The ‘three papers’ Format of PhD thesis
This short guide introduces the idea of a PhD thesis consisting of ‘three papers’ as an alternative format for writing-up the results of three years’ PhD research. It compares and contrasts the conventional PhD thesis with the ‘three papers’ model, highlighting the main differences between them. It then suggests a rough timetable for producing a ‘three papers’ thesis in three years. Finally, it provides answers to some frequently asked questions.
2. The conventional PhD thesis
The conventional PhD thesis has (typically) the following elements:
For further information on the conventional thesis please consult the dedicated section (paragraphs 3.1 and 3.2)
3. The ‘three papers’ model
Under the ‘three papers’ model, a PhD thesis consists of three separate, publishable, papers. The papers should be of normal journal article length (say, between 5,000 and 10,000 words), depending on the editorial norms of the journal chosen jointly with the project leader (who is also the main supervisor). The three papers are each free standing (in the sense that each can be read and understood independently) but should be on related themes. The three papers are normally preceded in the thesis by a short introduction to the overall topic, which may contain essential background information. There may also be a general literature review.
Therefore, the ‘three papers’ PhD thesis looks like this:
The total number of chapters is thus usually five, and the total length approaches 150 pages of A4 (a maximum of about 35,000 words). As with the conventional PhD thesis, appendices of unlimited length may be added, but these appendices are commonly appendices to each paper, rather than appendices to the thesis as a whole.
Regardless on the format chosen - conventional or three-paper model - a short version of the thesis should be submitted by the same deadline indicated for the full thesis.
The short version of the thesis in Article Format is aimed at presenting the concise summary of the whole thesis and must be understandable without references to the extended version of the thesis (both conventional or three-paper model)
