Want to know how to write an introduction/background section of a paper? Pay attention to STRUCTURE & evidence-based ARGUMENT in order to DIY (do-it-yourself) your own intro/background for a school paper or research report!
Focus only on the INTRO/BACKGROUND section for now. Check out the STRUCTURE then the EVIDENCE-BASED ARGUMENT of the Intro/Background. This is how you should write your own.
STRUCTURE of INTRO/BACKGROUND in Sørbø et al. (2015):
Where is the Intro/Background section located in the article?
What heading is used for the section?
Where are the research questionslocated in the Intro/Background? (HINT: this is the standard place in all papers & in this case the authors call them “aims.)
ARGUMENTS in INTRO/BACKGROUND in Sørbø et al. (2015):
Look at the first (topic) sentence of each paragraph in INTRO/BACKGROUND & listen to the systematic argument the researchers are making for WHY their study is important.
“Breast feeding has long been acknowledged as the optimal infant nutrition conferring beneficial short-term and long-term health effects for both infants and mothers.1–5 …
Abuse of women is common worldwide, as one in three women during lifetime suffer partner or non-partner abuse.10…Adverse effects [of abuse]… are barriers to breast feeding.*…
Given the overwhelming evidence of the positive effects of breast feeding, knowledge about factors influencing breastfeeding behaviour is essential….
We explored the impact of abuse of women on breastfeeding behaviour in a large prospective population in Norway where the expectations to breast feed are high, and breast feeding is facilitated in the work regulations….” (pp. 1-2)
Now look at the research & other evidence written down AFTER each of above key sentences that SUPPORT each idea.
Notice that the INTRO/BACKGROUND is NOT a series of abstracts of different studies!! Instead evidence is grouped into key arguments for the study: Breast feeding is best, Abuse is common, Abuse creates barriers to breastfeeding, & Therefore, knowing about factors affecting breastfeeding is important). [Note: Of course, if your particular professor or editor asks you to do a series of abstracts, then you must, but do group them in arguments like the topic sentences.]
All this leads naturally, logically to …(drum roll please!)…the research questions/hypotheses, which are the gaps in our knowledge that the research will fill. This sets up the rest of the research article!
Critical Thinking: Your turn! Write your own Intro/Background using
Structure:Placement in article, heading, placement of research question/hypothesis
Argument:Key idea topic sentences (make a list 1st) with supporting research & other evidence (your literature review).
How strong is the evidence regarding our holiday Santa Claus (SC) practices? And what are the opportunities on this SC topic for new descriptive, correlation, or experimental research? Although existing evidence generally supports SC, in the end we may conclude, “the most real things in the world are those that neither children nor men can see” (Church, as cited in Newseum, n.d.).
Critical thinking: Check out this related research study with fulltext available through PubMed: Black Pete through the eyes of Dutch children
(https://www.ncbi.nlm.nih.gov/pubmed/27322583 ). Write a follow-up research question based on the findings of this study & post in comments below.
For more info: For those unfamiliar with ResearchGate, it is a site where you can track authors who publish in your area of interest, and you can set up your own profile so that people can track your work. Take a look.
Google–not to mention yahoo, bing & other web search engines–are mere popularity contests of literature. Google Scholar is a step up, but it is still a search engine. It can miss important articles entirely.
If you want to be sure that you are getting the BEST, you gotta look in the right place if you want to find the right articles on the right topic at the right time!
Reputable publishers give away very few articles for free, so when you want the best literature out there you need a Database that will systematically help you to find quality articles that fit your topic.
PubMed.gov is a tax funded database that is highly comprehensive. CINAHL is strong on nursing literature. If you are enrolled in a university, you have access to lots of full-text articles at no added cost. Check with your librarian if your database search is not turning up what you need–with a few hints, you could get the best.
[After watching video: Note that the variable that is controlled by the researcher is call the Independent variable or Cause variable because it creates a change in something else. That something else that changes is the Dependent variable or Outcome variable.]
Based on the video, can you explain why true experiments are often called randomized controlled trial (RCT)?
