Explanation:

Moving the mirror away from the screen:
- By moving the concave mirror away from the screen, the student can obtain a better value of the focal length of the mirror.
- When the mirror is moved away from the screen, the image distance increases, making it easier to accurately measure the focal length.
- This adjustment allows for a clearer and more precise image formation, leading to a more accurate determination of the focal length.
Therefore, the correct option is to move the mirror away from the screen.
