Usability Testing
We conducted usability testing, collected quantitative data and recruited participants to test the usability of the case study: MADE Ratio. For analysis we used R (https://www.r-project.org/). The goal of this study was to determine if this system can motivate and engage students in learning ratios and proportions. The affective strategies and the Leap Motion Controller were well suited for this environment (pdf).
