The Importance of Introductions• The Introduction• The first passage in a journal article, dissertation, or scholarly research study
that• Sets the stage for the project• Creates reader interest in the topic• Establishes the issues or concerns that leads to the study• Conveys information about the problem• Places the study within the larger context• Reaches out to a specific audience
• A Research Problem• The problem or issue that leads to the need for a study from
• Personal experience• Debate in the literature• Gaps that needs to be addressed• Policy debates• Problem in society at large
An Abstract for a StudyMost importance single paragraph in a study because:• It gives a brief summary of the contents of a study• It allows the reader to quickly survey the essential elements
of the study• It starts with the issue or problem• It indicates the purpose of the study• It states the data that will be collected to address the purpose• It indicates the themes or statistical results likely• It indicates the practical implications of the study
Qualitative, Quantitative, and Mixed Methods Introductions• Introductions take a similar pattern for all approaches, but
have some differences
• Qualitative Introductions• Problem calls for exploration• May be shaped by a theoretical lens• May be written from a personal, first-person, subjective point of view
• Quantitative Introductions• Problem calls for factors and variables• May advance a theory to be tested and substantial literature• May be written from an impersonal, objective point of view
• Mixed Methods Introductions• May use a quantitative or qualitative approach or a combination• If one approach is emphasized or begins the study, then the introduction may follow
that approach
A Model for an Introduction• The deficiencies model of an
introduction• Popular approach in research• Write one paragraph per element (2 pages total):• State the research problem• Review studies that have addressed the problem• Indicate deficiencies in the studies• Advance the significance of the study for particular audiences• State the purpose statement
See example of introduction provided on page 112-114
The Research Problem• Begin the introduction with a narrative hook to
engage the reader• Easily understood by many readers• Builds readers’ interest through reference to study
participants or posing questions• Clearly identify the issue(s) or problem(s) that lead to
a need for the study• Indicate why the problem is important by citing
numerous references
The Research Problem (cont.)• Opening sentence should stimulate interest while presenting
the issue • Do not use quotations to avoid confusion• Avoid idiomatic expressions• Consider numeric information for impact• Clearly identify the research problem• Indicate why the problem is important using the existing
literature• Frames the problem in a manner consistent with the research
approach in the study• Indicate if there is a single problem or multiple problems
involved in the proposed study
Studies Addressing the Problem• The use of literature in the introduction differs
from the full literature review (Chapter 2)• The literature review in the introduction
serves to:• Justify the importance of the problem • Set the research problem within ongoing dialogue in
the literature• Create distinctions between past studies and the
proposed study• Summarize large groups of studies (broad categories)
in the introduction instead of individual ones
Studies Addressing the Problem (cont.)Tips to consider when reviewing the literature for the introduction:• Deemphasize single studies: Summarize groups of studies not
individual ones• Use in-text referencing to remove the emphasis on any one
study• Review studies that use quantitative, qualitative and mixed-
methods approaches• Use recent studies (last 10 years) and older studies that are of
value• Summarize the more general literature and emphasize the need
for the current study
Evaluating Deficiencies in Past Literature
After addressing the problem and reviewing the literature about it, it is important to examine the deficiencies in past literature.
Deficiencies in past literature may exist because:• The topic has not been explored with a particular group,
sample, or population• The literature needs to be replicated with new people or
sites• The voice of underrepresented groups has not been
heard in published literature
Deficiencies in Past Literature (cont.)
