An analysis of pre-service teachers’ pedagogical content knowledge about story problem for division of fractions. (Korean. English summary)
J. Korean Soc. Math. Educ., Ser. C, Educ. Prim. Sch. Math. 19, No. 1, 19-30 (2016).
Summary: This study examined pre-service teachers’ pedagogical content knowledge of fraction division in a context where they were asked to write a story problem for a symbolic expression illustrating a whole number divided by a proper fraction. Problem-posing is an important instructional strategy with the potential to create meaningful contexts for learning mathematical concepts, especially when real-world applications are intended. In this study, story problems written by 135 elementary pre-service teachers were analyzed with respect to mathematical correctness, error types, and division models. Patterns and tendencies in elementary pre-service teachers’ knowledge of fraction division were identified. Implicaitons for teaching and teacher education are discussed.
