What action should instructors take when adjusting heating and air conditioning systems?

Instructors should make adjustments in advance for temperature changes to ensure a comfortable learning environment for students. This proactive approach allows instructors to account for external factors such as weather variations, the number of students present, and the activities planned for the session. By setting the heating and air conditioning systems ahead of time, instructors can help to create an optimal atmosphere that minimizes distractions and fosters better focus and participation during the lessons.

This strategy not only enhances comfort but also demonstrates professionalism and consideration for students' needs. Waiting until students arrive to assess comfort may lead to delays and possible disruptions, while setting the temperature cooler or warmer than expected without prior adjustments could result in discomfort and detract from the learning experience. Making adjustments in advance reflects good planning and awareness of the importance of a suitable classroom environment.
