Transcripts
a literature review is a summary of the
existing research on a particular topic
it's typically done at the beginning of
a research project and I did one for my
undergraduate thesis for my Master's
thesis and for my PhD thesis and in this
video I'm going to answer all of your
literature review related questions the
first thing is how do you start a
literature review well to start a
literature review surprisingly or not
surprisingly you need literature where
do you find that literature well there's
a ton of places the first place I would
go to is ilicit
docomo which allows you to ask a
research question and get all of the
papers related to that question for
example here I can say how effective are
conditional cash transfer programs it
will go away and search more than 125
million academic papers and here are the
first four abstracts here and here are
all of the different researched
peer-reviewed papers and that means that
experts in the field have looked at
these papers and said yes they are true
they are something that is a valuable
contribution to the research field so
that's why you should be reading them
and we can go through and see that we've
got a little summary and we just click
through all of these and we can go and
read them individually that's one way
semantic searching the next thing you
can do is use lit Maps LP Maps creates a
map of literature for you to search so
we can go in and create a map here I've
created a map from one of my
peer-reviewed P papers that I wrote
during my PhD and you can see I get a
nice map of all of the other stuff that
I need to read you can do this with a
Single Seed paper or you can put in a
load of different papers in this tab in
discover to find out a load of different
papers that you need to read about then
you can also use something like Google
Scholar this is old school this is like
OG uh science and research you go in you
just type keywords for example charge
transport in opv so so I'll click here
and then here are all of the different
papers that I should consider reading
clearly you don't need to read all of
them but we'll get into that in a minute
but this is where you start you start by
searching the literature you can have a
look since 2024 since
20123 and uh this is the foundational
activity for any literature review get
comfortable searching the literature and
you'll become a power user of all of the
literature that you're about to write
before you start reading any literature
you need to have a literature review
outline to work with so this is the
general structure of nearly every
literature review for any field it goes
like this first of all we start with an
introduction at the top this
introduction gives background
information about the research field
that you are investigating it's in a
reverse pyramid shape because this is
the very very broad step this is where
we're just sort of like looking at the
over aring umbrella of our research
field then optionally we can talk about
background and methods that are used to
um look for the research that we're um
going to talk about in the literature
review for example you may want to say
we looked at these databases we looked
at these sort of questions um and
background is the background of the
field that you're specifically
interested in so we're going a little
bit deeper which is why it's the next
step down on the inverse pyramid then we
need all of the main text and this is
all of the literature that you found
searched by either theme so you sort of
group it together is like this is a
group of research that I can talk about
because it's under one theme here's
another theme or here's another theme
and you put research under that so in
here you may have one 2 three plus
themes under which you will talk about
literature or which is very uncommon I
think these days but you may be lucky
that you may be able to sort this based
on time which means initially these
people did this and then they did this
and then they did this and that's how
you structure your literature review so
you say they did this first here's all
the literature in the initial stages of
that research then they did this here's
the next stage of research that the the
evolution of that research field here's
the next stage so it may be theme or
time it's completely up to you which one
you use but most people use theme once
you've outlined all of the main themes
and you've talked about the literature
under that theme then you need to have a
discussion to bring it all together this
is where you're looking at all of the
research themes and you're talking about
your specific research question why are
you doing this research uh into this
literature and how does it help you sort
of like answer the research question or
the um interest you have in a particular
research field and why you're looking at
the literature in the first place and
and then you're looking at conclusions
based on all of the stuff that you've
read all of the individual themes all of
the chronological studies all of the
papers you've included in this
literature review what conclusions can
you make specifically about the current
state of the field and that is the
general structure of nearly every
literature review ever produced now
there's an easier way to do it obviously
what I like to do is cod to chat GPT and
I just say create a literature review
outline for a study about and then
whatever I'm interested in here I've got
an example where it says the effect of
climate change on plants and as you can
see it says introduction background and
here it says I want basic concepts of
climate change then it says general
impact of climate change then we want
