Effect of teaching practices and literacy knowledge on classroom interactions at the beginning of schooling

Classroom interaction is a key element in the teaching-learning process. Our aim was to determine the impact of teaching practices, children's initial knowledge of written language and children's linguistic condition on the dynamics of classroom interactions in the course of reading and writing activities. We followed longitudinally 205 students from kindergarten to first grade and examined the interactions in which they took part according to the agents involved and the function interactions fulfilled. Results showed an increase in the frequency of interactions as school level increased. Teachers had a predominant role as interaction agents and teaching practices and students' initial literacy knowledge had a significant impact on the distribution of the interactions. Monolingual students with non-instructional teachers and a high level of initial knowledge participated in a higher number of interactions than bilingual students with instructional teachers and a lower level of initial knowledge. We suggest encouraging peer interaction as a means of promoting knowledge construction processes.
