The mathematics are distinguished by a particular privilege, that is, in the course of ages, they may always advance and can never recede.
~ Edward Gibbon
Field-workers visit schools. During school visits they engage in a variety of activities that are negotiated with the principal and the teaching staff, including support in developing teaching programs, curriculum interpretation, selections of learning materials and assessment. The teaching process is observed and help is offered with curriculum interpretation, methodology, pedagogy and assessment strategies.
