New students learn to ________, sit in seiza, refer to Sensei, and enter/exit.

The focus on learning to bow is central to martial arts training and etiquette. Bowing serves as a sign of respect and humility, which are key values in many martial arts disciplines. It is an essential part of the training ritual that acknowledges the presence of instructors and fellow students, helping to foster a respectful environment conducive to learning.

In addition to bowing, students are taught the importance of proper stance, sitting in seiza (a traditional Japanese sitting posture), addressing the Sensei properly, and the etiquette involved in entering and exiting the dojo. Together, these practices help new students become accustomed to the customs and courtesies of martial arts training, establishing a respectful atmosphere within the dojo.

The other choices, while relevant activities in martial arts, do not carry the same weight of tradition and respect that bowing does in the context of a dojo environment. Thus, mastering the act of bowing is a fundamental part of the introductory learning process for new students.
