Final answer:
The truth of master students avoiding the phrase 'I can't' varies individually, but in the context of Jeremy Iversen's book, it highlights the impact of negative labeling by teachers on student self-perception and the potential to embrace limiting beliefs.
Step-by-step explanation:
The statement about master students tending to avoid the phrase "I can't" and its variations does not universally hold true or false, as it would depend on the individual's mindset and teachings they have encountered. However, considering the context provided from Jeremy Iversen's book High School Confidential, the question seems to address the issue of self-fulfilling prophecies in educational settings rather than the habits of master students specifically.
In his book, Iversen observes the detrimental effects that negative labeling by teachers can have on students. When students are told by authority figures that they lack potential or ability, they may internalize these beliefs, which could lead to a phenomenon known as "living down to" the label. This suggests that students' avoidance of phrases like "I can't" could be influenced by the expectations and feedback they receive from teachers and the school environment.
