Lain Iwakura's homeroom teacher, is a minor character who appears in episode 1 and episode 8. She has very few lines.

Her name, Yoshii Keiko (吉井恵子), is only known because it appears in the credits.

Serial Experiments Lain @wiki mentions her on this page (Japanese).

Originally she was planned to be a supporting character, hence she was given a name in the first place. This was dropped however, and she became a background character instead.
