FracVisET: Investigating Fraction Visualizations using Eye Tracking
The project FracVisET (Investigating Fraction Visualizations using Eye Tracking) deals with visualizations for fractions (especially tape diagrams). The main focus is on the question which types of visualizations are particularly suitable to support the development of magnitude concepts for fractions in students. In order to draw conclusions about cognitive processing, eye movements are measured with eye-tracking.
