Educational Psychology Research Colloquium - Andrew Zieffler - February 17, 2022

My research interests are in the teaching and learning of statistics and data science. I am also interested in measurement and assessment as it relates to statistics education and data science research. A further interest if mine is in statistical computing and in thinking about different ways to integrate computing into the statistics curriculum. I am currently a co-PI on a National Science Foundation (NSF) funded project, DSC-WAV, which engages teams of data science students to assist community-based and non-profit organizations tackle their data-based problems. This collaboration helps the organizations and also offers the students valuable hands-on data science experience.
