An English Literature instructor wants students to learn more about what influenced authors during the Great Depression. He assigns specific authors from that time period to students. He wants students to learn all they can about the author they have been assigned and then come together in groups to discuss the authors and how they are similar or different and how the Great Depression may have impacted their writings. Which method of indirect instruction was used

A case study is a method or process of studying a phenomenon through research and in-depth studies with its real-life context. This methodology of studying is done using real-life scenarios or even using real-life concepts into use.

In the given scenario, the English Literature instructor's desire to make his students learn more about the influence that writers during the Great Depression have is helped by making them do case studies. This means that the students are made to do studies on specific authors to make them understand more of the concept.

Thus, the correct answer is case studies.
