What is a significant instructional element that influences perception?

The significant instructional element that influences perception is personal appearance. This is because the way an instructor presents themselves can heavily impact how students perceive their authority, professionalism, and engagement level. An instructor’s attire, grooming, and overall presentation can create an initial impression that affects students' attitudes toward the course and the instructor’s credibility.

For instance, instructors who dress appropriately for the setting and demonstrate good hygiene often instill a sense of respect and seriousness about the course material. This visual cue can help establish an atmosphere conducive to learning, where students feel more inclined to engage and participate actively. Thus, personal appearance can be a powerful factor in shaping students' perceptions and, subsequently, their willingness to absorb the material being taught.
