Why is it advised not to start a class with apologies?

Starting a class with apologies can significantly undermine your credibility as an instructor. When an instructor begins with an apology, it may convey a lack of confidence or authority, leading students to question the instructor's competence and knowledge. This can disrupt the perception students have of the instructor's leadership and expertise, which are crucial for an effective learning environment.

Establishing credibility is vital in any teaching scenario, as students are more likely to engage and respect an instructor who presents themselves with confidence. Instead of setting a tone of professionalism, an apology can shift focus away from the content and more toward the instructor's insecurities. This can lead to a less productive class atmosphere, where students may not fully absorb the material being taught.

While issues such as wasting class time, causing discomfort, or leading to confusion can be factors to consider when starting a class, the primary concern remains the negative impact on the instructor's credibility, which is central to effective teaching and learning.
