What is the Literature Review? The ‘finished product’
i.e. chapter(s) in your dissertation Extensive reference to relevant research in your
area Sets the scene for why you do the things you did
in the way you did them

What is the Literature Review? The ‘process’
Conducting a review of the literature Ongoing activity not just at start of the research
process Helps formulate your research question Helps identify approaches or experimentation Later helps with analysis and evaluation

Why do I need a Literature review?(Process)
Finding out what is happening in your area of research is a vital step along your journey to discovery,
to find and understand how leading researchers in your field have tackled similar problems and the results they obtained, shortcomings they observed and methodologies they employed
= goals of the literature review process.
![Page 5: Literature Review](https://reader035.vdocument.in/reader035/viewer/2022062814/568167e2550346895ddd483d/html5/thumbnails/5.jpg)
Why do I need a literature review?(Product) It shares with the reader with other studies closely
related to your work It relates your work to the larger, ongoing dialogue in
the literature It introduces terminology and definitions to clarify
how terms are being used in the context of your work It shows how your study is filling in gaps and
extending prior studies It provides a framework for establishing the
importance of your study It provides a benchmark for comparing the results of
your study with other findings

2D Analysis The objective of this process is to
systematically analyse the existing research and classify it in one of two dimensions.
The breadth of the review is concerned with ‘setting the scene’, in terms of describing the foundational research in this particular domain, there will be research mentioned from each of the areas you have included in your spider diagram.
The depth of the research concerns itself with the particular topic work that your research will be built upon. There should be approximately the same number of research papers covered in the depth and breath of the research review.

The Literature Review To made things clear, we divide the Literature
Review into three parts:
LiteratureSurvey
LiteratureComprehension
LiteratureReview
Collecting the literature
Understandingthe literature
Reviewing the literature

The Literature Survey/Search
‘a systematic and thorough search of all types of published literature in order to identify as many items as possible that are relevant to a particular topic’Gash, S. (2000) Effective Literature Searching for Research 2nd Ed., Aldershot: Gower Publishing Ltd.
![Page 14: Literature Review](https://reader035.vdocument.in/reader035/viewer/2022062814/568167e2550346895ddd483d/html5/thumbnails/14.jpg)
Literature Survey Identifying and acquiring
the research papers, textbooks, web-sites, theses, etc.
to get a comprehensive overview of the research that has been done in the area that you are investigating.
![Page 15: Literature Review](https://reader035.vdocument.in/reader035/viewer/2022062814/568167e2550346895ddd483d/html5/thumbnails/15.jpg)
Literature Survey A focused survey technique is recommended
to ensure you ‘hit the ground running’ If you know the exact domain of your research
it makes sense to initially focus your search on papers that relate (almost) exactly to your own research, rather than spending a great deal of time reading every paper under the sun that seems remotely relevant.
Recording the sources you have found and read is also of vital importance
![Page 16: Literature Review](https://reader035.vdocument.in/reader035/viewer/2022062814/568167e2550346895ddd483d/html5/thumbnails/16.jpg)
Literature Survey
Recording the sources you have found and read is also of vital importance, and techniques and software available for these tasks are also covered in this section.
If you know the exact domain of your research it makes sense to initially focus your search on papers that relate (almost) exactly to your own research, rather than spending a great deal of time reading every paper under the sun that seems remotely relevant.

Literature Survey
A vital step is to identify
KEYWORDS
![Page 20: Literature Review](https://reader035.vdocument.in/reader035/viewer/2022062814/568167e2550346895ddd483d/html5/thumbnails/20.jpg)
Literature Survey Using these keywords, go to the library and go
online and look for journal papers, books, conference papers, etc. that are relevant.
Just using Google is insufficient, you need to search in the real world as well.
![Page 21: Literature Review](https://reader035.vdocument.in/reader035/viewer/2022062814/568167e2550346895ddd483d/html5/thumbnails/21.jpg)
Literature Survey e.g. you are doing research on Communities
of practice What other keywords do we need to look out
for? Network of practice Virtual community Virtual Ethnography Virtual team Community-driven knowledge management
![Page 22: Literature Review](https://reader035.vdocument.in/reader035/viewer/2022062814/568167e2550346895ddd483d/html5/thumbnails/22.jpg)
Literature Survey If you are doing research on one of the
following Cloud Computing Knowledge Sharing Usability Data Quality
What other keywords do we need to look out for?
![Page 23: Literature Review](https://reader035.vdocument.in/reader035/viewer/2022062814/568167e2550346895ddd483d/html5/thumbnails/23.jpg)
Literature Survey You need to get a
notebook/create an electronic artefact you can access constantly and list all the keywords in there.
Use that to record ideas you have about your research.
Use it to record details of meetings with your supervisor.
Insert any useful newspaper articles, pictures, etc. that help.

Snowball Technique As you read you will redefine your focus
through searches You will become familiar with authors and
texts commonly cited and start to look for specific papers
Snowball technique is when you follow up references from bibliographies of texts you read
Keep a record

Literature Survey What does peer-reviewed mean?
When you submit a research paper, a number of people will read the paper and give feedback/corrections on it.
The people who review it will be as expert as you are in the field of research (and as such are your peers).
Some conferences only get one person to review a paper, others get two, others more – the more people that review conference papers, the more prestigious the conference is, since the papers in it are bound to be of very quality.
Journal papers are normally reviewed by several people, and are considered very credible.

