The shiur has been a primary method of teaching since Mishnaic times. In a famous Talmudic passage, RabbiJudah haNasi averred that he gained his sharp mind from watching Rabbi Meir deliver the shiur. However, since the lecture hall was so crowded, his seat was behind the lectern, so he only saw Rabbi Meir from the back. "Had I seen him from the front, how much greater would I have become!" he declared.
Yeshiva learning
Traditionally, a shiur refers to the type of learning that takes place in yeshivot and kollelim, in which students hear an in-depth lecture on the sugyathe yeshiva is studying at the time. Typically, yeshiva students attend a daily shiur yomi given by a maggid shiur and a weekly shiur klali given by the rosh yeshiva.The rosh yeshiva usually also gives the top shiur on a daily basis. Before the shiur, a bibliography and a series of textual references are posted so that students may prepare for the lesson in advance. Students typically spend several hours preparing for the shiur yomi. After the shiur, students spend additional time reviewing and clarifying the lesson that they have just heard. These preparation and review periods take place in a special time period called a seder, in which students study the lesson individually and/or in chavrutot. Shiurim may also be offered in yeshiva on topics in mussar, Chumash, and hashkafah, depending on the yeshiva and the learning level of its students.
Class levels
A shiur is also the name given to the different class-levels in a yeshiva. For example, first-year students are said to be in "Shiur Aleph"; second-year students are in "Shiur Bet"; third-year students are in "Shiur Gimmel, etc. In kollelim, the higher shiurim accommodate more advanced levels of learning. See Yeshiva #Talmud study.
rabbis and noted rabbis in the community also give shiurim to their constituencies. In shuls, the shiur given between Mincha and Maariv is usually geared to baalebatim. Noted rabbis give more in-depth shiurim to attendees on Shabbat or weekday evenings, usually in the localsynagogue or beth midrash.
Modern use
In modern parlance, the term "shiur" has been extended to include any kind of Torah lesson — including lectures to children, women, and baalebatim, and taped lectures circulated via cassette tape, computer hookup, MP3 or MP4connection, or call-in telephone lines. Though by definition, a shiur is a comprehensive, structured lesson, some kiruv organizations advertise "five-minute shiurim" to attract beginning listeners.
