Does Amherst teach modern music production like studio production, mixing, recording, usage of laptop for production, etc?
It depends on what you mean by “teach”. There is an audio recording studio located in the Math and Computer Science building with posted hours for instruction by a music professor in how to use the equipment. But, but, it’s a one off session that lasts only for a few hours and (I think) presumes a certain amount of prior experience:

For a true course in music recording you may want to check out Wesleyan:
