Middle school teacher and author Cris Tovani describes how--after years of feeling frustrated about the time spent commenting on students' work only to find their work didn't improve--she changed both how she responded to student work and what she did with the information such work revealed to her. Tovani changed the timing of her feedback and streamlined the process so it didn't take too much of her time. Rather than spending most of her time grading final papers and assessments, she began giving more ongoing feedback while her class worked on writing assignments or read a text together--commenting before the final product was due so students would have time to revise. Tovani shares tools she developed to gather feedback from her students about what they do and don't understand, as well as procedures she uses to let that feedback shift her instructional methods accordingly.
