Classroom dialogue and science achievement

Conclusion This study indicates the responsibility that rests with the teacher in an activity-oriented classroom as far as providing the structural support necessary for effective learning (Note 4). The teacher is acting as a “surrogate textbook”. Using their own organization of knowledge-albiet wrong or incomplete-teachers provide the structure that is lacking. As the results indicate, some teachers can do this better than others. A challenge for teachers and teacher educators is to devise ways to improving the structure and sequencing of classroom dialogue. The TSA Technique could help here in two ways. It allows a sophisticated analysis of dialogue, indicating specific areas of weakness which could then be remedied by appropriate training. A similar approach has been used successfully with text material to rewrite and restructure deficient segments (Clarke; 1973). It could also be used to produce ideal “templates” of various models of teaching (e.g. Brady; 1985) for use as a guide for lesson planning.
