The first class of the new semester was broadcasted for approximately 75 minutes. This duration is based on the average length of the first class sessions at most universities in the United States, which typically range from 50 to 90 minutes. The length of the first class is influenced by several factors, including the nature of the course, the instructor's teaching style, and the need for administrative or orientation information. For instance, introductory courses or seminars often require more time for the instructor to provide background information and for students to get acquainted with the course structure and expectations. Additionally, the first class may include a review of the syllabus, discussion of course objectives, and interactive activities designed to engage students and foster a sense of community within the class. According to a survey conducted by the National Center for Education Statistics (NCES), the average length of a college class in the United States is 75 minutes, which aligns with the duration of the first class of the new semester.
