Abstract

This chapter investigates the internal structure of informative/explanatory mathematical writing (MW) as a latent variable. The study defines it as written communication in mathematics to explain and describe one's problem solving and reasoning by using mathematical language and representation. To assess the dimensions of MW, ten scales were developed based on literature and expert reviews to quantify students' MW performance. The dataset utilized for statistical analyses consisted of MW samples from 153 4th-grade students attending a public school in a Mid-Atlantic state. Through exploratory factor analysis (EFA) conducted on the three MW prompts, two factors emerged: mathematics problem solving and reasoning and writing. Subsequently, a confirmatory factor analysis (CFA) was conducted, resulting in a cross-factor loading of reasoning onto both factors. The role of representations in MW remains uncertain. This finding contributes to an understanding of the underlying dimensions, as well as offers a validated approach for assessing MW.
