What are the main source texts for the chavruta and teacher-student models in Jewish learning?

Question

I'm working on an outline for a short presentation on how new online tools, especially this site, interact with the traditional Jewish learning models of chavruta and teacher-student. What are the main source texts (I suppose mostly in the Talmud, though some may be earlier and later) for the roles and benefits of these two models and the interplay between them? If there's a particular commentary or contemporary source that sums up traditional understandings of any of these primary sources, that would be great to have, too.

Answer 1

A few raw blobs off the top of my head.

• The Gemara has "Cherev al haBadim" -- a curse on those who study all alone. I heard one rosh yeshiva say that means you always need a chavrusa ("and I even asked my chavrusa to come to my house during sheva brachos week so we could learn"); and another who said that means you can study alone, but every so often compare with others ("some people even send a chavrusa to the house for sheva brachos! What kind of nonsense?").

• Choni Ham'agel's "oh chevrusa o misusa."

• Shaul Stampfer's work on the 19th-century yeshiva says it appears in Volozhin (at least at one point), a chavrusa would be for a weaker student if he needed help; most studied alone.

• Gemara in Sanhedrin that in Babylonia "mechablim zeh et zeh bahalacha", ("we beat each other up arguing over halacha"), whereas in Israel "man'imim zeh et zeh" ("we support each other pleasantly." I once witnessed this with two Israelis, one going, "I'll take what you're saying one step further", and the other "I'll take what you're saying one step further", even if that wasn't what was intended!)

Answer 2

I don't know if this is what you are looking for, but the famous story surrounding the death of Reish Lakish (bottom of Bava Metzia 84a) plays out the benefit of a proper chavrusaship. A translation is here.

R. Yochanan was upset following Reish Lakish's death, and the rabbanan sent R. Elazar b. Pedas to learn in Reish Lakish's stead. R. Yochanan felt the chavrusaship was unproductive, since R. Elazar merely supported (textually) everything R. Yochanan said. With Reish Lakish, R. Yochanan had to defend his position and this allowed a broader understanding of the halacha.
