2.1 How to Summarize an Article

(Jackson & Stephens, 2024)

When you summarize information, you explain the most important parts of a source text in your own words. You typically summarize something to make it shorter. The page number is not required in the in-text citation for a summary.

2.1.1 An Effective Summary

Effective summaries do the following:

2.1.2 Here are some simple steps you can follow in order to create a summary:

Determine Your Purpose

The purpose of your summary will help you determine which details you should include. Typically, your summaries for academic writing have a similar purpose: you need to explain academic information without your opinion. You may also have a more specific focus in mind that will help you decide which details are important and which details you should not include in your summary.

Make a List of the Main Points

Example Quote:

"In 2020, 74 per cent of the global population used safely managed drinking water services. National estimates were available for 138 countries and four out of eight SDG regions, representing 45 per cent of the global population. Coverage was lower in rural areas (60 per cent) than in urban areas (86 per cent), which were home to two out of three of the 5.8 billion people using safely managed services. By 2020 a total of 84 countries had achieved universal (>99 per cent) coverage of at least basic drinking water services." (UNICEF, 2021, para. 3)

Example: List Main Points

A lot of details were left off the list because they were not essential for the summary. There is not one perfect way to make a list for your summary.

Example: Summary

Globally, 74% of the population has access to safe, clean water services, and cities have better water safety than towns and villages (UNICEF, 2021).

Notice how the items on the list are not just copied and pasted together into one big sentence. The ideas are connected together carefully. The order is changed a little and some of the ideas are condensed.

2.2 Academic Voice

(Brigham Young University-Idaho, Pryor, 2024)

Academic voice refers to the specific style and tone of writing commonly used in academic and scholarly contexts. Scholarly writing’s primary objective is to communicate clearly and concisely by using precise and inclusive language. It is characterized by its formal, objective, and authoritative nature, conveying a sense of expertise and professionalism. Academic voice is important as it helps establish credibility, clarity, and precision in conveying ideas and arguments. Here are some guidelines on how to use academic voice effectively.

  1. Third Person Point of View: Instead of using an I statement or a you statement, you will need to use a declarative statement. Declarative statements help relay information with precision.
    • Example of an I Statement: I read the article by Smith et al., (2020) and they found that diet and physical activity are correlated.
    • Example of a Declarative Statement: Smith et al. (2020), in their study with college students, found that diet and physical activity are correlated.
    • Example of a You Statement: Proper diet and exercise will help you be healthier and avoid chronic diseases.
    • Example of a Declarative Statement: Proper diet and exercise improves health and lowers the risk of chronic diseases.
  2. Objective Language: Use neutral and unbiased language, avoiding personal opinions, emotions, and unnecessary subjectivity. Focus on presenting evidence and arguments in a balanced manner.
  3. Formal Tone: Maintain a professional tone throughout your writing. Avoid colloquial language, slang, contractions, and overly casual expressions. Instead, use precise vocabulary and grammatically correct sentences.
  4. Clear and Concise Language: Strive for clarity and precision in your writing. Use words and phrases consistently with straightforward and specific language to convey your ideas effectively. Avoid excessive jargon, but include discipline-specific terminology where appropriate and ensure it is properly defined. If a certain length of paper is required, develop your arguments and include more research, and don’t add unnecessary words. 
  5. Citations and Evidence: Academic voice relies on supporting arguments with credible sources and evidence. Use appropriate citations to acknowledge the work of others and demonstrate the validity of your claims. Follow the APA style guidelines.
  6. Avoiding Informal Elements: Omit unnecessary elements found in casual writing, such as rhetorical questions, exclamation marks, and contractions. Instead, focus on logical and rational presentation of ideas.
    • Example of a Rhetorical Question: Wouldn't you feel better if you ate healthier and exercised more?
    • Example of More Formal Writing: Those who eat a balanced diet and exercise regularly report that they feel healthier.
    • Example of Contractions: Don't, isn't, there's.
    • Example of No Contractions: Do not, is not, there is.
  7. Avoiding Personal Anecdotes: Unlike personal or creative writing, academic writing does not typically involve personal anecdotes or experiences. Instead, prioritize objective analysis and scholarly discussion.
    • Example of Personal Anecdotes: Physical exercise is important because I have seen the difference it makes in my life!
    • Example of Non Personal: Physical exercise is important because it lowers the risk of chronic diseases (Smith et al., 2020).
  8. Sentence Structure and Grammar: Maintain a clear and coherent structure in your writing. Use grammatically correct sentences, varied sentence structures, and appropriate transitions to ensure your writing flows smoothly.
    • Example of Poor Sentence Structure: So, as you can see from above, the findings are positive and relate diet and exercise together.
    • Example of Good Sentence Structure: These findings by Smith et al., (2020) and Lu et al., (2022) make a positive correlation between diet and exercise. Those who exercise more consistently also tend to consume a more balanced diet.
  9. To create continuity in your writing, use links that cue the reader about the information you present, such as the following:
    • Time Links: After, next since, then, while.
    • Cause and Effect Links: As a result, consequently, therefore.
    • Additional Links: Furthermore, in addition, moreover.
    • Contrast Links: Although, but, conversely, however.

