Mathematics Faculty Publications

Taking into account the nature of mathematics as an exact science and the essential role of mathematics teachers’ knowledge of fundamental mathematics definitions; the authors investigated the pre-service secondary mathematics teachers (PSMTs) knowledge of a good mathematics definition in their group video-lesson presentations related to algebra; geometry; descriptive statistics; and number theory. The quality of their definitions can provide a glimpse of their preparedness to teach mathematics at the secondary level. Drawing on Leikin and Zazkis’ (2010) framework to analyze teacher- generated definitions; and Borasi’s (1992) characterizations of a good definition; the authors developed an analytical framework to analyze a …
