A Holistic Mathematics Curriculum Revision: An Adelphi University Case Study, Salvatore J. Petrilli
A Holistic Mathematics Curriculum Revision: An Adelphi University Case Study, Salvatore J. Petrilli
Journal of Humanistic Mathematics
Join me as I take you on a journey with the faculty of the Department of Mathematics and Computer Science at Adelphi University during our two-year re-envisioning and implementation of our mathematics curriculum. From the beginning this involved a data-driven initiative that naturally led to the revisions. Here I describe in detail the process that our department followed. In closing I end with some recommendations for interesting research directions in the field of mathematics education.
Dnr-Based Curricula: The Case Of Complex Numbers, Guershon Harel
Dnr-Based Curricula: The Case Of Complex Numbers, Guershon Harel
Journal of Humanistic Mathematics
DNR is a research-based framework which seeks to understand fundamental problems of mathematics learning and teaching. This paper discusses DNR with a particular reference to a curricular unit on complex numbers. Originally designed for college-bound high school students, the unit is structured to progress along a path that roughly parallels the development of complex numbers in the history of mathematics. We have tested the unit in three teaching experiments with inservice and prospective secondary mathematics teachers. The results from these experiments demonstrate the ways of thinking afforded and targeted by the unit. The correspondence between these ways of thinking and …
