Abstract
A previously reported coding scheme for describing student expository
writing in mathematics has been developed into a set of descriptors aimed at
reflecting the level of understanding being demonstrated in the writing. The
original coding scheme provided a detailed analysis of the content of the
writing to enable the application of the descriptors. The descriptors are
intended to give researchers and teachers indications of the content of writing
tasks which may help advance students' thinking. Examination of writing
examples mainly from year 8 students has shown that it demonstrates little
conceptual understanding of mathematics.
