Dear _____,
I'm writing to complain about a teacher's behavior in our class. Teachers have a significant impact on our lives. Teachers assist students in thriving in their learning by teaching them new or more complex academic curricula, as well as teaching and reinforcing desired behavior. Adolescents are adults in training who look to their teachers for guidance in becoming civil members of society. However, as a result of the impact of bad teachers, many diverse communities are feeling the impact of bad teacher behavior, with rising classroom incivility. This letter, however, is not intended to belittle or diminish teachers' integrity; rather, it is a letter that illustrates the effects teachers have on adolescents using a variety of scholarly sources.
respectfully,
