Current Research

Making comparisons among algebra, statistics, and calculus students' success with and ways of using and interpreting symbolic representations of quantitative relationships described in words; documenting and examining relationships between success with symbolic representation and course grades; identifying and classifying types of symbolic representation errors.

Research Interests

College students' interpretations of algebraic variables and statistical graphs.
