2. Review of Literature
Content: This section discusses the theoretical
foundations of the problem.
The goal: is to develop your problem
conceptually and place it in the context of
previous scientific work.
Thus, a conceptual integration of previous
research is needed. Point out the themes, link,
gaps, and inconsistencies in the literature with the
aim to provide a clear conceptualization of the
problem.
Note that it is NOT the purpose of this section to
display how much literature you have read.
Avoid presenting a litany of past studies that are
conceptually disconnected from each other.
3. Review of Literature
This section provides justification of your
problem and hypothesis:
Why study these particular variables?
Why propose these particular hypotheses?
Why study the problem with this method?
What differentiates your approach from
what has been previously done?
4. Review of Literature
Format: Unlike other sections in Chapter I,
this section is written in the past tense.
Begin this section with a heading (bold,
centered, upper- and lowercase).
To enhance organization, use subheadings.
5. Types of Literature
1. Conceptual Literature
2. Research Literature
Note: Researchers undertake a literature
review to familiarize themselves with the
knowledge base.
6. Purposes of Literature Review
1. Identification of a research problem and
development or refinement of research
questions or hypotheses
2. Orientation to what is known and not
known about an area of inquiry, to
ascertain what research can best make a
contribution to the existing base of
evidence
7. Purposes of Literature Review
3. Determination of any gaps or
inconsistencies in a body of research
4. Determination of a need to replicate a
prior study in a different setting or with a
different study population
5. Identification or development of new or
refined clinical interventions to test
through empirical research
8. Purposes of Literature Review
6. Identification of relevant theoretical or
conceptual frameworks for a research
problem
7. Identification of suitable designs and data
collection methods for a study
8. For those developing research proposals
for funding, identification of experts in the
field who could be used as consultants
9. Purposes of Literature Review
9. Assistance in interpreting study findings
and in developing implications and
recommendations
10. Scope of a Literature Search
1.Types of Information to Seek:
Primary source research reports -
descriptions of studies written by the
researchers who conducted them
Secondary source research reports -
descriptions of studies prepared by
someone other than the original researcher
11. Scope of a Literature Search
2. Depth and Breadth of Literature
Coverage
A review included in a research report.
A review included in a research proposal.
A review in a thesis or dissertation.
Free-standing literature review.

- are reports that summarize a study or
one aspect of a complex study.

method section, results section, discussion
section, plus an abstract and references.
20. Flow of tasks in a literature
review
1. Identify key words and key concepts to be
searched
2. Identify potential references through
electronic or manual search
3. Retrieve promising references

6. Identify new references through citations
7. Organize references
8. Analyze and integrate materials
9. Write review
22. 5 Parts of Review Literature Review
1. The introduction: state the nature of the
research problem and states the research question
2. The body: reports what others have found or
thought about the research problem.
- Related study are usually discussed in group under
subheads (to make the review easier to read)
- Major studies described in more details, while less
important work can be referred to in just a line or
two
23. 5 Parts of Review Literature Review
2. The body:
- Referring to several studies that reported
similar results in a single sentence,
somewhat like this;
- Ex. Several other small-scale studies
reported similar results (Adams, 1976;
Brown, 1980; Cartright, 1981; Davis, 1985;
Frost, 1987)
24. 5 Parts of Review Literature Review
3. The summary: ties together the main
threads revealed in the literature reviewed
- Presents a composite picture of what is known or
thought to date
- Give readers some idea how many other
researchers have reported identical or similar
findings or have similar recommendations.
4. Any conclusions:
25. 5 Parts of Review Literature Review
4. Any conclusions: the researcher feels
justified based on the state of knowledge
revealed in the literature should be
included.
5. A Bibliography: a full bibliographic data
for all sources mentioned in the review is
essential.
