This is really difficult to explain without sitting in front of you with a globe and a mock solar-earth system, so you can see the actual field of view.
Because the Earth is tilted on its axis with respect to its orbit, and because the Earth is rotating, you actually get a larger than 180 degree field of view if you count the entire nights viewing. In addition, unless you are on the equator, your night sky won't change all that much as you go around the sun.
If you are in the northern hemisphere the stars directly above the axis of rotation (North Pole) will always be due north. That is why Polaris never changes, no matter the time of day or the season. Those stars around Polaris also stay relatively the same throughout the night and the seasons, but as you go further away from Polaris the variance increases. Nevertheless, you get a lot more of the sky than you might think (if you think of all the sky you see throughout the night), You just see different constellations (further away from Polaris) at different times of the night depending on the season.
Far away from the North Star (assuming you are in the northern hemisphere) things do change up quite a bit as the seasons change. There are some constellations that the Northern hemisphere people will never see (Southern Cross e.g.) and the same for the Southern Hemisphere.. On the equator you get the most variation in the night sky, getting to see all the constellations that everyone sees, but for less of the time each year. The further you are away from the equator the less variance you will see. At the pole for example, the stars never change, though since you can't even see them for several months in the summer, its difficult to realize that during that time.
Here is a video that might help you understand, though it really isn't great. If I find a better one I will share it with you so you can understand orbital field of view on a tilted rotating sphere in orbit around a shining object (the sun) that obfuscates the sky half the time.
