On the morning of Tom Marshall's PhD defence, he put on the suit he had bought for the occasion and climbed onto the stage in front of a strong audience, including his parents and 6 examiners. He gave a minute-long presentation, then faced an hour of cross-examination about his past 5 years of neuroscience research at the Donders Institute for Brain, Cognition and Behaviour in Nijmegen, the Netherlands.
A lot was at stake: this oral examination would determine whether he passed or failed. I had enjoyed the whole experience far too much, and ended up talking for a few extra minutes. Marshall's elaborate, public PhD assessment is very different from that faced by Kelsie Long, an Earth-sciences PhD candidate at the Australian National University ANU in Canberra. Her PhD will be assessed solely on her written thesis, which will be mailed off to examiners and returned with comments.
She will do a public presentation of her work later this year, but it won't affect her final result. PhDs are assessed in very different ways around the world, purpose of phd thesis. Almost all involve a written thesis, but those come in many forms. In the United Kingdom, they are usually monographs, long explanations of a student's work; in Scandinavia, science students typically top-and-tail a series of their publications. The accompanying oral examination — also called a viva voce or defence — can be a public lecture, a private discussion or not happen at all.
There is wide variation across purpose of phd thesis and from one institution to the next. This isn't necessarily a problem in itself, but some researchers worry that the decades-old doctoral assessment system is showing strain.
Time-pressured examiners sometimes lack training and preparation for PhD assessments, which can lead to lack of rigour. Farrar, like other scientists, suspects that the PhD assessment is not keeping up with the times. Single-author tomes seem outdated when much of research has become a multidisciplinary, team endeavour.
Research is becoming more open, but Purpose of phd thesis assessments can lack transparency: vivas are sometimes held behind closed doors. Some PhD theses languish, little-used, on office shelves or in archives. What's more, little attention is given in the PhD assessment to soft skills such as management, entrepreneurship and teamwork, even though these are an essential part of life beyond the PhD, and students are increasingly leading that life outside academia.
The council organized a workshop in January this year called Future of the PhD Dissertation, purpose of phd thesis, and in March, the Australian Council of Learned Academies ACOLA in Melbourne examined changes to the thesis as part of a review on researcher training. Some scientists and education experts welcome the attention. Academics agree about one thing regarding the PhD assessment — its aim. The traditional goal is to demonstrate the candidate's ability to conduct independent research on a novel concept and to communicate the results in an accessible way, purpose of phd thesis.
Where the academics differ is on how best to achieve that goal. Shirley Tilghman, a molecular biologist and former president of Princeton University in New Jersey, sees merit in the monograph form of the thesis.
But should the thesis include academic publications, too? Purpose of phd thesis the norm at the Karolinska Institute in Stockholm, Sweden, where most purpose of phd thesis are a compilation of the student's purpose of phd thesis papers, along with a relatively short discussion, perhaps 50 pages long.
The rationale is that publishing should be part of training because it better equips students for academic life and securing jobs. Some students who complete a monograph end up wishing that they had spent more time on writing papers.
James Lewis successfully defended his physics PhD at Imperial College London in Octoberbut he thinks that his one published paper landed him his postdoc at NASA's Goddard Space Flight Center in Greenbelt, purpose of phd thesis, Maryland. But others argue that the pressure to publish could rob PhD students of valuable parts of their studies, such as the time to shape their research path and to think creatively and independently.
Long is working at ANU towards a thesis-by-publication: she's written and submitted one paper and has started on a second, purpose of phd thesis. But she's struggling, purpose of phd thesis.
What's more, her strategy depends on things at least partly outside her control — on her PhD generating enough complete studies for publication and on a reasonably timely peer-review process.
Completed PhD theses are typically stored in university libraries — but that doesn't mean that they are read or used. Scientists do tend to keep a copy of their theses in their office or lab for use by students and colleagues. Neil Curson, a physicist at the London Centre for Nanotechnology, says that his PhD, written more than 20 years ago, is still consulted by his students when they come into his lab.
