In the context of Artificial Intelligence in Education (AIED), teacher avatarization is the process of transforming the dataset produced by one concrete human teacher (or a precisely-defined group of human teachers) into a multi-modal generative artificial intelligence system with which future generations of learners can seemlessly interact.

 "descent of a Hindu deity to earth in an incarnate or tangible form," from Sanskrit avatarana "descent" (of a deity to the earth in incarnate form), from ava- "off, down" (from Proto-Indo-European root *au- (2) "off, away") + base of tarati "(he) crosses over" (from PIE root *tere- (2) "cross over, pass through, overcome").

The meaning "concrete embodiment of something abstract" is from 1815. In computer use, it seems to trace to the novel "Snowcrash" (1992) by Neal Stephenson.

Within the "idealist" philosophical tradition, it is not necessarily the physical person but rather a "pure idea" (e.g. protection, justice, wisdom, friendship etc.) which is to be "avatarized".

"I"-Avatarization is the process whereby a living human H consciously creates, develops, fine tunes and optimizes (his|her) own generative AI avatar datasets & models.

That is, using datasets (mails, chat transcripts etc.) to create a generative AI copy of one's self (an "I-Avatar") which could provide information in situation when H (her|him)self is not alive anymore.
