## Areas of Interest

Teaching and learning of rational numbers for children in grades 4-8, fraction learning in 4th & 5th graders, teacher preparation and development

## Research Interests

I have been working in the area of teacher preparation for over 20 years. I have taught mathematics methods courses for pre-service elementary education majors and similar courses for in-service teachers at the graduate level. I teach graduate courses and advise doctoral students in mathematics education. I started my career as a Title I mathematics teacher in a K-6 setting and have taught mathematics to students at the middle-school level, as well as adults in the General College at the University of Minnesota.

As a member of the Rational Number Project (RNP) team, my early research interests focused on the teaching and learning of rational numbers and proportionality for children in grades 4-8. RNP publications addressing fraction and proportionality learning can be accessed at www.cehd.umn.edu/rationalnumberproject.

The National Science Foundation has funded my most recent research ($550,000). The goals of this project are (a) to better understand why middle-school students have difficulty working with fractions and decimals in a meaningful way, (b) to construct an instructional module to overcome these difficulties, and (c) to create an online workshop for teachers to support their use of this instructional module. The curriculum module will be a companion to the Rational Number Project (RNP) fraction lessons created with previous NSF support, and will meet the 6-8 National Standards for fractions and decimals as stated in the NCTM (2000)*Principles and Standards for School Mathematics*. This research/curriculum development project has been done in partnership with the Minneapolis Public Schools.
