Stay on Topic

One major malfunction in thesis construction is to write about what you want to discuss rather than what you need to discuss. Naturally, we are inclined to spend time on the things that interest us and avoid the topics that send us progressively further into comas as we type each word.

At the point of starting, many people think their thesis will be perfect, or at least the best thing they’ve ever written. The result is that they start by reading fifty papers for the first sub heading and writing almost as many pages. This is not a good strategy. Even if this first subheading is not far too detailed, continuing at the same level will be exhausting and you run the risk of burning out.

This is not say your thesis shouldn’t involve a lot of effort, but try and keep your expectations realistic.

  1. It is a good idea to rate the importance of each section so that you know roughly how much time you need to spend on it.
  2. No one will congratulate you on the size of your thesis. Your examiners are busy people and the more you write the more they have to read. Cut bits if they aren’t relevant. It may hurt, but it needs doing.
  3. If you are struggling to write a section, make bullet points of all the important bits you have covered thus far and the ones you still need to do. Come back to it later with fresh eyes.
  4. When writing the sections you find most interesting, repeatedly refer back to your story and ask yourself if what you are writing is relevant.
  5. Don’t ignore the bits you find boring. If your examiners see noticeable gaps in certain areas, then they will spend more time on these in the viva and you may have to add them in your corrections.

When I started writing my thesis, I was going to read every paper ever written that was remotely related to my project. It was going to be perfect.

This is impossible.

After a few very thoroughly researched sections, I semi-quickly realised that the workload was unsustainable. Unfortunately, I’d started on the more general topics which were not so relevant to my project. It made for a good opening to my thesis, but that work would have been better placed in later sections where more detail was expected.

Don’t Only Read a Single Review

Reviews are generally not co-written by people of opposing opinions. They are views of one individual or lab and can be heavily biased towards one point of view. Most likely, they will also give disproportionate weight to their own research.

Read multiple reviews from different labs, and, whenever you can, read the primary research.

Get Practical Tips
 

  1. Whenever a review on a subject says something is incorrect or debatable, look up the paper they are talking about and see if that author wrote a review on the subject. This is likely to be a good source of the opposite opinion.
  2. For the important points within a review, make sure you look at the primary data. It is not so rare that people misinterpret other people’s work according to their own biases.
  3. Don’t reference reviews in your thesis. If you can’t find the primary research that shows something, then you don’t know it’s true. There are plenty of myths out there.
  4. The exception to the above tip is direct quotes of someone’s opinion – which can come from reviews.
  5. Don’t judge the strength of conclusions based on the opinions of reviewers. Sometimes, the reasons people write “showed” instead of “indicated,” can be arbitrary. Read the primary data and come to your own conclusion on the strength of the data.
  6. If the reviews you read are older, then it is important to check more recent discussions of the subject. Perhaps bits have been disproved or expanded on. Your examiners will want to know your knowledge is current.
 
Read Personal Perspective
 
I’ve read multiple reviews where the author has ignored or downplayed evidence that runs contradictory to their argument. Simply basing your discussion on one person’s opinion can make your thesis look biased or sometimes even wrong. If the review is older it can even be talking about information that has since been disproved as if it is still current.

Don’t Include Bad Data

Critically assess the strength of your data before you add it to your thesis. When you have spent ages doing a bit of research, it is tempting to add it to your thesis simply because otherwise it feels like you wasted the time. However, if it does not have the relevant controls or is in some other way inaccurate or irrelevant, then you will only waste more of your time by including it.

Your thesis is not the place to show how much work you’ve done. It is the place where you show off your best work.

Get Practical Tips
 

  1. No one will congratulate you for the length of your thesis. If the work is poor or irrelevant your examiners will want to know why you included it. They may also insist work is redone or completed when its absence would not have been questioned.
  2. Only include work that is both relevant to your story and of high quality. Adding unnecessary data only increases the chances your examiners will find problems.
  3. Check the conclusions of your data. Always ask yourself if there is another interpretation.

I was overly enthusiastic about research and was always doing my own experiments, most of which never went anywhere. However, there were a few that I spent so long on that it was impossible to leave them out of my thesis.

As it turned out, this was a disaster. My examiners were not impressed as the data was not related to the rest of my work, did not contain all the necessary controls, and the error bars were large. They said my conclusions were unfounded and nearly made me do the experiments again, but decided that I should simply cut them from my thesis.

My advice is to remember that sometimes you waste time. Regard your bad analyses as a learning experience and don’t include them in your thesis – this will only waste more of your time.

