Klustera- this is some kind of bolt for a door, since they used to have doorchains from the inside. So the question is, is this considered a kind of vessel or instrument that accepts tumah or not? So one Rav said that it is tahor, another said it is tamei, and Beruriah said that on Shabbos you're allowed to move it from one door to the other (meaning that it is not muktzeh.) R' Yehoshua, when he heard this, said "Yafeh amar Beruriah" meaning, "Well has Beruriah spoken."
So here we see that Beruriah is a) part of a halakhic discussion and b) is praised for her comment in this scenario. Not only is she learned, but she participates and her input is valued!