Direct effects of climate change on
plants you can see we've started Broad
and we're getting narrower and narrower
as the literature review goes on and
then we've got different themes so we've
got indirect effect of climate change on
Plants so altered Pest and disease
Dynamics that's a theme theme changes in
land use and habitat that's a theme and
then we've got other themes underneath
so this is how you can easily structure
and get a first kind of draft of the
structure of any um literature review
that you're writing for nearly any
subject it's just amazing and as you can
see down here the last one is conclusion
um summary of key findings and then
final thoughts on the importance of
further research so this is how we can
use chat GPT to structure our literature
review outline nice stuff once once
you've got all of the literature you
need to read and you've got a structure
under which to put that literature then
you need to just write you type out all
of the stuff in your literature review
before you do that you may want to have
a look at something like explain
paper.com that allows you to quickly
understand peer-reviewed papers
peer-reviewed papers are notoriously
hard to read They're dense they're thick
in academic language and here it's a
really nice way to sort of like just uh
get the simple summary and I think uh
this is one of the most uh powerful ones
explain paper.com all you need to do is
highlight a certain area and over here
it will say okay explain your
explanation as a middle schooler we can
move this up and down and then we just
click explain and underneath it will
tell you the undergrad explanation of
what you've just highlighted a really
great way particularly if you're early
on in your academic career if you're
undergraduate if you're in high school
this is a great way to unlock all of the
Power that's behind the horrible
language found in peer-reviewed academic
papers once you understand what's
actually in all of this you've collected
them into themes you need to write it
there are a few tools that you can use
so you can use jenny. a that's an auto
writer for research papers and
literature reviews you can use yu. a and
that is another sort of like Auto writer
for peer reviewed and papers but to be
honest with you the best thing you can
do is sit there with a Word document
with a Google Document Google um what do
you even call that Google Docs Google
word I completely forgot anyway you know
what I mean you sit there with a word
processor and you start typing you put
in your structured headlines and then
you say under each one what literature
you're going to mention and you start
fleshing it out it takes ages and ages
and many many revisions make sure that
you get someone you trust or your
supervisor to look over it as you're
writing it maybe each chapter or each
theme that you write you get someone to
look over it and then at the end they
look over everything all together it's a
really really long process it takes such
a long time for
my thesis it probably took a good few
weeks to get all of the information into
a sensible structure and literature
review so here we are here's one of the
themes overview of photocurrent
generation in organic photovoltaic
devices so that's just one of many many
themes in this uh thesis and depending
on what stage of study you're at it
could be long it could be short but
let's talk about that next okay how long
should a literature review be well there
are no hard and fast rules but I like to
think about it like this is there enough
in your literature review to provide
enough context to what you're doing and
what you're researching is there enough
context
for you to understand the problem that
your literature review is looking at and
addressing and also is there enough data
in there to talk about the upto-date
research and where the current state of
the field is that's really what we're
looking at but here's some rules of
thumb so if you're doing it for an
assignment one thing I recommend that
you look at is about 3,000 to 10,000
words that's normally good enough to get
an overview for example in my
undergraduate thesis it's only about
seven pages there's not much in there
there's some fancy diagrams there's lots
of references but ultimately um it's
about seven pages so it's not much so
3,000 to 10,000 words is all you need
for a small assignment or an
undergraduate thesis whereas for
Master's and uh Master's thesis and PhD
dissertations one thing I recommend is
you look at what's normal for your field
in some Fields it's like 10 pages in
other fields it can be up to 40 pages
but ultimately as long as you have
enough information and literature to be
able to provide context to your problem
and you provide an upto-date uh
representation of that research field
then you've got enough in there um like
I said I like to use just the guide of
what is normal for my research field
before I start writing my thesis so I
can say Okay normally it's about 20
pages and therefore I need to fill 20
Pages worth of stuff um and that is a
good starting point for almost any
literature review so there we have it
that's the introduction to literature
reviews I'd love to know what you think
and also I have got so many videos on
this very Channel about literature
reviews with AI how to find literature
using AI tools how to write it in
seconds using tools that are available
online I'll put all of the links Below
in the description so you can sort of
build on the knowledge that we've uh
gained in this video but if you really
want to go look at a powerful video go
check out this one where I talk about
how to write an exceptional literature
review using AI you won't be
disappointed go check it
