Why does Instagram ruin the quality of my photos?

When I post my photos, they are clear and they're the way I want them to be. But a few minutes later when I check my photo again, I can see some pixels/squares. Instagram ruined my photo!

I'm a photo student and my teacher tells us that the internet tends to ruin the quality of your photos if you do not resize them. For example, if a 300 resolution photo is uploaded on Facebook, Facebook cannot handle the high resolution and they shrink it, but they end up damaging the photo.So my teacher recommends we resize it to a 72 resolution photo and no bigger than 10 inches.

So my problem is, even though I resize all my photos and then upload them to Instagram, Instagram usually ends up making my photo look a bit pixelated! The annoying thing is, sometimes my photos would remain clear, while others get ruined (and they're the same resolution).So I cannot understand what's happening and why! Is there a specific resolution my I should make my photos in Photoshop for Instagram to prevent this problem?

I have a Nikon Coolpix L810 and a LG Optimus Elite if that helps.
