1) Have a compelling and descriptive topic sentence. You saw this one coming, didn’t you? Most of teaching can be summed up in one directive: tell’em what you’re going to say, say it, and then tell’em what you said. The topic sentence is the guidepost that tells the reader what to expect. It sets up the coming argument. The topic sentence needn’t necessarily be the first sentence, but it should obviously come early. Here’s two ways of recognizing a good topic sentence:
1) Is the rest of the paragraph about the topic sentence?
2) If you go through your manuscript, highlighting just the topic sentences, is the manuscript still coherent?
2) A paragraph has an inevitable logic. The topic sentence raises expectations. Now you follow through with the meat of your argument: a set of logically connected sentences that clearly and concisely builds your case. If you’ve slaved over a paragraph and are still not getting the response you want from your readers, it’s often the case that your logic is flawed. Put another way, writing is one of the best ways of discovering what you do not understand about your topic. But a logically well-constructed paragraph is worth slaving over. Nothing else makes you feel so much like, well, an academic.
3) The juicy example. Remember, you are teaching your reader about something. The logic may be exact and true, but sans a compelling example that connects in multiple ways to your logic, your argument risks being a perfect, abstract thing: lovely to look at but without substance. Adding a juicy example to a paragraph is akin to scotch-taping a wolverine to the cover of this book.

4) Mixing up your sentence structure–One knock on scientific writing, besides the jargon (more on that later), is the interminably long, latinate sentences. Yet when constructing a logical argument full of if/then/or statements it is inevitable that the sentences can go on, and on, and on… The solution is not to go all Hemingway (unless you are really, really good). You know what I mean by that. Just spitting out a staccato series of noun-verb-noun sentences hoping that your reviewer doesn’t secretly enter you in some faux Hemingway contest. But you can mix it up a bit. Give your readers some opportunities to catch their breath as your brilliant logic rolls over them like the waves in From Here to Eternity.
5) Summary sentence. Sometimes your example is so stunning in its power that it will seal the deal. More often than not a strong summary statement is required. It serves two purposes. First, the summary sentence is your opportunity to introduce some repetition precisely where your reader is expecting it (remember: tell’em, teach’em, tell’em again). Second, the summary sentence can point the reader to where you want to go next. The best science writers do both in a single provocative sentence. In short, the topic sentence telegraphs your manuscript’s logic, but the summary sentence gives your manuscript its flow.
So when you’re working on your next essay, remember that the best manuscripts are built one paragraph at a time. Writing an effective paragraph is perhaps the single most important communication skill to acquire in your first years of grad school. It is a skill that the best scientists hone and one that we all universally admire. And that’s a big step toward getting your ideas out there.