Don’t Do Something Stupid

No set of guidelines is complete without saying not to cheat. It is obvious to most people, but there are still a few slow swimmers who haven’t learnt this lesson yet. They have got away with it thus far so they think they can continue to do so.

Well perhaps you can, but if you’re caught it will destroy any hope of graduating or getting a reference from your supervisor. The risk is completely and totally not worth the reward.

Plagiarising and altering data are the fastest and easiest ways to fail your degree. If you are stressed because you have no data, there are always paths to achieve this honestly. Computers have long memories and spot data manipulation and plagiarism easily.

In the end it comes down to this:

  • People who comprehensively and logically explain why their research failed still pass their degrees.
  • People who cheat fail their degrees.

There was a boy in my undergraduate degree who pasted a single paragraph from a review into his dissertation. Why he felt the need to do this – when he’d written the rest of the lengthy project – is probably not even known to him, but the consequence was that he got zero for the piece. The university considered this lenient as they often expelled people, but his degree still dropped a grade and he no longer fit the criteria for the job he had lined up.

You May Procrastinate

Whilst writing your thesis, you will find things interesting that you never thought possible. Suddenly, cleaning the house will seem meaningful and fulfilling, playing those fruit matching games will no longer be void of all purpose, and calling your parents will become exciting. This is all normal.

There will also be points when looking at your thesis makes you feel a bit sick. Under these circumstances it is ok to take a break. If you fancy cleaning that bit of mould behind the sink, then do that.

Sometimes you need to push through the boredom and actually write something, but when you need a break take it, and don’t feel guilty. Your thesis will still be there when you get back, and likely you will work a lot faster and better after a break.

Get Practical Tips
 

  1. Schedule how much you need to write at the start of each day. Meeting smaller targets is easier.
  2. Reward yourself for good work with breaks.
  3. Don’t stress yourself if you have procrastinated for too long. Everybody does it. Just start work again in the knowledge that you are now fresher than everybody else.

  • After a particularly gruelling section of my thesis, I once stopped for a five minute break to play some Plants vs. Zombies. I told myself five more minutes so many times that by the time I finally finished, the sun was rising again and the idea of returning to my thesis had only become more repellent.
  • I once returned home to find that my flatmate had completely run out of ways to procrastinate. He’d cleaned the entire house, including the rooms no one ever went in so that the entire place smelt like perfume. I lived with him for a year before that and he’d never so much as changed his bedsheets, but clearly anything was better than thesis writing.

Check Your Thesis Thoroughly

Once you have finished your thesis, the temptation will be to put it down and never look at it again. This is a bad idea. Take a break: a weekend, a week, whatever you have time for, then read it through.

Don’t send your supervisor a first draft to read. It’s a waste. Most likely they will make changes to rubbish that you would have changed regardless. You want to send your supervisor something that you would be happy to submit. It may still come back with a fair quantity of red pen, but your finished product will benefit.

The main difference between good and bad pieces of work is the amount of times the author has checked it through.

If you need more evidence of this, here is a quote from a world renowned writer.

“The first draft of anything is sh*t.” – Ernest Hemingway

Get Practical Tips
 

  1. Don’t wait until you have written every section to start checking it through. This will be a huge barrier. Check through one section while you write the next one. Break your thesis up as much as you can.
  2. Giving your first draft to your supervisor will impress no one, and if they don’t just hand it back they’ll end up changing things you could have done yourself and miss more important things.
  3. After you have made all your supervisor’s corrections, check it through once, leave it for a while, and then check it again with fresher eyes.
  4. Likely by the time you have a polished product you know it so well that it is impossible for you to notice mistakes. If you can, give it to someone else to read. They don’t even have to understand it as long as they know what words and sentences should look like. Silly mistakes make your work look more rushed than you might like to believe.

During my undergraduate degree it took me forever to realise why my essays were not coming back with the marks I thought they deserved. Finally, I was so annoyed that I sat down to re-read one of them. I could hardly believe it was the same essay. Why? Because I hadn’t checked it through. The moment I started doing this – even if I put less effort into actually writing it – my marks rocketed.

Revising for Your Exam: Assess Your Weakest Section

After you have finished and handed in your thesis, you may have to do an oral exam on your work.

It is a good idea to assess the weaknesses of your thesis before you hand in, but make sure you do it afterward.

Unfortunately, examiners are all different, and the bits of your project they choose to focus on will depend partly on their own interests, but also on your weaknesses. Thus, it’s a good idea to analyse which sections are your weakest and pay special attention to those.

