What effect is likely to occur when teachers share positive experiences about an economics course?

The correct answer highlights that when teachers share positive experiences about an economics course, it tends to increase interest and enthusiasm for that course among potential students. Positive word-of-mouth acts as a form of promotion that can enhance the course's reputation, leading to more students wanting to enroll.

As more teachers communicate their enjoyment and the benefits they gained from the course, it effectively shifts the demand curve to the right, indicating an increase in demand. This phenomenon occurs because potential students who hear positive testimonials may perceive the course as valuable and beneficial, which makes them more likely to sign up. Consequently, the overall enrollment for the course is likely to rise, illustrating the direct correlation between shared positive experiences and increased demand.
