Here are a couple links on how to host reading and writing conferences with students:
Reading Conference: This link describes the power that a reading conference can have on a child. It talks about the logistics of conferencing, how to keep record of what has been discussed, and assessing the students’ choice reading.
Reading and Writing Conference: This link describes the what, when and how of conferencing for both reading and writing. It also explains that the student should leave the conference having learned something, and therefore makes it a meaningful time.
Writing Conference: This link provides ways to incorporate conferences into your class even when you have 100+ students. This can be done when the students are revising their work during one or two class periods.
