8 Editing

Read time: 9 minutes

 

Overview

Once you have the first draft, it’s time to edit! Most people enjoy editing much more than writing. Interpret the word revision as re-VISION: “See” your paper again; look at it objectively, sceptically, as if it is not your own work.

Here, we will use the Point-First approach developed by Ellen B. Zweibel and Virginia McRae to edit our writing in 5 layers, which is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License

Editing in layers

Editing your work especially, a thesis, can be a daunting task. There may be issues with the overall structure and story, problems with clarity, as well as spelling and grammar mistakes.

The Point-First approach involves separating these tasks and editing in five layers:

  1. The Big Picture
  2. Structure
  3. Continuity
  4. Clarity
  5. Final Proof

You can follow through the Editing in Layers guide online as you edit your work, and use this PDF checklist to keep track of your progress.

Watch the Point-First video below (transcript), to understand why it is important to edit your work in layers rather than trying to edit everything at once.

The Big Picture

The first step to editing your work is to consider context, audience, and purpose. Ask yourself: Who are you writing for, and why? Where will this writing be published? What is the expertise of your audience?

SCIENCE WRITING CONTEXTS

INNER CIRCLE LOCAL OR CHEMISTRY-SPECIFIC
  • progress reports
  • internal documents
  • emails to colleagues and supervisors
  • research updates
  • lab notebook
  • annual research updates
  • department-wide
  • specialized journals (e.g., Organic Letters)
  • conference proceedings
  • lab reports
BROAD SCIENCE GENERAL PUBLIC
  • science news sites (e.g., CIC News)
  • broad-readership journals (e.g., Science)
  • grant and scholarship applications
  • thesis
  • popular science magazines (e.g., Wired)
  • social media
  • essays (e.g., The Conversation)
  • news releases

Exercise: The Big Picture Read

Find a sample of your writing, either your first draft or something you already finished. Follow the Point First Checklist items and tasks under #2 “The Big Picture Read” to see how well your writing suits your the context, audience, and purpose.

  • What is the context? – a report, journal article, proposal in an application?
  • Who are the readers? – present and future readers, their characteristics and needs?
  • What is the purpose? – inform, recommend, update, warn, advise or persuade?
  • Write a note beside each paragraph on what the paragraph is about. Then use the notes to check that it meets the context, audience, and purpose.

Structure

The structure of your writing can refer to your overall structure, headings, paragraph, or sentence structure. Review the chapters on Sentences and Paragraphs to learn how to write with clarity and structure.

Exercise: Shaping Paragraphs

Find a sample of your writing, or use the paragraph below. Highlight all the important information, then restructure your paragraph so that those sentences are at the beginning or end of the paragraph. Watch the Point First video below to guide you (transcript).

Writing Sample from Rice University “Chemistry” (CC-BY): In ionic compounds, electrons are transferred between atoms of different elements to form ions. But this is not the only way that compounds can be formed. Atoms can also make chemical bonds by sharing electrons equally between each other. Such bonds are called covalent bonds. Covalent bonds are formed between two atoms when both have similar tendencies to attract electrons to themselves (i.e., when both atoms have identical or fairly similar ionization energies and electron affinities). For example, two hydrogen atoms bond covalently to form an H2 molecule; each hydrogen atom in the H2 molecule has two electrons stabilizing it, giving each atom the same number of valence electrons as the noble gas He.

Key Takeaways

Find a sample of your writing, either your first draft or something you already finished. Follow the Point First Step-by-Step Approach to editing your structure (halfway down the page), the steps are summarized below:

  1. Test your point-first openings: Check the first sentence of each paragraph
  2. Cut and paste your headings into a new document: Check the order
  3. Audit and revise your headings: Make them descriptive
  4. Main idea: Write 1-2 words describing the single point of each paragraph
  5. Cut topic sentences and last sentences and paste under headings

Continuity

In this next layer of editing, you can check the flow of your writing at the paragraph level. Each paragraph in your writing should have a single topic, but your writing will seem choppy if you don’t build connections from one paragraph to the next. Use clear transition words to connect your paragraphs. Beyond the words, consider how your sentences link paragraphs together and move your ideas along.

Exercise: Check your transitions

Find a sample of your writing or use the sample below. Use the following strategies to check your transitions.

  • Highlight all the transition words and phrases. Check for wordiness and repetitiveness, and remove any unnecessary words. [Video explanation]
  • Rewrite the second paragraph topic (first) sentence to create a better link to the ending of the first paragraph.

By and large, organometallic compounds find wide use in commercial reactions, both as homogeneous catalysis and as stoichiometric reagents. For instance, organolithium, organomagnesium, and organoaluminium compounds, examples of which are highly basic and highly reducing, are useful stoichiometrically. These compounds, however,  also catalyze many polymerization reactions.

Consequently, almost all industrial processes involving alkene-derived polymers rely on organometallic catalysts. The world’s polyethylene and polypropylene are produced, for the most part, via both heterogeneously via Ziegler–Natta catalysis and homogeneously, e.g., via constrained geometry catalysts.”

