Research
Dave has many different scholarly interests. For the past three decades, he has collaborated with several lead researchers in mathematics education in the development of learning trajectories for length, area, and volume measurement. More recently, he has collaborated with other colleagues to explore the role of higher dimensions in young adult fantasy literature, the factors that motivate students to learn mathematics at the middle school, high school, and university levels, and the use of graphic novels in the teaching and learning of the STEM disciplines at the middle school, high school, and university levels.
