Resumen de The influence of attention on mathematical knowledge of teachers and lecturers: a comparison
This article reports on some findings from the project �Analysing the Transition from Secondary to Tertiary Education in Mathematics�. One of the key variables in the school to university transition is the teacher/lecturer, and here, we deal with the data analysing secondary teachers� and tertiary lecturers� responses to four mathematics questions. Elsewhere, we consider knowledge, preparedness, teaching style, etc., but this article tracks the ability to use mathematical procedures. We hypothesize that this is a function of what we pay attention to, as described in Mason's discipline of noticing. The results reveal that many teachers and lecturers fail to notice the necessary conditions for problems that imply that procedures are not always applicable. Possible reasons for this along with implications for student learning are discussed