Avoid using ambiguous pronouns that refer to something from far back in the text. A common mistake here is to start a new paragraph by ambiguously referring to something from the previous paragraph. If your reader needs to stop and look back to know what you are talking about, this makes your writing difficult to understand.

Examples of Ambiguous pronouns.

Example 1 (modified from a Wikipedia entry)

Metals are shiny and lustrous, at least when freshly prepared, polished, or fractured. Sheets of metal thicker than a few micrometres appear opaque, but gold leaf transmits green light.

The solid or liquid state of them largely originates in the capacity of the metal atoms involved to readily lose their outer shell electrons.

“Them” is in a new paragraph, and the reader may not know what is being referred to, metals or sheets of metals, or gold leaf?

Example 2

The alcohol, a derivative of the aldehyde, it has a boiling point of 50 °C.

Which has a boiling point of 50 °C, the alcohol or the aldehyde?  You might know, but the reader will be confused.

Another trap that can break the flow of your writing is Using Too Many Acronyms (UTMA). In your research group or department, there may be a common understanding of some acronyms, and it can be easy to forget that they are not universal! Unfortunately, using unnecessary acronyms like UTMA in your writing slows down the reader because they have to look back in the text. Avoid UTMA!

Use this Point First Transitions Traps checklist to edit your writing transitions thoroughly, including checking the consistency of terms.

Clarity

Now that you’ve tackled the big picture, structure, and continuity, you can start to look at your words and sentences. In an earlier chapter, we already discussed ways to write with more clarity by controlling sentence structure, using active voice, and ambiguity. Point First has many incredible tools to help you improve clarity in your writing with a focus on these three topics. Clarity can also be an issue on the larger scale if what you wrote is too long. Follow this link to learn how to ruthlessly cut out 10% in 10 minutes!

Subject-Verb-Object Editing

Even if you tried to get this right in your draft, you probably still have some confusing sentences. Find a sample of your writing or use the sample below.

  • Highlight the subject, verb, and object in each sentence.
  • Are the sentences in the order Subject-Verb-Object?
  • If the Subject too far from the Verb?
  • Rewrite sentences to improve clarity.

This morning you, after checking the solvent containers, need to set up the HPLC for analysis. You can refill the solvent if it is less than half full. After I turn on the instrument, you need to record the pressure of the column. If you have a good reason to skip this step, but this goes against our best practices, then you will be responsible if the column fails.

In the example above, the first sentence is hard to follow because the subject is far from the verb and object. The last sentence has the same problem.

Wordiness and Passive Voice

Get rid of the clutter! Cut out or move any content that is irrelevant to the main message of the paragraph. See the example below, which is a modified text from the Wikipedia entry on Marie Curie (word count = 44).

Due to the fact that international recognition for her work had been growing to new heights, the Royal Swedish Academy of Sciences, overcoming opposition prompted by the Langevin scandal, honoured her a second time, with the Nobel Prize in Chemistry in the year 1911.

Suggested rewrite for clarity (word count = 18):

In 1911, The Royal Swedish Academy of Sciences honoured Marie Curie with her second Nobel Prize in Chemistry.

Who did what, and when?

Make sure you don’t have any misplaced modifiers! Modifiers are words that modify the meaning of a noun (e.g.,  “veggie burger”). From the sentence below, it’s hard to tell exactly what Alice did this morning, the reaction or the purification.

Alice purified the mixture obtained from a reaction she ran in the glovebox this morning.

For clarity, move the modifier closer to the noun it is modifying.

This morning, Alice purified the mixture obtained from a reaction she ran in the glovebox.

It is very common in science for verbs (e.g., conclude) to be turned into nouns (e.g., conclusion). This might not seem like an issue, but when overused this ‘nominalization’ can make for boring and passive writing.

Check your own work for the following common nominalizations used in science writing, and search the underlined endings to find them in your own text. Notice how it comes hand in hand with passive voice:

  • “calculations were performed…” [verb = calculate]
  • “the dependence of…” [verb = depend]
  • “the stability of…” [verb = stable]
  • “in agreement with…” [verb = agree]

Nominalizations

Rewrite the following sentences to fix unnecessary nominalizations. Then check your own writing! Removing nominalizations has the bonus effect of fixing passive voice and helping with wordiness.

  1. The calculations were performed on the cluster using density functional theory (DFT) and are in agreement with prior work.
  2. The intention of this approach is to create new materials with high stability.
  3. This result showed the dependence of our process on temperature and supported our implementation of the infrared control system.

The Final Proof

Only once you are done editing can you move on to proofreading. Proofreading is a final check for spelling, grammar, and consistency. If you start proofreading too early, you will waste time on words and paragraphs that still need work, or once that may not even make it to your final draft. The next chapter will provide an overview and tips for proofreading, and you can also check the Point First checklist and resources.
