This article presents descriptions of and examples from qualitative ca
se studies of 3 high school classrooms in Norway and the United States
. The focus is on how classroom discourse and writing interact with ea
ch other and provide an important and unique instructional resource. T
he leachers in 2 of the classrooms consistently elicited, overtly valu
ed, and helped develop student opinions and ideas. In this process, au
thentic questions and uptake were common, and a great diversity of voi
ces was heard. Bakhtin's and Rommetveit's dialogical framework is used
as the basis of analysis, as is Lotman's theory about the functional
dualism of texts. The main argument is that the interaction of oral an
d written discourse increased dialogicality and multivoicedness and th
erefore provided more chances for students to team than did talking or
writing alone. In this way the texts, both oral and written, were use
d to generate thoughts and opinions.