2.3 How to Write a Literature Review and Introduction

(Brigham Young University-Idaho, Pryor, 2024)

An Introduction is a three-to-four-page paper addressing the research question and study you designed with your group. 

​​Students commonly believe that they can sit down and author an academic paper start to finish in one attempt, but experienced writers know this is not the best approach to writing a complex paper. Thankfully, you have already taken several steps to prepare to write the Introduction section of your paper. The next step will be to plan what you will write. This plan is called an outline.

The goals of an Introduction is to:

2.3.1 Writing Process

Where to Begin: The Background Section

The following is the recommended writing process:

Example:


Example of the background section. For an in-depth description, see the appendix.

Access the appendix for a description of the image. 

Next: The Motivation Section

Based on your Background section, write your Motivation section. Highlight your hypothesis and why it matters. 

Finally: Your Topic Paragraph

Now that the bulk of your paper has been written:

  1. Scan the text for key terms that are unknown to your professional audience. Develop a definition of them in your own words using the sources. 
  2. Identify the basic statistics that demonstrate the importance of your research question. These could include the incidence, prevalence, cost, or other impact of the topic.
  3. Give hints to your reader about what they should expect to read in the rest of the paper. 
  4. Incorporate these into the draft paragraph you wrote in your planning phase.  

You will now have an unformatted rough draft.

2.4 What is the IRB?

(Brigham Young University - Idaho, Pryor, 2024)

In the United States, most researchers are required to get their research approved by an Institutional Review Board (IRB). IRBs are located at universities and other facilities that participate in research projects. Most other countries also have some sort of IRBs. IRBs review research studies to ensure that they comply with regulations, meet ethical standards, follow pertinent policies, and protect research participants. The IRB originated due to poor practices of researchers who were conducting research on participants without their full consent, or without informing them of the consequences of the research. An example of this is the Tuskegee Syphilis Study that was conducted in the 1940s. Researchers asked disadvantaged, rural black men to participate in a study about syphilis. The researchers wanted to see what would happen when syphilis went untreated for many years. During the time of the study, penicillin was found to be an effective means to treat syphilis. Unfortunately, the researchers decided that they would not give the men in the study the treatment so as to not interrupt the project even long after the treatment was available. These men would have had a better life outcome if treatment would have been provided.

There are three basic ethical principles that the IRB strive to protect, these include:

  1. Respect for Persons: Individuals should be treated as autonomous agents (meaning they can make their own decisions) and persons with diminished autonomy are entitled to protection (such as children under the age of 18 or disabled persons).
  2. Beneficence: Researchers should make efforts to secure the participants' well-being. 
  3. Justice: Research subjects should be taken from a variety of persons, not just the disadvantaged. Advantages gained from research should be available to all.

In order to get a research project approved by the IRB, a researcher must undergo training and then submit his or her research proposal to the IRB for approval. The process can take anywhere from two weeks to multiple months depending on the nature of the research. 

Since we will only be surveying other classmates in the course, we do not need to ask the IRB for approval.
