Exploring The Relationship Between Orpda And Teachers' Conceptual Understanding Of Place Value, Jamie Howard Price

Doctoral Dissertations

The purpose of this case study was to understand whether or not the use of an invented number system, called Orpda, helped teachers develop a deeper understanding of place value in hopes that this will translate into their own teaching of place value concepts.

Data were collected from teachers’ reflections on various activities related to Orpda, pre- and post-Orpda concept maps teachers created, online discussions between the teachers, teacher demographic sheets, and an interview with the instructor of the course.
