Tutorial on Grammar
​in Scientific Writing

Grammar defines what a sentence is, what it is not, and what it can be. For an engineer or scientist, understanding grammar is important not only to avoid errors that can undermine one's credibility, but also to gain a foundation for understanding strategies at the sentence level to connect ideas and emphasize important details. Sadly, around 1970, a flawed educational movement in English-speaking countries persuaded many schools to stop teaching grammar [1-3]. This concise tutorial, which attempts to bridge that gap of knowledge, has the following goals:
  1. give you a grammatical foundation so that you are certain whether a group of words that you have written is a sentence; 
  2. define the essential terms of grammar so that you cannot only analyze your own writing but also provide valuable comments to colleagues on their documents; and
  3. teach you effective strategies in scientific writing for connecting ideas and emphasizing details at the sentence level.

1. Take Grammar Diagnostic

The following four questions test your practical knowledge of grammar. Answer the four questions and the check your answers in the paragraph below. If you struggle with these questions, then you should consider completing the tutorial.
  1. Identify whether the following group of words is a sentence, a run-on, or a fragment: An oval shape is necessary in the die cavity, otherwise, the flow of metal would be affected.
  2. ​Identify whether the following group of words is a sentence, a run-on, or a fragment: In the family Giraffidae, modern-day giraffes are one of only two remaining species left, the other being the endangered okapi.
  3. ​Identify the grammatical subject of the following sentence: To gather data about our target customers, we examined customer reviews of the product on Amazon.com.
  4. Provide an example of an infinitive phrase.
Recognizing and correcting errors is an important part of understanding grammar. The first two questions test your recognition of whether a group of words is a sentence. The first item is a run-on, while the second is a grammatically correct sentence. In addition to knowing what a sentence is and is not, you should also know grammatical terms so that you can master important strategies in scientific writing such as connecting ideas in paragraphs and relying on active voice, Understanding such terms also allows you to make concrete comments about the documents of your colleagues. One such term is the subject of a sentence, which the third question asked you to identify.  In that question's sentence, the subject is we. The fourth question asks for an example of another important grammatical term in scientific writing: the infinitive phrase. Such an example would be "to measure the velocity." As this tutorial will show, an infinitive phrase is a valuable sentence opener in scientific writing.
