Students in years 7-12 are required to include a reference list with submitted assessment tasks.
Your reference list needs to reflect the APA referencing style.
When to include a reference list?
Whenever you use ideas / examples / evidence in an assessment task that you did not think of yourself, and thus those ideas / examples / evidence do not belong to you.
How to structure a reference list:
Your reference list must be in alphabetical order according to the author's surname or by organisation.
Write the reference list on a new page at the end of your assessment task
You need to individually reference each source/site that you have used. The way that you structure each reference depends on the TYPE of source/site. EG. If you got ideas of of a book, a website, and a reserach article you have to structure each reference differently because they are different types of sources
You can find a reliable APA referencing guide here which outlines how to structure references for different types of sources
You can also use pages 30-31 in your diary, also found HERE
