Chavrusa, also spelled chavruta or havruta (Aramaic: חַבְרוּתָא, lit. "friendship" or "companionship"), is a traditional rabbinic approach to Talmudic study in which a pair of students analyze, discuss, and debate a shared text. It is a primary learning method in yeshivas and kollels, where students often engage regular study partners of similar knowledge and ability, and is also practiced by men and boys outside the yeshiva setting, in work, home and vacation settings.
I started wondering about this because The Course in Buddhist Reasoning & Debate was released today. I began wondering about similar resources in other traditions.
