To cite your sources, you'll need to gather these pieces of information:
Ma Lei, Hsieh, et al. "Four Pedagogical Approaches in Helping Students Learn Information Literacy Skills." Journal of Academic Librarianship 40.3/4 (2014): 234-246. Academic Search Complete. Web. 29 Jan. 2015.
And, you will need a resource for the citation style required by the assignment.
What is a citation style? Basically, it's a set of rules about how to organize and punctuate these pieces of information when citing a source, agreed upon by a professional organization (e.g. MLA style was created by the Modern Language Association; APA style by the American Psychological Association). Different styles, different professional organizations.
