Outcome option may deal with theories related to phenomonem being investigated and introduce the practice. Methodolgical reviews help identify the methodological weakenesses and strengths of a certain body of research.
Goal
The goal of many literatrure review is to integrate and generlize findings across:
- Units
- Treatments
- Outcomes
- Settings.
Literature Reviews can be either Methodogical Based or Outcomes Oriented –The technique of metaanlysis is used in Literature Reviews with the goal of integrating quantitative outcomes across studies. Critical Analysis as a technique can be used to explain an argument within a field.
Perspective
There are two perspectives that a literature review can take:
- Qualititative Primary Research – Where the author takes on the perspective to reveal their own pre-existing review and biases which can impact the review.
- Quantitative Primary Research: - Where the authors can attempt to take a neutral perspective and present the findings as fact.
Coverage
Cooper proposes 4 possible scenarios:
- Exhaustive Review- The author promises to locate and consider every piece of research on a certain topic.
- Exhaustive Review – Selection Criteria – where you define the population in such a way that is bounded (an example could be just using journal articles.
- Representative Sample – Review sample of articles and make inferences about, random sampling.
- Purposeful Sample: - Examines only the central protocol. In this scenario, the goal is to convince the reader that the sample is pivotal to their understanding.
Organization
Literature Reviews can take various forms. The most common include:
- Historical format
Working chronologically = common when looking a progression of research or theories over a period of time.
- Conceptual format
Organized relating to concepts.
- Methodogical format.
Generally organized with introduction, method results and discussion.
It is possible to include a combination of a variety of these in order to be most effective (eg mix and match the formats)
Audience
The primary audience for most literature reviews are generally a supervisor.
The secondary audience are generally peers.
It is important to remember to avoid writing the review in a non academic format.
How to write a literature review.
Cooper (1984) Describes the stages of conducting a literature review:
- Problem Formulation.
- Data collection.
- Data Evaluation.
- Analysis and Interpretation.
- Public Presentation.
Problem Formulation
Formulating the question is the first step after deciding on the format of the review. There are two types of questions:
Literature Review Question – Which are those which can only be answered through reviewing the secondary research.
Empirical Research Question - those which can only be answered through reviewing primary research.
Questions can be:
- Critical Analysis.
- Integrate Research Outcomes.
- Focus on past themes.
Data Collection
Collection can be either exhaustive, semi exhaustive representative or pivotal set of relevant articles. The reviewer is advised to describe their data collection method. Using reference lists of the research being reviewed is a source of finding research.
The data collection process can stop when the point of saturation (eg all the articles meeting the criteria) is reached.
Careful identification of the types of data which is to be included / excluded at the commencement of the research review will assist with this process. The exclusion process will continue throughout the collection process.
Data Evaluation
At this stage the reviewer begins to extract and evaluate those which meet the criteria for inclusion. The reviewer needs to come up with a strategy for extracting data, of which the data is determined by the focus and goal of the review.
Data Analysis / Evaluation
The reviewer at this stage attempts to mae sense of the data which ha sbeen extracted. Depending on the type of data extracted, a quantitative, qualitative or mixed method synthesis will be performed.
Public Presentation
At this stage, the reviewer needs to determine which information is most important and what will be presented in the review and what will not.
My personal overview of the article.
This article provided a really good description of the stages involved in the planning and structure of the Literature Review. The article will assist in the development of my literature review, particularly with the importance of planning the structure and what should / should not be excluded