Many theses, however, end up collecting dust. Whatever form the thesis takes, it has to be assessed — in most countries, by a panel of experts, and often involving an oral exam. In Israel, the viva is optional and very few students choose to have one; in the Netherlands, it is formal and ceremonial; in the United Kingdom, it's typically a private affair with two or three examiners; and in Australia, it's hardly performed at all.
That's largely because, historically, there weren't enough experts in the country to examine the work in person and it was costly to fly them in, she says. Holbrook and her research team published a study last year that compared the assessment methods used in Australia with those in New Zealand and the United Kingdom T. Lovat et al. Higher Ed. The review on Australian research training published in March didn't support adding a viva either, but it did recommend a move towards more continuous assessment of a student, rather than waiting until the end of the training.
Some researchers see problems with the viva. It's not uncommon for nerves to get the better of a student, and for them to freeze in front of their audience, purpose of phd thesis small it is. Examiners could worsen the situation by asking very difficult questions, says David Bogle, purpose of phd thesis, a chemical engineer at University College London.
This shouldn't be allowed. Most researchers don't support a global standard for the PhD assessment. A one-size-fits-all approach would be impossible to implement, they purpose of phd thesis, and the type of assessment — be it continuous appraisal, written thesis or oral exam — should depend on discipline, project, student, supervisor and institution.
But many feel that the system could be improved — by making the thesis shorter, for one. Data from ProQuest, which stores 4 million theses, show that purpose of phd thesis average length of biology, chemistry and purpose of phd thesis PhDs soared to nearly pages between and That could be because students are analysing more complex questions, performing longer literature reviews and using increasingly complicated methods that require lengthier explanations see 'The expanding thesis'.
Farrar says that a slimmed-down document would be more appropriate. That could follow the concise format of a research paper, and include a review of the field, then short chapters on methods, analysis and discussion. And the examiners will probably read it all.
That isn't necessarily the case now. Examiners have to find time to review theses in between research, teaching, grant-writing and many other demands. That means an examiner might skim through years of a PhD student's work in just a couple of hours. One way to better reflect the team-based nature of science would be to write a joint thesis, an approach that has been used in arts and humanities graduate education in the past.
However, this can make it difficult to assign credit. There is another matter to wrestle with — the fact that half of science PhD graduates in the United States are choosing careers outside of academiapurpose of phd thesis, according to the National Science Foundation's Survey of Earned Doctorates.
Increasingly, institutions offer courses to PhD students in skills such as teamwork, management and research ethics, but these skills aren't usually assessed formally. The viva would be one opportunity to do so, perhaps by seeing how students react to various scenarios. Alternatively, as the ACOLA review suggested, PhD candidates could accrue credits in transferable skills through professional-development activities that purpose of phd thesis recorded in a portfolio.
Farrar thinks that a change in emphasis could help. Rather than thinking of the thesis and viva as an exam, it should be viewed as the culmination of a long project. Mewburn stresses that whatever form the assessment takes, it should focus more on the individual than on their work. It's difficult to find figures on how many students fail their PhD if they get to the point of submitting a thesis but, anecdotally, scientists say that few flunk it outright.
More often, students are sent away with minor or major corrections that have to be completed before the PhD is awarded. There are theories that few students fail because universities want to keep their number of graduates high for the rankings.
But most researchers dispute this, and point to other reasons. One is that weak students are likely to have dropped out before they reach the final assessment. Furthermore, purpose of phd thesis, supervisors and the supporting institutions typically work hard — through regular reviews and assessments — to make sure that a candidate and project are of a sufficient standard before purpose of phd thesis thesis is submitted.
Nerad sees no need to reform the final PhD assessment. For her, the problem lies with the variability of graduate education as a whole. During her tenure as Princeton's president, Tilghman was often asked if there was a perfect way to assess a PhD course. Not many liked her answer — that she could purpose of phd thesis really evaluate a student at the year reunion. If they do, you've done a good job. If they haven't, you haven't, purpose of phd thesis. You can also search for this author in PubMed Google Scholar.
