Strategies for revision

Scientific writing can be thought of as a two-stage process in which we first write for ourselves to discover what we think, and then transform our writing through revision, so that it works for others, too. Below are some ideas and strategies for tackling the revision process with success.

Deducing readers’ needs

Are you a genomics researcher who’ll be submitting to a computational biology journal read by biologists and mathematicians alike? Or an environmental engineer hoping to publish in a restoration ecology journal? As science becomes increasingly interdisciplinary, we often find ourselves writing for audiences that have very different perspectives and goals from our own. So, if one goal of revision is to produce prose that serves these diverse readers, how do we decide what readers need?

  • Choose the journal you’ll submit to before you start writing. Then, read the guidelines for authors or analyze the writing of a few papers from the journal (preferably well written ones!) to get a feel for how authors frame their work, the background they include and the language they use.
  • As Paul Halmos says in How to Write Mathematics, ask yourself who you want to reach and then write to that person. That is, picture a smart, interested reader who has little background in your field and is skeptical of your approach. Then ask yourself: What extra information might s/he need to grasp the significance of my research problem? What hard questions might this person ask about my methods or results? Or, on a more basic level, what difficulties might this person have understanding my work, and how can I phrase things to avoid these difficulties?
  • Ask a general reader to review your writing before you revise. Your advisor and co-authors are excellent reviewers of the scientific content of your paper. But because they’re just as familiar with the research as you are, they may miss places where you aren’t being clear, are making leaps in logic, or using too much jargon. That’s where a general reader – your spouse, a graduate student friend in another field – can really help.

Think globally, then locally

It’s always preferable when revising to focus on “global” issues first – those concerned with the overall message, argument and organization of a piece – before addressing “local” problems, such as grammar, word choice, sentence structure and so on. Nevertheless, less experienced writers – and reviewers – often have a difficult time letting local issues go; their tendency instead is to polish, polish, polish as they write, or to correct these matters compulsively as they review someone else’s work.

What’s wrong with this? The main problem is that it can be very inefficient. Often we spend a lot of time refining a sentence, paragraph or section only to throw it out later because it doesn’t fit. What’s more, focusing on local issues too early can interrupt our train of thought, so that we end up forgetting where we’re going overall, or fail to capture key insights on paper.

Doing some polishing as we write is inevitable. But during the early stages of drafting and revising, try to stay focused on the big picture by asking yourself these kinds of questions:

  • What am I trying to say? Have I discovered my main point or “bottom line” yet?
  • How is my overall argument or message taking shape? Where am I including too much information – or not enough? Are there any leaps in my logic?
  • Is the content organized in support of my main point or message?
  • Am I serving the needs of the reader? (See the discussion above and the handout “Turning writer-based prose into reader-based prose.”)

I just can’t see what’s wrong…

Putting “fresh eyes” on a piece of our writing, so that we recognize where the problems lie and can fix them, is tough. If you count yourself among those who just can’t tell where and what to revise (and you’re not alone), here are a few strategies to help you:

  • Put your work aside for a time. At least a week is good, longer if you can spare the time. Try it, and you’ll likely find yourself saying, “I wrote that? It doesn’t make any sense!”
  • Ask a friend or colleague to read a passage from your work, and then explain out loud what s/he thinks you were trying to say. This should not only give you a sense of how clear your main points are, but it should also help keep the reviewer from picking on grammar, word choice and other “local” issues (see above).
  • Read your writing aloud to yourself. Nothing reveals convoluted, wordy and confusing prose faster than hearing it spoken aloud.
  • Get a good critique. Although we can all learn to better evaluate our own work, nobody in the end can do without a good editor or reviewer. Just make sure you pick yours carefully: Someone who’ll focus on larger issues rather than local ones; who’ll give specific feedback (Comments like, “I get lost in this section,” or “This great!” don’t cut it); someone, in short, who is exacting and honest but kind, whose feedback encourages rather than discourages you from revising. Note that you may need to explain to this person what you’re looking for in a critique.

