“…A case study is a "story with a hidden message or a narrative that describes an actual or realistic situation in which an individual or a group has to make a decision or solve a problem" (Killen, 2006, 275). Case studies increase students' motivation and their interest in subjects (Mustoe and Croft, 1999), stimulate dialogue (Badger, 2010), link between theory and practice (Olkun et al, 2009), encourage deep learning, promote interaction between teachers and students, make learning more enjoyable (Ngcobo, 2008), and promote the development of analytical skills by students (Herreid et al, 2011). Case studies can be formal written cases, newspaper articles, movie clips, media news story, pictures, mathematical word problems, pieces of art, or any other (Golich, 2000).…”
