This work discusses the design and implementation of two online case studies in a face-to-face general chemistry course. The case studies were integrated into the course to emphasize the need for science literacy in general society, to enhance critical thinking, to introduce database searching, and to improve primary literature reading skills. An online social networking platform was chosen to take advantage of commonly used modes of conversation in the young adult population. Facebook was selected as the case study platform because of its functionality, popularity, and group capabilities. Details on the execution of the case studies on Facebook and corresponding student feedback are included.