When identifying deficiencies in past literature:• Cite several deficiencies• Identify specifically the deficiencies of the other
studies• Indicate areas overlooked by past studies
Also tell how proposed study will:• Remedy or address the deficiencies• Provide a unique contribution to the literature
Significance of a Study for Audiences
•Describe the significance of the study for select audiences to convey the importance of the study•Consider including:• 3-4 reasons the study adds to the scholarly
literature• 3-4 reasons the study helps to improve practice• 3-4 reasons the study will improve policy• End with a statement of the purpose of the study

A Quantitative or Mixed Methods Literature Review
The Literature Review
• Shares the results of other studies•Relates the study to the larger dialogue
in the literature•Provides a framework for establishing
the importance of the study•Provides a benchmark for comparing the
results to other findings
The Use of Literature• The use and length of the literature varies based
on the forum: research proposal, dissertation or journal article
• Despite this, the literature may:• Provide a summary of major studies on the research problem• Demonstrate the writers knowledge of the topic/problem/issue• Integrate what others have done and said about the
topic/problem/issue• May criticize previous scholarly works on the topic/problem/issue• May allow for connections between related topics• May elucidate the central issues in the field
Using Literature in a Qualitative Study
Using Literature in a Quantitative StudyIn quantitative studies the literature is used deductively as it provides a framework for the research questions and hypothesis–Provide direction to the research questions and
hypotheses– Introduce a problem– Introduce and describe the theory that will be used–Examine the usefulness of the theory–Compare results with existing literature or predictions
Using Literature in a Mixed Methods Study• In mixed methods studies Researchers use the
literature:– In either a quantitative or qualitative approach– In a manner consistent with either quantitative or qualitative
approach– Relative to the intended audience• Irrespective of the type of study, choose one of the
following types of literature reviews:1. Integrative2. Critical3. Building bridges among topics4. Identification of central issues
Steps in Conducting a Literature Review
• Identify key words• Search library catalogs• Identify about 50 research reports in articles or
books• Photocopy those that are central to your topic• Design a literature map• Draft summaries of the relevant articles• Write a literature review, organizing it by important
concepts
Searching Computerized Databases• Computerized databases are readily available through
libraries and the internet• These databases provide access to numerous journal
articles, conference papers and dissertations on a wealth of topics
Some of these online data bases include:- ERIC - ProQuest - EBSCO- Sociological Abstracts - PsycINFO - PubMed- Science direct - Google scholar- Social Science Citation Index (SSCI)
Searching Computerized Databases (cont.)• Use both free databases and those subscribed for by
academic libraries• Search several databases, even those outside your
field• Do not use only search terms that are identical to
your topic and study interest, slight variations in the search terms may yield more outcomes• Locate articles that are close to your topic and use
their descriptors to enhance your search• Use databases that provide access to full articles
Selecting Literature Material• Start with broad syntheses (such as
encyclopedias) if you are new to the topic• Turn to journal articles in national journals•Next consider books• Then examine conference papers• Scan for dissertations•Make sure to also review the available “grey
literature” (wealth of reports on topics related to international development on the Internet but quality varies)
Literature Map of Research•A literature map is a visual summary of
existing research on a topic• The structure of the literature map may
be:• A hierarchical pattern• A flowchart layout• A series of circles
An Example of Literature Map
Abstracting Studies• Draft abstracts that summarize selected articles• For research studies:• Mention the problem• State the central purpose• State information about the population and sample• Review key results• Point out methodological flaws (if a methodological review)
• For nonempirical studies (essays, opinions, etc.)• Mention the problem• State the central theme• State the major conclusions• Mention flaws in reasoning or logic (if a methodological review)
Style ManualsStyle manuals provide guidelines for producing scholarly work and include directions on the following:• Citing references• Creating headings• Presenting tables and figures• In-text citation/references• End-of-text references• Footnotes (not used in all style manuals)Reminder: Consistently use the chosen style manual
The Definition of Terms• Identify and define terms that readers need to
understand a proposal• Define terms introduced in all sections of the
research plan• The title of the study• The problem statement• The purpose statement• The research questions, hypotheses, or objectives• The literature review• The theory base of the study• The methods section
The Definition of Terms (cont.)• Qualitative studies are inductive and evolutionary
in nature hence the definition of terms may appear later in the written report, perhaps in the data analysis• Quantitative studies are deductive with a fixed set
of objectives, hence all relevant terms are comprehensively defined earlier in the study• In mixed methods studies the definition of relevant
terms follows the use of (earlier or later in the study) and emphasis placed on quantitative and qualitative approaches
The Definition of Terms (cont.)• Define terms when they first appear in the
manuscript• Use specific operational definitions• Do not define terms using everyday language, be
guided by the literature• Define terms so that they accomplish different
goals• One may use a definition of terms section in the
manuscript
The Definition of Terms (cont.)
A Quantitative or Mixed Methods Literature Review
• A suggested model:• Introduce the review with a statement about the
organization of the sections• Review literature about the independent variables• Review literature about the dependent variables• Review literature that relates the independent variables to
the dependent variables• Provide a summary
• Highlight important studies• Capture major themes• Suggest why more research is needed• Advance how the proposed study will fill this need
Making a Case for Your Research
1. Carefully summarize the best available literature
2. Identify deficiencies in the past literature
3. Describe how the planned study will remedy or address these deficiencies (significance of the study)
