The student's observation about the position of stars is due to rotation of earth.

Explanation:

As we know that earth rotates around the sun and makes one complete rotation in 24 hours (completing a day). So the position and pattern of star always remains same, but it seems that star is moving across the sky because of our movement i. e earth's movement. The position of star differs every time as the position of observer is also changing constantly and unknowingly.
