We need to acknowledge all sources referred to in our assignments, even if it was just an idea or concept. This is not optional at University. It doesn't matter if you quote, paraphrase or summarise - you need to acknowledge where the idea came from and cite/reference it in the correct referencing style for your faculty. See QUT cite section of
www.citewrite.qut.edu.au for interactive details and examples of how to cite each type of resource e.g. book, YouTube clip, online journal according to QUT APA, QUT Harvard, QUT Legal and QUT Numbered styles. Find out what style your faculty uses. Also, see p27 of the QUT Cite Write book for examples of integrating sources into sentences.