Exploratory writing in scientific writing

From what I’ve seen as a writing instructor so far, graduate students in the sciences tend to view writing as an activity that merely bookends the real work of data collection and analysis; that is, writing is viewed as means to obtain money at the beginning of a project, as well as something to be gotten through as quickly as possible once a project is finished and ready to be published.

But “exploratory” writing — informal writing outside the structured realm of grants and journal articles — also has a place in science, I think, particularly because of its role in helping us to discover, develop and refine our own ideas. You don’t have to take my word for it, however. Below I’ve posted quotes from a mathematician and a scientist on the value of free-form, exploratory writing.

“We all know that one way to work out our thoughts is to engage in an animated discussion with someone whom we respect. But you can instead, à la Descartes, have that discussion with yourself. And a useful way to do so is by writing. When I want to work out my thoughts on some topic – teaching reform, or the funding of mathematics, or the directions that future research…ought to take – I often find it useful to write a little essay on the subject. For writing forces me to express my ideas clearly and in the proper order, to fill in logical gaps, to sort out hypotheses from blind assumptions from conclusions, and to make my point forcefully and clearly.” –Steven G. Krantz, A Primer of Mathematical Writing

Examples of exploratory writing include journals, notebooks, marginal notes in books, nonstop freewrites, reading logs, diaries, daybooks, letters to colleagues, notes dashed off on napkins, early drafts of essays, and what physicist James Van Allen, author of more than 270 scientific papers, calls “memoranda to myself”: “The mere process of writing,” explains Van Allen, “is one of the most powerful tools we have for clarifying our own thinking. I seldom get to the level of a publishable manuscript without a great deal of self-torture and at least three drafts. My desk is littered with rejected attempts as I proceed. But there is a reward. I am never so clear about a matter as when I have just finished writing about it. The writing process itself produces that clarity. Indeed, I often write memoranda to myself solely for the purpose of clearing up my own thinking.” –Engaging Ideas: A Professor’s Guide to Integrating Writing, Critical Thinking and Active Learning in the Classroom, John C. Bean (2001) John Wiley & Sons, pp. 97-98.

Writing the discussion section

The purpose of the discussion section is straightforward enough — to describe the significance of your results and what they mean to your field of study. However, organizing this section can be a challenge because the structure is much more loose than in the methods, results or even the introduction.

Structuring the discussion

A good place to start is with a one-paragraph review of your major findings that ends with a one- or two-sentence statement about their overall importance. You can then expand from there by answering the following questions:

  • How do your results fit into the larger context of what is already known about your subject? Do your findings agree or contrast with the findings of others?
  • What are the theoretical and/or practical implications of your study? How are your findings an advance over what others have shown?
  • What are the limitations of your study? Could these limitations have biased your results in any way?
  • What future directions does the research suggest?

Note: Keep in mind the inverted pyramid style. That is, it’s generally a good idea to lead with the most important points you want to make and follow with points of lesser and lesser importance.

Common pitfalls to avoid

Overstating the significance of the work. Many articles on scientific writing will caution you against this, and with good reason. However, an even bigger pitfall may be the one directly below.

Understating the significance of the work. While it’s true you should take care not to oversell things, it’s also true that young scientists tend to downplay the importance of their research. So, do think about the larger meaning of what you’ve done and then don’t be afraid to say it. As William Wells (2004) writes, there probably was a bigger idea behind your work than the possibility of protein X and Y binding to one other, so “make sure you convey that reason and that excitement.” In other words, readers should not come away from your paper thinking, “so what?”

Being vague. Related to the point above, if you make general statements such as, “We believe our model can help experimental biologists understand their own systems better,” or “Our findings are valuable for the future design of bacteria that can do X and Y” be sure to explain what you mean. What specific insights will your model offer biologists? What exactly will your models contribute to the future design of microorganisms? If you’re hazy about this, reviewers are likely to ask you to provide some explanation and evidence.

Failing to address the question or problem posed in the introduction. “The Introduction and Discussion should function as a pair,” say Day and Gastel (2006). “Be sure the Discussion answers what the Introduction asked.”
