It is important for students to understand various communication principles and be able to apply them in a variety of settings using critical thinking skills. Students must learn how to think critically, which includes the ability to apply, connect, analyze, and evaluate information. Teachers, instructors, and professors who are able to integrate these types of critical thinking skills in the classroom have reported "an increase in their teaching pleasure: classroom discussions are richer, students are more fully engaged in their learning, and the quality of their performance improves." Using a murder mystery provides an alternative method for the demonstration and application of communication concepts. Additionally, this exercise is a creative way for students to express themselves through role-playing while practicing communication principles such as nonverbal communication, group/team skills, listening, and perception. Role playing "can be used in a variety of classes and facilitates active involvement, provides a concrete basis for discussion and helps relate knowledge to students' experiences."
