ABSTRACT
The basic assumption of the opportunity to learn model is that there is no direct relationship between teacher behaviours and pupil achievement since all effects of teaching on learning are mediated by pupil activities i.e. pupil learning activities are central to their learning. In particular, the amount of time a pupil spends actively engaged on a particular topic is seen as the most important determinant of achievement on that topic. In this model, the pupil therefore becomes the central focus with the teacher seen as the manager of the attention and time of pupils in relation to the educational ends of the classroom. In other words, the teacher is conceived as the manager of the scarce resources of attention and time.
