"Science Teacher" isn't a real Magic: The Gathering keyword or ability—it doesn't exist in the game's rules or on any official card. You may be thinking of a different mechanic, a custom/joke card, or perhaps mixing up terminology.
If you're looking for something similar, there are real creature types and mechanics worth exploring. For instance, "Professor" appears as a creature type in the Strixhaven: School of Mages set, which is themed around a magical university. Cards there feature mechanics like Learn (letting you grab Lesson cards from outside the game or rummage) and Magecraft (triggering whenever you cast or copy an instant/sorcery).
If you can clarify the actual card or ability you meant—or if it's from a custom set on Mythicwyrm—I'll gladly break down exactly how it works and where it shines in Commander.
