The document provides guidance on how to teach an effective first day of class. It outlines four key principles: 1) foster curiosity, 2) create community, 3) engage in learning, and 4) set expectations. For each principle, specific strategies are suggested, such as sparking student interest in course content, getting to know students individually, asking students to complete a cognitive task, and reviewing course policies and assignments. The document also recommends preparing for the first day by learning about students in advance and ensuring any technology works properly. Following the first day, instructors should summarize key points and student work for the next class to build on initial lessons.
