Language for the Social Construction of Knowledge: Comparing Classroom Talk in Mexican Preschools

This study compares two sets of matching classrooms in Mexican preschools over a period of a year. In one set of classrooms the children improved significantly in independent problem-solving. We looked at videotape and transcripts taken over the year to see, retrospectively, whether the reasons for the improvement in problem-solving could be found in the classroom language. Differences in the two sets of data were explored with a method for investigating classroom talk which combines qualitative interpretation with computer-based analysis. This method had been developed to explore peer classroom talk in the UK and was being applied in a new context. A sociocultural model of how children learn independent problem-solving was also developed and applied to the analysis. This model was found to fit a number of types of teaching and learning exchanges found in the classrooms where problem-solving increased. The method used also enabled us to isolate several specific verbal strategies which carried the social c...
