Teaching quality during mathematics lessons

This presentation focuses changes in elements of teaching quality during three parts of a mathematics lesson; start, middle and end. 64 grade 7 lessons were analysed using these partitions, forming a time series that shows decreasing quality for most elements (e.g., Modelling) from start to end of a lesson. Few elements showed an increase of quality (e.g., Intellectual Challenge). The structure of the lessons (whole class at start and individual work during middle and end) may partially account for a possible decrease. Even so, a decrease in quality is not desirable and implications on students’ learning are of concern.
