consideration should be given to
Consideration should be given to..
  • Provenance- author’s credentials
  • Objectivity
  • Persuasiveness
  • Value
purpose of lit review
Purpose of Lit. Review
  • Place each work in the context of its contribution to the understanding of the subject under review
  • Describe the relationship of each work to others
  • Identify new ways to interpret, and shed light on any gaps
  • Resolve conflicts
  • Point the way forward for further research
why do we need good lit review
Why do we need good lit. review?
  • To demonstrate that you know the field.
  • To justify the reason for your research
  • To allow you to establish your theoretical framework and methodological focus
starting point
Starting point..
  • Pursue recent review articles
    • Too much to handle
    • Very little there
      • Doing something new
      • Limiting yourself to too narrow an area
      • Not a worthwhile area of research
quality of literature
Quality of Literature
  • Is the problem clearly spelled out?
  • Are the results presented new?
  • Was the research influential?
  • How large a sample was used?
  • How convincing is the argument made?
  • How were the results analyzed?
  • What perspective are they coming from?
  • Are the generalizations justified by the evidence on which they are made?
  • What is the significance of this research?
  • What are the assumptions behind the research?
  • Is the methodology well justified as the most appropriate to study the problem?
  • Is the theoretical basis transparent?

In critically evaluating, you are looking for :

(i) Strengths, significance and contributions

(ii) Limitations, flaws and weaknesses

(iii) Whole lines of enquiry

Simple way to do lit. review
  • Start with a series of paragraphs???
      • “Green (1975) discovered….”;
      • “In 1978, Black conducted experiments and discovered that …”;
      • “Later Brown (1980) illustrated this in ….”
  • NO!!! This demonstrates neither your understanding of the literature nor your ability to evaluate other people’s work
this way is better
This way is better…..
  • “There seems to be general agreement on x, (for example, White 1987, Brown 1980, Black 1978, Green 1975) but Green (1975) sees x as a consequence of y, while Black (1978) puts x and y as having no effects on one another. While Green’s work has some limitations in that it…, its main value lies in….”
  • This shows that you have thought about it, can synthesize the work and pass judgement on the relative merits of research conducted in your field

  • Ask yourself questions like these:
    • What is the specific thesis, problem, or research question that my literature review helps to define?
    • What type of literature review am I conducting?
    • What is the scope of my literature review?
    • How good was my information seeking?
    • Have I critically analyzed the literature I use?
    • Have I cited and discussed studies contrary to my perspective?
    • Will the reader find my literature review relevant, appropriate and useful?