Who are ACM ? The Association for Computing Machinery, or ACM,
is a learned society for computing. It was founded in 1947 as the world's first scientific
and educational computing society. Its membership is more than 92,000 as of 2009.
ACM is organized into over 170 local chapters and 35 Special Interest Groups (SIGs), through which it conducts most of its activities.
Many of the SIGs, like SIGGRAPH, SIGPLAN, SIGCSE and SIGCOMM, sponsor regular conferences which have become famous as the dominant venue for presenting new innovations in certain fields.
The groups also publish a large number of specialized journals, magazines, and newsletters.

Journal Credibility ? As you start to find out more about an area
you will start to see that there are certain journals that people researching in the area target
When you come across a journal for the first time, a way of measuring its ‘quality’ is the ranking it has journal citation reports

Finding Research online
Effective Searching Let us consider searching for information
relating to 'Project-Based Learning'
The Hyphen The first thing to note is the hyphen between
the words 'Project' and 'Based‘ Will every web-page relating to this subject have
the hyphen in it, or will some just leave it out? If you just leave it out the search engines will find
the phrase with or without the hyphen.
![Page 52: Literature Review](https://reader035.vdocument.in/reader035/viewer/2022062814/568167e2550346895ddd483d/html5/thumbnails/52.jpg)
Finding Research online
So the first search to try is "Project Based Learning"
if this returns 10,000 links then try "Project Based Learning" "PhD Thesis" "Project Based Learning" "Masters Thesis“ “Project Based Learning” “Masters Thesis”
Declaration this may return PhD or Masters thesis on
the subject you require information on.
![Page 53: Literature Review](https://reader035.vdocument.in/reader035/viewer/2022062814/568167e2550346895ddd483d/html5/thumbnails/53.jpg)
Finding Research online
To find other 'good' pages relating to your subject matter, try "Project Based Learning Link*"
for "PBL Links" or "PBL Link Page" "Project Based Learning Portal*"
for "PBL Portal" or "PBL Portal Page" "Project Based Learning Webring*"
for "PBL Webring" or "PBL Webrings" "Project Based Learning FAQ*"
for "PBL FAQ"or "PBL FAQs" or "PBL FAQL"or "PBL FAQLs"
![Page 54: Literature Review](https://reader035.vdocument.in/reader035/viewer/2022062814/568167e2550346895ddd483d/html5/thumbnails/54.jpg)
Finding Research online
If you are looking for papers relating to "Project Based Learning", try "Project Based Learning" Bibliography "Project Based Learning" Literature Review "Project Based Learning" Literature Survey "Project Based Learning" Overview "Project Based Learning" “A Roadmap”
Unlike the previous section where we were looking for 'good' pages and put the entire phrase in double quotes, in this section we are only putting the subject matter we are investigating in quotes and the rest of the terms are free text, in this way we can find pages which may not be titled, for example, "Project Based Learning Bibliography", but may be a bibliography which contain references to Project Based Learning.
![Page 55: Literature Review](https://reader035.vdocument.in/reader035/viewer/2022062814/568167e2550346895ddd483d/html5/thumbnails/55.jpg)
Finding Research online
If you are looking for a more specific topic, for example, "The Impact of the Web on Project Based Learning", try "Impact of the Web on Project Based Learning"
(unlikely) "Project Based Learning" overview web "Project Based Learning" survey web "Project Based Learning" review web "Project Based Learning" assessment web
![Page 56: Literature Review](https://reader035.vdocument.in/reader035/viewer/2022062814/568167e2550346895ddd483d/html5/thumbnails/56.jpg)
Finding Research online
Also consider web-sites which will be using the acronym for "Project Based Learning"
so try "PBL" "P.B.L." Consider the acronym for "Virtual Learning
Environments", it could be "VLE"or "VLEs"or "V.L.E."or "V.L.E.s"or "V.L.Es", so try
"VLE*" "V.L.E*"

Literature Survey
Here is a good tip:
![Page 58: Literature Review](https://reader035.vdocument.in/reader035/viewer/2022062814/568167e2550346895ddd483d/html5/thumbnails/58.jpg)
Literature Survey
Find an up-to-date thesis that is closely related to your research question (your supervisor should be able to help you with this, if not, search the web) and use this as a launch pad to your research
This is a very useful starting point since it will give you an immediate overview of your research field.
![Page 59: Literature Review](https://reader035.vdocument.in/reader035/viewer/2022062814/568167e2550346895ddd483d/html5/thumbnails/59.jpg)
Some Considerations When Using A Thesis As A Starting Point
Regional Variations : Different countries, different regions and even different universities have differing standards for their dissertations, so, whilst the dissertation is a useful starting point, it can only be considered as such, and is not a template for your own work.
Correspondence of Research : The dissertation that you are using should have a significant overlap with your own research, but there are bound to be differences, therefore, your own literature review will be very different to the one you have found, since yours is aimed at highlighting the ‘gap’ that you wish to address.
Quality of Research : The quality of the dissertation is something you will need to consider, how comprehensive is this person’s work ? Have they missed any important papers or major blocks of research ?
