The document discusses the process of conducting a literature review for research. It begins by explaining that a literature review is an essential part of any research project that allows researchers to understand what is already known about their topic of interest. The document then outlines the steps for conducting an effective literature review, including developing keywords, searching various sources, critically evaluating existing studies, identifying gaps in knowledge, and classifying findings. It emphasizes that literature review is an iterative process of searching, reading, and refining one's understanding to identify areas for further research. The overall goal is to synthesize past work and determine what still needs to be studied.

2. You might think only dorks ‐ aka those boring academics care about research. But if even
Brad Pitt made a movie about the value of research, perhaps it’s not so nerdy at all! The
movie Moneyball which premiered 9/23/2011 is about how the manager of a losing
baseball team was able to turn things around by using the right kinds of statistical models.

3. We discussed the concept of research and its philosophical implications last class. Today,
we will discuss the process of literature review, with the important goal of developing
hypotheses or theory.

6. The literature review is more of an art than a science. Unfortunately, students tend to be
sloppy about lit review. As we will see, finding a few articles that support our point of view
is not literature review.

7. You cannot discuss or research a topic unless you know about the topic. Furthermore, in
research you must learn what is known, collectively, about the topic. Only then you can
form your own ideas and conclusions about the status of the general knowledge about this
topic.
7

8. Forming your own ideas and conclusions on the state of your topic research (e.g.
distinguishing strong studies from poor ones, noticing what is not known yet) is called a
“critical” review of the literature (and you may realized this is what you have been doing
the last couple of weeks! As a result of your literature review, you can determine for
example, after reading the available literature on this topic, that we know a lot about
college dropouts (e.g. most students drop during the freshman year) but we know very
little about why they drop . So, you find a research gap (an area we don’t know about) and
may propose filling it in with your research study!
In other words, a critical lit review helps you identify what research still needs to be done
8

9. Your literature search is usually focused on the “Secondary” category. One important
aspect to notice is that if you go to tertiary sources, the material is typically a few years old.
First, it takes a long time to do a study (ranging from 1 to 5 years) and it takes a long time
to write and publish a book (1 to 3 years). In fast‐changing fields (e.g., information
technology) the age of the source is often a critical determinant of the source’s quality,
relevance, or usefulness.
9

10. Before you start reading what has been studied about a topic, you must have an idea
where to look for theses studies; that is, you must identify your sources. In my previous
example of college dropouts, you might want to interview students who abandoned college
(in this case we say you are using primary sources), read in journals dedicated to college
education or even in newspapers about this problem (secondary sources) or look in
aggregated knowledge sources (e.g. Encyclopedias). Also, if you are lucky, you may find a
tertiary source with the title of “Handbook of College Dropout Studies” which may be an
edited book with a collection of the most relevant studies in this area. In this case you hit a
jackpot!
Now, you are beginning to understand –thanks to this course, especially Best’s book ‐ that
not because the newspaper says something, it means it is true. Even worse, the
investigative quality of the leading newspaper –lets say the “JustAfew Herald” in the town
of Justafew (I made up the name) with population of 1000 people will not be the same as
in the case of the NY Times (just a matter of resources). So, here we come to the issue of
relevance and reliability. If you are studying the problem of dropouts in that town, that
source will be relevant but if you are studying the problem at a national level you may
prefer to refer to the NY times because it is more reliable. The reliability of a source is very
arguable but typically the research community helps in this area. For example, in my own
field of management information systems, the community recognizes certain rankings as
very serious and rigorous when publishing an article. However, a word of warning.
Independently of the public perception of reliability, you must read the information
critically and make up your own conclusions whether what you read is reliable or not. The
10

11. main “take away” of this course is probably your ability to read research critically!
Finally, notice that if we use the term “college dropouts” to search for articles on this topic, I
might not get all the relevant articles or a comprehensive list. Why?... The problem of the
keywords. Perhaps the most important study on this subject had the title: “Why students fail
to complete their college education?” This means that you must generate a list of keywords
of what to look for (make sure to include “college education”). This is really more of an art –
in particular at the beginning‐ but little by little you will start noticing that certain terms
appear over and over (people love to give “names” to social problems or problems in general
(e.g. “restless leg syndrome”). So, the bottom line here is that your must generate keywords
using word associations, brainstorming, and try to be creative and open‐minded!
With respect to what search to use, it used to be that people would go to the library and use
their search tools to look for articles and books. We still do it but now we also have the
advantage of the web and search engines such as Google, which –by the way‐ has a
specialized academic search engine ( http://scholar.google.com/ ). What is the difference? All
the reference links provided are academic sources. So, this is a good search tool to use for
academic research. Unfortunately, it will provide the references in many cases but you will
still have to go to the library to read the book or article.

21. One important observation about the research review process is that it is an iterative
process. Using your original keywords you look for articles but then you read an article
which refers to another article (by the way, you must also “read” the list of references of
the articles you read) and some new terms or keywords appear so you search for related
articles again and when reading them you find that there are other terms and so on…
However, each time you should be nailing down the problem (notice that it is a converging
spiral) because you are going from the more general to the particular.
20

22. The first 4 items have been already discussed; however, it is important to address the last 2
points. The first time that students perform a literature review (I did it too as a research
methods student!) they tend to report: Study X1 found Z1, study X2 found Z2, etc. This is
just a list of references (usually commented ones). However, it is important to report
something like this: Study X1 found Z1 but because it has some serious problems (e.g.
insufficient sample size), its finding is questionable. On the other hand, the seminal study
X2 found Z2 and this finding has been corroborated by study X3, etc. This is more of a
critical review of the literature (browse the exemplary “literature review” paper ‐ Zahra
2005 Antecedents & Consequences of Top Mgt Fraud).
The previous paragraph is an oversimplification of what critical literature review is about.
You must also be able to find some sort of a classification structure for what you are
reading. For example, you could classify the studies on college dropouts in terms of studies
that deal with students’ family issues, college environment, psychological issues, etc. As
any art, the literature review is learned through trial and error and through reading other
researcher’s literature reviews.
Finally, at the end of the literature review, you must be able to state what the research gap
(this missing piece of knowledge) that you intend to fill is. Otherwise, why bother in doing
any research at all?
