I have written a number of posts related to thesis writing. Many of these posts are connected with the book, Helping doctoral students write: pedagogies for supervision (Kamler and Thomson, 2006, now being updated for 2013). Some of them are rehearsals of ideas for a new academic writing book written for doctoral researchers (to be published in 2014).
Here are some of the most popular posts:
