Abstract
This paper reports on research using the Questionnaire on Teacher Interaction
(QTI), and provides validation data for the first use of the QTI with a large
sample of mathematics classes. The effect of teacher-student interpersonal
behaviour on the students' attitude towards their mathematics class was
investigated and the dimensions of the QTI were found to be associated
significantly with student attitude scores. The paper also describes how
mathematics teachers could use the QTI as a basis for reflecting on their own
teaching.
