I can't wrap my head around resizing/resampling and what is the right way to do it (CS5)

I know it's probably pretty basic, but it escapes within my reach at the moment.  for some reason, my teacher never really went over this other that say 300 DPI was what you want to get better quality prints, so I have always just sort of worked with this in mind, and has never required much account "resampling" or that he was necessarily, box was just always checked.  im not sure how, or if, I myself was screwing all this time and I know that's not THAT hard so any advice would be appreciated.  and I apologize if this has been exceeded to death, but I wanted to use an example to help understand better (I hope).

Oh and most of my work I display on the internet, with the idea that it will be printed in the future, or with the idea that she can at least be printed.  I heard about the web, all you need is 72 dpi, but since I expect to be printed I just made 300 DPI and save normally.  It of a bad move on my part and I'm missing something by saving does not 'for the web and devices '?

example:

Screen shot 2014-05-04 at 5.01.20 PM.png

so I have an image I downloaded on the internet.  as you can see, it is at 72 dpi and near 12.7x17.7in.

Let's say I want to enlarge to a same 13 inches and increase the resolution to 300 dpi.

I'm confused that when I want to uncheck resample.  Since it blocks the pixels, if I increase the resolution the image gets more small and vice versa.  I don't know that I have enter when it's advantageous to have unchecked resample.

I feel really stupid, because I know this is pretty noobish, but we have barely touched on this and the ability to save for web and devices (not at all) in my design class.  Thanks for any help.

Resizing is only this; It resizes the image while keeping the number of pixels. Resampling is adding an option to change the number of pixels in the image.

As a general rule, you'll want to leave resampling of the equation when printing it is mainly used for the screen (monitor) watch one.
