In this lecture, we start to get more specific about what a cover letter, its purpose and its elements. We explore the characteristics of a good cover letter and a bad cover letter in more detail. In particular, students are given sample cover letters and are asked to study them in groups. Then, the students describe each of the cover letters and categorize their characteristics into things that should be included in a cover letter and things that one should not include. The purpose is to give the students tools to be able to constructively criticize their own cover letters and improve them.
