Family Planning NSW: Contraception Choices and Effectiveness

Next steps

  1. Determine your keywords to use for research (e.g. "oral pill" "effect OR impact" "prevent pregnancy").
  2. Use OneSearch, the Science Databases and scientific websites (middle columns on this page) to gather scientific evidence.
  3. Read, evaluate sources (CRAAP test in third column on this page) take notes, process and think.
  4. Pose a research question addressing an aspect of the claim (see third column on this page if you are not sure how to do this).
  5. Do more research to delve deeper. Find data and facts to support your ideas but take note of any limitations of the research. Refine your research question as your knowledge and understanding deepens.
  6. Make sure you are building a reference list (MyBib link in third column on this page) and in-text referencing your sources used as you structure and write your report.

Google Scholar's searches are set to cover scholarly material more often than 'regular' Google. Google Scholar's searches are set to cover scholarly material more often than 'regular' Google. It can be frustrating, as much of an article or book is missing or by purchase only. Read the article below on the advantages an disadvantages of using it.

TIP: To get PDFs only, type in 'filetype:pdf'. It's great!

Advantages / Disadvantages of Google Scholar 

How to use Google Books

Google Books can be very frustrating because often much of the book is missing and you are expected to purchase it to read the full content. So after you put in your search term you are interested in (eg biodiesel), and get some results up,  you should then go immediately to the search box (on the left - above 'About this box') undefined and type in a particular word or term you are interested in (eg CO2 emissions OR methanol) you should get a number of pages pop up. Choose one that looks useful - you should get some good results this way!

Developing a Research Question

Research Question is defined as ‘A question that directs the scientific inquiry activity. Its purpose is to focus the research investigation, inform the direction of the research, and guide all stages of inquiry, analysis, interpretation and evaluation’. It should:

1.3.1 Include measurable variables – the independent and dependent variables

1.3.2 Have a guiding word, such as what, why, would or will

1.3.3 Be phrased so that a definitive answer can be developed

1.3.4 Be able to link the guiding word to verbs such as identify, describe, compare, contrast, distinguish, analyse, evaluate or create so that a specific task can be determined


Should patients over the age of 80 years be permitted to undergo triple bypass operations? (Too broad)


Should triple bypass operations (independent variable) be offerered to patients over 80 (participant group) because of their poorer success rate regarding complications from pneumonia and stroke (measurable dependant variable) compared to patients under 80 (comparison/control)
