I read it in an article "How dare you say 'ain't' to me! I've taught you better than that." Is ' ain't ' not good to use in daily life? But I usually hear ' ain't ' in TV Show.
And about the slang,one of my teachers said that it was rude to say the slang so we don't need to learn it.What do you think of the slang?
Yes, you should be aware of slang and idioms. Depending on your age, you might use them, too.
Many of the problems ESL students face is their confusion when slang or idioms are used by others.

but it certainly doesn't mark you as being well educated
Pure piffle, Roger. All informal English is available to all speakers. If you were actually educated you would know more of the history of ain't.

Here's something I didn't know, Roger. Did you?
The usage of ain't in the southern United States is distinctive, however, in the continued usage of the word by well-educated, cultivated speakers. Ain't is in common usage of educated Southerners. In the South, the use of ain't can be used as a marker to separate cultured speakers from those who lack confidence in their social standing and thus avoid its use entirely.
