Pupils’ spontaneous questions and statements represent interesting research material from the point of view of the effects they have on the actions taken by the teacher (explanations, assessment, control, etc.) as well as on the kind of knowledge pupils acquire (about the world and about themselves) as a consequence of the teacher’s actions. The research into the functioning of children in the course of educational activities described in this article is merely an example of possible attacks on the problems of subjectivity. The research results enrich the present knowledge of the teacher’s actions (taken in connection with students’ knowledge or lack of it). They also point to the possibility of further research into students’ spontaneous speech at various levels of education.
