Prelude to the Case

In this “clicker case,” students read about a murder committed in Wales, then learn about DNA structure and replication and how scientists have adapted these concepts to develop processes for use in forensic analysis. The students use this knowledge to identify possible suspects in the crime.

This case is called a clicker case because it was designed to be presented in a class that uses personal response systems, better known as “clickers.” The case study is presented in class via PowerPoint, with multiple-choice questions sprinkled throughout the “lecture.” Students are expected to answer the questions as they arise using their clickers. Many instructors allow students to consult with their neighbor before clicking in their answer. The entire approach encourages student participation even in the largest of classes. The use of clickers in combination with case studies is described in greater detail in the article “Clicker” Cases: Introducing Case Study Teaching Into Large Classrooms.
