Explica la forma verbal (gramatica) "vosotros" por favor.
I am traveling to Spain for the first time in the summer. I've taken three years of Spanish coursework in college and I have not been taught when is the proper context to use "vosotros." My Spanish teachers say it's not popular in Latin America so don't worry about it.

Explica la forma verbal (gramatica) "vosotros" por favor. 
 I am traveling to Spain for the first time in the summer. I've taken three years of Spanish coursework in college and I have not been taught when is the proper context to use "vosotros." My Spanish teachers say it's not popular in Latin America so don't worry about it.

Answer

It's the plural of "tú" (second person singular).

Tú eres americano = You are American (singular)

Vosotros sois americanos = You are American(s) (plural)

In Spain, the words "tú" and "usted" are used when addressing people. Which one you should use depends on the situation. Their plurals are "vosotros" and "ustedes". I tend to use "usted" in formal situations or where politeness is required, or with older people. In most other cases I use "tú". When addressing a group of friends I would usually use "vosotros".

Answer

its the same than ustedes, solo que con vosotros tenes que usar vosotros tenes que cambiar los verbos como los dicen en España, vosotros trabajáis, ustedes trabajan.

Answer

Vosotros is informal where it's used and ustedes is formal.  In these areas, use vosotros when you would use tú but for multiple people (you guys), use "ustedes" when addressing a group of people with whom individually you would use "usted."

You'll probably be fine just using "ustedes" all the time, though.  I never use vosotros when talking with Spaniards who do use it, and while perhaps it sounds a little funny to them in informal situations, it's never caused any sort of communication problem.
