Final answer:
To address students talking during a demonstration, the instructor should engage them by asking if they have questions and use non-verbal cues to regain control of the classroom environment.
Step-by-step explanation:
The instructor should address the issue of students talking during a demonstration in a classroom setting. One effective approach is for the instructor to ask the owners if they have any questions she can answer. This method directly engages the talking students and can redirect their attention to the subject at hand. Additionally, the instructor could utilize non-verbal cues, read body language, and encourage the students to express their thoughts or concerns about the lecture material in a more appropriate time. It is important for the instructor to maintain social control and ensure a respectful learning environment for all students.
