Primary Sources Starter Pack for Teachers: The Information Cycle

Because every Subject has a History

Just what ARE primary sources?

Information has a cycle starting from the moment an event happens. Teach this cycle to your students and it will help them understand how a primary source differs from a secondary source...and when they might want to use one over the other as they grapple with understanding the context of their subject.  

 

PRIMARY - SECONDARY - TERTIARY

Information after an event travels in a progression from
primary sources: “I was there” (diaries, letters, posters, photos, etc) to:

secondary sources: “I wasn’t there, but I am talking to or reading about someone who was there” (magazines, newspapers, books).
to:

Scholarly sources:I study primary sources to understand what happened" (peer reviewed journals, etc)
to:

Tertiary sources “We have studied this event and are writing to give you an overview of what happened and the effects afterwards” (encyclopedias, subject series, etc).

Items that were written at the time of the event such as newspapers are secondary sources at that point...but can become primary sources later as researchers study the newspaper as a product of its time.

Here it is: the information cycle
