Keywords are the building block of research. By identifying the best keywords, you maximize the number of relevant sources you find!
One thing to keep in mind when you are doing research on your topic is that there is NO SUCH THING as a single perfect source that you will be able to cite to support your thesis. Researching and writing is a process of learning about your topic, thinking critically about what you've learned, and supporting your thesis through referencing a variety of sources.
Make a list. Check it twice! (Don’t know anything about keywords? Watch the :Keywords: A Quick Guide" video on this page!)
Here's an example.
My topic is "Text messaging is harmful to teen literacy."
My keywords in this topic are "text messaging" and "harmful", "teen", and maybe "literacy". (We will discuss that last one in a minute!)
My "related words" lists might look like this:
Now I can mix and match - pick two or three words from different lists and use those as my initial search.
Sometimes you have tricky words like literacy. There's no one word that means the same thing, but you can make PHRASES out of other words, like combining "reading" and "proficiency" to make a key phrase: "reading proficiency".