Get Practical Tips
 

  1. Re-read the more important papers you referenced. By the time of your examination it may have been a while since you last looked at them.
  2. Check to see if you have all the relevant controls that give your results meaning. If you don’t have them, start thinking up excuses.
  3. If there was a section you were not particularly keen on writing then that is a good candidate for a weaker section.
  4. Any bits where you weren’t 100% clear what someone was talking about, but you still wrote about it should receive specific attention.
  5. Bits where the literature is not clear and you could be asked to give your opinion are also good candidates for revision.
  6. Make sure you read up on what your examiners focus on for their own research. Start thinking about the parts that link their research to your own. You may receive heavy questioning on these areas.
  7. Write down some questions they could ask you and practice answering them.

After my friend told me he got loads of questions on his materials and methods, I spent ages revising this for my viva, but my examiners skipped the section entirely. On the other hand, the work I did re-reading my references came in very handy. Not everything you do will come up, but make sure you have a good all round understanding for the bits that do.

The First Attempt is a Trial

The first time you do something should not be an attempt to collect as much data as possible. Quite the opposite, you should cut the procedure down to its bare bones doing only the minimum to find out if it works. Then you can correct any mistakes before you do the bulk of your work.

Complicating the procedure unnecessarily by collecting extra data will only increase the risk of making a mistake. Always learn the protocol by attempting the procedure before you attempt to maximise the data output. Otherwise, the most likely outcome is stress and failure.

Get Practical Tips

 

  1. Slowly increase the number of samples/patients/volunteers used in each research project. The first few times you will still be learning, and taking things in steps will reduce the chance of introducing error.
  2. If you need something to work first time, then you can try doing a dry run.

This advice is especially important if the protocol involves specific incubation times. The more samples you use, the harder it is to keep to those times.

It took me longer to cotton on to this than it should have. In every experiment I did in the early years, my goal was always to obtain the maximum data from it possible.

I watched my supervisor run 50 samples perfectly spaced at the correct intervals, and logic followed that I could do it as well.

WRONG.

After a lot of dead cells, stress and time spent staring at a machine that looked like a 70s black and white TV, I realised I’d forgotten something that made the whole thing pointless.

Instead of wasting one or two samples, I’d depleted my cells to run the maximum amount, and had to wait for them to grow back before I could try again. But even if I had remembered everything, the experiment would still have been a waste because I was so inefficient at the steps that the first samples treated were sitting in the fluorescent dye for much longer than the last ones. Each sample had received significantly different treatment by the time they were ready to analyse.

I wasn’t ready to work with those numbers.

Change One Thing at a Time

If you are doing a research project that isn’t working, then change one thing at a time.

When you see the complete absence of usable data, it will be very tempting not to follow this advice because the assumption is that something has gone drastically wrong. However, this is not necessarily the case. Very often a single problem is sufficient to throw a procedure way off track. Thus, if you change more than one thing, you may well be correcting the error, but introducing another one.

Get Practical Tips

 

  1. Once you have got the procedure working, repeat it several times on different days before you move on. Then, if you ever have to come back to it, you will remember how to do it well.
  2. If the data are acceptable but not great, then don’t accept mediocrity. Think about how you could make the procedure better.
  3. Sometimes it will become clear a procedure has failed before completion. In some cases, where the workload and cost of completing it are not high, it can be worth finishing and analysing it. You can learn a lot from the outcome of failed work, and it may help you to identify future mistakes.
  4. Don’t compensate for not understanding the procedure by doing it more times. If you don’t know why it isn’t working, find out by researching the procedure. Otherwise you will just have lots of failures.

  1. The fastest way to correct error is to change one parameter to several different values at once. Then if none of the values for that parameter yield good results, it is likely (assuming you picked a good range of values) that the test parameter was not the problem.
  2. Check to see that none of your reagents have expired. This accounts for many failed experiments. If reagents are cheap make up a new batch before repeating failed experiments.

 

Read Personal Perpective

 

Whenever one of my experiments failed, and admittedly this was not an infrequent occurrence, I always felt rushed to do it again and present something useful to my supervisor as quickly as possible.

This was a huge mistake. It wasn’t until I was doing my first year report that I properly researched the problems with the experiment. After this, things went a lot more smoothly, but if I’d just done the research after the first experiment, I could have saved myself a lot of time.

The problem is not always immediately obvious, requiring more than a token alteration. Although it might feel like you’re wasting time, the opposite is true.
