What's the difference between study tour, study tour and study tour?

Study tour: Students (or adults) use their holidays to go to other countries or regions to learn all kinds of knowledge and skills, so as to realize the purpose of self-charging during holidays.

Research: Expand textbook knowledge into reality, and learn and experience book content in travel scenes.

Study tour: the synonym of study tour is a new word coined by a few study tour institutions to highlight the difference between their own projects and traditional travel tours, and it is not universal.
